<p>A releasing means and dog means for a power and free type of conveyor is described. The releasing means 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 means (12). Extending means, 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.</p> |
