Abstract
A lift and carry accumulating conveyor is disclosed having a frame and a pair of elongated stationary rails attached to the frame such that the stationary rails are spaced apart and parallel to each other. A transfer rail assembly having a pair of elongated transfer rails is positioned in between the stationary rails and are movable relative to the stationary rails between both a raised and a lower position as well as between a forward and a retracted position. A pair of longitudinally spaced drive arm assemblies are pivotally disposed between the frame and a lower end of the transfer rail assembly. The upper end of each drive arm assembly abuts against the lower end of the transfer rail assembly so that, as the driver arm assembly is pivoted between a lower and an upper position, the drive arm assemblies simultaneously move the transfer rail assembly between its lower and raised positions. A single elongated link extends between the drive arm assemblies which ensures that the drive arm assemblies move in unison with each other.
