Fig. 3328.

[Fig. 3328] represents an American passenger locomotive with a steam reversing gear, or in other words, a reversing gear that is operated by steam.

The link motion is substantially the same as that shown in [Fig. 3326] for a freight locomotive, the eccentric rods in this case being straight, as there is no wheel axle in the way.

The injector for feeding the boiler is the same as that shown on the freight locomotive.

The ash pan is provided with two dampers, one at each end, and the front one is operated by the bell crank a c.

The sand boxes are here fastened to the frame, both sand valves being operated by the lever m, which at its lower end connects to a rod, u, which at its back end connects to an arm, p, on a shaft that extends across the fire box and connects to a rod corresponding to rod u, but situated on the other side of the engine and connecting with the other sand valve.

The steam pump for the automatic air brake is on the other side of the engine, and the air reservoirs, of which there are two, are horizontal and situated beneath the front end of the boiler. The air pipe to the triple valve here connects to the front pipe of the three beneath the triple valve, the middle pipe being that which is open to the atmosphere, which is the usual construction. The engine brake receives its air from a pipe on the other side of the engine which feeds the pipes g, v, for the brake cylinder shown in the figure. When the engine is running backwards, the train brakes are operated through the medium of the “pipe to air brake and to front end of engine” which is shown broken off.
