Abstract: An attachment for a portable hand-held screw driving tool is provided for use with collated strips of screws. The front portion of the attachment is movable to a great extent, to thereby allow the tool to drive screws almost directly at the corner of two walls. A front “nose piece” is pressed against one of the walls, which causes the nose piece to move rearward “into” the remainder of the tool, in a “first stage” of movement. A screw is indexed to its drive position, and a drive bit is abutted against the screw head during this first stage. The nose piece is pressed further into the tool, which also causes a “feed tube” to move rearward “into” the remainder of the tool, in a “second stage” of movement, which rotates the screw as it is emplaced into the wall.

Abstract: A screw feed and driver assembly which may constitute a part of a screw driving tool of the type having a prime mover, a speed and torque determining gear assembly and a clutch; which can constitute an accessory for a clutch containing manual feed power screw driver; and which, combined with a clutch, can comprise an accessory for a standard manual power drill. The screw feed and driver assembly comprises a feed housing with a slide body mounted therein and shiftable between forward and rearward positions. The slide body is biased to its forward position. The slide body receives a strip bearing screws. A contact foot is mounted on the slide body and shifts the slide body rearwardly when pressed against a workpiece. A screw driver, affixed to the clutch, extends into the slide body. The slide body contains a pawl and feed sprocket assembly. The sprocket engages notches in one edge of the screw bearing strip.

Abstract: An improved magazine for a fastener driving tool having a two piece back plate allowing easy access to the drive track for removing jammed fasteners from the tool. The magazine consists of a first fixed rail having a back plate section perpendicular to the rail, and a second rail slidable with respect to the fixed rail, having a second back plate section perpendicular to the rail. When the magazine is in the fastener driving position, the back plate sections provide extra support for the drive track.

Abstract: A modular tool functions to drive nails or staples. The tool uses a common air motor and housing and has interchangeable magazines and handle assemblies for nails and staples, respectively. Improvements in the air motor cylinder sleeve, the firing valve, the remote valve, the trigger, the stapler follower motor and magazine, the drive station access door and latch for both stapler and nailer, the nailer magazine and follower, and other features are included.

Abstract: A drywall tool provides tactile and audible feedback to the user, as a fastener is driven by frequent multiple blows, to indicate when the fastener is properly driven, and the drywall dimpled, without tearing the paper facing of the drywall. Dimpling apparatus and a firing valve for controlling the multiple blows are described. A cam is provided to withdraw the magazine follower from the last fastener in a strip to avoid jamming or damage by a descending driver. Tool apparatus permits use of lightweight, synthetic parts.
