ABSTRACT:
A workpiece having an enlarged head and a stem extending therefrom is conveyed in a gravity chute while supported vertically in a ring-shaped pallet with the head supported on the top side of the pallet and the stem extending downwardly through the pallet. The pallet and workpiece are then directed through a downwardly curved orienting chute and come to rest on stop surfaces wherein the workpiece is inclined downwardly, its head foremost, and the axis of the pallet is horizontal. In this position the workpiece is centered with respect to the aperture in the pallet so that the workpiece slides downwardly out of the pallet through an unloading chute. At the lower end of the unloading chute the workpiece falls through a contoured aperture into a downwardly inclined delivery chute which extends in the direction opposite to the unloading chute.
