  • Patent number: 6701560
    Abstract: A nail-pulling tool has a two-piece proximal handle pivotally joined with a two-piece distal jaw by a pivoting means. The distal jaw is operated like a standard hand tool with compression of the handle causing the jaw to close, and vice-versa. The distal jaw has an elliptical surface so that with the distal jaw resting on a work surface and closed about a nail protruding from the work surface, and with the handle laying adjacent the work surface, raising the handle away from the work surface in an arc, causes the nail to be pulled from the work surface at an ever increasing rate. Axially oriented jaw teeth provide improved gripping and a pair of tongue and groove opposing surfaces enable cutting and further improved gripping. A hammer surface enables driving of a nail into the work surface rather than pulling it out, and a claw element enables pulling a nail head up so as to be better gripped by the tool.

Inside the sheath is parallel spaced apart insulation covered wires and a core member containing an uncovered ground wire between the insulation covered wires. The sheath has spaced apart curved sides conforming to the covered wires. The tool has spaced apart first and second jaw members adapted to be pressed together. The jaw members have cutting edges that receive a portion of the first cable along its length. The cutting edges define an opening configured to cut the sheath and the core without significantly cutting the insulation on the wires or the unsheathed ground wire when the jaw members are pressed together to form the opening. The portion of the sheath is then removed in one continuous process.

The springs press against the base of a pliers jaw or other tool bit or blade, or a spacer, to keep each tool blade, jaw, or bit in a folded position or support it in a deployed position. Additional frame side members each include a flange and support a spring and one or two additional tool blades or bits. The pivot axles interconnect the handle frame side members and the tool bits.

  • Patent number: 6430767
    Abstract: A tool that enables the forming of a hole in irrigation pipe, and the placement of an emitter device into that formed hole, includes a pair of elongate plier half-members connected at a pivoting joint. A first jaw includes an inwardly-directed hole punch member, while the second opposed jaw includes an inwardly-directed concavity to engage a piece of irrigation hose, such that closure of the jaws causes the hole punch to pierce a hole in the irrigation pipe. The jaw ends each include semi-cylindrical cavities sized to hold the cylindrical body of an emitter, to facilitate forcible insertion of the spike of the emitter into the hole previously formed in the irrigation pipe.

  • Patent number: 6314629
    Abstract: A tool is disclosed for the removal of quick release couplings from a conduit. The tool has a body that is divided into a rotatably connected gripping portion and a release portion. Handles are connected to the body to activate the clamping and releasing action of the tool. Compressing the handles causes the gripping element to compress and the gripping portion and the release portion to rotate around the connection, creating a distance between the gripping and release elements. The release element has a pair of plates with neither, one or both of the plates being movable. Preferably the top plate has a spring member that retains the top plate adjacent the lower plate, thereby enabling a conduit to snap in and be maintained between the two plates. The clamping member can have a flat surface or at least one arc, and in come embodiments, the receiving member is a mirror image of the clamping member. An optional guide can be used adjacent the clamping member to prevent side to side movement.

  • Patent number: 6282996
    Abstract: A folding multipurpose tool including adjustable locking pliers with an over-center locking mechanism to retain the jaws in a gripping condition. The jaws of the locking pliers can be folded into the handles of the tool to produce a compact folded configuration. A latch mechanism in the tool handle retains a selected one of several folding tool bits or blades in an extended position for use and includes an abutment arrangement to prevent such a selected tool bit from being extended too far. A spring associated with a tool bit driving socket retains separate tool bits and resists inadvertent removal of an adjustment screw element of the locking pliers. Upon removal of the adjustment screw element, special bits, such as a corkscrew, can be screwed into the tool bit driving socket.

  • Patent number: 6233769
    Abstract: A hand tool such as a knife or a combination tool includes multiple blades, each independently rotatable on a common axle between a closed position within a handle of the tool and an open position extending from the handle. Each blade is positively but releasably locked into its open position. Those blades which remain closed are biased toward the closed position when the opened blade is locked into position and also as it is opened and closed. A single locking, releasing, and biasing mechanism serves all of the blades in one handle.

  • Patent number: 5887327
    Abstract: An improved pneumatic tool for the removal and application of tire cross chains configured having a manually actuated valve connected at its inlet port to a compressed air source and at its outlet port to a pneumatic diaphragm motor for actuation of a diaphragm. The control valve includes an air bleed port which allows air to escape through the valve when the trigger or other operating mechanism is released deactivating the valve. This feature allows an almost immediate recovery of the jaws to the open position. The pneumatic tool for the removal and application of tire cross chains also includes a fixed jaw support assembly having a base plate for attachment to the face of the pneumatic diaphragm motor, the fixed jaw support assembly having a pair of upright members attached to the base plate and extending perpendicularly and in spaced apart relationship to one another to accommodate the attachment of the fixed and the moveable jaws between the two upright members thereto.

  • Patent number: 5536270
    Abstract: Surgical crimping pliers have operating handles and connected, opposed jaws. The jaws define opposed recesses for carrying and crimping a tubular crimp member, which is preferably of oval configuration for carrying a plurality of multistrand cable sections so that, upon crimping, the cable sections are secured together. A capstan is carried on one of the handles for winding a plurality of cable portions so that tension may be placed on both ends of a cable loop array wound about a bone structure, to provide a predetermined, quantitative tension. Then the cable sections within the crimp are secured together by collapse of the crimp. A multistrand cable is preferably used, which exhibits great advantage over single strand wire, and which carries surgical needles of differing type secured to each end thereof.
