Abstract
The barrel assembly for attachment to a standard driving tool includes a sleeve adapted for attachment to the tool, a barrel retractably mounted in the sleeve and a bushing positioned within the sleeve and extending into a barrel bore. The barrel includes aligned entry and exit trackways to accommodate a strip containing fasteners and the bushing is adapted to position the fastener within the bore of the barrel in a first position and then in a second position engage the strip so as to clamp it in place as the driver disengages the fastener therefrom. A carriage assembly can be positioned within the end of the barrel so as to form an internal restrictive bore for the fastener in a first position and an enlarged bore in a second position so as to permit the fastener to pass therethrough.
