Patent number: 5833480Abstract: A standoff ground connector for mounting a circuit board to a chassis in a piece of electronic equipment in a standoff grounded position relative thereto includes two pre-load form members, each including two opposed shanks with support portions for the circuit board. A mounting device including an arrowhead shaped portion and a contiguous portion of reduced width forms a detent mounting device for the circuit board. Inward and outward flexing of the arrowhead shaped portion causes the support portions of the pre-load form members to perform a wiping motion. Therefore, as the aperture of the circuit board moves from the arrowhead shaped portion into the detent position within the portion of reduced width, the pre-load form members perform this wiping motion.Type: GrantFiled: February 11, 1997Date of Patent: November 10, 1998Assignee: Illinois Tool Works Inc.Inventor: Ronald Austin

Patent number: 5707244Abstract: A standoff ground connector for mounting a circuit board to a chassis in a piece of electronic equipment in a standoff grounded position relative thereto includes a support platform onto which a circuit board may be mounted and two legs extending from the support platform for connection to the chassis. At least one pre-load form member having an apex extends between the legs. The apex, which protrudes beyond the support platform relative to the legs, is resiliently depressed toward the support platform when a circuit board is attached thereto. The depression of the apex causes the pre-load form member to bias the legs apart from one another, thereby strengthening the ground connection between the standoff ground connector and the chassis. The apex presses back on the circuit board, thereby strengthening the ground connection between the standoff ground connector and the circuit board, so that the circuit board is effectively grounded to the chassis.Type: GrantFiled: July 3, 1996Date of Patent: January 13, 1998Assignee: Illinois Tool Works Inc.Inventor: Ronald Austin

Patent number: 4903880Abstract: A magazine assembly for a fastener driving tool has an elongated fastener carrier defining a fastener feed path. The carrier is pivotally mounted about an axis parallel to the fastener feed path for movement between an operative, refill and an unjam position. In the operative position, the elongated carrier is latched by a latch assembly disposed in the forward portion of the tool. A pusher advances the fasteners forward to a nosepiece assembly. In one embodiment, retraction of the pusher releases the latch allowing the elongated carrier to pivot about an axis parallel to the fastener feed path under the influence of a spring to the refill position. In an alternate embodiment, the latch assembly is provided at the rear of the tool and is not interlocked with the pusher. A nosepiece assembly, secured to the forward end of the tool, defines a fastener drive track for guiding fasteners driven into a workpiece.Type: GrantFiled: September 28, 1988Date of Patent: February 27, 1990Assignee: Duo-Fast CorporationInventors: Ronald Austin, Dale M.

Patent number: 4260092Abstract: A tool for driving fasteners includes a driver and a device for actuating the driver through a driving stroke. The tool is operated by a trigger assembly that includes a manually actuated trigger pivotally mounted on the tool and a lever pivotally mounted at a first end to the trigger. Also included on the tool is a safety assembly that before the tool can be fired must be actuated prior to actuation of the trigger. The safety mechanism includes a push rod slideably mounted within the tool with a first end engaging a safety yoke and a second end adjacent the lever of the trigger assembly. The safety yoke is slideably mounted on the nose of the tool and is adapted to extend below the nose of the tool to engage the workpiece upon placement of the tool onto the workpiece. As the tool is placed against a workpiece prior to actuation of the trigger, the yoke and, thus, the push rod are moved upwardly until the second end of the push rod engages the lever placing the trigger assembly in an operative mode.Type: GrantFiled: July 2, 1979Date of Patent: April 7, 1981Assignee: Duo-Fast CorporationInventor: Ronald Austin
