Details reports in The Autocar.
36. Peugeot Freres. The diagonal form of motor is adopted by this firm for their motorcycles, and is of 2 h.p., but with a very low weight of 77 lbs. only. It presents much the usual appearance, but differing in many respects in a large number of minor points, where the comfort of the rider has been studied. A special form of saddle reduces vibration. A 4.5 h.p. quad. is shown for two passengers; water-cooled engine, with radiators fitted over the driving axles on each side of the back seat. Care has been taken to produce a very elegant form of quad at a low price.
There is also on view a single roller 1/2 inch pitch chain from 1/8 inch upwards, and the price for which works out cheaper than the lowest English-made.
105. Ariel Motor Co., Ltd., Bournbrook, Birmingham. The New Ariel motor-bicycle has a 2 h.p. engine, vertically bolted into the frame between the bottom bracket and front wheel. The steering head of the bicycle is strengthened by the addition of an outside tube from the front fork crown to the clip at top of head. The Ariel engine has the sparking plug screwed directly into the centre of the combustion chamber. A large tank is fitted in the frame, which holds two gallons of petrol, the bottom of the tank composing the well-known Ariel carburetter, holding a quart of spirit. Both inlet and exhaust pipes and valves are extra large, and, the silencer is really a silencer, being a cylindrical box with three perforated partitions — this is very successful in muffling the exhaust. V pulleys and Lincona belt are used. Lubricating oil and batteries are carried in a small additional tank.
76. Bradbury and Co, Oldham, have in their new motor-bicycle struck out on somewhat new lines. The engine is placed vertically, and the case of the engine is a malleable casting in which the whole of the lugs and the crank bracket shell are included. Consequently the crank case of the engine can, without any fear of fracture, be used as part and parcel of the frame. The pulley side of the crank case is an aluminium plate. The cylinder dimensions are 66mm. bore by 76mm. stroke. The cylinder is cast in one piece with the head, and the silencer is placed close to the exhaust outlet. A surface carburetter is provided, but a spray is optional. A wipe contact is used with a Peto and Radford accumulator, and a trembler coil with Carpentier trembler. The positive terminal of the contact breaker has a spring behind it to keep it always up to its work.
The connections for the wiring are exceedingly simple and effective, as they are effected by spring snaps. The first movement of the exhaust valve lifting lever cuts the current. Lubrication is provided by a pump placed conveniently at the fore part of the tank, where the oil reservoir is situated. The drive is through a Lincona belt, the gearing being about seven to one. The girder front forks are particularly good. On a 2.5 h.p. machine shown there is provided an extra rear seat readily attached and detached, and carrying an extra tank, with compartments for both oil and petrol. The rear passenger places his feet on a pair of pedals provided for the purpose. A well-designed trailer is exhibited, and a motor-bicycle driven by a Clement engine with a chain drive is also shown.
145. Lycett's, Ltd., Birmingham. This firm is showing a good collection of tool bags and saddles. The Ark Motor bag shown, which, as its name implies, is somewhat in the form of a Noah's Ark, is provided with two sets of straps, so that it may be fitted to the back of the saddle or upon a carrier. It is fitted externally with a small pocket at each end, and internally with loops and pockets for tools, repair outfit, etc. It also has a strap to carry a cape on top. Another bag shown is divided into two parts, one being for an accumulator, and the other for tools. This latter is made to be carried by the tor) tube of a machine. A large square bag, which is intended to be carried behind the saddle, is fitted with an extra strap to attach it to the saddle frame.
11. Enfield Cycle Co. Ltd., Redditch, show two quads, one tricycle, and three distinct patterns of motor-bicycles. One of these has the Minerva engine and fittings, with mechanically-operated inlet valve, the speciality being the Enfield front forks. No. 2 has a 2 horse-power air-cooled engine, bolted vertically in the frame, in such a forward position that the pedal cranks miss the belt and contact breaker, so that bearing width in the engine has not been sacrificed, being 1.25 wide on each side. Drive is by a three-ply V leather belt, to pulley with extra wide flange, through which the spokes of the driving wheel are threaded.
The third machine has a 2.25 h.p. water-cooled engine, bolted vertically in the frame; the timing shaft forms the driving shaft, but, instead of being at a two to one ratio, the reduction in speed is six to one, the necessary exhaust lifting and sparking cams being made in triplicate on the large tooth wheel; no other gears are used. The timing shaft issues from the crank case at the opposite side, and carries on its extremity a driving chain wheel containing a spring clutch, from which the drive is conveyed to the back hub by a special chain. The front compartment of the tank contains the cooling water, one and a half gallons being carried; 18ft. of 3/8 inch aluminium piping, formed into a radiator, is coiled in the space between the tank and down tube. The weight complete, with petrol and water, is 140lbs., price 75 guineas, and speed 30 miles per hour. This, however, can be easily altered by changing the rear sprocket wheel. In quads, the well-known Enfield type is retained, fitted with either 3.5 or 2.75 water-cooled De Dion engines, and Bozier two-speed gear, worked by lever at drives side; the quads sell at about 120 guineas, according to power.
134. South British Trading Co, London, E. C. This firm is showing two new pattern powerful 20th Century lamps for motorcycles. They are both fitted with large parabolic reflectors, made of aluminium rolled on brass, and are very powerful light-givers. One of these lamps is for oil and the other for acetylene, the latter not being fitted with a spring back, but with a bracket, which clips direct on to the head of the machine. It is finished black (gun metal), and has a very taking appearance. This firm is also showing some useful wrenches, having curved handles, specially suitable for motorcycles.
3. Carlton Motor Co, Cricklewood, N.W., have a full line of finished motors of 2 h.p., 2.5 h.p., and 3 h.p., for bicycles, and 5 h.p. single cylindered and 10 h.p. double cylindered water-cooed motors for cars. Complete sets of castings are supplied, and these are of excellent finish and design. Connecting rods are steel forgings, and for bearings a very high grade of phosphor bronze is used, and a fine aluminium alloy for the crank cases.
The well-known Carlton carburetter has undergone considerable improvement, with the addition of a positive measured petrol feed, and this ensures very economical working. The workmanship on this carburetter is of the best, and the makers will readily adapt them to any make of machine. The firm undertake all kinds of repairs to motors, and guarantee their work in all respects.
87. Osmonds, Ltd., Birmingham, show three specimens of Osmond motor-bicycles. In these the engine is clamped to the tube from head to bracket, the outside flywheel balances the weight of the engine, so that the total weight is central; drive is by twisted raw hide belt, running over a jockey pulley on main tube of frame. The claim of Osmonds, Limited, is, not that they have produced a racing motorcycle, but that their machine is still a bicycle, with the addition of an engine capable of propelling the machine and rider at the rate of 30 miles an hour; the weight of the complete machine is only 721bs., so that the engine has not got a heavy load, and can put forth its best efforts with the least possible handicap. Although bicycle parts have been used throughout, strength has been increased where necessary, and replacements can be made with facility at bicycle prices — a good point.
