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