Abstract: Ballast cleaner mechanism carried by a railroad car along a railroad track in which an infeed conveyor supported on the car receives the dirty ballast and divides it into a multiplicity of substantially equal streams of ballast which are discharged laterally on opposite sides of the conveyor at predetermined locations along its length onto a similar plurality of shaker screens. The clean ballast from these screens is discharged onto a clean ballast conveyor, disposed beneath and generally parallel to the infeed conveyor for delivery to a suitable discharge point, while dirt conveyors disposed on opposite sides of and parallel to the clean ballast conveyor are located beneath the respective screens for reception and removal of the dirt sifted through the screens from the dirty ballast.
