ABSTRACT:
Apparatus for serially feeding and crimping a plurality of electrical contacts of the type having an open-ended, ferrule head portion adapted to receive an uninsulated end of an electrical wire and to be crimped into electrically conductive contact therewith. The contacts are serially discharged from an annular hopper and caused to attain an upright position. First and second tracks, mutually aligned and vertically spaced one from the other, are provided for transporting the electrical contacts, while in the upright position, from the hopper to a mechanism for feeding the contacts into a crimping chamber. The tracks have a downward inclination from the hopper which is insufficient to permit sliding movement of the contacts absent vibratory movement of the tracks, which movement is derived from a vibratory device connected to the hopper. Vibration transfer from the first to the second track is effected through the electrical contacts and, in a preferred embodiment, through a vibratory support unit connected to the second track and to the vibrating device. In a preferred embodiment, the first track, connected to the hopper, extends beneath the second track for increasing the kinetic energy of electrical contacts which transfer vibratory movement from the first to the second track and for preventing passage of any longitudinally interconnected contacts from the first to the second track.
