ACCUMULATING PALLET CHAIN-DOG CONVEYOR AND METHOD OF CONVEYING PALLETS ABSTRACT OF THE DISCLOSURE An accumulating pallet chain-dog conveyor has spring-biased roller assemblies attached to the pallet underside for frictionally engaging dogs and spacers which are connected to an endless chain. The roller assemblies include rotatable rollers having a plurality of flats for engaging the surfaces of the dogs and spacers. In operation, the pallets are propelled by the dogs which are engaged by the spring-biased rollers. The conveyor includes a pallet stop which halts the forward movement of the pallet at a predetermined position. When the forward movement of the pallet is stopped, the opposed rollers rotate the distance of one flat whereby the dog passes between the rollers in sliding, frictional engagement therewith. Thus the pallet stops and the endless chain with its attached dogs and spacers continues to move. After the dog passes from between the opposed rollers, the rollers slidingly, frictionally engage a spacer which also passes between the rollers. This sliding, frictional engagement with the dogs and the spacers during the time in which the pallet is stationary due to its engagement with the pallet stop prevents rearward and lateral movement of the pallet. In another aspect, the conveyor includes a pallet-propelling sprocket in synchronous motion with the endless chain and a plurality of sprocket- receiving pins mounted on the underside of the pallet. The conveyor includes a drive course and return course linked by turn courses. As a pallet reaches the end of the drive course or the end of the return course, the pallet-driving sprocket engages the pins whereby the pallet is carried through the turn course.
