ABSTRACT:
A power and free conveyor has a stop lug on the carrier body adapted to abut a stop member movable into the path of the carrier along the conveyor track to arrest movement of the carrier, the stop member serving to disengage the driving dog from the power chain prior to abutting the stop lug. The stop lug is spaced rearwardly of the driving dog a distance exceeding rebound of the carrier whereby accidental re-engagement of the driving dog with the power chain is avoided. The stop lug is positioned to engage the power chain pusher lug on a decline in the conveyor system should the hold-back dog fail to do so, thereby preventing a runaway.
