摘要

Improvements in the guide body and nail feed mechanism of a nail driving tool, using wire collated nails, to eliminate the formation of loose pieces of collating wire and the trapping thereof under the heads of driven nails to form flags. The tool has a driver, a magazine containing a coil of nails joined together in spaced relationship by collating wires welded to each nail, a guide body providing a drive track for the driver and the nails, and a feed pawl which advances and retracts in guideways in the guide body and has fingers engaging nails of the coil to locate the forwardmost nail thereof in the drive track. As the forwardmost nail of the coil is driven into a workpiece the collating wires break near the forwardmost nail leaving forwardly extending wire segments on the next succeeding nail. The drive track is provided with windows positioned to receive the wire segments of the forwardmost nail and bend them upwardly along the nail shank as the nail is driven. The feed pawl is provided with wide feed fingers to support the wire segments of the second nail of the coil, tending to assure breakage of the wires near the forwardmost nail and orienting the segments for receipt in the drive track windows. The pawl and the drive track are configured to prevent breakage or nicking of the segments of the second nail by the head of the forwardmost nail. The nails of the coil are spaced to assure wire segments of sufficient length.
