Abstract
A stop mechanism for detaching a conveyor trolley from a drive system which normally drives the trolley along a conveyor track. A ramp can be moved into the path of a trolley dog so that the trolley dog moves upwardly along an inclined ramp surface to disengage the trolley dog from a drive dog carried by a driven chain of the conveyor system. The actuating mechanism for the ramp includes a pivotal cam plate actuated by a power cylinder. A cam slot in the cam plate receives a cam roller connected with a guide link which moves in a vertical guide slot. The guide link is connected with the ramp to move it up and down under the control of the actuating cylinder.
