Abstract

Abstract Apparatus for stripping insulation from the end portions of the wires of a twisted pair of wires has insulation stripping blades for cutting into the insulation of the wires. A pair of wire orienting members, mounted adjacent to the stripping blades, engage the twisted pair prior to cutting of the insulation and orient the pair properly with respect to the cutting edges. The stripping blades and the orienting fingers are mounted in a rotatable head which untwists the end portions of the twisted pair.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 205 words
A wire stripping device for stripping insulation from the ends of at least two wires, said wires being in side-by-side relationship, said apparatus comprising: a pair of insulation stripping blades, said blades being movable along predetermined paths between open and closed positions, blade moving means for moving said blades along said paths, said blades having opposed edges which are adjacent to, and spaced from each other when said blades are in said closed positions, a plurality of insulation cutting edge means on each of said opposed edges for cutting into the insulation of wires extending between said edges and transversely of said path, wire orienting means mounted beside each of said blades and on each side of said path, said wire orienting means being movable in opposite directions transversely of the axes of said wires during movement of said blades to said closed position whereby, upon locating said wires between said blades when said blades are in said open position and upon movement of said blades towards each other, said orienting means will move in opposite directions towards and past said wires, and said wires will be oriented between said blades in side-by-side relationship with each wire between a cooperating pair of said cutting edges.
Claim 2
Dependent Claim 205 words
A wire stripping device for stripping insulation from the ends of at least two wires, said wires being in side-by-side relationship, said apparatus comprising: a pair of insulation stripping blades, said blades being movable along predetermined paths between open and closed positions, blade moving means for moving said blades along said paths, said blades having opposed edges which are adjacent to, and spaced from each other when said blades are in said closed positions, a plurality of insulation cutting edge means on each of said opposed edges for cutting into the insulation of wires extending between said edges and transversely of said path, wire orienting means mounted beside each of said blades and on each side of said path, said wire orienting means being movable in opposite directions transversely of the axes of said wires during movement of said blades to said closed position whereby, upon locating said wires between said blades when said blades are in said open position and upon movement of said blades towards each other, said orienting means will move in opposite directions towards and past said wires, and said wires will be oriented between said blades in side-by-side relationship with each wire between a cooperating pair of said cutting edges.
Claim 3
Dependent Claim 64 words
A stripping device as set forth in claim 1, said blade moving means comprising opposed slide members, said blades being mounted on said slide members, said wire orienting means being mounted beside said slide members, and camming means on said slide members, said camming means being engageable with said orienting means during movement said slide members towards each other to actuate said orienting means.
Claim 4
Dependent Claim 36 words
A stripping device as set forth in claim 2, each of said wire orienting means comprising a bell crank, each of said camming means comprising a pin engageable with edge portions of its associated bell crank.
Claim 5
Dependent Claim 244 words
A wire stripping device for stripping insulation from each wire of a twisted pair of wires, said device comprising a pair of opposed insulation stripping blades, said blades beinG normally spaced apart and being movable along a predetermined path towards and away from each other between open and closed positions, said blades having opposed wire engaging edges and having insulation cutting edges on said opposed edges, said cutting edges being adapted to cut into the insulation of a wire positioned with its axis extending between said blades and transversely of said path, a pair of opposed twisted pair orienting members, said orienting members being adjacent to, and in alignment with, said stripping blades, said orienting members having surface portions which are movable in opposite directions transversely of said wire positioned between said blades, and actuating means responsive to movement of said blades from said open position to said closed position for moving said surface portions in said opposite directions whereby, during movement of said blades to said closed positions, said surface portions of said orienting members engage said twisted pair which is positioned between said blades and orient said pair with the individual wires thereof in side-by-side relationship with respect to said predetermined path so that said insulation cutting edges of said blades will cut into the insulation of both of said wires, and said twisted pair can thereafter be pulled from between said blades to strip insulation from the ends of said wires.
Claim 6
Dependent Claim 244 words
A wire stripping device for stripping insulation from each wire of a twisted pair of wires, said device comprising a pair of opposed insulation stripping blades, said blades beinG normally spaced apart and being movable along a predetermined path towards and away from each other between open and closed positions, said blades having opposed wire engaging edges and having insulation cutting edges on said opposed edges, said cutting edges being adapted to cut into the insulation of a wire positioned with its axis extending between said blades and transversely of said path, a pair of opposed twisted pair orienting members, said orienting members being adjacent to, and in alignment with, said stripping blades, said orienting members having surface portions which are movable in opposite directions transversely of said wire positioned between said blades, and actuating means responsive to movement of said blades from said open position to said closed position for moving said surface portions in said opposite directions whereby, during movement of said blades to said closed positions, said surface portions of said orienting members engage said twisted pair which is positioned between said blades and orient said pair with the individual wires thereof in side-by-side relationship with respect to said predetermined path so that said insulation cutting edges of said blades will cut into the insulation of both of said wires, and said twisted pair can thereafter be pulled from between said blades to strip insulation from the ends of said wires.
Claim 7
Dependent Claim 20 words
A device as set forth in claim 4, said orienting members comprising bell cranks, said actuating means comprising camming pins.
Claim 8
Dependent Claim 24 words
Apparatus as set forth in claim 4 including clamping means adjacent to said frame means on one side thereof for clamping said twisted pair.
