Abstract

In a package sortation conveyor comprising an endless apron supported for movement on a frame defining a main line and one or more side outlets therefrom, and a plurality of pusher elements mounted for sliding movement on the apron from one side thereof to the other to push a package through one of the side outlets, each pusher element has a guide pin depending therefrom and an anti-friction bearing on the upper part of the guide pin for cooperation with a switching mechanism and a camming bar in such manner that when a pusher element is diverted from its rest position at one side of the apron, the bearing thereon will engage the camming bar during the balance of its travel across the apron. In addition, special guide members are provided for preventing any incompletely diverted pusher element from jamming against a stationary part of the conveyor and for preventing any pusher element from jamming against a package which has been held against forward movement on the apron.
