ABSTRACT:
A fastener driving apparatus is disclosed which comprises a vibrating feed hopper, a fastener feed assembly for receiving the fasteners from the hopper and serially delivering the fasteners to a discharge tube which leads to an automatic screwdriver. The fastener feed assembly comprises a body member which mounts a slide for transverse sliding movement between a first position wherein the fastener is received in a notch in the slide, and a second position where the fastener is delivered to a discharge opening which leads to the discharge tube and to the screwdriver. A first air line system is provided for moving the slide toward the first or fastener receiving position, and for concurrently injecting air into the discharge opening to move a fastener previously positioned in the tube to the screwdriver. A second air line is provided for directing a stream of air into contact with the fastener at the second position so as to positively move the fastener into the discharge opening.
