Abstract
Abstract Mechanism for cutting insulated wire such as electrical wire and then stripping both ends of the cut wire adjacent the cut. The mechanism also has means for then positively removing the waste portions of the insulation from both the upper and lower stripping knives. The upper and lower knock-out fingers for the upper and lower stripping knives, respectively, are connected together by a resiliently loaded, telescoping mechanism. The insulated wire stock is held in a lengthwise fixed position by a pair of gripping jaws; the wire is then cut through by a pair of blade assemblies and simultaneously the insulation only is cut on either side of the main cut; the cut insulation is then stripped from the free end of one of the wires by movement of the blade assemblies and the cut insulation is stripped from the end of the other wire by movement of one pair of gripping jaws relative to the blade assemblies. The double knock-out means is then operative to wipe both of the cooperating insulation cutting blade assemblies free of the stripped insulation material.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
An insulated wire cutting and stripping mechanism comprising a support frame, a stationary tool support and a reciprocable tool support, both supports operatively mounted on said frame and in opposed relation to each other; a pair of relatively opposed wire clamping jaws mounted, respectively, on said tool supports; a pair of relatively opposed wire and insulation cutting blade assemblies mounted, respectively, on said tool supports in laterally shiftable relation to said clamping jaws; a pair of relatively opposed cut wire gripping jaws mounted, respectively on said tool supports in laterally shiftable relation to said cutting blade assemblies, and cut insulation waste knock-out means operatively associated with both of the tool supports and opposed cutting blade assemblies for removing cut insulation waste material from their respective cutting blade assembly, said knock-out means comprising fingers mounted on their respective tool support for shifting relative to their respective blade assembly, and means connected between and for resiliently urging the fingers of said opposed knife assemblies away from one another, and said blade assemblies move relative to their respective fingers to thereby cause said fingers to remove cut insulation waste material from their blade assemblies.
Claim 2
Dependent Claim
191 words
An insulated wire cutting and stripping mechanism comprising a support frame, a stationary tool support and a reciprocable tool support, both supports operatively mounted on said frame and in opposed relation to each other; a pair of relatively opposed wire clamping jaws mounted, respectively, on said tool supports; a pair of relatively opposed wire and insulation cutting blade assemblies mounted, respectively, on said tool supports in laterally shiftable relation to said clamping jaws; a pair of relatively opposed cut wire gripping jaws mounted, respectively on said tool supports in laterally shiftable relation to said cutting blade assemblies, and cut insulation waste knock-out means operatively associated with both of the tool supports and opposed cutting blade assemblies for removing cut insulation waste material from their respective cutting blade assembly, said knock-out means comprising fingers mounted on their respective tool support for shifting relative to their respective blade assembly, and means connected between and for resiliently urging the fingers of said opposed knife assemblies away from one another, and said blade assemblies move relative to their respective fingers to thereby cause said fingers to remove cut insulation waste material from their blade assemblies.
Claim 3
Dependent Claim
36 words
The mechanism set forth in claim 1 further characterized in that said means connected between the fingers of opposed knife assemblies comprises a telescoping member having a spring for urging said member to an extended position.
Claim 4
Dependent Claim
26 words
The mechanism set forth in claim 2 further characterized in that said telescoping member includes a lost motion connection between the fingers and said telescoping member.
Claim 5
Dependent Claim
37 words
The mechanism set forth in claim 3 further characterized in that said telescoping member is slideably mounted at one end of said stationary tool support and is fixed at the other end to said reciprocable tool support.
Claim 6
Dependent Claim
161 words
Insulated wire cutting and stripping mechanism comprising a stationary tool support and a reciprocable tool support mounted in opposed relation to each other; relatively opposed wire clamping jaws mounted on said tool supports; relatively opposed wire and insulation cutting blade assemblies mounted, respectively, on said tool supports for relative movement between said blade assemblies between a wire cutting position and a wire releasing position, and knock-out means operatively associated with both of the tool supports and opposed cutting blade assemblies for removing cut insulation waste material from their respective cutting blade assembly, said knock-out means comprising fingers mounted on their respective tool support for shifting relative to their respective blade assembly, and means connected between and for urging the fingers of said opposed knife assemblies to move relative to one another, and said blade assemblies move with their respective support and relative to their respective fingers to thereby cause said fingers to remove cut insulation waste material from their blade assemblies.
Claim 7
Dependent Claim
161 words
Insulated wire cutting and stripping mechanism comprising a stationary tool support and a reciprocable tool support mounted in opposed relation to each other; relatively opposed wire clamping jaws mounted on said tool supports; relatively opposed wire and insulation cutting blade assemblies mounted, respectively, on said tool supports for relative movement between said blade assemblies between a wire cutting position and a wire releasing position, and knock-out means operatively associated with both of the tool supports and opposed cutting blade assemblies for removing cut insulation waste material from their respective cutting blade assembly, said knock-out means comprising fingers mounted on their respective tool support for shifting relative to their respective blade assembly, and means connected between and for urging the fingers of said opposed knife assemblies to move relative to one another, and said blade assemblies move with their respective support and relative to their respective fingers to thereby cause said fingers to remove cut insulation waste material from their blade assemblies.
