ABSTRACT:
A level gravity conveyor provides a plurality of individual load-engaging support pads aligned longitudinally along the conveyor. The pads are movably supported on runway segments which extend longitudinally. Each runway segment defines an upper raceway surface which movably supports the pad, which upper surface in the preferred embodiment is defined by a plurality of support rollers. The runway segments are alternately raised and lowered so that, when in a raised position, the upper surfaces slope downward in the forward direction. The pads engage and vertically lift the loads when the runway segments are in the raised position, whereby the weight of the loads causes the pads to move downwardly by gravity along the inclined upper surfaces to forwardly advance the loads through a small distance. When the runway segments are lowered so that the pads disengage the loads, the upper raceway surfaces slope downwardly in the upstream direction to cause gravity-induced return movement of the pads to their original upstream positions.
