Apparatus for Supplying Water to Tenders While in Motion

LONDON AND NORTH-WESTERN RAILWAY COMPANY, Works at Crewe.

1269. Locomotive and tender.

1270. Apparatus for supplying water to tenders whilst in motion.

1271. Wrought iron chair. Duplex safety valve.

LOCOMOTIVE ENGINE. - Designed and built by Mr. Ramsbottom, Locomotive Superintendent, Crewe, and exhibited as a specimen of a first-class passenger engine. It is fitted with patent pistons, duplex safety valves and lubricators, and is adapted for burning coal with great economy. An engine of this class ran the American express on the 7th January 1862, a distance of 130.5 miles without stopping, at an average speed of 54 miles per hour. The tender attached is fitted with Mr. Ramsbottom's apparatus for taking up water whilst running.

APPARATUS FOR SUPPLYING WATER TO TENDERS WHILST IN MOTION. - This is the invention of Mr. Ramsbottom, Locomotive Superintendent, Crewe. The plan has been in daily operation on the Chester and Holyhead Railway since it was first adopted in the winter of 1859-60. By it various quantities of water, from 1,200 gallons downwards, can be picked up at speeds ranging from 22 to 50 miles or upwards per hour. In the running of the Irish mails, the arrangement has the effect of reducing the dead weight of the tender about 6 tons, equal to the weight of a loaded carriage.

WROUGHT IRON CHAIR. - Invented by Mr. Ramsbottom, Locomotive Superintendent, Crewe. The above are made from rolled bars of suitable section, and are cut off whilst hot to the requisite breadth. The rails are held by the sides and shoulders, and are not in contact with the bottom of the chair. The lower head of the rail is consequently not indented, so that when inverted the second head is as good as the first. Both chairs and keys are of wrought iron, so that they do not get loose nor break. The chair has also a very broad base in proportion to its weight, and is therefore not so easily crushed into the sleeper. It is, moreover, applicable to a variety of sections of rails, by merely altering the form of the keys or filling-in pieces.

DUPLEX SAFETY VALVE. - This arrangement of safety valve, the invention of Mr. Ramsbottom, Crewe Works, is intended to prevent the boiler to which it is applied from being subjected to any pressure in excess of that to which it is adjusted. If any weight is put upon the lever, it has the effect of reducing the pressure, instead of increasing it, as in the ordinary arrangement. It requires no spring balance, and gives a much wider opening for a given excess of pressure, than the ordinary valve.
