Abstract
Abstract A tool is disclosed for stripping the insulation jacket from a cable, such as the electrical cable used in house wiring, and preparing the conductors for termination. The tool includes portions for slitting the cable, cutting off the slit jacket, stripping measured lengths of the conductors and stripping greater lengths of the conductors. It also includes wire ganging holes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
170 words
A tool for preparing ends of housewiring cable for termination, said tool comprising: a unitary, elongated metal member folded upon itself to form a lower cutter portion and an upper backup portion; a series of gauging apertures formed in one of said lower or upper portions; a cutting blade formed in each said portion extending inwardly towards the opposite portion, said blades being transverse to the elongated dimension of said tool and being offset from each other sufficiently to be out of engagement; a first abutment upwardly turned along one marginal edge of said lower cutter portion, said abutment having a sharpened free edge; and at least one stripper portion upwardly turned along an opposite marginal edge of said lower cutter portion, said at least one stripper portion having at least one arcuate cutting surface in a free edge thereof, whereby insulation jacketing of said cable is slit by said blades and cut off by said abutment and insulation on individual conductors of said cable is stripped by said stripper.
Claim 2
Dependent Claim
170 words
A tool for preparing ends of housewiring cable for termination, said tool comprising: a unitary, elongated metal member folded upon itself to form a lower cutter portion and an upper backup portion; a series of gauging apertures formed in one of said lower or upper portions; a cutting blade formed in each said portion extending inwardly towards the opposite portion, said blades being transverse to the elongated dimension of said tool and being offset from each other sufficiently to be out of engagement; a first abutment upwardly turned along one marginal edge of said lower cutter portion, said abutment having a sharpened free edge; and at least one stripper portion upwardly turned along an opposite marginal edge of said lower cutter portion, said at least one stripper portion having at least one arcuate cutting surface in a free edge thereof, whereby insulation jacketing of said cable is slit by said blades and cut off by said abutment and insulation on individual conductors of said cable is stripped by said stripper.
Claim 3
Dependent Claim
23 words
A tool according to claim 1 wherein said elongated metal member is spring steel having a thickness in the range of 0.030"to 0.050".
Claim 4
Dependent Claim
29 words
A tool according to claim 1 wherein: said cutting blades are offset a distance substantially equal to the diameter of a ground wire found in conventional housewiring electrical cable.
Claim 5
Dependent Claim
36 words
A tool according to claim 1 further comprising: two said stripper portions on said opposite marginal edge, said stripper portions being spaced apart uniformly with respect to said blades defining a cable guide for said blades.
Claim 6
Dependent Claim
27 words
A tool according to claim 4 wherein said abutment lies opposite one of said stripper portions limiting the length of insulation stripped from a wire placed therebetween.
Claim 7
Dependent Claim
35 words
A tool according to claim 4 further comprising: a second abutment on said first marginal edge, said abutments being aligned with said stripper portions to define a cable guide on both sides of said tool.