All Osmond motor-bicycles are fitted with the patent "Radilever" front rim brake, which can be swung from one side of the handlebar to the other, or placed in any position desired by the rider, without interfering with the adjustment of the brake. Belt pulleys are spoked into the back wheel rim; either back-pedalling hub brakes or hand-applied rim brakes are used, according to taste.
Another pattern is shown having a chain drive and a two-speed gear, the engine being in the same position as on the previous machine, driving by chain to an additional bracket, placed a few inches in advance of the usual bottom bracket; this extra bracket carries the two-speed gear, which is on the sun and planet system, giving a reduction from high to low of 25 per cent. This enables the machine to mount any hill. The price of the belt-driven machine is £45, and the chain-driver, with two-speed gear, is £50.
158. The Birmingham Pneumatic Tyre Syndicate, Birmingham. The Woodstock motor tyre has bands of steel in sections in the edge of the tyre, and when in position these stand vertically in the rim. They are held in position and prevented from slipping in the bed by means of bolts, which engage with them through holes pierced in the rim.
69. Chambers Engineering Co, Birmingham, show three Royal Mail motor-bicycles. Number 1 has a Clement-Garrard engine driving through chains, a cross framed cycle being used. The combination is exceedingly good.
The second pattern has a 2.75 h.p. engine in the Kelecom position, also driving through a chain. The third pattern has a 3.5 h.p. engine in a vertical position, and with outside fly wheel; spray carburetter, large petrol case, and battery tank belt drive, whilst the control is by two levers on the handlebar. This machine is a fine piece of work. The price is £50.
125. Humber, Ltd., Beeston and Coventry. Seven motor-bicycles are shown, all of the Standard Humber chain-driven type.
A resuscitated Olympia tandem is on view, with 3 h.p. engine, chain-driven, spring seat-pillar, and a luxuriously upholstered wicker seat between the front wheels, in which a passenger (lady preferred) can be carried. Wipe contact is employed on all Humber motorcycles, the trembler being on the coil.
The Humber chain-drive is perhaps too well-known to need further description, but we might just remind novices that the engine is hung on four pillars which replace the usual tube from head to bracket: the drive is taken by chain No. 1 from engine cog wheel to large chain wheel on bottom bracket spindle; inside this chain wheel is a smaller one, also fitted on the spindle, but running on a free-wheel clutch; from this chain wheel chain No. 2 runs to the back wheel hub. On the other side of the machine is chain No. 3, which is used solely for starting purposes; chains Nos. 3 and 2 are interchangeable as to length, so that any undue stretch in chain No. 2 is counteracted by swopping chains.
Free engine is obtained, so that the engine can be idle when the machine is running downhill, and so get an additional chance of cooling. Ample brake and mudguard accommodation is provided on all Humber motorcycles. The same disposition of engine, chain-drive, etc., is employed on the Humber motor-tricycle, the engine being situated within the wheel base, and the weight carefully distributed. Prices are as follow: Motor-bicycles, Coventry-made, 1.75 h.p., £50; 2.75 h.p., £55; Beeston-made, 1.75 h.p., £60; 2.75 h.p., £65. Tricycles, Coventry-made, £65; Beeston made, 75 guineas.
67. Clarke, Cluley and Co, Coventry, show the Globe motor-bicycle, with a trailer attached. The engine of 2.25 h.p. is placed vertically in a loop frame: it has a spray carburetter, large tank, and battery and coil case, two brakes, and generally is on accepted lines. The framework of the trailing car is of ample strength.
192. Ross, Courtney and Co., Ltd., Upper Holloway, N. Like all enterprising cycle accessory people, this company are now catering for the wants of the motoring public, and in the Gallery have a display which includes lubricators, horns, lamps, valves, etc. Special productions of theirs are tyre inflators, and among the several specially adapted for motor work we noticed a foot pump fitted with pressure gauge registering up to 100 lbs. per square inch. It is provided with a large handle, while the "feet" are hinged, so that they fold up when not in use, and so occupy but a very small space.
242. Stanley Feast and Co., Ltd., London. The main feature to which attention is drawn at this stand is the "S. F." repair band for motor tyres. It consists of a thin pliable band, from 3.5 to 4.5 inches wide, and is intended for the quick repair of bursts, cuts, gashes, or weak places in outer covers. One end of the band is placed under the wired or beaded edge of the tyre, the other end slipping under the opposite edge. In the event of a very big gash, two bands, slightly overlapping, may be used. Tyre repair outfits, solution, and tyre cements are other specialities of this company, who are also introducing an enlarged model of their "S. F." tyre remover and spanner, adapted for use on motor-bicycles and cars.
84. Ormonde Motor Co, London, W., have a fine show of motors of 2.25 and 2.75 horse-power, all of which are fitted with the Kelecom engines, in a vertical position, fastened in the rear section of the frame. The engine rests upon the chain stays, and is clamped to the seat pillar. Specially strengthened head and front forks are fitted. The silencer is carried underneath the bottom bracket.
Machines are all fitted with the Ormonde special V section belt. The tank capacity is 7 quarts, capable of driving the machine 170 miles. A special indicator fitted on the outside of the tank is moved by a float in the petrol, and shows the exact quantity in the tank. The contact breaker and valve lifter are combined, working with a twisting handle. The control is effected by two levers, one for advancing sparking, and one for the throttle. Valves on the machines exhibited are all increased in size from those of last season.
Automatic lubrication is fitted, and a light gauge for the oil is fitted on back tank. Ormonde front rim brake and Bowden on the back are fitted to all machines. Prices £45.
A lady-back motor tandem is also to be seen here, fitted with a 2.75 Kelecom engine, and is worthy of an inspection by those who intend going in for this form of motoring, all the Ormonde specialities being embodied in this machine, which is listed at £60.
The Ormonde fore-carriage, selling at 12 guineas, is exceedingly well designed. It is quickly attached and detached, and on removing the front wheel of the cycle and fixing up three clamps, a cycle is converted into a three-wheeled two-seated car.
24b. Maurice Knapp, Dunstable, Beds., shows a cup drawer, which is of an adjustable form, capable of extracting the tightest cup in the bottom bracket of a cycle or motor. Also a useful form of lapping tool for making joints, extremely useful to the frame builder. And also the M. and. P. motor stand and luggage carrier, serving the dual purpose of a stand and home trainer, and also when turned up as a luggage carrier and when not in use it can be folded up. It also affords the facility of removal of the wheel, a thing to be desired, whenever the puncture fiend should be about. We consider a stand of this nature an absolute essential.
24. A. G. Quibell, London. A folding stand of a double triangular form, with strong base is shown here. The sides are hinged, and fold down into the base plate, thus enabling the whole to be easily stowed away. A pair of clips suitable for fixing to any form of chain stay are supplied and used when it is necessary to remove the wheel.
