  • Patent number: 8534651
    Abstract: A temporary attachment device for securing a number of parts or sheets together has an elongated hollow body with three, slidable and spreadable prongs spaced apart 120°, protruding from an open end of the elongated body over a substantially Y-shaped spreader held in the elongated body and extending through the open end to more evenly and accurately maintain the spacing between and spread the three prongs. The three prongs and spreader more accurately fill pilot holes, after insertion into the openings and the prongs have outwardly facing heads, lobes or noses to more securely clamp at least two sheets of material together. The device may include an internal spring and a movable plunger to allow the prongs to be operated by the pliers, or may include a threaded shaft and a nut secured to the shaft to allow operation of the device by turning the nut and the shaft to slidably move the three prongs.

The clamp includes an sleeve member that is attached to the temporary fastener and a socket that attaches to the sleeve member and is axially adjustable therewith. The clamp attaches to the temporary fastener without modification of the temporary fastener and clamps the tool to the panel assembly. The clamp is adjustable for a variety of tool thicknesses and can be removed without removal of the temporary fastener.

  • Patent number: 6698736
    Abstract: A clamping and locating fixture includes a hollow body, a pin mountable to the body, a locking arm positionable within the body locatable between two positions and a drive pin moveable within the body to engage the locking arm. A workpiece can be directed to a clamping position by the guide pin. The pin includes an aperture allowing a locking projection of the locking arm to extend therethrough and over a workpiece to clamp the workpiece for a processing operation. The locking projection can be retracted through the aperture while the workpiece is being located or is being removed. The drive pin can be moved within the body to engage a cam follower of the locking arm. The drive pin can be supported during movement by one or more rollers mounted in the body. The drive pin can include a pin body and a pin member moveably associated with one another to selectively define the position of a cam surface.

  • Patent number: 6557229
    Abstract: A tool to assist in the installation of a waste disposer beneath a kitchen sink includes a central, threaded shaft with a flared bottom end supporting a lift plate which is cocked on the shaft so that it may be inserted into the top of the waste disposer. The tool further contains a threaded stabilizing plate which mates with the threaded shaft, and which is inserted and retained in the top of the sink strainer, so that the shaft and lift plate extend through the sink strainer and into the waste disposer beneath. When the lift plate is straightened on the shaft, and the shaft rotated relative to the stabilizing plate, the waste disposer is drawn up until it engages the adapter on the sink strainer, to which it attaches.

  • Patent number: 6439560
    Abstract: A clamp jig has a positioning pin provided at the tip of a cylindrical member, and a clamp arm is mounted in a slit formed in this positioning pin, so as to be able to swing and so as to be able to axially advance and retreat. A reciprocating shaft is connected to the clamp arm by a connecting pin, and a spring force is applied to this reciprocating shaft in a retreating direction by a compression coil spring. A plunger 35 brought into contact with the reciprocating shaft is mounted in a drive housing so as to be able to axially reciprocate, and a female screw member driven by a motor is thread-connected to a male screw member secured to this plunger. Accordingly, it is made possible to reliably perform positioning and clamping, of a member to be fixed, and unclamping thereof by a low-cost motor.

  • Patent number: 6371468
    Abstract: The present invention is a universal workpiece holder that includes a unique positioning hub and a plurality of clamping devices for clamping a variety of annularly shaped workpieces having different interior and/or exterior diameters. The positioning hub includes multiple sets of spokes, wherein when a particular set of spokes aligns with the clamping devices, the workpiece holder is able to secure a particularly sized annulus without distorting it. Moreover, upon rotating the positioning hub about its center and aligning a different set of spokes with the clamping devices, the workpiece holder is able to secure a differently sized annulus. Each set of spokes corresponds to a certain sized annulus, thereby eliminating the need for an independent workpiece holder for each differently sized annulus.

  • Patent number: 6342138
    Abstract: An electroplating rack includes a cathode flight bar from which depends an insulated rack bar over an acid bath. A clamp is fixed to the rack bar, and has a bridge electrically connected to the flight bar through a conducting core inside the insulated rack bar. The clamp has a main body made of plastic, which includes a slot in which protrudes the bridge. An electrically conducting spring clip is installed in the slot, and is formed of two arms continuously biased into a spreaded, opened condition in the slot. A screw carried by the main body, when rotated in a first direction, can force the spring clip into a closed condition, in which it can hold an article to be electroplated between its two arms, and in which one of the spring clip arms is forced against the bridge member. Thus, electrical current can pass through the rack flight bar and conducting core, then through the bridge member, the spring clip and finally into the article to be electroplated.
