<p>A fastener driving tool (1) capable of locating a preformed hole in a first workpiece, aligning the drive track (5a) of the tool (1) with the hole, and thereafter driving a fastener, such as a nail (26), through the hole and into a second workpiece to attach the first workpiece to the second workpiece. The tool (1) has a magazine (4) comprising an outer portion (18) affixed to the tool (1) and its drive track (5a) containing guide body (5), and an inner portion (19) containing a strip of nails (25) and pivoted at its rearward end to the rearward end of the outer magazine portion (18). The inner magazine portion (19) is pivotable within the outer magazine portion (18) between a first position wherein the forwardmost nail (26a) of the strip (25) extends well beyond the nose (5c) of the guide body (5) serving as a probe to locate and enter the workpiece hole, and a second position wherein the forwardmost nail (26a) of the strip (25) is still engaged in the workpiece hole and is properly aligned in the drive track (5a) to be driven by the tool driver (8) through the first workpiece hole and into the second workpiece. The inner magazine (19) is operatively connected to a safety trip (6) which is shiftable between a first, disabling position when the inner magazine portion (19) is in its first position and a second enabling position allowing the tool (1) to be actuated when the inner magazine (19) is in its second position. The inner magazine portion (19) and the safety trip (6) are biased to their first positions.</p> |
