ABSTRACT:
An oscillating conveyor provided with an elongated low-profile frame having support wheels thereon. A plurality of conveyor rolls are rotatably supported on the frame at intervals therealong, which rolls define a horizontal support plane for a load to be conveyed. A drive device is connected to the frame to horizontally oscillate it back and forth through a stroke of predetermined length. A plurality of one-way holding members are mounted at closely spaced intervals along the length of the conveyor, which holding members permit one-way movement of loads along the conveyor but prevent backward movement thereof. When the frame is moved forwardly by the drive, the rolls remain substantially nonrotatable and hence move the loads forwardly through a predetermined step, during which forward movement the holding members are retracted to permit the loads to pass thereby. During the rearward stroke, the holding members engage the loads and prevent their rearward movement, whereby the rolls freely rotate beneath the load as the conveyor frame is retracted.
