  • Fastener magazine and guide device
    Patent number: 4898316
    Abstract: A fastener magazine and guide device for use with a moveable fastening tool. The fastener magazine contains a coil of fasteners and is mounted in a fixed position in close proximity to the fastening tool. A guide is attached at its one end to the fastening tool by an angular tongue, while its other end is mounted near the fastener magazine such that the guide can move with the tool but does not transmit movement to the fastener magazine. The fastener magazine is mounted on an angle to allow for smooth feeding of the fasteners to the tool.
