Patent number: 4021902Abstract: A coiled vibrating feeder is provided for individually feeding a plurality of workpieces. An elongated enclosed tubular passageway is formed, preferably by coiling an elongate tube into a bundle having a plurality of generally concentric coil turns and including a charging end for receiving the workpieces to be fed and a discharging end. The coils are circumferentially vibrated about the axis of the bundle by alternating strong forward pulses and weaker return pulses so that the workpieces progress therethrough from the charging to the discharging end. A bonding material such as a plastic material or the like substantially engages all of the coils, thus increasing the rigidity of the bundle of coils, thereby increasing the efficiency of transferring the forces of the vibrations from the vibrator to the coils and hence to the workpieces to more effectively move the latter.Type: GrantFiled: June 4, 1976Date of Patent: May 10, 1977Inventor: Max G.