143. Bransom, Kent and Co., Ltd., London. At this stand are exhibited a number of parts particularly interesting to the trade. A motor-bicycle of parts made by this firm is on view fitted with a Minerva engine.
A number of engines of various makes are on view, amongst which is a genuine De Dion motorcycle engine, which has only recently been put on the market. A very neat oblong metal case to carry a spare accumulator is shown, fitted with clips to attach it to the frame of the machine. A special motorcycle hub is shown, which should give great satisfaction. Several forms of new lubricators are on view, also spare petrol tanks, carburettors, and a small oval topped funnel which can be readily carried in the tool-bag.
101. E. M. Bowden's Patent Syndicate, Ltd., Brook Street. E.C., show a frame with a special cradle to take any design of engine. The pedals and chain wheel are placed ahead of the engine, thus making a lengthy wheel-base. The machine is driven by chain and Bowden clutch, with the ordinary form of conical faces, but thrown in and out of gear by the Bowden wire, which permits a free engine at will. The claim that this firm has a design of machine adaptable to every form of engine operated entirely from the handlebars by the well-known Bowden system is clearly evidenced, as they show the frame fitted with various well-known makes of motors.
A handy system of lubrication, which enables the rider to accurately measure the quantity of oil delivered to the crank chamber, is smart. It consists of a glass cylinder with a central rod or spindle having a valve at each end, and when screwed down the oil enters the chamber from the tank; when screwed up it shuts off the tank and opens the connection to the crank chamber. The action of applying the brake cuts off the current, and this can be graduated to suit the requirements of the rider.
24d. The Clissold Cycle Co., London. Double stand for use when cycle is standing or at rest. The handlebar being fitted with a roller and cord permits of the drawing up of a pair of small wheels attached to a bracket, to be used in traffic and slow riding when it is required, either to stand still or proceed so slowly to render the balance difficult.
111. D. Citroen, 45, Holborn Viaduct, E.C. Minerva motors are this year displayed on a well-designed and somewhat ornate stand, and an excellent, effective show results. The motors shown are the new 2 h.p. Minerva, the 2.5 h.p. Minerva, and the 1.75 h.p. Romania.
The new 2 h.p. engine is full of improvements. The notable alteration is in the mechanical operation of the inlet valve, which, although opinions may differ, is unquestionably an effective, reliable and efficient method for the induction of the gas. We notice one point to which attention has not yet been called, and that is that the valve stems are lifted by a plunger working in a straight line and not at right angles, as in the earlier pattern engines. The new engine has a plug in place of the compression tap, has the sparking-plug immediately over the inlet valve, has all angles removed from the exhaust pipe, and is fed through a very neat and simple spray carburetter. A milled-headed nut permits of throttling of the engine, but this is open to improvement, so that it can be worked by a lever. For those who like to drive on the exhaust valve, it is open to fit a Bowden exhaust lifter. The lifting of the valve in order to free the engine is provided for in the present design by the full retardation of the contact breaker. The absence of the lower radiating ribs vastly improves the appearance of the motor.
In the 2.5 horse-power engine no changes have so far been made, but later on in the new year the mechanically-operated inlet valve will be introduced.
The new Romania engine is on old Minerva lines, fed through a spray carburetter, and with a hand lever for lifting the exhaust valve. The motors are all shown in working section, so that even the novice can gain an excellent idea of the motor system. Despite the introduction of their own engines by many motor-bicycle makers, the Minerva engine enjoys even a greater popularity than ever, for it is to be found throughout the show.
109. J. Van Hooydonk, London. One of the earliest makers in the cycle trade to recognise the claims of the motor, J. Van Hooydonk, of Holloway, N., has reaped the reward of his enterprise, and has had the enjoyment of selling Phoenix motorcycles in large quantities, and wherever the Phoenix has gone it has given pleasure and satisfaction to its owner.
Mr. Hooydonk is in every sense a practical motor engineer, and his machines, therefore, bear the stamp of his genius, which has been directed to the simplification of the machine, of the work of driving, and of repair or adjustment when need might arise. The standard Phoenix is made in two patterns. The first is driven by a 2 h.p. Minerva engine, with mechanically-operated inlet valve, and the latest of improvements. The lifting of the exhaust valve in the Phoenix is independent of the contact breaker case, being done through a Bowden wire. Spray carburetter is used, and the transmission is by a three-ply V-shaped belt of chrome-dressed leather. A new form of belt fastener is adopted, in which the fraying of the hole in the belt is avoided. The oil pump is elevated on the top tube of frame, and the feeding of the lubricant is certain and easy. The front forks are trussed. Two accumulators are carried in each machine, and the petrol capacity is two gallons.
The 2.5 h.p. machine has a Longuemare carburetter, with levers to adjust both air and gas, and the admission of hot exhaust gas for warming the carburetter can be regulated as necessary. The silencer is particularly good.
The "Trimo," the latest Phoenix production, is really a combination of a cycle and light car. A fore-carriage, with a nicely-upholstered body, well hung, is borne on a pair of wheels, and is bolted to the cycle frame at four points, converting the cycle into a three-wheeled car. The steering is connected to the front forks. A few minutes' work, including replacing the front wheel, re-converts the machine into a bicycle. The front seat of the Trimo is very comfortable, and is certainly an improvement upon the trailer. The Trimo is priced at £65. With wicker body it is £5 cheaper.
The Phoenix tandem has the engine (2.5 h.p.) centrally placed in a cradle, is fed through a Longuemare carburetter, and is exceedingly well-designed and easy to control. The number of Phoenix lady-back tandems in use shows the popularity of this type.
47. The Swain Patents Syndicate, Horwich, Lancs. Here are to be found the Swain and Horwich Tyres. The special advantages claimed for these are durability, speed, ease of manipulation there being no wires — and freedom from punctures. They are built up expressly for motor work, a special feature being that both covers are interchangeable, and they fit any of the standard pattern rims.
56. Clipper Pneumatic Tyre Co, Coventry. Here are found motor tyres of all descriptions, their speciality for motor-cyclists being the Reflex motor- bicycle tyre, which is made in 26 and 28 by two inch sizes, and similar in pattern to their ordinary Clipper-Reflex, so well known to riders of the pedal-propelled cycle. The tyre is built up of specially strengthened fabrics, and there is ample thickness of rubber on the tread. Their tyres are mostly supplied on a special motor Westwood rim.
50. Continental Caoutchouc and Gutta Percha Co, 64-5, Holborn Viaduct This exhibit will be the first to catch one's eye on entering the Hall from the Upper Street entrance, its general appearance being very pretty. A good show of motor tyres will be found here, and as the price of their motor-bicycle tyres has been considerably reduced, there is but little doubt there will be a larger market for them, all tyres being thoroughly tested before being sent out. The company are making a speciality this season of repairs to ail kinds and makes of motor tyres.
