Abstract: A fastener includes a round, blind hole or pocket in its head. Installation and removal of the fastener is accomplished with a tool containing an eccentric segment on the end of a shaft. When rotated within the pocket, the eccentric segment displaces laterally relative to the shaft to provide a friction grip to the lateral wall of the pocket. The strength of the grip is proportional to the applied torque. Eccentric displacement allows rotation but prevents the tool from spinning out of the fastener thereby eliminating cam-out and surface damage resulting from contact with a spinning tool tip. The eccentric head of the tool can be made disposable and to shear off when a predetermined torque is reached. The smooth-sided round hole offers no purchase for commonly available tools; making the fastener tamper-resistance. In another embodiment, the fastener includes a raised portion in the pocket. A tool having a complementary opening shears off the raised portion at a predetermined torque.

Abstract: Disclosed is a tool for both removing and tightening screw-on drains that is simple and easy to use, has a simple design and is easy to manufacture. The tool is capable of engaging an inner surface of a drain flange in a manner that is sufficient to transfer enough force to remove screw-on drain flanges and is capable of use with various designs and sizes of screw-on drain flanges. Different size cams and different lever arms used on the cams allow the tool to optimize the radial force to torque ratio for both removal and insertion of screw-on drain flanges. In addition, nubs are used at the bottom of the drain flange to engage arms that typically are used on drain flanges to further add to the resistance that can be provided between the tool and the drain flange and distribute forces in a dynamic, instantaneous and automatic fashion to optimize removal of the drain flange.

Abstract: A heavy duty, large self-forming socket having a plurality of retractable gripping pins bundled in parallel and held in a frame within a housing is disclosed. The frame is positioned axially within the housing by radially extending, elongated hold elements that are positioned circumferentially around the housing. Slots in the housing exterior allow efficient inspection of the position of holes into which the hold elements are installed. A collar with shelf around the center pin protects the bias spring for the pin from over-compression. The gripping pins may be held to the frame by spring clips. An adaptor is attached wherein a secondary operation is used to remove the adaptor from the square end of the socket. The self-forming socket is well suited for use with valves and controls for water, gas, sewage conduits and piping.

Abstract: Disclosed is a coupler that grips the internal surface of a torque receptor such as a pipe or driveshaft to be turned. When torque is applied to the coupler, one or more gripping surfaces are forced apart by a cam mechanism. The gripping surfaces tightly engage the internal surface of the pipe in response to movement of an internal cam. Torque applied to the wrench causes the pipe to turn. Because the wrench grips the internal diameter of a torque receptor, it can be used without damaging the external surface of the torque receptor, and used in very confined spaces. The gripping surfaces distribute the gripping load evenly across the pipe, which minimizes any deformation of the pipe.

Abstract: A universal socket is described which is suitable for use upon a myriad of fastening means whereupon at least a plurality of pins are capable of longitudinal axial movement in concert and in conformity with contact with a workpiece. This result is achieved by the incorporation of a biasing mechanism on the pins which biases the pins in a normally extended position, but which permits movement to a second retracted position. In one embodiment, the cross-sectional area of the pins is decreased in either a linear or non-linear manner from the outer periphery to the center of the socket. In operation, as the workpiece is inserted into the socket, the pins are moved in a longitudinal axial direction from their normally extended position to the second retracted position in conformity with the shape of the workpiece.
