ABSTRACT:
Randomly oriented screws are deposited onto two horizontally spaced endless belts and are advanced toward a track located adjacent the ends of the upper runs of the belts. As the screws are advanced, the belts are vibrated vertically to shake the screws to properly oriented positions in which the screws hang by their necks from the belts with their shanks located between the belts. Vibration of the belts is effected by means of lugs formed on the inner sides of the belts and operable to flex the belts upwardly and downwardly as the lugs pass across pulleys which support and guide the belts. Also disclosed is a clearing wheel for flinging any improperly oriented fasteners from the track, the clearing wheel being constructed from a series of face-to-face discs made of comparatively soft urethane or the like.