58. Palmer Tyre, Ltd., Birmingham. The motorcycle tyres at this stand are well worthy of inspection. The well-known Palmer Fabric is used, every thread being separated and cushioned in vulcanised rubber, which renders them very resilient. The tread is very thick and almost puncture-proof, ordinary tacks failing to find their way to the inner tube. The Palmer is moulded to a special shape, so that when inflated, the rubber is under compression, and the tyre takes a form entirely different to that of other tyres. This perhaps accounts for the absence of side-slip, which is practically unknown with this new tyre.
29a. Cheswright and Co, London, S.E., show the Lamaudiere motor-bicycle, constructed by the French company of that name, of Paris. The engine forms in itself part of the frame, viz., the diagonal, has an outside fly-wheel and is of 2.25 h.p., driving with a raw hide twisted belt, the underside passing over a jockey pulley, which can be adjusted from the top bar by a lever with a ratchet stop action. The spray carburetter is of novel form, the spirit being delivered on gauze wire; there is an adjustable drum above the gauze wire which regulates the air supply, and is operated by a lever on the top bar. The carburetter is enclosed within a chamber, which is heated by the exhaust gases. Alcohol or other spirits can be used with this carburetter. An exhaust lift is fitted, and the switch is within the left handle. A notable feature is that the driving pulley is one piece with the rim, the back brake acting on the driving drum. Considerable ingenuity has been displayed to render this machine a very compact as well as strong one.
157. Steiner and Co, London, E.C. A very large range of horns is here shown, with one of which is combined an oil lamp, placed in the mouth end; another shows an acetylene lamp combined in the same manner. The Powerful and Motocyclite acetylene lamps, both of which burn six hours, and the Belmont, which has made a reputation, are three good lights.
167. The Garrard Mfg. Co., Birmingham, have five complete machines on show, and the actual four-cylinder machine that went up Gaillon Hill at 62 miles per hour. There are two of the chain drivers and one belt drive pattern shown.
The well-known featherweight motor is shown in section, and all the parts can be readily inspected. The two-speed gear machine and parts can also be critically examined. The chain driver, with two speeds, has been exhaustively tested, and is a really fine piece of work. Minor improvements have been introduced into the belt driver, chiefly in the disposition of the accumulator and tool bag. The new contact breaker, known as the Garrard-Maxfield, is a distinct improvement. The demand for the featherweight sets and machines complete is, we hear, very great, and the firm is working at high pressure to cope with the demand. The construction of the Garrard-Maxfield Contact will be readily understood from the illustrations. It is designed to give an exceedingly quick break. This is effected by two spring-controlled plungers separating the platinum contacts so quickly as to prevent the formation of an arc between them, with the consequent rapid wear and weak secondary spark. This new principle the firm claim to give splendid results, firing the motor at even the high speed of 3,000 revolutions a minute even with two volts only on the primary. We intend putting one of these new fitments to a practical test shortly. It is readily attached to standard. C.G. motors by simply unscrewing the old pattern contact breaker and replacing with the new one. It is highly finished and small in size.
64. The London Machinists Co., Kingsland. This firm show the Royal Sovereign motor-bicycle, built throughout in their factory at Kingsland. The engine, which is vertical, is contained in a horizontal loop, to which it is securely bolted. The forward part of the loop is brazed to the main down tube, whilst the back part forms the bottom bracket. Surface carburetter, silent exhaust, and one lever controls the valve lifter and advance sparking. The wheel base is extra long, and a very steady machine is thus secured.
130. Goodyear Tyre and Rubber Co, 5, 6, and 7, Singer Street, Tabernacle Street, E.C. This firm are making their special motor-bicycle tyres in sizes 26 by 2, 28 by 1.75, and 28 by 2. The system employed in fastening is their well-known form of braided wire, i.e., a flat band of fine braided wire, which lies in either edge of the outer cover. The act of inflating the cover decreases the circumference of the band by increasing its width. This causes the tyre to contract on the rim. The firm's well-known form of motorcar tyre, with detachable side flanges, is also shown.
86. The Crypto Works Co., Ltd., have five motor-bicycles on show. These include three Crypto 2.25 h.p. and one 2.75, h.p. machines, and a featherweight, fitted with the Clement-Garrard motor. The engines of 2.25 and 2.75 horse-power are fitted in a vertical position, right in the centre of the frame. An ingenious switch and combined exhaust valve lifter is good. A special Longuemare carburetter is used, and the Lincona belt fitted. The petrol tank is of neat design and large capacity. The control levers are within easy reach of the rider's hands on the horizontal tube. A silencer of large dimensions is used, and wheels, hubs, and all frame parts are of extra strength. Dunlop or Clipper tyres are fitted at option, and the price of the 2.25 horse-power is £50, and the 2.75 £65. A Bowden back rim and a lever front rim are fitted, and the finish of the exhibit leaves nothing to be desired.
227. Alfred Dunhill, London, N.W. The name of Dunhill has become a household word in the motor-cycling world, as the moment one takes up motor-cycling it must not be forgotten that the extra speed attained necessitates extra clothing, and Mr. Dunhill is the man who has set himself out to supply the requirements in the most thorough manner. We have not space to refer to his many productions in the way of caps, goggles, leggings, etc., so must select one or two for special mention.
We first inspected the M.C. Semi-Breeches in cloth-lined twill material, and also in leather. These breeches are in the form of overalls, and whilst having the appearance of knickers, can be much more, readily put on and taken off. One of the most useful of Mr. Dunhill's articles for the use of motor-cyclists is his Umbrella Cape. There are no buttons on this whatever. You just stick your head through a hole, and there you are! It consists of a long loose cape of waterproof material, the neck consisting solely of rubber. The cape folds up into a very small space, and should find a place in all motor-cyclists' outfits, as it proves invaluable when the elements suddenly turn unkind, and the rain begins to fall — as it did on that memorable anniversary run to Oxford.
29c. East London Rubber Co, London, show a bicycle fitted with the Kerry engine, in a loop which allows the engine to be placed low, and at the same time efficiently forward to get a good length of belt drive, an automatic carburetter is fitted. The main feature aimed at has been to produce a neat machine, coupled with cheapness, 38 guineas retail. At the same time, nothing has been sacrificed as to strength and simplicity.
168. The Bowden Brake Co. Ltd., London, provide excellently for the braking of motorcycles, the famous Bowden wire being made of extra strength. The new Bowden front rim brake is made in two forms, one actuated by a lever, and the other by the Bowden wire. In the latter very neatly-concealed spring is used, and the brake should become popular in either form. Both are very easily attached. The The old cycling crack, R. J. Isley was met here, and reports fine prospects for the new season.
92 Imperial Cycle and Motor Co, Birmingham. The motor-bicycle on show at this stand has a neat appearance, the case, containing the accumulator, trembler coil, petrol, lubricating tanks, and carburetter, being of polished mahogany, a contrast to the metal cases we are so accustomed to see. The machine is fitted with a 2 h.p. engine in the inclined position. One lever operates the compression, mixture and sparking. The tank will hold sufficient petrol for a 100 miles ride. An automatic lubricator is fitted, and a very efficient silencer is carried underneath the bottom bracket. Price £42.
