Abstract
Abstract A tool for selectively removing layers from jacketed wire. The tool incorporates an anvil and cutting head on spring biased lever arms. The cutting head mounts spaced parallel circumferential slitting blades positioned over a first wire guide channel on the anvil and a longitudinal slitting blade positioned over a second wire guide channel on the anvil. The blades are adjustable to regulate the depth of cut. The circumferential slit is made by rotating the tool around the wire with the wire in the first guide channel and then placing the wire in the second guide channel to longitudinally slit and remove the layer over a length corresponding to the spacing between the circumferential slitting blades.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
282 words
A tool for selectively removing layers from jacketed wire, comprising: a cutting head mounting a first circumferential slitting blade on a first face thereof and protruding beyond a second face, and mounting a longitudinal slitting blade on a third face thereof and protruding beyond said second face, a second circumferential slitting blade mounted on a fourth face of said head and protruding beyond said second face, an anvil having at least two longitudinal wire guide channels in a first face thereof, interconnection means mounting said second face of said cutting head and said first face of said anvil in opposed relationship and biasing said anvil and said cutting head toward one another, said first and said second circumferential slitting blades being positioned over, and transversely of, a first of said wire guide channels, and said longitudinal slitting blade being positioned over and aligned with a second of said second wire guide channels, said first and second circumferential slitting blades being parallel to one another and spaced from one another along said first wire guide channel, a first operating lever extending from said cutting head, a second operating lever extending from said anvil generally aligned with and in opposition to said first operating lever, said interconnection means providing a pivot point between the ends of said levers, guide flanges extending from one of said operating levers, said guide flanges being spaced from said pivot point and extending along and in close proximity to the sides of the other of said operating levers limiting the relative movement of said operating levers to pivotal rotation, said first and second circumferential slitting blades and said longitudinal slitting blade being adjustable toward and away from said anvil.
Claim 2
Dependent Claim
282 words
A tool for selectively removing layers from jacketed wire, comprising: a cutting head mounting a first circumferential slitting blade on a first face thereof and protruding beyond a second face, and mounting a longitudinal slitting blade on a third face thereof and protruding beyond said second face, a second circumferential slitting blade mounted on a fourth face of said head and protruding beyond said second face, an anvil having at least two longitudinal wire guide channels in a first face thereof, interconnection means mounting said second face of said cutting head and said first face of said anvil in opposed relationship and biasing said anvil and said cutting head toward one another, said first and said second circumferential slitting blades being positioned over, and transversely of, a first of said wire guide channels, and said longitudinal slitting blade being positioned over and aligned with a second of said second wire guide channels, said first and second circumferential slitting blades being parallel to one another and spaced from one another along said first wire guide channel, a first operating lever extending from said cutting head, a second operating lever extending from said anvil generally aligned with and in opposition to said first operating lever, said interconnection means providing a pivot point between the ends of said levers, guide flanges extending from one of said operating levers, said guide flanges being spaced from said pivot point and extending along and in close proximity to the sides of the other of said operating levers limiting the relative movement of said operating levers to pivotal rotation, said first and second circumferential slitting blades and said longitudinal slitting blade being adjustable toward and away from said anvil.
Claim 3
Dependent Claim
50 words
A tool according to claim 1, wherein: said first and second circumferential slitting blades and said longitudinal slitting blades being positioned in blade guideS comprising planar slots in said first, third and fourth cutting head faces, said blades having a width substantially equal to the width of said planar slots.
Claim 4
Dependent Claim
39 words
A tool according to claim 1, wherein: the length of the cutting edge of said longitudinal slitting blade along said second wire guide channel is substantially equal to the distance between said first and said second circumferential slitting blades.
Claim 5
Dependent Claim
16 words
A tool according to claim 1, wherein: said longitudinal slitting blade has a straight cutting edge.
