The nut is picked up on an assembly that includes a split spring ring which engages the bore of the nut. The spring ring is mounted on a fixed member, which also includes a hexagonal key for preventing rotation of a bolt as the nut is threaded onto it. A rotating nut driver moves over the outside of the nut picked up by the nut pickup assembly for threading the nut onto a bolt.Type: GrantFiled: June 17, 1991Date of Patent: November 24, 1992Assignee: VSI CorporationInventor: John A.

Patent number: 5025688Abstract: A fastener drive tool for applying a rotational torque to a threaded fastener for driving the fastener into or out of a workpiece. The drive tool has an elongated shaft portion with a free end which is selectively controllably engageable with a recess formed in the fastener. The free end is formed with a fastener engaging expansion portion. The expansion portion is operated by a draw shaft being selectively lockable in a bit retaining position. The expansion portion of the bit portion creates substantial fastener retaining forces on the opposing internal surfaces of the fastener recess in which it is inserted.Type: GrantFiled: May 22, 1990Date of Patent: June 25, 1991Assignees: Ryder International Corp., Textron Inc.Inventor: Richard M. Davis

Patent number: 4924736Abstract: A gripping screw drive bit for use with conventional drive sockets which utilize non-magnetic means for gripping and retaining Robertson, TORX, and hexagonal screws and bolts. The gripping bit comprises two mating members. The gripping action is provided by the misalignment of the two members of a composite gripping bit, within a screw head recess, when a minimal amount of torque is exerted upon the composite gripping bit by a drive socket.Type: GrantFiled: May 4, 1989Date of Patent: May 15, 1990Assignee: A.T. & G Company, Inc.Inventor: Ben V. Bonner

Patent number: 4890521Abstract: A power driven screw driver self-gripping composite bit in the form of a pair of mirror image halved elements united at a common oblique interface providing a square end driver for reception in a screw head formed with a combined socket that accepts both a square end bit and a cross-point bit. Each halved element driver portion defines a trapezoidal cross section having major and minor parallel exterior side surfaces, a complete side surface extending at right angles to its major and minor surfaces, and a diagonal-like interface. The composite bit holder resiliently biases the halved elements interfaces into coextensive flush contact normally defining a square end driver.Type: GrantFiled: May 15, 1989Date of Patent: January 2, 1990Assignee: Crysler Motors CorporationInventor: Alfred A.

Patent number: 4838131Abstract: In one embodiment, there is provided an axial nut starter having a nut engaging member which can be used with a wide range of nut sizes. The nut engaging member is in the form of a stepped series of stacked, coaxially aligned cylinders. The base, or the largest cylinder, of the nut engaging member is attached to an elongated handle. The top, or the smallest cylinder, of the cone is inserted into the nut until the wall of one of the cylinders frictionally engages the threads of the nut and the face of the nut shoulders against the top of the next larger cylinder. Unitary rotational movement of the handle and the nut engaging member starts the nut on the fastener. In another embodiment, an offset nut starter is provided which permits the starting of a nut on a fastener when it is impossible to reach the fastener along its axis.Type: GrantFiled: February 9, 1988Date of Patent: June 13, 1989Inventor: Clark J. Rhoades

Patent number: 4659004Abstract: A device is disclosed for attaching to or removing modular electronic components from a substrate which is adjustably positioned beneath a heater means delivering a flow of uniformly heated air. The heated air is directed to the sides of the component to melt solder associated with terminals thereon by a series of changeable nozzles which can be moved into or out of registry with the component. Vacuum means is also provided for contacting the component to position it on or remove it from the substrate.Type: GrantFiled: September 10, 1984Date of Patent: April 21, 1987Assignee: Pace, IncorporatedInventor: Robert Fridman

Patent number: 4442737Abstract: Removal of a screw-on type of thread protector from a pipe is achieved by this invention with uniformly applied pressure about the entire circumferential surface of the thread protector. Thus an inflatable type grasping urethane boot of a wrench mechanism is positioned circumferentially about and adjacent to the grasping surface of a generally cylindrical screwed-on thread protector before inflation. The boot is connected with a chamber which retains a fluid such as air under pressure and thus is firmly coupled in grasping connection with the thread protector by inflating in place from an air pressure hose for example. After removal of the thread protector, the chamber may be deflated to release it. The wrench is manipulated to rotate the inflated boot by rotation of a shaft co-axially located with the pipe to which the inflation valve may be attached for ready access. Preferably, the boot is supplied with a tread design to give better grasping characteristics.Type: GrantFiled: April 14, 1982Date of Patent: April 17, 1984Inventor: Robert M. Miner
