Abstract
Abstract A device for precisely and squarely cutting a length of insulation or shielding about a wire preparatory to stripping it from a cable, comprising a body member having a bore into which the cable is inserted and supported, a cutting element secured to a frame bearingly mated to the body member and which is adapted to communicate with such bore, means for biasing the frame and cutter in a direction for the cutter to engage the insulation about the wire, and a micrometer mounted in fixed spaced relationship to the body and which provides in its calibrated adjustment and operation for varying the exact degree or extent of movement or displacement for the frame and cutter as the cutter slices into the insulated cable. The setting of the micrometer limits the extent of movement of the frame and cutter in relation to the body member and its bore. The biasing means is adjustable to effect the desired tension on the material of the insulation. Scale means is provided to determine the length of the cable to be inserted into the body and by which a length of insulation is determined to be cut. The cutter performs a slicing action across the insulation as the device is turned about the cable and in accordance with the tension provided by the adjustable biasing means, to effect a clean and true or square cutting of a layer of insulation or shielding to an exact depth. Adaptors or bushings are provided for the body for supporting a variety of sizes of insulated cables.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
224 words
A device for cutting one or more layers of insulation or the like from a cable comprising, a frame, a body mounted to said frame and including a bore for supporting the cable, said frame and body being rectilinearly slidable relative to each other, means defining openings in said frame and body and oriented perpendicular to and in communication with said bore, a cutting means secured to said frame and mounted in said openings and including a cutting edge in communication with said bore, means mounted between said body and frame for biasing said frame in a direction causing said cutting means to seek its maximum point of penetration in said bore, means mounted in fixed spaced relation to said body for limiting the maximum extent of movement in such direction for said frame and cutting means, whereby upon rectilinear displacement of said frame and cutting means away from said limiting means and against the direction of the biasing of said frame, the cable is insertable into said bore, and upon the return rectilinear movement of said frame in such direction, said cutting edge engages the cable''s layer, after which the relative turning between said device and cable causes a slicing action of said cutting edge through the cable to a depth predetermined by the relative position of said lighting means to said frame.
Claim 2
Independent Claim
224 words
A device for cutting one or more layers of insulation or the like from a cable comprising, a frame, a body mounted to said frame and including a bore for supporting the cable, said frame and body being rectilinearly slidable relative to each other, means defining openings in said frame and body and oriented perpendicular to and in communication with said bore, a cutting means secured to said frame and mounted in said openings and including a cutting edge in communication with said bore, means mounted between said body and frame for biasing said frame in a direction causing said cutting means to seek its maximum point of penetration in said bore, means mounted in fixed spaced relation to said body for limiting the maximum extent of movement in such direction for said frame and cutting means, whereby upon rectilinear displacement of said frame and cutting means away from said limiting means and against the direction of the biasing of said frame, the cable is insertable into said bore, and upon the return rectilinear movement of said frame in such direction, said cutting edge engages the cable''s layer, after which the relative turning between said device and cable causes a slicing action of said cutting edge through the cable to a depth predetermined by the relative position of said lighting means to said frame.
Claim 3
Dependent Claim
34 words
The device of claim 1 in which said limiting means comprises a micrometer, the abutment of said frame against said micrometer corresponding to the maximum extent of movement of said frame in such direction.
Claim 4
Dependent Claim
26 words
The device of claim 1 including scale means for determining the point along the length of the cable at which the cut is to be made.
Claim 5
Dependent Claim
49 words
The device of claim 3 in which said scale means comprises a graduated scale bar adjustable longitudinally of said device, and having means thereon for marking a cable, the marking of such cable and said marking means providing a measurement of a length of the cable to be cut.
Claim 6
Dependent Claim
19 words
The device of claim 1 in which said biasing means comprises a spring mounted between said body and frame.
Claim 7
Dependent Claim
24 words
The device of claim 5 in which said biasing means is adjustable for regulating the tension of said cutting means on an inserted cable.
Claim 8
Dependent Claim
34 words
The device of claim 1 including a bushing for said bore whereby a different sized cable for the device than one sized to the bore is insertable and cuttable by operation of said device.
Claim 9
Dependent Claim
40 words
The device of claim 7 in which said bushing includes a flat, and a second flat is included on said body, both flats mutually cooperating with each other for ensuring alignment of said openings by preventing rotation of said bushing.
Claim 10
Dependent Claim
63 words
The device of claim 1 including a base member secured to said body, said frame being disposed between said base member and handle, an arm mounted on said base member is spaced relation to one side of said frame, said limiting means being fixed to said arm and being cooperatively related to said side of said frame whereby such limiting movement is effected.
Claim 11
Dependent Claim
201 words
A wire stripping device comprising in combination, a body having a bore for supporting a cable having at least one layer of insulation or the like thereon, a slot in said body and oriented perpendicular to the axis of and in communication with said bore, a frame mounted to said body and having an opening therein in alignment with said slot, said frame and body being rectilinearly slidable relative to each other, a cutting means including a cutting edge mounted in said opening and secured to said frame, said cutting edge communicable with said bore through said slot, means for biasing said frame in a rectilinear manner relative to said body so as to cause said cutting edge to seek its maximum point of penetration in said bore, and micrometer means mounted in fixed spaced relation to said body and being cooperatively related to said frame for overcoming the directional effect of said rectilinearly-acting biasing means, whereby adjustment of said micrometer means predetermines the maximum extent of said cutting edge in said bore, and upon insertion of a cable in said bore and operation of said device, said cutting edge severs the insulation or the like thereon to such maximum extent.
Claim 12
Dependent Claim
201 words
A wire stripping device comprising in combination, a body having a bore for supporting a cable having at least one layer of insulation or the like thereon, a slot in said body and oriented perpendicular to the axis of and in communication with said bore, a frame mounted to said body and having an opening therein in alignment with said slot, said frame and body being rectilinearly slidable relative to each other, a cutting means including a cutting edge mounted in said opening and secured to said frame, said cutting edge communicable with said bore through said slot, means for biasing said frame in a rectilinear manner relative to said body so as to cause said cutting edge to seek its maximum point of penetration in said bore, and micrometer means mounted in fixed spaced relation to said body and being cooperatively related to said frame for overcoming the directional effect of said rectilinearly-acting biasing means, whereby adjustment of said micrometer means predetermines the maximum extent of said cutting edge in said bore, and upon insertion of a cable in said bore and operation of said device, said cutting edge severs the insulation or the like thereon to such maximum extent.
