Machine tools.

Prize Medal awarded at the Exhibition of 1851; Prize Medal awarded at the Paris Universal Exposition, 1855; Prize Medal awarded from the Society of Arts, 1855.

Fig. 1. MUIR'S SELF-ACTING 12-1N. CENTRE DUPLEX LATHE for sliding and screw cutting. Double-geared headstocks, with wrought-iron steeled mandrel, running in hardened cast-steel conical bearings, guide screw full length of bed, with patent self-acting screw bearers, bed 25 ft. long, with patent duplex slide, carriages with clamp nuts by eccentric, rack and pinion for quick return by hand, the slide rests have two releasing motions for drawing back to tool slides. There is also a new reversing motion for changing from right to left hand, screw cutting, without changing the wheels, of which there are 22. Clements and common drivers, face-plate, backstay, etc. etc. This lathe is specially adapted for cutting screws expeditiously, and for sliding shafting at once going over.

Fig. 2. MUIR'S PATENT 7-IN. CENTRE DOUBLE-GEARED LATHE, for sliding and screw-cutting, wrought-iron steeled mandrel running in hardened cast-steel conical bearings, guide screw full length of bed, which is 6 ft. long, reversing motion to slide and cut screws right or left hand without changing the wheels, of which there are 22, eccentric to lock the cone pulley, eccentric back-shaft, the slide carriage has clamp nut by eccentric, rack and pinion for quick return by hand, releasing motion to tool slide, elements and common drivers, 14-in. face plate, centre chuck backstay, hand rest, etc.

Fig. 3. MUIR'S PATENT 8-IN. FOOT LATHE, with 2 treadles, for screw cutting. Designed particularly for use on board steam vessels, for repairs afloat, or for the colonies, where labour is cheap, as with an assistant a workman will be able to do as much work as with a steam-power lathe of the same capacity.

The same lathe is also fitted with four treadles for India, the wages of the natives being so low, it will in many places be found more economical than steam-power.

Fig. 4. POWERFUL SELF-ACTING RADIAL DRILLING MACHINE, with vertical elevating slide radial arm, movable through an arc of 190°, to drill holes up to 10 in. diameter.

This machine is particularly adapted for drilling ends of boiler plates, large cylinders, and all work of a massive character, as it will take in an object 9 ft. high; all holes within range of the machine can be drilled without removing the object,

Fig. 5. SELF-ACTING VERTICAL DOUBLE-GEARED DRILLING MACHINE, with circular revolving table on a radial bracket, which can be raised or lowered on a vertical slide by means of a worm wheel, so that when the work is once fixed a hole can be drilled on any part without moving it.

This drill is provided with a hardened steel locknut, which entirely prevents any backlash in the spindle.

Fig. 6. SELF-ACTING UNIVERSAL SHAPING MACHINE, with a variable stroke from 0.5 in. up to 6 in. Will plane an object 2 ft. long, circular work of 12 in. diameter, and can be changed to plane round, hollow, or flat surfaces, without refixing the article operated upon.

Fig. 7. SELF-ACTING SLOTTING AND SHAPING MACHINE, with a variable stroke up to 6 in. Will take in a wheel 3 ft. diameter, self-acting transverse and circular motions.

Fig. 8. SMALL PLANING MACHINE, worked by hand or power, with crank movement and elliptical wheels for producing uniform motion in cutting, and treble speed in return of the table.

Fig. 9. MUIR'S PATENT GRINDSTONE APPARATUS for grinding edge tools. The stones are regulated by means of a right and left hand screw, and a lateral motion is given to one of them by means of a cam, thus enabling the workmen to grind their tools with a degree of accuracy hitherto impossible, and also doing away with the great dust arising from turning-down stones, so injurious to the bearings of all machinery.

A prize medal was awarded for this machine at the Paris Exposition, 1855, and also by the Society of Arts during the same year.

Fig. 10. A COMPLETE SET OF IMPROVED SCREWING PACKLE.

The dies are made so that one will serve as a guide, and the other as a cutter, which can be sharpened on a grindstone. The taps are fluted in a superior form for cutting; the cutting edge is a radial line through section of tap, which is found by experience to take about one-third less power than taps that have hitherto been in use; they are made to standard gauges. The angle of the thread is 55 degrees for all diameters, rounded both at the top and bottom.

Fig. 12. MUIR'S IMPROVED COPYING PRESS, without stand. These presses are designed on the elliptic and screw principle; in quarto, foolscap, and folio sizes.
