  • Patent number: 8020840
    Abstract: A versatile clamp which consists, at least in part, of at least one extendable arm, one fixed-length arm, pivotable clamping legs on the distal ends of the fixed-length arm and extendable arm, and locking means; wherein clamp adjustments, by the user, to the extendable arm and pivotable legs are retained by a locking action, which, prevents an inadvertent change of the extendable arm's effective length and the clamping legs' angular orientation from their set positions. The combination of a variable-length extendable arm and variable angular positioning of the legs enable a single versatile clamp to be used in a variety of clamping configurations. The versatile clamp may be easily made, without the use of any tools, to clamp onto thick and thin materials, alike, and to perform in applications which require an offset clamping operation. The versatile clamp may also feature one or more interchangeable clamping arm extensions and legs.

  • Patent number: 6098498
    Abstract: A seat for guiding screws and nails includes a block having two opposite vertical lateral sides and two opposite ends, each of the sides being formed with a plurality of semi-circular holes, and a rectangular opening extending through the two opposite ends, whereby a jaw of a longnose pliers may be inserted into the rectangular opening of the trapezium block to keep the trapezium block at a fixed position thereby enabling a screw or the like to be guided safely, rapidly and accurately by the vertical passage between the semi-circular hole and another jaw of the longnose pliers to a workpiece.

  • Patent number: 6000686
    Abstract: A locking, three-way clamp for applying a bi-directional vector force against one or more workpieces. The clamp 10, of the present invention, includes a handle 22, first and second opposing jaws 24 and 26, respectively, a jaw actuation lever 28, a threaded adjusting screw 30 and a toggle lock 32. Second opposing jaw 26 pivots, in relation to first jaw 24, about a central pivot point 34. First and second opposing jaws 24 and 26 each include a distal end 25 and 27, respectively. A workpiece restraint member 36 can be utilized for providing a rigid planar surface for engagement with a workpiece. The locking three-way clamp 10 of the present invention also includes an engagement device 50, on the distal end of each jaw, that pivots inward towards the restraint member 36 thus applying a vector force having x- and y-component vectors that forces a first workpiece against a second workpiece and simultaneously forcing the clamp 10 towards the workpieces 120 and 140.

  • Patent number: 5862552
    Abstract: A fishing pliers including a pair of gripping jaws having replaceable gripping inserts with progressively finer knurled gripping surfaces, so that the gripping jaws can be used on both small and large objects and for many different tasks. The fishing pliers also include a pair of cutting jaws having replaceable cutting blades with cutting edges. The cutting edges are positioned so that their common cutting line is offset from the pivot axis of the fishing pliers so that the cutting jaws produce both a slicing cutting motion and a compressive cutting motion, making for easier cutting and reducing wear on the cutting blades.

  • Patent number: 5863033
    Abstract: A dynamic self-adjusting dual-action clamp comprising a first clamping component defining a plane and generating clamping force along a first clamping axis in that plane, and a second clamping component generating force in a second clamping axis substantially perpendicular to the first clamping axis, but within the same plane as the first clamping axis. The invention further includes elements used to adapt a standard spring actuated pliers-type clamp to convert such clamp to the dual-action clamp described above.

  • Patent number: 5810881
    Abstract: A surgical needle holder has the facing surfaces of its jaws lined with memory alloy which is soft enough to distort around a needle when gripped between the jaws. A better grip on the needle is thus achieved. The surfaces of the inserts may be profiled with ribs to allow the alloy to be subject to a greater pressure per square centimeter locally and so more readily deformed.

  • Patent number: 5732461
    Abstract: A hand tool for supporting a jaw-type electrical tap thereon during the positioning of the same with respect to an electrical wire and for clamping the tap thereon comprising a pair of elongated handles which are pivotally secured together and which has a tap support operatively secured thereto. The tap support is designed to be removably connected to the electrical tap so that the electrical tap may be positioned with respect to the electrical wire and clamped thereon by pivotally moving the handles towards one another to cause the jaw members thereof to clamp the tap onto the wire.

  • Patent number: 5662665
    Abstract: A surgical instrument for holding a suture needle is disclosed. The instrument is of scissors configuration with elongated arms having finger loops at one end and jaws at the other end to grasp a suture needle. This improved instrument has specialized jaws containing a transverse channel that securely holds a suture needle at a right angle to the axis of the needle holder. The width of the transverse channel automatically adjusts to the size of the suture needle as it is being placed in the needle holder. This improved configuration significantly reduces the long standing problem of suture needle twisting or rotation in the needle holder jaws as the surgeon passes the needle through tissue.

  • Patent number: 5607344
    Abstract: An apparatus for gripping and holding glass during a glass grinding process. The glass gripping and holding apparatus includes an elongated top shank and an elongated bottom shank pivotally connected, with the top shank being inclined toward the bottom shank. Both shanks each have a respective glass-gripping end portion that oppose one another in generally parallel disposition when gripping a piece of glass. A spring operatively connects the shanks toward each other, biasing the glass-gripping end portions of the shanks toward each other. A generally circular boss is located on the bottom shank to facilitate mobility of the apparatus across a table surface of a glass grinder.

  • Patent number: 5537898
    Abstract: First and second jaws are arranged to hold a key for fitting the key to a lock. A first jaw includes an anvil surface and a second jaw includes a lateral cutting lip that is arranged to cut slightly into the key when the latter is clamped securely in the tool whereby to hold a key firmly in a rigid extension of the tool. The second jaw includes an integral post that fits in the usual aperture in the head of the key to help stabilize the key in the tool. Also, the tool includes an abutting edge that forms a stop in the inserted position of the key in the tool.

  • Patent number: 5485641
    Abstract: A composite, non-electrically conductive, non-sparking, non-magnetic and lightweight cutter/plier hand tool has two pivotally interconnected lever members, each of unitary, one-piece construction and formed by compression molding of multiple plies of a discontinuous random glass fiber-reinforced plastic sheet molding compound. Fixed to the jaw of each lever member is a ceramic insert made of transformation toughened zirconia, formed by dry compression and then sintering of a powdered form of the ceramic material. Each insert has a serrated gripping portion and a cutting portion, with cutting surfaces on the opposed inserts operating in shearing relationship. Three versions of the inserts are disclosed.
