Abstract
A tool for cutting electrical wire and stripping a length of electrical insulating material away from the electrically conducting core is provided with an enlarged head on each jaw so that a plurality of exposed electrically conducting cores may be grasped between the heads and twisted around a longitudinally extending axis.
Claims4
A tool capable of use in the cutting, stripping and twisting of electric wire having an electrically conducting core surrounded by electrical insulating material comprising:
- at least two members;
- pivot means for pivotally joining said at least two members together so as to form two handles on one side of said pivot means and two extensions on the other side of said pivot means so that said at least two members can be moved to an opened or a closed relationship;
- each of said extensions terminating in a jaw;
- each of said jaws having a gripping surface facing each other;
- an elongated portion on each of said extensions located between each of said jaws and said pivot means;
- each of said elongated portions having a length, a width and a thickness wherein said length is greater than said width and said with is greater than said thickness;
- each of said elongated portions having a planar surface extending in a widthwise direction so that said planar surfaces are in parallel relationship;
- a linear cutting edge on each of said planar surfaces;
- a plurality of semicircular cutting edges of different diameters spaced apart in a lengthwise direction in each of said planar surfaces so as to form a plurality of circular cutting edges of different diameters when said at least two members are moved toward a closed relationship;
- each of said jaws having a length, a width and a thickness in directions corresponding to said length, said width and said thickness of each of said elongated portions;
- and
- said thickness of each of said jaws being substantially greater than said thickness of each of said elongated portions so that the ends of at least two stripped electric wires may be readily grasped and twisted with the longitudinal axis of the tool parallel to the longitudinal axes of said at least two stripped electric wires.
