Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
A tool for cutting, stripping and wrapping wires comprising, first drive means for a wire wrapping movement and second drive means for a wire insulation stripping movement positioned along a central axis of said tool, a wrapper sleeve coupled for rotary movement to said first drive means, a wrapper pin disposed in said sleeve for axial movement by said second drive means, a lever knife pivotally mounted on said sleeve and having a cutting edge disposed at the forward end to contact the wire insulation upon axial displacement of the wrapper pin, a projection on the other end of said knife in sliding engaGement with said pin, and means on said pin to engage said projection and pivot said cutting edge, said axial movement of said pin stripping and positioning the wire for a wrapping movement.
Claim 2
Dependent Claim
136 words
A tool for cutting, stripping and wrapping wires comprising, first drive means for a wire wrapping movement and second drive means for a wire insulation stripping movement positioned along a central axis of said tool, a wrapper sleeve coupled for rotary movement to said first drive means, a wrapper pin disposed in said sleeve for axial movement by said second drive means, a lever knife pivotally mounted on said sleeve and having a cutting edge disposed at the forward end to contact the wire insulation upon axial displacement of the wrapper pin, a projection on the other end of said knife in sliding engaGement with said pin, and means on said pin to engage said projection and pivot said cutting edge, said axial movement of said pin stripping and positioning the wire for a wrapping movement.
Claim 3
Dependent Claim
38 words
The device of claim 1 including a flat type spiral spring disposed along said axis around said sleeve and having one end coupled to said sleeve to return said sleeve to a normal position after the wrapping movement.
Claim 4
Dependent Claim
27 words
The device of claim 1 including manually operable actuating means positioned one inside the other for operation of said first and second drive means by one finger.
Claim 5
Dependent Claim
27 words
The device of claim 1 including cutting means attached to an outer surface of said tool for cutting wire inserted into said tool to a desired length.
Claim 6
Dependent Claim
17 words
The device of claim 1 including air control means for actuating said first and second drive means.
Claim 7
Dependent Claim
67 words
The device of claim 1 wherein said pin includes an extending portion positioned at the forward end between said pin and sleeve below said wire opposite said cutting edge to cooperate with said edge and tear the wire insulation from both sides, and the other end of said pin having a portion of increasing diameter over that of the forward end to pivot said knife cutting edge.