187. Salsbury and Son, Ltd., London, W.C. This firm entered early into the supply of motor accessories, and a very large range of such articles is shown here. The new rear light lamp, of insignificant weight, with red light, is a useful introduction. Leather coats and breeches, lighter than the usual sort, are introduced. A very powerful but neat horn is shown, the trumpet portion being bent to the form of the handlebar; the attachment of this is very good. The Invincible oil lamp for motor-bicycles is excellently designed for its purpose, and has an oil well of extra size. The E.I.C. sparking-plug is sold by this firm.
232. The Reliance Engineering Co., Southampton. - "Death to Vibration" is he motto this company has adopted, and so far as motorcycles are concerned they claim to have overcome this by means of their "N. A. B." anti-vibrating seat pillars and handlebars.
The seat pillar consists of a combination of spring and balls, which not only absorb the vibration but the balls surrounding the plunger, serving the purpose of breaking up the friction at any point of contact, so ensuring the perfect working of the spring. In fact, the makers claim that so thoroughly does the device take up the vibration that no springs in the saddle are required. The peculiarity of the pillar is that the spring-controlled telescopic tubes are pressed out in fluted sections to form seven longitudinal grooves, each accommodating a vertical row of steel balls. The Reliance Company have also adapted their arrangement to handlebars, with the result that motor-cycling over bumpy roads on a machine fitted with these ingenious devices loses much of its disagreeableness.
112. The Triumph Cycle Co., Ltd., Coventry, show their specially built frame fitted with the latest pattern Minerva engine, and they have fitted a very clever arrangement for regulating the throttle valve. A rod is fitted to the top rail to the throttle valve, the top end being serrated with a number of notches into which engage a small spring governing the amount of lifting.
29b. Oldsmobile Co., Ltd., London, show a motor-bicycle fitted with the Royal motor which is mounted within four tubes, which form the underside of the seat pillar. It has a steel cylinder, whilst the radiator fins are vertical and hollow, allowing the air to pass up freely. These fins are brazed top and bottom of the cylinder. Royal atomizer is used, which is composed of double chambers; these effectively spray the petrol. A novel form of silencer consists of a tube stopped at the end, having a large number of minute holes, the whole tube being bound with copper wire. The result is an almost complete absence of noise with the exhaust; 42 ampere hour accumulators are supplied, and the petrol tank is for 110 miles running. Two brakes of powerful construction are fitted; the whole of the working is done by two levers, close to the handlebars, the switch being on the left-hand. The drive is by one chain alone.
The well-known Oldsmobile light car is also on view.
91. Werner Motors, Ltd., 151a, Regent Street, have a very fine exhibit, comprising 11 machines. The Werner design has been still further improved for 1903. Two powers are shown, viz., 2 h.p. and 2.75 h.p. The carburetter is now fitted with a throttle, and is much neater than last season. All machines are Paris-built throughout, and the finish is most excellent, and will satisfy the most critical inspection. Brake gear is very substantial, the front rim brake being at once simple and most effective, and the rear brake is constructed on an entirely new principle. The tank has been altered in design, the accumulator being now placed in a centre compartment, and the capacity of the largest size tank is 150 miles; contact breaker and pulley also are quite on new principles. The tyres are Dunlop motor-bicycle, specially made for the Werner Company, Limited, with rims of Dunlop-Bartlett section. The free-wheel is on the Morrow principle, and hubs are of special strength. Timing gear is also made stronger, and the regulating levers are all within easy reach. Lubrication details are also improved.
144. C. Lohmann, Aldersgate Street, London, E.C. Here we find the well-known Perfecta acetylene lamp, which has given such satisfaction that no alteration has been found necessary. It is, however, now fitted with spring back or fixed back, as desired. Motorcyclist tool-bags are also on view.
142. W. A. Lloyd's Cycle Fittings, Ltd., Birmingham. A motor cycle is exhibited, fitted with one of their own make 2 h.p. engines in which the cylinder and head are cast in one piece. The bore is 2.625 in. and the stroke 2.875 in. The connecting rod end is made in two parts to provide for adjustment on the crank pin. A new contact breaker of registered design is fitted and also a new fork crown. A combination hub, having a ball-bearing ratchet free-wheel without springs and a large silencer make up a motorcycle which will no doubt give general satisfaction.
124. The Chase Cycle Co., Birmingham, show a motorcycle, 2.25 horse-power, fitted in a vertical position, within a loop of the frame, of which one side forms the double top bar, and the other joins the loop for motor. Automatic petrol regulator and carburetter, one lever control for exhaust valve and advance sparking. The engine is placed in front of bracket to ensure a long belt drive, and an outer ball-bearing on the driving pulley is provided, which prevents straining of the crank shaft.
153. Miller and Co., Ltd., Birmingham. The Edlite, the lamp specially adapted for motorcycles, is now fitted, when desired, with a prismatic lens. It is made in two sizes. A combination red and white light lamp is shown in which the red glass normally attached in front of the reflecting cone may be turned on its hinge against the side of the lamp, out of the way, and is retained in this position by a catch. The transparent lens is fitted at the inner end of the reflecting cone, which is held in position by a split spring ring, thus enabling the cone and lens to be removed for cleaning. Some large "Arclite" acetylene lamps for cars are also shown.
30. The Kitto Automobile Co., Ltd., Chiswick, S.W. The machines shown by this firm are of their well-known narrow type, and adapted so that the engine takes the place of the usual pillar tube, it being fixed at the bottom end to the bracket and the clown tube, and at the top end by a clip into which the seat pillar fits. The engine is 3.25 horse-power, and has combined mixing valve and throttle, or can be supplied with a float feed and spray carburetter. The top tube carries the lubricating oil, and the engine is supplied by a small force pump. There is a single lever to control the exhaust valve lifter and advance sparking. The battery and coil are clamped round the down tube, whilst the petrol tank is on the down stays. An exhaust box, capable of being cleaned, is an advantage. The driving pulley is securely fastened to the rim of the back wheel, not to the spokes. A provision is made within the, driving pulley on the motor to catch any oil which might work through the bearings. The prices range from 30 guineas for the 2.125 horse-power, to 40 guineas for the 3.25 horse-power.
13 (ARCADE). Robert W. Coan, Myddelton Street, Clerkenwell, E.C., shows all kinds of castings in aluminium in connection with cycles. Various novelties in the form of souvenirs, badges, medals, etc., may be seen here. Aluminium crank cases for motorcycles are made by Mr. Coan, who guarantees that castings can be made from a customer's own patterns in a single day.
31 (ARCADE). J. Van Hooydonk, 736, Holloway Road, N., shows the Smith Two-roller Spring Seat-pillar, which has been invented to help overcome the vibration trouble. Another exhibit is the new patent Anti-vibrating Handlebar, in which the springs, being very soft, respond to the merest unevenness of the road. The double guides make the bar absolutely secure, preventing side play and making it equal to a rigid bar.
