. Electric railway journal . ond-hand material, thegeneral design being shown in the photographs. Theinside base flange of the 9-in rails forms a track onwhich the pusher wheels run.

Two parallel tracks are located along the dump, thecar to be unloaded being placed on the track nearestthe edge of the bank and the unloader being placed onthe other track opposite the car. The car shown has February 15, 1919 Electric Railway Journal 325 a cab in the middle. Other cars have a cab at eachend, and either type can be used. To unload a car theside boards are dropped and the unloader boom isswung across the car in a horizontal position withthe pusher at the crane end. The pusher is movedforward over the edge of the car floor and the boomis then lowered until the plate rests firmly on thefloor. The pusher is then moved forward, pushingoff one-sixth of the load or nearly 4 The crane. LEVELING OFF THE EARTH AT THE EDGE OF THE DUMP is then moved to a new position. Six movements usuallyunload a 22-yd. car in about fifteen minutes. When five or six cars are unloaded each day, the caioperator and two helpers handle the car to and fromthe construction job and also do the unloading. Ifmore cars are handled it is necessary for the operatorto stay at the dump all day. The earth from the car does not immediately rolldown the dump bank, as the track is usually too farfrom the edge. It is forced over the bank by loweringthe boom after the car has been removed and movingthe pusher forward as shown. As the track is 300ft. long it is necessary to do this only when earth hasbeen dumped all along the track, which may requireseveral days. The dump can be used several monthswithout moving the track nearer the bank, as the makes it possible to use the dump with the cartrack 20 ft. from the edge of the bank, thus also re-ducing track moving expe
