  • Patent number: 5826338
    Abstract: A multipurpose tool may have several tool elements which pivot into storage positions in profiled handles attached to one of a pair of pliers jaws. A wire-cutter portion of each pliers jaw includes a sharp edge and a notch located at the throat of the pair of jaws, adjacent the sharp edge. The notches face toward each other to support and shear wire, but the bottoms of the notches are prevented from passing each other so that bulging material at the bottoms of the notches does not cause the jaws to bind against each other.

  • Patent number: 5745997
    Abstract: A multi-purpose folding tool including a pair of folding scissors, in which a scissors blade is movable about a pivot shaft, between a stowed position and a deployed position in which a stop prevents the blade from moving further with respect to the handle because of pressure on the handle in the direction needed to close the scissors blades in a cutting stroke. A rocker is moved by a spring in the tool handle and which in turn urges a movable scissors blade toward an open position. In one embodiment two handles are folded about respective scissors blades to house the blades, and four springs hold the handles together with the folded scissors stowed within the handles. When the blades are deployed one of the springs holds each blade in position with respect to the handle while the other spring urges the blades toward an open position, through action of a rocker.

  • Patent number: 4557034
    Abstract: The tool includes a pair of handles which combine to form a hand grip for manipulation of the tool. When the handles are closed, a support element is displaced from its illustrated home position within the head portion, engages a connector and displaces it forwardly against a die to crimp the connector element to the multi-conductor wire positioned in the connector and effect electrical contact between individual contact elements in the connector and the conductors in the multi-conductor wire. The tool also provides for stripping the end of the wire to fit within the connector. Guide elements with upwardly open yokes on one handle accommodate the wire, and blade elements on the other handle provide a slicing action on opposite sides of the sheath of the wire as the blades engage the sheath as the handles are closed so that the sheath may be stripped to expose the conductors for insertion into the connector.

  • Patent number: 4536939
    Abstract: A tool (20) is provided for terminating an end of a telephone cord or inside wiring with a modular plug (21). The tool includes a housing (81) having a cord or inside wiring-receiving opening at one of its ends and a plug-receiving nest (122) at an opposite end. The tool also includes a rocker (82) which is mounted pivotally in the housing and which has a first end adjacent to the cord-receiving end of the housing and a second end adjacent to the nest. After and end portion of a cord, for example, is inserted into the cord-receiving end of the housing, a user depresses the adjacent first end of the rocker to cause jacket-stripping facilities of the rocker to cut the cord jacket. When the cord is withdrawn, the jacket is removed from the end portion to expose individually insulated conductors. Then the end portion of the cord is inserted into a modular plug body which has been armed with blade-like terminals (30-30) and the plug inserted into the nest at the other end of the housing.

  • Patent number: 4480374
    Abstract: A tool connects plugs to the ends of communication wires and in particular is used with modular type communication plugs. The tool includes two relatively pivoted handle members that are restrained in the amount that they can be separated and which include a punch that will positively force connector tangs of a plug positioned in a provided receptacle in the tool into the ends of wires of a communication cord to properly and positively connect the individual wires of the cord to the proper terminal of the plug as the handles are squeezed. The tool also has knives which can be used for stripping a specified length from the end of the outer sheath from the insulated wires before inserting the wires into a plug carried in a close fitting receptacle in one of the handle members. The punch has separated lands or bars that separately bear against each contact tang of the plug and in this way force the connecting tang into the individual communication wires.

  • Patent number: 3994652
    Abstract: This invention consists of a combined rolling pin and dough cutter. It is made up mainly of a central shaft provided with a handle at each end, and a series of abutting cylindrical rollers, all of the same diameter, rotate freely upon the central shaft to function as a rolling pin. To perform as a dough cutter, a series of circular cutting discs are inserted between the rollers. These discs are of a larger diameter than the rollers, so that their cutting edge extends beyond said rollers. One handle of the shaft is permanently fixed to the shaft while the other handle unscrews from the shaft to allow the insertion of the rollers and discs. One of the handles of the shaft is bored with a longitudinal hole into which is inserted a center pin which is used for cutting circular sections of dough used in pie making.
