Abstract: An interface component is provided for use in combination with a clamp or compressive tool imparting a compressive force against respective planar contact surfaces of two components being joined at a miter joint. The interface features an elongated member having a projection projecting away from a top surface in a substantially circular path. The curved surface provides a means to redirect the compressive force communicated against said curved surface to the miter joint at a substantially normal angle.
Abstract: The support system and method enables exact and preferably machine assisted manual location and height placement of a vacuum operated hold down with rigid pre-set support on a conventional working table. A height adjustable jack screw support with angularly flexible hold down enables a holding support engaging the bottom of a work piece even where a lower surface of the work piece has an irregular shape due to the ability of the upper cup support to passively tilt to engage the work piece.
Abstract: A fixture is provided for supporting a vehicle hub assembly during manufacturing operations that include rotating the assembly. The fixture includes a base with an upper surface, a linearly movable housing slidably supported on the base, an adjustable support block defining two selectable bores, each for slidably receiving a stud from one of two corresponding hub assembly types, and a handle for sliding the housing along the base. An operator checks the type of hub assembly to be worked on and rotates the support block if necessary to select the proper bore. The operator then slides the housing, causing the bore in the support block to slidably engage the stud. Each bore is configured within the support block so as to be accurately aligned with a stud on a corresponding hub assembly when supported in a jig, thus, allowing repeated fixture and hub assembly engagement without any additional adjustments.
Abstract: An integral U-shape clamping block structure comprised of a clamping block and a fixation arm respectively extending rearward, and multiple fixation holes and screws being provided sideways on each fixation arm to be incorporated to both sides of a neck of jaw, thus to ensure the clamping strength and expanded width of a clamping surface to improve clamping capability, thus to facilitate combination or retrofit of the clamping block and the neck of jaw
Abstract: A security hardware device used to hold multi-leafed materials, for example, telephone books, which device has an inner box within an outer sleeve, wherein the inner box has a first end with a toothed grip and a second end with a means for receiving a screw; and the outer sleeve has a first open end for receiving the inner box and second closed end, and wherein the second closed end is provided with a toothed grip and further provided with a hole for passing a screw through the outer sleeve and into the means for receiving a screw so that, as the screw is turned into engagement, the inner box is drawn into the outer sleeve, and a means for attaching the device to a surface.
Abstract: A tool which is adapted to orient a work piece for machining. A first embodiment of the tool is adapted to be removably mounted on the fixed jaw of a pair of relatively shiftable jaws of a machine vise. The tool has an arm pivotally mounted thereon, and the arm has a surface for supporting and orienting a work piece relative to the jaws. A curved slot in the tool for receiving a locking device carried by the arm, whereby the arm can be moved into any one of a plurality of infinitely variable positions with the aid of a protractor to support a work piece when the work piece is between the jaws. Holes formed into the arm receive a pin for supporting the work piece. Other embodiments are a tool for orienting the compound of a lathe.
Abstract: A pair of jaws moveable with respect to one another whether mounted in a hand held sealer or desk mounted sealer, compresses, heats, elongates, spreads and welds liquid filled tubing placed therebetween. Variants of the pair of jaws provide means for serially or simultaneously segmenting the tubing into a plurality of sealed compartments. The pair of jaws are electrically connected to a source of RF energy as the plates of a variable capacitor in an RF resonant circuit. The flow of RF energy across the pair of jaws, which energy heats the tubing and, in conjunction with mechanical pressure, makes the weld, is a function of timing and of the spacing between the jaws which spacing affects the degree of resonance of the RF resonant circuit.