32 (ARCADE). J. N. Birch, Nuneaton, shows two motor-bicycles, one fitted with Simms' Magneto in conjunction with Birch's advance sparking apparatus. This machine is constructed with Birch's patent combined crank chamber and bottom bracket built in the frame; surface carburetter, belt drive, Birch's disc hubs, and compound brake. The other has a surface carburetter, wipe contact, accumulator, trembler coil, and self-compenszing contact.
97. John L. Thomas, Barnet, Herts. The Celeripede motorcycle shown here, fitted with a 1.5 h.p. Celerimobile engine, 62 bore and stroke, with a two lever control and spray carburetter, should prove a good investment at the moderate figure of £40. Fitted with a Minerva 2 h.p. (1903) engine, the same machine is listed at £45 nett. The weight, 89lbs., does not appear to be excessive.
A new type engine will be supplied, with an extra long wheel base, large silencer, and long bearings of large diameter. A motor-tandem (also called the Celeripede), and fitted with a 1.5 h.p. Minerva engine, belt driven, is also on view. Any of these machines may be supplied with a patent spring fork, which is fixed to the front hub spindle, and by means of which vibration is very considerably lessened.
250. The Birmingham Small Arms Co., Ltd., Birmingham. While not taking up the manufacture of motor-bicycles themselves, the well-known B.S.A. Company are not overlooking the growing popularity of the motor-propelled machine. A set of cycle fittings, specially adapted for the building up of motor-bicycles, was introduced last year. To meet the demand for a frame to stand the strains of the increased power of the motors now being used, and the consequently larger size of tyres, a new set of fittings has been introduced for the 1903 season. An examination of this shows that no point has been overlooked. We were pleased to notice that special attention had been devoted to the question of the strength of the front forks, the failure of which would have disastrous results. The B.S.A. Company have fully recognised this, and with the fork they have produced have no fear of its use with motors up to 2.5 horse-power. Another feature of note is that the hubs are not simply those used on cycles, but are made much stronger than usual.
191. The Kent Chain Cover. Here exhibited is a good idea for the protection of the upper surface of the chain. It is composed of a number of spring steel shields which fit one over each link; they clip firmly to the side plates and prevent dirt entering the chain bearings from the outside.
9 (ARCADE). Sutherland and Marcuson, Chandos Street, W.C., show some of their latest patterns of Umpire ignition cells for motorcycles, motorcars, etc., also various types of "Umpire" batteries and accessories for same. In conjunction with their batteries, this firm are now sending, out an improved form of variable resistance, which it is claimed supplies a long-felt want.
68. New Coventry Eagle Co, Coventry, have struck out on entirely new lines. A big loop frame with long wheel base is used, and the motor is placed well forward of the crank bracket in an upright position. The engine develops 2.25 h.p., has a one-piece cylinder and combustion head, and is fed through a spray carburetter. The silencing is intended to be effective, and certainly we have not yet seen so large an exhaust box on any other machine. The tank is capable of holding 1.5 gallons of petrol, and space is allowed for battery and oil, whilst the coil is carried by an aluminium bracket. The oil feed is by gravity, and is visible to the rider. Transmission is by a V-shaped three-ply belt. Ample brake power is provided, and both the front rim brake and back Bowden brake are operated from the one lever. The front forks are of the accepted girder pattern, and the mudguards are of ample width. The 2.25 h.p. engine sells at £50, and with a 1.75 h.p. engine at 45 guineas. The whole of the workmanship and design of the 1903 Coventry Eagle are distinctly creditable to the manufacturers, and we anticipate a very big demand for the machine. The new motorcycle trailer has a fine carriage-built body, with big storage room for touring purposes. An important feature of this trailer is that it is reversible, as our sketches show.
17 (ARCADE). Davis, Allen and Co, London, E.C. From a motor point of view, the interest at this stand centres on the Mitchell motor-bicycle, of which about half a dozen are staged. This machine, although an American production, is already so well known in this country as not to require a lengthy description. Suffice it to say, that the motor is of 2 h.p., and is located within the frame on the lower tube, driving rear wheel by a belt. Early in the year Rogers, an American expert, gave a demonstration of the speed capabilities of these machines on the track at the Crystal Palace, while in the recent anniversary run to Oxford of the A.C.G.B. I. a Mitchell gave a good account of itself notwithstanding the awful weather experienced.
120. W. R. McTaggart, Ltd., Dublin, show the FN motor-bicycle. This year the power has been increased to 2 horse-power, the weight of the machine even now being only 90lbs. The engine is placed vertically by means of an ingenious hoop in the lower diagonal of the frame, this enabling a longer belt, which is of the flat type. The well-known F.N. carburetter is, of course, fitted, the pattern remaining the same as last year. The advance sparking lever is provided with a series of nicks, which not only keeps the lever in position, but enables the driver to regulate the explosion to a nicety. A small compensation box is fitted, of clever construction, which maintains an equilibrium within it. A tube formed in the shape of the letter C is contained with its upper part outside the box, whilst the other is within it, thus any splash of oil into the box, which is connected at the bottom end to the crank chamber, is thrown back by the establishment of the equilibrium within and without. The make and break contact is the special design of this firm.
126. The Princeps Autocar Co., Northampton. The whole machine is of different design and construction to that lately made by this firm. The single cylinder is of 2 h.p., and is cast in one piece, with top radiators going to the centre to effect the greatest amount of cooling. The crank chamber is bolted to the frame by tee-shaped feet, having four bolts in each, thus making the frame and engine very rigid. A special form of combined float feed carburetter and regulator is fitted. An entire absence of wiring and levers render this machine extremely pleasing to the eye. A slight movement of the front lever serves to break the current.
The engine drives either by belting (Lincona) or by chain gear. This firm is also showing a twin engine of 4 h.p., fitted vertically in a similar manner to the single engine, with the advantage of its occupying no more space than the single type. It also shows an expanding form of a motor pulley of the V type. By pressing together of the sides of the V the belt is forced outwards, thus giving an increased speed of some 25 per cent. as a maximum; it also gives a free engine. In the chain-driven type a spring compensating wheel is used to take up the jar of starting and a friction clutch to give a free engine. The inlet valves are either fitted to work mechanically or automatically, according to the desire of the purchaser.
5-6 (ARCADE). Calverts Motor Cycle, Ltd., Kingsland Road, N.E., show various novelties and sundries connected th the motor industry. Two motorcycles are on view, both fitted with a Calvert engine of 2.25 horse-power, and weigh1ng 110 lbs. There may be seen special trembler coils for high speed engines, one giving forth a spark over 0.5in. long. Among the items to be seen are two-stroke petrol engines for motorcycles and cars, giving 3 horse-power at 1,200 revolutions per minute.
