Knight's American mechanical dictionary : a description of tools, instruments, machines, processes and engineering, history of inventions, general technological vocabulary ; and digest of mechanical appliances in science and the arts . the heating surface of the lire-box153 square feet. D is an express-engine designed by Crampton forthe .same road. It is adapted for the usual gage. For details of English locomotives, which differconsiderably in construction from those used in theUnited States, the reader is referred to Engineering. The engines employed on the Irish mail-trains be-tween London and Holyhead weigh 27 tons ; thetenders 17 tons, carrying 2 tons of .coke and 1,500gallons of water. The cylinders are of 16 inches diameter and 24-inch stroke. The apparatus forfeeding the fuel also provides for the comljustion ofthe smoke. The engine is sui)plied with water whilerunning, from a trough beneath the rails, from whichthe water is scooped up by the tank. The cost of alocomotive of this description is nearly £3,000. Itis said that one of them has been known to run 130miles in 144 minutes, Fauldings locomotive (English) is designed toavoid the inertia of its working It has an Fig. A, Stfphrn^nn^s Rocke! (1829).

Thecrank-axles are at right angles with each other, sothat each wheel is driven alternately. The cylindersare carried on a frame supported by the journals ofthe driving-wheels, so as not to be affected by themotion of the springs.
