Abstract
Abstract A mechanism employed for cutting and stripping a plurality of wires simultaneously by means of a single lever which is moved in a first direction to cut the plurality of wires and in a second direction to strip a length of insulation from the cut wires. The mechanism includes a base support and a carriage pivotally mounted thereto. The carriage supports the wire knife and anvil, the stripper knives, a cam arrangement for actuating the wire knife and stripper knives and the control lever. An automatic lock is provided which prevents the carriage from pivotting to strip the wires when the cutting operation is being performed and also prevents return of the wire knife and stripper knife when the stripping operation is being carried out. The mechanism is employed in this embodiment with wire positioning and clamping means. An assembly is used to stress the clamping means to insure the retention of the wires held therein.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
120 words
A multi-wire, cutter-stripper mechanism for cutting and stripping a plurality of wires simultaneoUsly, comprising a base support; knife means for cutting the plurality of wires; stripper means for stripping a section of insulation from the plurality of wires; a carriage pivotally mounted to said base support and carrying said knife means and said stripper means, said carriage being capable of moving relative to said base such that the stripper means will draw the insulation from the wires; and lever means operably associated with said knife means and said stripper means to actuate said knife and said stripper means when moved in a first direction and mounted on said carriage to pivot said carriage when moved in a second, different direction.
Claim 2
Dependent Claim
120 words
A multi-wire, cutter-stripper mechanism for cutting and stripping a plurality of wires simultaneoUsly, comprising a base support; knife means for cutting the plurality of wires; stripper means for stripping a section of insulation from the plurality of wires; a carriage pivotally mounted to said base support and carrying said knife means and said stripper means, said carriage being capable of moving relative to said base such that the stripper means will draw the insulation from the wires; and lever means operably associated with said knife means and said stripper means to actuate said knife and said stripper means when moved in a first direction and mounted on said carriage to pivot said carriage when moved in a second, different direction.
Claim 3
Dependent Claim
26 words
The multi-wire, cutter-stripper mechanism of claim 1 wherein said mechanism further comprises means for clamping and positioning the plurality of wires for cutting and stripping thereof.
Claim 4
Dependent Claim
26 words
The multi-wire, cutter-stripper mechanism of claim 2, wherein said means for positioning and holding the plurality of wires includes an identification block and a wire clamp.
Claim 5
Dependent Claim
27 words
The multi-wire, cutter-stripper mechanism of claim 1 wherein said knife means includes a cutter blade cooperating with said carriage to cut said wires in a straight line.
Claim 6
Dependent Claim
38 words
The multi-wire, cutter-stripper mechanism of claim 1 wherein said stripper means includes a movable stripper knife operably mounted to said carriage so as to move with said knife means and a fixed stripper knife fixed to said carriage.
Claim 7
Dependent Claim
52 words
The multi-wire, cutter-stripper mechanism of claim 5 wherein said movable stripper knife and said fixed stripper knife may be brought into parallel association with one another such that a controlled space exists between the edges of said knifes, said space being determined by the limits on the movement of the lever means.
Claim 8
Dependent Claim
29 words
The multi-wire, cutter-stripper mechanism of claim 6 wherein said lever means may be adjusted to alter the operable association therebetween to vary the controlled spacing of the stripper means.
Claim 9
Dependent Claim
52 words
The multi-wire, cutter-stripper mechanism of claim 1 wherein said mechanism further comprises locking means for preventing the stripping of the plurality of wires during the cutting of the plurality of wires and for preventing the actuation of said knife means and said stripper means during the stripping of the plurality of wires.
Claim 10
Dependent Claim
89 words
The multi-wire cutter-stripper mechanism of claim 8 wherein said locking means includes a stripper latch pivotally mounted to said carriage, a stop provided on said stripper latch and a latch track fixed to said base support, said latch being positionable in a first mode to engage the end of said latch track for preventing pivotal motion of said carriage and being positionable in a second mode such that said stop may ride along the surface of said latch track, said latch track thereby preventing rotation of said stripper latch.
Claim 11
Dependent Claim
36 words
The multi-wire, cutter-stripper mechanism of claim 9 wherein said stripper latch includes a notch for receiving said lever means, said lever means being held by said stripper latch with said stripper latch in said second mode.
Claim 12
Dependent Claim
83 words
The multi-wire, cutter-stripper mechanism of claim 1 wherein said lever means includes a cam actuation means for actuating said knife means and said stripper means, said cam actuation means including a plurality of cams pivotally mounted to said carriage and constrained to rotate with said lever means, said cams operating to force said knife means and said stripper means along said carriage to cut a plurality of wires and position said stripper means for the stripping of insulation from the plurality of wires.
Claim 13
Dependent Claim
35 words
The multi-wire, cutter-stripper mechanism of claim 11 wherein said lever means is adjustable relative to said cam actuation means in order that said stripper means may be adjusted to accommodate a range of wire gauges.
Claim 14
Dependent Claim
92 words
The multi-wire, cutter-stripper mechanism of claim 1 wherein said carriage includes a carriage plate pivotally mounted to said base support, said plate having a substantially Rectangular hole located therethrough, said knife means including a cutter blade positioned on one side of said carriage plate and said stripper means including a movable stripper knife positioned on the other side of said carriage plate, said movable stripper knife and said cutter blade being held to either side of said carriage plate by fasteners extending therebetween through said substantially rectangular hole in said carriage plate.
Claim 15
Dependent Claim
45 words
The multi-wire, cutter-stripper mechanism of claim 1 wherein said lever means is rotated relative to said carriage to cut the plurality of wires and is moved with said carriage pivotally about said base support to strip a length of insulation from the plurality of wires.
