ABSTRACT:
An automatic fastener feeding and driving apparatus is disclosed which includes a vibrating feed hopper, and a fastener feed assembly for receiving the fasteners from the hopper and serially delivering the fasteners to a delivery line which leads to an automatic hand held driver. The fastener feed assembly comprises a body member having a slide for transverse sliding movement between a first position wherein a 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 line and to the driver. The body member and the slide include an internal air line system by which air is delivered into the lower portion of the notch of the slide and into the discharge opening, only after the slide has essentially reached its discharge position. This timing of the delivered air avoids undue pressurization and turbulence in the discharge line prior to the entry of the fastener, which can interfere with the gravity drop of the fastener into the line. A novel control system for operating the feed slide is also disclosed, which includes a four way air valve which is controlled by the operation of the trigger of the driver.
