Abstract
An endless accumulating conveyor has upper and lower guide rails for supporting pallets. An endless roller chain has an upper run extending along the upper guide rails and a lower run extending along the lower guide rails. A dogging device on each pallet is engageable between the rollers of the chain to move the pallet with the chain along the upper and lower runs. A friction clutch for the dogging device of each pallet causes the dogging device to release and slip past the rollers of the chain when the pallet encounters a predetermined resistance to movement, as when it is desired to accumulate pallets. Mechanism is provided for positively propelling each pallet over the curved section at both ends of the conveyor from one run to the other without slipping.
