Abstract
Disclosed is a mechanism for driving the paper delivery rollers in an elevator of an elevator-type sorter. The elevator is adapted to move through a passage that extends between the conveyor belt and the inner ends of a plurality of shelves. Paper sheets are delivered to the shelves through a deflecting path defined by the internal framework of the elevator. The paper sheets are fed onto the shelf by paper delivery rollers which are driven by a series of gears and a toothed belt mounted on the elevator. The gears are, in turn, driven by a rubber "tumbling roller" which is mounted in a pivotable bracket. This bracket is biased by a spring to bring the tumbling roller into contact with the conveyor belt so that its movement imparts a rotational motion to the tumbling roller.
