  • Patent number: 4510826
    Abstract: An attachment for a screwgun includes a hollow barrel and a hollow sleeve which is adapted for sliding movement with respect to the barrel. The sleeve and barrel are biased apart by a spring. A drive rod which extends through the hollow portions of the sleeve and barrel coacts with a screwgun to transfer the driving force of the screwgun to a fastener. A feed tube is attached to the barrel by a hinge which extends through a slot in the sleeve. An outlet end of the feed tube is in communication with a portal in the barrel through which a fastener may be inserted into the barrel when the feed tube is in a first position. In a second feed tube position, the outlet end of the feed tube and the portal of the barrel are spaced from each other.
