  • Patent number: 4370819
    Abstract: An apparatus for depositing and spreading ballast between and exteriorly of railroad rails and cross ties. A hand pushed or motor driven ballast spreader has a ballast hopper supported by a frame mounted on wheels engageable with the railroad rails. The hopper has an open top and an open bottom with converging lower walls. Ballast may be deposited between the rails through a door mounted horizontally beneath the frame and through a slot in a fixed chute. Ballast may also be deposited exteriorly of the heads of the cross ties by passing through the fixed chute and through a pivotally movable chute which is pivotally mounted near each lateral end of the fixed chute. Resiliently mounted blades clear excess ballast from the ties between the rails and from the heads of the ties exteriorly of the rails.