29 (ARCADE). James Dawson and Son Ltd., Lincoln, show specimens of their well-known "Lincona" belt for motorcycles. It is claimed for this belt that it does not stretch, slip or break, and preserves the bearings, and wears longer than any other. The company are showing the belt which has accomplished a 10,000 miles' record.
Other specialities on view are fasteners, pulleys, rims, and dressings, suitable for the fitting of "Lincona," the latter having the double purpose of keeping the band supple during wet weather and also of contracting the fibres of the leather, thereby taking up any slight stretch which may occur in working.
194. Joseph Lucas Ltd, Birmingham, This firm, with their "motoralities," are catering for the wants of motor-cyclists and motorists generally in an enterprising manner. Among the many lamps, from a huge headlight downwards, we note a new acetylene gas lamp specially designed for use on motor-bicycles.
The Wells-Lucas "Motoil" is shown in a variety of qualities, each adapted for its special purpose, the Motoil A for the engines of motor-bicycles being now made up in pint tins. The motor-cyclist may here take his choice between bells and horns of all sizes, while if touring inclined he will find all he wants in the way of luggage-carriers, tool-bags, etc.
Lifting jacks, spanners, tyre levers, grease injectors, motor tyre valves, inflators, etc., all find a place on Messrs. Lucas's stand. Among the oil cans we note a new pattern known as the "Forced Feed," specially designed for ensuring the oil being forced to the desired part.
73. A. W. Gamage and Co., Ltd., Holborn, are showing four Gamage motor-bicycles. The crank case of the engine constitutes part of the frame, to which it is bolted up. The engine is 2.125 horse-power, and has a very long stroke, namely, 80 mm. to a 68 mm. bore. The compression tap is opened by a twisting handle on left handlebar, whilst the one on the right hand advances and retards the ignition.
The carburetter is of the spray type, and requires no attention, consequently all levers are avoided. The drive is by a heavy three-ply belt, the driven pulley being fastened firmly to the rim. Pump lubrication is provided, whilst petrol capacity is a little less than a gallon. The machine sells at £40.
Of motorcycle and car accessories and spare parts, Messrs. Gamage have made a big feature during the past year, and from the wide and varied range which we saw on view on the stand in the Gallery we should imagine that no motor-cyclist need go farther than the Holborn emporium for any spare part or fitting that he might require. In clothing and outfitting, specially suited to the pastime, there is a wide selection, and it may be said with truth that the capacity of all pockets can be suited by Messrs. Gamage.
141. Perry and Co, Birmingham, show special parts for motor-bicycle frame building, including hubs, crank brackets, chains, fork crowns, free-wheels, spokes, nipples, lubricators, spanners, brake gear, and complete frames. Their trailing car fittings are worthy of special attention, and the general finish of all Messrs. Perry's work could not be excelled.
103. The James Cycle Co., Ltd., Birmingham, stage two motor-bicycles. The Model T has a 2 h.p. Minerva motor. An exceedingly strong fork crown and duplex forks are points that call for special notice.
The other model has a 2.5 h.p. Minerva motor fitted on to a special frame. This machine has a surface carburetter, extra powerful brake work, and the special spoking of the wheels call for attention. The finish of both machines is very handsome, the rims being nickelled, with green lacquered centres and edges.
28. Brown Bros. show is one bristling with interest for the motor-cyclist. Five Brown motor-bicycles are shown, including the old pattern 1.75 horse-power, and the new vertical motor of 2 horse-power. This has a spray carburetter, and very large tank capacity. Control is effected by two levers only. One machine has the 2 h.p. Minerva engine fitted. Car motors of various powers, and an 8 h.p. Brown car are shown. A motor-tricycle on De Dion lines finds a place, and in addition to these every motor fitting or accessory in practical use is shown, including coils, accumulators, standard parts of motors, lamps, jacks, motor clothing, lubricators, belting, electric wire, frame parts for motor-bicycles, lubricants, pumps, chains, gear wheels, etc.
93. New Hudson Cycle Co, Birmingham. Two very serviceable looking motor-bicycles are to be seen here, one fitted with a vertical 2 h.p. De Dion engine, embodying all the latest improvements, including their special silencer. The motor is clamped to the down tube, and in addition is supported behind from the bracket and seat tube. A special point about this motor is that it gives a much narrower tread than usual.
The other machine shown is fitted with the latest pattern 2 h.p. Minerva engine. Both machines have their special tubular stays to the front forks, spray carburetters, automatic lubrication, and are finished in the usual style for which this enterprising firm are noted. Price of either machine £45.
13V. Granoli and Lacoste, Boulevarde Magenta, Paris, have a special exhibit of electrical accessories for motor-bicycles and cars. These include coils, both of the trembler and non-trembler class, accumulators of various sizes, sparking-plugs, contact breakers, switch handles, electric wire, spark advance gear, etc. A special line, worth close inspection, is the firm's accumulator charging attachment for an electric light circuit. A visit to this stand will prove instructive and interesting to motorists generally.
23. The A. V. Motor Co., Birmingham. The A.V. motor-bicycle engine, in 1.75 size, is exhibited on a machine built of B.S.A. fittings; the engine clips on to the down tube of the bicycle frame a la Minerva; a spray carburetter is used, but perhaps the feature which catches the eye is the tank, which is made of polished oak, and decidedly adds to the appearance of the machine; petrol, oil, coil, accumulators, and spare tools are accommodated within this tank, which also contains the carburetter. A belt drive is used, the belt being of twisted raw hide.
75. The Monopole Cycle and Carriage Co., Coventry, are showing a couple of motorcycles, the engine of 2.25 h.p. being placed in a slanting position below the lower member of the frame. A spray carburetter is provided, and the drive is by a three-ply V-shaped belt. The tank is of large size, nearly filling the opening of the frame, giving room for oil, accumulators, and coil, and for a large supply of petrol. A Bowden exhaust lifter is used, and two brakes are provided, one being the New Departure coaster.
96. The Riley Cycle Co., Coventry, are showing a very powerful-looking motor-bicycle, fitted with an M.M.C. engine, 2.75 horse-power, which they are making their standard pattern. A special feature of this machine is a very strong triple head. A front band and a rear backpedalling brake are fitted. To this machine is attached a specially-built motor trailer, with double backbone, and a spring attachment.
Another machine, fitted with 2.5 Minerva, is also shown, with tandem attachment, which can be taken on and off in a few minutes, and is well worth inspection. This can be fitted to any of these machines at slight extra cost.
19 (ARCADE). Price's Patent Candle Co., Ltd., Battersea. No motor-cyclist needs reminding that this old-established concern has devoted special attention, under the direction of Mr. Veitch Wilson, to the question of the lubrication of motors and the various parts of motorcycles and cars that need attention of this kind. Price's motorine is now largely used, the B brand being that intended for use with small air-cooled motors; it is put up in quart tins. For the chains of motorcycles "Rangraphine" is specially recommended, acting not only as a lubricant, but as a protection against rust.
