Abstract
Abstract A wire stripping tool is provided which is capable of stripping a predetermined depth and length of insulation from the end of various size insulated wires. A generally U-shaped frame member has the free ends of its leg portions bent inwardly into parallel overlapping relationship with each other to form reciprocating stripping jaws. Each of these reciprocating stripping jaws has a mating V-shaped cutting edge formed therein which cooperate to form an adjustable wire receiving aperture therebetween. A pair of telescoping spacer members are positioned between the legs of the frame member and adjustable laterally to control the amount of movement of the cutting edges toward one another for regulation of the depth of the wire insulation being removed. The telescoping spacer members, which serve as a stop for the wire to be stripped, are also adjustably mounted for longitudinal movement relative to the legs of the frame member and the stripping jaws for regulation of the length of insulation that is to be removed from the wire. This tool incorporates easy-to-read numerical gauges to facilitate accurate adjustment for the desired length and size (diameter) of wire that is to be stripped.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
294 words
A wire stripping device for stripping a predetermined length and depth of insulation from an insulated wire comprising, in combination: a frame member including a pair of leg portions connected at one end and having their free ends bent inwardly into parallel overlapping relationship to form reciprocating stripping jaws, said leg portions each having a longitUdinally-extending slot formed therein, each of said reciprocating stripping jaws having a mating cutting edge formed therein, said cutting edges cooperating to form a wire-receiving aperture therebetween; and an adjustment mechanism slidably mounted to and between said leg portions of said frame means, said adjustment mechanism including first and second spacer members positioned between said leg portions of said frame member, first and second slide plates positioned in overlying relationship to said leg portions and having apertures formed therein, and first and second threaded adjustment bolts, said first bolt being inserted inwardly through the aperture in said first slide plate and through the slot in said one of said leg portions into threaded engagement with said first spacer member to adjust the position of said adjustment mechanism relative to said reciprocating stripping jaws to thereby control the distance of insertion of the insulated wire through said wirereceiving aperture and regulate the length of insulation to be stripped from said insulated wire, and said second bolt being inserted inwardly through the aperture in said second slide plate and through the slot in the other of said leg portions into threaded engagement with said second spacer member and being rotatable to adjust the position of said second spacer member relative to said first spacer member to control the travel of the reciprocating stripping jaws towards one another to thereby regulate the depth of insulation to be stripped from said insulated wire.
Claim 2
Dependent Claim
294 words
A wire stripping device for stripping a predetermined length and depth of insulation from an insulated wire comprising, in combination: a frame member including a pair of leg portions connected at one end and having their free ends bent inwardly into parallel overlapping relationship to form reciprocating stripping jaws, said leg portions each having a longitUdinally-extending slot formed therein, each of said reciprocating stripping jaws having a mating cutting edge formed therein, said cutting edges cooperating to form a wire-receiving aperture therebetween; and an adjustment mechanism slidably mounted to and between said leg portions of said frame means, said adjustment mechanism including first and second spacer members positioned between said leg portions of said frame member, first and second slide plates positioned in overlying relationship to said leg portions and having apertures formed therein, and first and second threaded adjustment bolts, said first bolt being inserted inwardly through the aperture in said first slide plate and through the slot in said one of said leg portions into threaded engagement with said first spacer member to adjust the position of said adjustment mechanism relative to said reciprocating stripping jaws to thereby control the distance of insertion of the insulated wire through said wirereceiving aperture and regulate the length of insulation to be stripped from said insulated wire, and said second bolt being inserted inwardly through the aperture in said second slide plate and through the slot in the other of said leg portions into threaded engagement with said second spacer member and being rotatable to adjust the position of said second spacer member relative to said first spacer member to control the travel of the reciprocating stripping jaws towards one another to thereby regulate the depth of insulation to be stripped from said insulated wire.
Claim 3
Dependent Claim
32 words
A wire stripping device as set forth in claim 1 wherein said first and second threaded adjustment bolts each include a threaded shaft portion and a grasping knob at one end thereof.
Claim 4
Dependent Claim
38 words
A wire stripping device as set forth in claim 2 wherein said adjustment mechanism further includes a retaining ring which snaps into a notch in said second bolt on the inside of the other of said leg portions.
Claim 5
Dependent Claim
52 words
A wire stripping device as set forth in claim 3 wherein said one of said leg portions has distance markings thereon indicating the distance from said stripping jaws for easy adjustment of the position of said adjustment mechanism to correspond with desired lengths of insulation to be stripped from an insulated wire.
Claim 6
Dependent Claim
34 words
A wire stripping device as set forth in claim 4 wherein said second slide plate has wire gauge markings thereon indicating various rotational positions of said second bolt which corresponds to various wire gauges.
Claim 7
Dependent Claim
39 words
A wire stripping device as set forth in claim 1 wherein said first and second spacer members are of mating rectangular cross-section and sized so that one of said spacer members telescopes within the other of said spacer members.
