ABSTRACT:
A releasing device and dog member for a power and free type of conveyor is described. The releasing device includes a rod (105, 205) which is linearly moveable upon engaging a stop or a truck (17) with a buttress plate (105a, 205a) on the rod to disengage a retaining plate (100a, 200a) on a pivotal dog (100, 200), thereby allowing the dog to pivot away from a pusher member (12). An extending device, such as spring (108) or camming member (209), urges the rod to an extended position when the stop or forward truck is removed from engagement with the buttress plate.
