Abstract
A unitary multi-purpose tool cuts, strips and twists together wires for example in preparation for the installation of insulating cap-type twist-on wire connectors.
Claims1
A hand-held wire cutting and twisting tool comprising:
- a. a generally cylindrical handle member;
- b. a head member generally aligned concentrically with the axis of said handle member and spaced therefrom;
- c. a face on said head member in a plane generally normal to the axis of said handle member;
- d. a generally cylindrical shank concentric with said handle member connecting said handle member to said head member;
- e. at least two blind holes normal to said face and parallel to the axis of said handle member, each of said at least two blind holes being symmetrically offset from the axis of said handle member;
- f. each of said at least two blind holes being adapted to the insertion therein of the stripped end of one wire to be twisted;
- g. said at least two blind holes, in combination with said head member, shank and handle member, being operative to twist together the stripped ends of at least two wires inserted therein when the wires are held and the handle member rotated about its axis;
- h. a fixed cutting and stripping blade rigidly attached to said shank;
- i. a moveable cutting and stripping blade pivotally attached at one of its ends in operatively opposed relationship to said fixed cutting and stripping blade;
- j. a handle on the second end of said moveable cutting and stripping blade;
- k. opposed scissors blade means on said fixed and moveable cutting and stripping blades for cutting through said wires;
- and
- l. at least one semicircular stripping notch in each of said fixed and moveable cutting and stripping blades, said stripping notches facing each other and together forming a generally circular hole with a sharpened perimeter, said generally circular hole being slightly larger in diameter than the diameter of a wire conductor to be stripped.
