Abstract: An automatic assembly machine with a rotatable socket adapted to be advanced downwardly through an active stroke to drive a hex head screw into a workpiece. Screws are supplied one at a time to the socket by a loading mechanism having a pair of jaws adapted to close and open to grip and release a screw. While the jaws are closed, a screw is forcibly blown into the jaws through a pneumatic supply tube. As the socket retracts, the jaws are shifted transversely inwardly toward the socket and move beneath the socket as soon as the socket moves upwardly past the jaws. Thereafter, the jaws are moved upwardly along the same path as the socket but at a speed greater than the speed of the socket to enable the jaws to overtake the socket and place the screw into the socket. When the socket starts its downstroke, the jaws move downwardly away from the socket and are cammed open to release the screw.

Abstract: A clamping device for rectangular configurations characterized by two opposed jaws each having right-angled jaw portions and each pivotally mounted on separate support means for movement to and from each other so that the jaws form rectangular openings with self-adjusting aspect ratio for holding a rectangular workpiece.

Abstract: A stop changer tool for removal of an in-service valve under pressure and comprised of a displaceable shaft assembly supporting at one end an axially compressible elastomeric plug adapted to be inserted through the valve into the upstream pipe. The plug is mounted between a pair of restraining ends such that displacing the shaft assembly in a withdrawal direction draws the restraining ends toward each other to compress and diametrically enlarge the plug until a pressure sealing engagement is achieved with the pipe surface thereat. The restraining ends are formed of laterally displaceable contiguous elements having predetermined face angles on opposing surfaces whereby they are relatively displaced laterally outward concomitantly with compression of the plug so as to substantially restrain the plug against axial extrusion.

Abstract: This tool permits rapid and easy stripping of the outer insulation from cxial cables or the like. The end of the cable to be stripped is first inserted into a gauging hole in a block of insulating material. A pair of blade-shaped electrical heating elements are clamped against opposite sides of the cable at the mouth of the hole and the cable rotated to form a thermal circumferential cut in the outer insulation. The cable end is then placed in another jig with a V-shaped groove therein and a blade-shaped heating element at the bottom of the groove. A second similar heating element is arranged above the groove and the cable. These two heating elements produce diametrically opposed longitudinal cuts in the insulation, after which two pieces of the insulation can be easily removed.
