Messrs. Aveling & Porter, of Rochester, England, have for many years taken a leading position in the manufacture of traction engines. Fig. 2 shows one of their compound road locomotives, specially intended for continuous hauling work on the roads. The high and low pressure cylinders are placed side by side at the smoke-box end of the boiler, the pistons and connecting rods actuating a double-throw crankshaft.
In order to place the slide valves close to the top of the cylinder, the valve rods are arranged on an incline. Some of the gearing is placed inside the box brackets between the bearings. The side plates of the boiler are carried upward, and at the top a strong casting is secured. In this casting are combined the bearings for the crankshaft and the two countershafts, forming a substantial arrangement for keeping the spur gearing in proper working condition.
A worm barrel is provided for the steering chains to coil on, preventing the chains from mounting, and for taking up the slack. The feed pump is fixed on the boiler barrel, the suction pipe leading direct into the pipe which connects the two tanks as shown. The engine parts are boxed in, and the gearing is covered. The equipment is complete, and care has been expended on the design and construction of this engine so as to render it in every way worthy of the name it bears. Such engines leave little to be desired on the scores of simplicity, strength, durability and economy in working. |
