  • Patent number: 5839638
    Abstract: A power fastener driving tool, like a pneumatic trim nailer, of the type for driving fasteners supplied from a collated strip of fasteners disposed in a magazine of the tool. The magazine is coupled to a nose-piece of the fastener driving tool, wherein individual fasteners are sequentially fed into a channel of the nose-piece and driven axially through the nose-piece by a driver blade and into a workpiece. The fastener driving tool includes an improved work contacting element that provides for improved visibility of the nose-piece, an improved depth of drive adjustment for accurately adjusting the work contacting element, an improved hinged nose-piece assembly, and an improved two piece magazine assembly formed of extruded components which provide an accurately dimensioned channel for receiving fastener strips, among other improvements.
