Wire stripping tools

Claim 1

A tool for stripping the sheath from a wire cable, comprising, in combination, a pair of jaws for receiving the cable therebetween in a predetermined position, each jaw comprising a stack of laminae, the individual laminae of each stack being positioned for face-to-face contact, each lamina having a cutting projection, all of the cutting projections located in a common plane which is normal to the axis of the wire when received between said jaws in said predetermined position, means for closing said jaws together for the projections to cut into the cable, and resilient means for acting on each stack of laminae permitting relative movement of the individual laminae sufficiently that said laminae are conformable to a cross section of a cable to be stripped and the projections penetrate through a sheath around said cable''s periphery, means for moving said pair of jaws axially along said cable''s length, and additional jaws for grasping said cable and for holding said cable in a substantially stationary position during said pair''s axial movement.

Claim 5

A device for stripping the sheath from a wire, comprising, in combination, a first blade means having a first inwardly directed cutting edge; clamping means comprising opposing jaw means including a pivoted jaw and an opposite jaw for grasping a sheathed wire therebetween and for imparting to said edge a sheath stripping movement axially along said wire, said clamping means including a handle means for reciprocating movement of said pivoted jaw toward and away from said opposite jaw responsive to reciprocating movement of said handle means and for imparting said axial movement between opposite movements of the reciprocating movement of said pivoted jaw, an extension of said opposite jaw extending axially toward said handle means, said pivoted jaw also extending axially toward the extension of the opposite jaw and pivotally mounted on said extension, and a shaft means extending axially to said extension; said first blade means being pivotally attached to said shaft means and being mounted between said pivoted jaw and said opposite jaw with one of said jaws abutting a noncutting edge of said first blade means sufficiently to urge forward said cutting edge toward the other jaw, and said first cutting edge extending substantially parallel to said axial movement and extending between about said pivoted jaw and said handle means; said shaft means being mounted on at least one of said jaws for said axial movement along the extension of the opposite jaw sufficiently for imparting to said axial movement of said first blade means to-and-fro axial directions relative to said jaw means, said to-and-fro movement being responsive to said reciprocating movement of the handle means; spring means mounted to act against an abutment on said shaft means and oppositely against said clamping means for resisting said axial movement of said first blade means and for returning said first blade means to an extended position; said clamping means further including a toggle lever, a first lever of said toggle lever being pivotally mounted on said handle means at about the distal end of the first lever, a second lever of the toggle lever at about the distal end of the second lever being pivotally mounted on the extension of the opposite jaw, and a third lever of said toggle lever at about the distal end of the third lever being pivotally mounted on said pivoted jaw; a second blade means having a second cutting edge about parallel to the first cutting edge, said second blade means being pivotally mounted whereby the second cutting edge is urged toward the first cutting edge by the other jaw when the first cutting edge is urged forward; a resilient spring means mounted against the opposing first and second cutting edges for resisting movement of the edges toward each other and for returning the edges to an open-jaw position; an adjustable pressure means mounted on at least one of the jaws for regulating and determining the relative distance of one of the blade means from an abutting jaw; and at least one of said blade means including a plurality of blades having cutting edges in substantially parallel relationship to one another, a substantially horizontal cutting edge and another substantially vertical cutting edge relative to the axial extension of the jaw, said first and second cutting edges extending in a direction substantially parallel to the axial extension of the jaw.

Claim 6

A device for stripping the sheath from a wire, comprising, in combination, a first blade means having a first inwardly directed cutting edge; clamping means comprising opposing jaw means including a pivoted jaw and an opposite jaw for grasping a sheathed wire therebetween and for imparting to said edge a sheath stripping movement axially along said wire, said clamping means including a handle means for reciprocating movement of said pivoted jaw toward and away from said opposite jaw responsive to reciprocating movement of said handle means and for imparting said axial movement between opposite movements of the reciprocating movement of said pivoted jaw, an extension of said opposite jaw extending axially toward said handle means, said pivoted jaw also extending axially toward the extension of the opposite jaw and pivotally mounted on said extension, and a shaft means extending axially to said extension; said first blade means being pivotally attached to said shaft means and being mounted between said pivoted jaw and said opposite jaw with one of said jaws abutting a noncutting edge of said first blade means sufficiently to urge forward said cutting edge toward the other jaw, and said first cutting edge extending substantially parallel to said axial movement and extending between about said pivoted jaw and said handle means; said shaft means being mounted on at least one of said jaws for said axial movement along the extension of the opposite jaw sufficiently for imparting to said axial movement of said first blade means to-and-fro axial directions relative to said jaw means, said to-and-fro movement being responsive to said reciprocating movement of the handle means; spring means mounted to act against an abutment on said shaft means and oppositely against said clamping means for resisting said axial movement of said first blade means and for returning said first blade means to an extended position; said clamping means further including a toggle lever, a first lever of said toggle lever being pivotally mounted on said handle means at about the distal end of the first lever, a second lever of the toggle lever at about the distal end of the second lever being pivotally mounted on the extension of the opposite jaw, and a third lever of said toggle lever at about the distal end of the third lever being pivotally mounted on said pivoted jaw; a second blade means having a second cutting edge about parallel to the first cutting edge, said second blade means being pivotally mounted whereby the second cutting edge is urged toward the first cutting edge by the other jaw when the first cutting edge is urged forward; a resilient spring means mounted against the opposing first and second cutting edges for resisting movement of the edges toward each other and for returning the edges to an open-jaw position; an adjustable pressure means mounted on at least one of the jaws for regulating and determining the relative distance of one of the blade means from an abutting jaw; and at least one of said blade means including a plurality of blades having cutting edges in substantially parallel relationship to one another, a substantially horizontal cutting edge and another substantially vertical cutting edge relative to the axial extension of the jaw, said first and second cutting edges extending in a direction substantially parallel to the axial extension of the jaw.
