Title: Automatic fastening system

Abstract: An automatic fastener feed system provides a nut, bolt or other fastener to a movable drive tool such that the fastener is automatically engaged with a drive member on the drive tool and subsequently driven onto a corresponding fastener on a work piece. The feed system includes a fastener acceptor which is adapted for connection to a parts feeder via a supply line. The parts feeder provides the fasteners to the fastener acceptor, which at least temporarily retains the fastener in a position for engagement with the drive member. As the drive member rotates and moves through the fastener acceptor toward a mating fastener on a work piece, the fastener within the fastener acceptor is automatically aligned and engaged with the mating fastener as the drive member is rotatably driven by the drive tool. Continued operation of the drive member causes the fastener acceptor to release the fastener, thereby allowing the fastener to be driven completely onto the mating fastener on the work piece.
