ABSTRACT:
A power-driven hand-held fastener driving machine includes a housing including a reciprocally movable blade, a magazine for carrying a strip of fasteners such as staples, and a guide assembly composed of first and second guides defining a drive track therebetween. A safety device is actuatable in response to being pressed against a workpiece for depressing a switch means to move the blade for driving fasteners one at a time into the workpiece. The safety device is composed of first and second separate members, the first member being engageable with the switch means and the second member being angularly movable into and out of engagement with the first member and engageable with the workpiece. When the second member is out of engagement with the first member, the first member will not actuate the switch means to prevent accidental driving of the blade. A guide locking device keeps the first and second guides together, and, when unlocked, allows the second guide to be angularly moved away from the first guide to open the drive track.
