Abstract: A pusher mechanism supported on a framework for deflecting objects from a conveyor has a retractable pusher which is mounted for linear movement transversely across the conveyor. A paddle is pivotably attached at its midportion to an outer end of the pusher. A movable link is secured between the framework and an end of the paddle. Due to these paddle connections, controlled linear movement of the pusher will cause the paddle to articulate on the pusher from a rest position to an operating position at which an object is deflected from the conveyor and back to the rest position.

Abstract: A telescopic drive line includes an inner square drive shaft and an outer drive tube having a square bore at one end. A liner in the bore has a Teflon fabric inner surface providing a low-friction bearing with a low breakaway force. Radial force applied to the liner secures it axially in this bore so that only the simplest means of endwise securement is required.
