Abstract
Abstract A plier-like tool for stripping insulaton from sheathed cables or wires has an elongate body terminating at a front end in a first gripping jaw and at a rear end in a first shank toward which a second shank, forming part of a handle pivoted to the body, is movable to clamp the end of a cable between the first gripping jaw and a coacting second gripping jaw also pivoted to the body. The second gripping jaw is controlled by the handle via a camming mechanism which also displaces a link member along the body, that link member being rigid with a first stripping jaw and being articulated to a second stripping jaw and being articulated of the two gripping jaws for pulling insulation off the clamped cable end. The rear end of the link member, remote from the stripping jaws, is positively guided in a rib of the body and is slidably connected with a guide member resting against an overhanging shelf of the body provided with a detent formation, the sliding connection between the link and guide members including a slot extending parallel to the shelf and to a guide track of the first gripping jaw along which the first stripping jaw slides; the subassembly of guide member, link member and stripping jaws can thus be positively secured to the tool body without riveting or other fastening operations. A front edge of the guide member defines with an upper edge of the link member and with a rear edge of an upward projection thereof an upwardly open recess which is narrowed upon a rearward sliding of the link member, at least one of these edges being sharpened for cutting into the insulation of a cable inserted into that recess.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
361 words
A tool for handling slender workpieces, comprising: an elongate body provided at a front end thereof with a first gripping jaw and terminating at a rear end thereof in a first shank; a second gripping jaw swingably mounted on said body, said gripping jaws being respectively provided with confronting first and second guide tracks extending rearwardly from a pair of cable-clamping extensions; a first stripping jaw slidable along said first guide track; a second stripping jaw articulated to said first stripping jaw and slidable along said second guide track; a link member with a front portion, an intermediate portion and a rear portion slidable along said body in a longitudinal direction generally parallel to said first guide track, said front portion being positively coupled with said stripping jaws, said first shank being provided with restraining means engaging said rear portion for preventing lateral excursions thereof in the swing plane of said second gripping jaw; a handle pivotally mounted on said body, said handle forming a second shank alongside said first shank and being operatively connected with said second gripping jaw and with said link member for moving said extensions toward each other and rearwardly retracting said stripping jaws and said link member upon being swung toward said first shank; and a guide member detachably secured to said body close to said intermediate portion and coupled by coacting formations with said link member for joint removal from said body together with said stripping jaws, said formations enabling relative displacement of said members in said longitudinal direction while preventing such displacement in a direction transverse to said swing plane, said body being provided with abutment means engaging said guide member and preventing any relative displacement thereof, said intermediate portion having a projection provided with a rearwardly facing land confronting a forwardly facing land of said guide member across a laterally open recess narrowing upon rearward movement of said link member under the control of said handle, said recess being further bounded by a lateral land extending generally in said longitudinal direction, at least one of said lands having a cutting edge for biting into the insulation of a cable inserted into said recess.
Claim 2
Dependent Claim
361 words
A tool for handling slender workpieces, comprising: an elongate body provided at a front end thereof with a first gripping jaw and terminating at a rear end thereof in a first shank; a second gripping jaw swingably mounted on said body, said gripping jaws being respectively provided with confronting first and second guide tracks extending rearwardly from a pair of cable-clamping extensions; a first stripping jaw slidable along said first guide track; a second stripping jaw articulated to said first stripping jaw and slidable along said second guide track; a link member with a front portion, an intermediate portion and a rear portion slidable along said body in a longitudinal direction generally parallel to said first guide track, said front portion being positively coupled with said stripping jaws, said first shank being provided with restraining means engaging said rear portion for preventing lateral excursions thereof in the swing plane of said second gripping jaw; a handle pivotally mounted on said body, said handle forming a second shank alongside said first shank and being operatively connected with said second gripping jaw and with said link member for moving said extensions toward each other and rearwardly retracting said stripping jaws and said link member upon being swung toward said first shank; and a guide member detachably secured to said body close to said intermediate portion and coupled by coacting formations with said link member for joint removal from said body together with said stripping jaws, said formations enabling relative displacement of said members in said longitudinal direction while preventing such displacement in a direction transverse to said swing plane, said body being provided with abutment means engaging said guide member and preventing any relative displacement thereof, said intermediate portion having a projection provided with a rearwardly facing land confronting a forwardly facing land of said guide member across a laterally open recess narrowing upon rearward movement of said link member under the control of said handle, said recess being further bounded by a lateral land extending generally in said longitudinal direction, at least one of said lands having a cutting edge for biting into the insulation of a cable inserted into said recess.
Claim 3
Dependent Claim
36 words
A tool as defined in claim 1 wherein said formations are a slot extending in said longitudinal direction on one of said members and a pin on the other of said members received in said slot.
Claim 4
Dependent Claim
22 words
A tool as defined in claim 1 wherein one of said members has a bight portion embracing the other of said members.
Claim 5
Dependent Claim
19 words
A tool as defined in claim 1 wherein said confronting lands converge toward the open side of said recess.
Claim 6
Dependent Claim
34 words
A tool as defined in claim 1 wherein at least one of said confronting lands has a generally V-shaped cutting edge with the vertex of the V pointing away from the other confronting land.
Claim 7
Dependent Claim
35 words
A tool as defined in claim 1 wherein said forwardly facing land includes an acute angle with said longitudinal direction and with said lateral land, said rearwardly facing land being devoid of any cutting edge.
Claim 8
Dependent Claim
24 words
A tool as defined in claim 1 wherein said abutment means forms a detent resiliently coacting with a mating formation on said guide member.
Claim 9
Dependent Claim
20 words
A tool as defined in claim 1 wherein said link member forms an integral unit with said first stripping jaw.
Claim 10
Dependent Claim
26 words
A tool as defined in claim 1 wherein said members and said stripping jaws consist of a material of higher strength than that of said body.
Claim 11
Dependent Claim
34 words
A tool as defined in claim 9 wherein said material of higher strength is sheet steel, the material of said body being selected from the group which consists of light-metal allows and synthetic resins.
