Abstract: An accumulating conveyor system has an improved carrier assembly and delatching dog therefor which allows the carrier assembly to be orientated along a carrier path in any angle relative to the ground. On a three rail conveyor system, a pallet beam is slidingly connected to the two outer rails. A beaver tail carrier is centrally located on and connected to the pallet beam. The center rail carries a moveable chain having delatching dogs attached thereon at predetermined locations. The delatching dogs are releasably connectable to the beaver tail carrier and function to maintain connection with the beaver tail carrier in any angle along the conveyor path relative to the ground by means of a spring mechanism until an encounter with another beaver tail carrier.
