  • Patent number: 8857488
    Abstract: A portable assembly for securing a plastic fitting to a plastic pipe by employing fusion or thermal sealing is disclosed. The assembly is secured to the outer circumference of a plastic pipe at a desired location. The assembly can be secured at any longitudinal and lateral position along a plastic pipe. A heater heats both the pipe and the fitting to the point where they begin to melt. The heater is then removed and the fitting is pressed onto the surface of the pipe, thus fusing the fitting to the pipe. After cooling, the assembly is removed and the surface of the pipe within the interior of the fitting is drilled or removed. This now enables fluid within the pipe to be sent to the fitting and onto distribution lines which are connected to the fitting.

  • Patent number: 6855033
    Abstract: A gas turbine component blank is shaped by clamping the gas turbine component blank into a fixture that accurately positions the gas turbine component blank in three dimensions. The positioning is accomplished against stops accurately machined into a base of the fixture, by first supporting the gas turbine component blank on one set of stops that prevents movement in the direction perpendicular to a plane of the base, and then operating a movable clamp to force the gas turbine component blank against other sets of stops that limit the movement of the gas turbine component blank in directions lying in the base plane. The clamp has a compound movement that simultaneously forces the gas turbine component blank against stops that prevent movement in orthogonal directions lying in the base plane. The gas turbine component blank is thereafter shaped, preferably by grinding the sides of the root precursor of the gas turbine component blank.

  • Patent number: 6062552
    Abstract: A cutter clamp assembly for holding the elongated strip of tire material during the cutting process, whereby predetermined lengths of tire material are created to be formed into a tire. The cutter clamp is an air actuated clamp that is pivoted into engagement with a sidewall section of the elongated strip of tire material as air suction from an air manifold holds the entire elongated strip down so as to assure a uniform and even cut. The cutter clamp includes a clamp bar that is spring loaded by a tension bar such that during engagement the clamp bar evenly distributes a force along the entire sidewall adjacent to the cutter such that an even cut is started upon contact by the cutter with the elongated strip of tire material, whereby the air suction manifold holds down the entire elongated strip during cutting.

  • Patent number: 6042469
    Abstract: A mechanism for gripping an object employing a set of jaws which are adjusted to fit the size of the object by means of a limit or sizing stop device. The object is gripped by the jaws secured to the end of a stationary lower member while a movable upper member grips the opposite side of the object. A post operably supports a piston which is pivotally connected to the end of the upper member so that the piston, when moved up and down under pneumatic control, causes the jaws to move together or spread apart.

  • Patent number: 5918868
    Abstract: A fixturing device, usable with various fixturing components as a universal modular fixturing system, has a slot and a shaft, the slot and the shaft intersecting and having a common plane of symmetry, the fixturing device having a plurality of transverse bores intersecting the slot and the shaft, perpendicular to the plane of symmetry. The fixturing device is used according to one or more of three clamping techniques. The first clamping technique is back-clamping in which a workpiece having a threaded recess is clamped by a bolt from the back of the slot. The second clamping technique is relocatable clamping in which a clamp support supporting a clamp clamping a workpiece is displaceable along the shaft. The third technique is lever-arm clamping in which a lever arm, pivotally mounted on a pin located in one of the transverse bores, is rotated to clamp a workpiece.

  • Patent number: 5911413
    Abstract: An apparatus for adjusting the position of a motor and for preventing the motor from being inclined when a belt is assembled to a motor assembly. The apparatus has a pulling section for pulling the motor and a pushing section for pushing the motor. The pulling section has a finger which grips the motor and pivots by a pneumatic cylinder. The pushing section pushes the motor against a pulling force of the pulling section so that the pivot movement or inclination of the motor can be prevented. The belt is easily assembled to the motor assembly, and the productivity of the motor assembly is increased.

  • Patent number: 5868099
    Abstract: First and second pairs of arms are respectively disposed at opposite ends of a support structure. A constrainable member (e.g., a spring) is supported at its opposite ends by corresponding ones of the arms in the pairs. This is the only constrainable member in the page clamping device. When the spring is unconstrained, the arms in each pair are normally closed. The arms in each pair are pivotable independently of the arms in the other pair. The arms in each pair have at first positions camming peripheries which cause one of such arms to pivot when the other of such arms is pivoted. The arms in each pair have at second positions camming peripheries which provide a stable relationship between the arms when the arms are in an open position. The arms in each pair are disposed on the opposite sides of a book from the arms in the other pair. With the arms in the open relationship, the pages can be easily turned.

  • Patent number: 5765820
    Abstract: A three-way spring clamp is provided that is useable as an edge clamp for applying clamping forces to workpieces in three directions. The clamp includes two lever arms, each having a jaw end and a handle end. The lever arms are pivotally connected to each other at a pivot point located between the jaw ends and the handle ends such that the lever arms can be moved between a closed gripping position in which the jaw ends are proximate to each other, and an opened position in which the jaw ends are spaced apart. A coil spring is provided for biasing the lever arms toward the closed gripping position. A spring engagement member is mounted between the lever arms. The engagement member includes a central body portion engageable with a surface of an article to be clamped. The body portion is positioned between the pivot point and the jaw ends and may have a generally concave configuration from the perspective of the pivot point when the lever arms are in the closed gripping position.

  • Patent number: 5737820
    Abstract: A clamping tool designed for clamping sheet metal runners onto the side panels of drawers comprises an elongated grippable casing, at one end of which is a clamp (27, 127) composed of a pair of jaws (20, 21, 121) designed to grip a clamping area of a runner clasping the edge of a side panel of the drawer. Inside the casing is a actuator (18, 118) for moving a wedge-shaped element (19, 119). At least one jaw (21, 121) of the pair is made on the extremity of a lever (22, 122) having its other extremity (24, 124) slidingly resting on the wedge-shaped element (19, 119). Upon actuation of the actuator, the wedge (19, 119) slides over the extremity (24, 124) of the lever (22, 122) to rotate it around a pivot (23, 123) lying between the extremities and shift the jaws towards each other.

  • Patent number: 5695593
    Abstract: A lid is sealed to an integrated circuit package by a method that uses a spring biased pressure foot that is structurally carried by a secondary loading jig to impose sealant curing load on the lid. The pressure foot is retracted against the spring bias while secondary jig index pins are meshed with corresponding sockets in the fabrication boat that are aligned with the package position on the boat. When the pins and sockets are meshed, the pressure foot is released to apply optimal assembly force at the package center normal of the package lid plane.
