Abstract:
A screwdriver assembly to drive threaded fasteners collated together in a strip spaced in parallel relation from each other, the screwdriver comprising:a cylindrical guideway to receive a fastener coaxially therein,a fastener-and-strip entranceway opening generally radially into the guideway on a first side thereof,a strip exitway opening generally radially out of the guideway on a second side thereof opposite the entranceway,the guideway, the entranceway and the exitway juxtapositioned to permit fasteners collated in a strip spaced in parallel relation from each other to be successively advanced through the entranceway radially into the guideway to locate each successive fastener coaxially within the guideway with portions of the strip from which fasteners have been driven extending from the guideway via the exitway,an elongate, rotatable driver shaft having at a forward end a bit, the shaft reciprocally movable axially in the guideway to engage the fastener with the bit and drive the fastener axially forwardly from the guideway into a workpiece,the exitway having an axially, rearwardly directed strip supporting surface axially forward of the strip for engagement by the strip to support the strip against movement forwardly on the shaft driving a fastener axially forwardly.
