Abstract: An endless loop accumulating conveyor of the over/under type adapted to slidably support pallets and to frictionally transport them over both the upper and lower conveyor runs. The conveyor including a coupling to couple the pallet to the endless loop including a pin inserted into the endless loop to couple the pallet to the endless loop when the pallet is in the proximity of the curvilinear ends of the conveyor.

Abstract: A roller assembly for use with a conveyor for transporting a workpiece wherein the drive force applied by the roller is adjustable independent of the force generated by placing a workpiece on the roller. The roller includes an inner sleeve secured to a drive shaft of the conveyor. A roller is disposed about the inner sleeve and is frictionally fit along an interface between the roller and an inner sleeve such that when a weight is placed upon the roller, the frictional force occurring between the interface between the roller and sleeve causes the rotating inner sleeve to impart motion to the roller thus moving the workpiece. The roller includes a connection to the inner sleeve such that the coupling or frictional force between the roller and the inner sleeve is independently variable of any force generated by placing a workpiece on the roller.

Abstract: A conveyor for transporting a workpiece from a first position to a second position along a curved path. The conveyor includes side members including a plurality of individual members arranged adjacent one another and allowing for such that individual members may move in a longitudinal direction relative to adjacent individual members to change the overall length of the side member. The side members are interconnected through use of slots and fasteners such that the slots in adjacent individual members are offset to allow for longitudinal adjustment between the adjacent members. Such adjustment results in an adjustable flexible conveyor enabling the conveyor to be adjustable in either direction along a particular curved path or configuration.
