Abstract
Abstract A wire-cutting and insulation-stripping tool is adapted to remove a section of predetermined length from the insulating layer surrounding the conductor of a cable, electrical wire and the like, without damaging the conductor and includes two arms, crossed with each other and articulated to one another in the middle. A spring extends between the arms and is operative for maintaining the arms in an open position. The upper ends of the arms are formed with wire-cutting jaws each provided with a cutting edge sliding over the cutting edge of the other wirecutting jaw. A stripping jaw is mounted on each of said upper ends for displacement thereof, and includes a free end portion extending toward the free end portion of the other stripping jaw and provided with a V-shaped recess cooperating with the recess of the other stripping jaw to sever the wire insulation. An abutment determines the extent of movement of the arms and of the stripping jaws toward one another in dependence on the diameter of the wire to be severed and stripped.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
206 words
A combined wire-cutting and insulation-stripping tool comprising, in combination, a pair of elongated arms having spaced end portions and articulated to one another intermediate said end portions; biasing means extending between said arms and urging the same away from one another; a pair of wire-cutting jaws rigidly connected to the associated end portions of said arms and extending transversely thereto toward one another and adapted to overlap each other, each of said wire-cutting jaws having a cutting edge adapted to cooperate with the cutting edge of the other jaw for engaging and severing a wire introduced therebetween; a pair of stripping jaws connected to said associated end portions and adjustable longitudinally thereof so as to select the distance between said wire-cutting and stripping jaws, each of said stripping jaws having a free end portion extending transversely of the respective arm toward the free end portion of the other stripping jaw and being provided with a Vshaped recess, said V-shaped recesses being adapted to cooperate with one another to sever the insulation of the wire; and an abutment for adjusting the extent of movement of said arms and said stripping jaws toward one another in dependence on the diameter of the wire to be severed and stripped.
Claim 2
Dependent Claim
206 words
A combined wire-cutting and insulation-stripping tool comprising, in combination, a pair of elongated arms having spaced end portions and articulated to one another intermediate said end portions; biasing means extending between said arms and urging the same away from one another; a pair of wire-cutting jaws rigidly connected to the associated end portions of said arms and extending transversely thereto toward one another and adapted to overlap each other, each of said wire-cutting jaws having a cutting edge adapted to cooperate with the cutting edge of the other jaw for engaging and severing a wire introduced therebetween; a pair of stripping jaws connected to said associated end portions and adjustable longitudinally thereof so as to select the distance between said wire-cutting and stripping jaws, each of said stripping jaws having a free end portion extending transversely of the respective arm toward the free end portion of the other stripping jaw and being provided with a Vshaped recess, said V-shaped recesses being adapted to cooperate with one another to sever the insulation of the wire; and an abutment for adjusting the extent of movement of said arms and said stripping jaws toward one another in dependence on the diameter of the wire to be severed and stripped.
Claim 3
Dependent Claim
84 words
A tool as defined in claim 1, each of said stripping jaws further comprising an elongated portion contacting one side of the respective one of said associated end portions and provided with a longitudinally extending slot; and further comprising a threaded projection connected to said one side and extending transversely of said respective end portion and into said slot; and a nut threaded on said projection and adapted to engage said elongated portion so as to retain said stripping jaw in a predetermined position.
Claim 4
Dependent Claim
52 words
A tool as defined in claim 1, each of said stripping jaws further comprising an elongated portion contacting one side of the respective one of said associated end portions, and a pair of lugs projecting from said elongated portion for restraining said stripping jaw to movement longitudinally of said one end portion.
Claim 5
Dependent Claim
28 words
A tool as defined in claim 1, and further comprising a sheath of insulating material at least partially surrounding each of the other end portions of said arms.
Claim 6
Dependent Claim
29 words
A tool as defined in claim 1, wherein said abutment comprises a screw threadedly connected to one of said arms and having a portion extending toward the other arm.
Claim 7
Dependent Claim
33 words
A tool as defined in claim 5, wherein said biasing means includes a spring having one end portion surrounding said portion of said screw and another end portion abutting against said other arm.