Messrs. Price publish a pamphlet on "Lubrication of Motor Vehicles and Cycles," and as this contains a vast amount of useful information those readers who have not yet got a copy would do well to write for one. Any motorcyclist who may meet with trouble in the matter of lubrication will always fired a sympathiser in Mr. Wilson, who will endeavour to rectify the trouble.
177-178. The Eadie Manufacturing Co., Redditch the Eadie fittings which have made such a name in cycle construction are well employed for making up a smart motorcycle. Only the frame pars, hubs, etc., are supplied, and they are adapted for use with the current makes of motors from 1.5 h.p. to 2.5 h.p. The front forks compel one's admiration for their sturdy and effective design. A very large D section tube tapers to a round section as the curve begins, and the fork is strengthened by taper tubes from the fork crown to top of head. The rear carriage is equally well designed, and the hubs, although obviously strong, are not unduly large or wide.
8. The Ideal Meyra Electric Co., London. This firm show specimens of their dry batteries, accumulators, and coils for motor ignition, also their motor signal lamp. This is an electric lamp, with powerful lens, and two coloured glass slides, red and green, either of which can be utilised; with the white light, the lamp can be used for examining the engine, gear, etc., in the dark; the light can be brought in contact with petrol fumes without the slightest danger. It is worked by a 6-volt accumulator, and runs for 36 hours on one charge; the accumulator slides in the box, and makes its own connection, the terminals of the accumulator coming in sliding contact with two brass strips inside the box, which is provided with a leather handle for carrying purposes. It is claimed for the F. and J. accumulators that they have a maximum capacity with a minimum weight.
179. Leatheries, Ltd., Birmingham. The two types of motor saddles staged by this firm are the British Pattisson Hygienic saddles and the Empire. The former is of very striking design, and takes our fancy as a really easy seat, four spiral springs of considerable height providing ample movement at the back; the seat is wide and may be contracted and expanded to the rider's requirements; the bifurcated top is, of course, especially advantageous for the motor-cyclist. The Empire is also of special design, especially as to its lower frame, which provides a strong base of neat appearance. Tool and accessory bags are shown in various sizes, a large one with several divisions attracting our special attention.
1. (MINOR HALL). The Starley Motor-bicycle. A new motor-bicycle appeared on the stand of the Houk Automobile Co, Ltd., late on Saturday. This was the Starley motor-bicycle for 1903. The frame is specially designed to take the engine, a tube runs from the top of head to a point on the strut, just above the bracket, and two twin tubes run from bottom of head to same point: the vertical engine is carried on an extension in front of the bracket. Each of the three triangles of the frame contains a tank, the forward one holding the oil, the tank in the main panel containing petrol, and a wooden box between strut and back wheel carries the coil and accumulators. Spray carburetter is fitted, warmed by hot air from the front of the cylinder. A drip-lubricator is fitted, the drip being variable by means of a lever on the oil tank. The low tension wires are contained in the frame tubes; this makes for neatness. A gear-case is fitted to this machine.
22. The London Autocar Co., London. A large assortment of motor parts and sundries, De Dion and Allard engines, lamps, etc.; also the L.A.C. set of rough castings, which are supplied to the trade for making up a 2 h.p. motor-bicycle engine. The London Autocar Company carry a stock of Ducellier motor lamps in all sizes, also sparking plugs, jacks; in fact, everything the heart of either novice or expert could desire.
102. Robinson and Price, Ltd., Chatham Street, Liverpool. Two specimens of the "R. and P." motor-bicycle are shown. These embody such new and special features that we deem the machine worthy of a full description. The bottom bracket and engine crank case are all cast in one piece, with socket lugs for the chain stays, tube from head, and strut of frame. The left side of the crank case is detachable by removing six bolts. The 2.125 h.p. engine is vertical; the silencer is of triangular shape, and is made of layers of aluminium and asbestos to prevent resonance. A spray carburetter is fitted, the air-regulating lever coming up through the tank. The rear portion of the tank is an oil reservoir; on turning a tap underneath, the oil drips through a sight-glass and through a large diameter copper-pipe to the crank case; the rate of drip can be regulated by a set screw. This is a very valuable and original feature. The tank is made in two pieces, recessed to fit the frame tubes. In the space between the two halves all the electric wires are concealed.
Wipe contact, with trembler on coil, is fitted. The first touch on the front wheel brake lever cuts off the current, further pressure putting on the brake. The throttle lever is on the handlebar, also the exhaust valve lift. The front forks, crown and steering tube are substantial; the steering head turns on 3/8in. bal's. V belt is used, the pulley being spoked into the rear rim with short spokes and nipples. The belt can be adjusted by draw-bolts at the back fork ends, and the chain by means of an eccentric in the bottom bracket.
24b. Maurice Gnapp, Dunstable, Beds., shows a cup drawer, which is of an adjustable form, capable of extracting the tightest cup in the bottom bracket of a cycle or motor. Also a useful form of lapping tool for making joints, extremely useful to the frame builder.
16 (ARCADE). The Petrol Motor Power Co., London, E.C. The novelty at this stand is an American motor-bicycle, known as the "Indian." The motor — of 2 actual horse-power — is built in the frame in such a way that it practically forms the seat tube of the frame. The "mixture" is furnished by a special float-feed carburetter. The machine is chain-driven, one chain connecting the motor with a chain wheel on a sleeve on the bottom bracket spindle, a second chain connecting this with the rear wheel. On the other side of the chain stays the usual chain and freewheel is provided for starting the motor. Apart from the handle switch, there are only two levers, one acting on the throttle and the other advancing and retarding the sparking. A feature of the latter is that when the spark is retarded to the utmost the exhaust valve is lifted.
7. Collier Twin Tyre Co. Ltd., London, W.C. The Collier pneumatic tyres are shown here in sections for all weights of motors. The system of fastening is the well-known "bolted on" method. A solid wire runs inside the foot of the tyre, inside a spiral coiled wire, which protects the actual tyre from being torn when the single wire is tightened. This is done by means of a number of threaded bolts, which come through the rim; these have eyelet holes in the heads, through which the wire passes, and nuts on the ends which project through the rim. A tool is provided to fit these nuts, after undoing which the tyre readily comes away from the rim. The tread is arched, rendering the tyre less liable to side slip, and making it clean, from a dust-throwing point of view. In the recent 4,000 miles tyre trials, promoted by the Automobile Club, the Collier scored 48 — the lowest number of marks for attention to tyres, one mark being deducted for every minute devoted to the tyres during the run, either for inflation, repairs, or any other cause. During the whole run, the set of Collier tyres suffered but one puncture. This was caused by a huge nail. The air-tubes out of the two front tyres are shown on the stand at the Show; these two tubes were never re-inflated from start to finish of the 4,000 miles. The covers are in the possession of the Automobile Club, so that they cannot be exhibited, but are still in perfect condition. Mr. W. G. Williams is in charge of the Collier stand.
