63,255-010 An improved chain conveyor and pallet structure are disclosed in which the pallet contacts the middle link of the three-link chains typically employed in chain conveyors, and is supported upon the outer and inner links of the chain. The distance between the pallet contact members and the support surfaces is increased such that the pallet may be removed from the chain conveyor for repair or placement on a second conveyor. In another feature of the present invention, the pallet is supported on the center link on both its upper and lower run, allowing the use of heavier sturdier pallets. At least some of the rollers in the middle links are preferably of a greater diameter than the rollers on the inner or outer links reducing the Starr between the link and the pallet, and increasing the life of both members. The present invention also discloses a speed bar placed below the three link chain to engage and rotate the center link increasing the speed that the pallet is moved at, and providing for a localized increased speed for the pallet.
