Publication number: 20020050506Abstract: A fastener driving tool includes a magazine comprised of a plurality of fastener slides, each of which carries a fasteners of a different size. The magazine is designed so that an operator may to choose to drive fasteners from any of the fastener slides. In one embodiment, the fastener slides are arranged around a central core. A rod supported by the tool's base and driver fits within the central core and provides an axis of rotation for the magazine. During rotation of the magazine, each slide can be aligned with the driver. Alignment of a slide is maintained by a position locking means. A feed means in each slide forces the fasteners down the slide and into the driver. In another embodiment, the fastener slides are arranged next to one another in the magazine. Each slide can be aligned with the driver by shifting the magazine laterally. A position locking means keeps the magazine in the proper alignment once a particular fastener slide has been chosen.Type: ApplicationFiled: July 16, 2001Publication date: May 2, 2002Inventor: Robert Hadfield

Patent number: 6279808Abstract: A nail guide mechanism, suitable for use with a wide variety of nail guns, having a mounting bracket to permit ready attachment and/or removal in the field. The guide mechanism, when mounted, is oriented about the channel defined by the nose of the nail gun. The guide mechanism includes a partially pre-compressed spring that induces a bias on a pivoting arm such that the arm is caused to protrude at least partially into the channel. The arm is thus positioned to continuously exert a force on the nails as they are driven down the channel past the arm. Because the spring is only partially pre-compressed, the positioning of the arm is responsive to changes in conditions inside the channel, such as when the head of a nail passes by the arm. The force exerted by the arm, under the influence of the spring, acts substantially along the radial axis of the nail, and is exerted on the nail during at least a portion of the time that the nail is being impelled by the driving mechanism of the nail gun.Type: GrantFiled: July 27, 1999Date of Patent: August 28, 2001Inventor: Mark E.

Patent number: 6273316Abstract: A fastener feeding mechanism for a power actuated gun (10, 310, 410, 510) having a track (16, 316, 416, 516) for holding a plurality of fasteners (18, 318, 636). Fasteners are biased by a spring (32, 372, 672) down the track towards a holding or latch mechanism (22, 322, 422, 522). The holding or latch mechanism has a retractable latch. The holding or latch mechanism holds a fastener in a predetermined position to be driven into a substrate. A guide (14, 314, 414, 514) attached to a barrel (12, 312, 412, 512) of a power actuated gun guides the barrel permitting the barrel to be advanced for firing and driving the fastener. After firing a bias on the guide causes the barrel to be retracted for the positioning of another fastener to be driven. The present invention greatly facilitates the driving of fasteners having a plate, and permits the driving of fasteners quickly resulting in more efficient and therefore less costly construction.Type: GrantFiled: October 14, 1999Date of Patent: August 14, 2001Inventor: Alfonso Losada

Patent number: 6173949Abstract: In a stapler for variably stapling a set or stack of sheets manually inserted through the stapler entrance path with different orientations, there is a sheet guide system with movable guide members automatically differently repositioned into different sheet guiding positions in the entrance path by the sheet stack insertion and its angle of insertion, including switching in between a corner angled stapling alignment position and a linear sheet edge aligned stapling position, respectively differently positioning the sheet stack for stapling. It may include a base plate, a pair of guide elements movably mounted on the base plate, and a fixed registration wall. The guide members in the corner angled stapling position may present opposing converging 45 degree angled edge registration surfaces to the inserted sheet stack. For edge stapling, the same guide members and/or the registration wall may present one, or two straight edge registration surfaces to the inserted stack.Type: GrantFiled: September 3, 1998Date of Patent: January 16, 2001Assignee: Xerox CorporationInventors: David S.

Patent number: 6145723Abstract: A combustion-powered, fastener-driving tool useful to fasten a dimpled membrane to a foundation wall, via a fastener and a polymeric plug, is arranged to drive a fastener from a nosepiece, through the plug and the membrane, into the wall. An actuating member mounted movably on the tool is movable thereon between an extended, tool-disabling position and a retracted, tool-enabling position. A workpiece-contacting probe is mounted to the actuating member so as to be conjointly movable with the actuating member. The probe includes a plug-holding member adapted to hold the plug as the fastener is being driven, having a tubular wall defining a recess adapted to receive the plug, and having two pointed elements in diametric opposition to each other, each having a point projecting inwardly from the tubular wall so as to press against the plug received in the recess. The workpiece-contacting probe includes a mounting bracket mounted to the actuating member.Type: GrantFiled: January 27, 1998Date of Patent: November 14, 2000Assignee: Illinois Tool Works Inc.Inventor: Harish C.

Patent number: 6131788Abstract: A device to improve attaching wires to a substrateby with a staple gun is disclosed. An elongated nose piece extends down from the front of the tool body and locks in position to hold the tool bottom a preset distance away from the substrate. The nose piece includes a recess to provide clearance for the wire as the nose piece is pressed against the substrate. The wire guide improves the operation of stapling wires by preventing the staple from crushing the wire and by aligning the tool over the wire so that the staple points are inserted a safe distance to each side of the wire. The present invention is an improvement over the prior art staple gun wire guides since it is a permanent part of the tool. It is slidably fixed to a vertical track at the front end of the tool. It does not increase the bulk of the tool front end and cannot be misplaced. In one embodiment the wire guide is internal to the tool in sliding contact with the plunger.Type: GrantFiled: December 9, 1998Date of Patent: October 17, 2000Assignee: WorkTools, Inc.Inventor: Joel S. Marks

Patent number: 6123245Abstract: The nailer has a horizontal nail magazine and an integral vertical column. The magazine horizontally feeds the nails through an inclined inlet port, into a vertical channel located in the column, and inside which is vertically slidable a selectively powered driver rod which hits and expels the nails through a nail outlet port. The vertical channel has a front and a rear wall adjacent the single nail located in the channel, and lateral walls. The inclined inlet port is located in the channel rear wall. When the driver rod is forcibly downwardly driven along the channel, it hits the upper inclined nail head with its flat lower abutment edge, thus gradually pivoting the nail into a vertical position as the nail is being driven towards the nailer outlet port. This results in the nail being pivoted from a position in which it is in transverse register with the inlet port, to a position in which it is in transverse register with the channel rear wall.Type: GrantFiled: April 16, 1999Date of Patent: September 26, 2000Assignee: Laboratoire Primatech Inc.Inventor: Jacques Maltais
