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.

A crimping machine for serially advancing, feeding, and crimping electrical contacts of a type having a ferrule head portion and an elongated portion of smaller diameter than the head portion, the head portion defining upper and lower, peripherally extending support surfaces adjacent its periphery and facing the elongated portion, the center of gravity of the contacts lying between the lower support surface and the distal end of the elongated portion, the apparatus comprising: an annular hopper having a peripheral sidewall portion and a spiral pathway extending upwardly from the floor of the hopper to the sidewall, an outlet being formed through the sidewall adjacent and communicating with the spiral pathway; a first track structure, having first and second parallel rails spaced apart to engage mutually opposite portions of the lower support surfaces of the electrical contacts, the first track having a proximate end portion connected to the hopper adjacent the outlet and extending, substantially horizontally, tangentially from the outlet, and a second portion having a downward inclination which is insufficient to permit sliding movement of the contacts therealong absent vibratory movement of the track structure, the first track structure comprising a means for slideably engaging the lower, contact support surfaces on opposite sides of the contacts and for permitting movement therealong in response to vibration of the first track structure; vibratory means connected to the hopper for inducing vibratory movement of the hopper and of the first track structure for causing electrical contacts within the hopper to pass upwardly along the spiral pathway, through the hopper outlet, and along the horizontal and inclined portions of the first track structure with the lower support surfaces of the contacts seated upon the first and second parallel rails and their elongated portions extending substantially vertically downwardly between the first and second rails; a crimping mechanism, having means for crimping the ferrule head portions of the contacts onto electrical wires inserted into the head portions; feeding means for receiving the contacts and for sequentially feeding the electrical contacts into the crimping mechanism, the feeding means having an opening for receiving contacts to be fed to the crimping mechanism, and comprising a means for receiving the contacts in a substantially upright position and for imparting a longitudinal motion to the contacts as they are fed to the crimping mechanism; a second track structure extending substantially parallel to the inclined portion of the first track structure and extending partially over the first track structure, the second track structure comprising a means for receiving contacts from the first track structure, for engaging the upper support surfaces of the contacts, and for serially passing the contacts through the opening of the feeding means; and resonantly vibratory support means connected to the vibratory means, the feeding means and second track structure being mounted on the vibratory support means, the vibratory support means comprising means for supporting the second track structure in alignment with the first track structure, and for orienting the second track structure with an inclination insufficient to permit sliding motion therealong of the contacts, the vibratory support means comprising means for inducing vibration of the second track structure for enhancing movement of the contacts therealong, the first and second track structures having respective distal end portions, in vertical alignment, which comprise means for transferring vibratory motion from the first to the second track structures through any electrical contacts which are vertically aligned with both the first and second track structures.
