Abstract
Abstract A plier-like tool for stripping sheathing or insulation from cables and the like has a pair of outer gripping jaws and a pair of stripping jaws longitudinally movable on the inside of the gripping jaws. Compression of handle-like portions of the tool first causes the outer gripping jaws to hold the end of a cable inserted longitudinally into the bite of the gripping jaws, and further compression activates the stripping jaws to cut through the sheathing and then move rearwardly to strip the sheathing from the inserted end of the cable. Cable cutting means can be included in the tool.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
293 words
A tool for stripping the sheathing from sheathed cables comprising: a. a pair of articulated clamping jaws for holding an end of a sheathed cable during stripping operations, a first of said clamping jaws forming one end of an elongated main body to which the second of said clamping jaws is pivotably connected, said pivotable clamping jaw having a portion extending backwardly from the pivot point and provided at its rear extremity with a cam surface; b. a pair of longitudinally movable, articulated stripping jaws adjacent the inner sides of the clamping jaws, said stripping jaws having cutting edges for cutting into the sheathing and for stripping said sheathing from the cable; c. pulling means on said elongated main body connected to the stripping jaws for pulling said stripping jaws in a direction longitudinal to a cable held in the clamping jaws; and d. means for operating said clamping jaws and stripping jaws comprising: i. an elongated member pivotably connected by one end thereof to the elongated main body and extending longitudinally backward away from the clamping jaws; ii. a biased driving arm pivoted at one end thereof to said elongated member, the free end of said driving arm engaging the cam surface on said pivotable clamping jaw; and iii. a projecting member on said pulling means adjacent the cam so located that when the elongated main body and pivoted elongated member are urged together, the free end of said driving arm first moves along the cam surface to simultaneously close the articulated clamping jaws and the stripping jaws and then engages the projecting member on said pulling means to pull said cutting jaws in a longitudinal direction to strip the sheathing from the end of a cable held by the clamping jaws.
Claim 2
Dependent Claim
293 words
A tool for stripping the sheathing from sheathed cables comprising: a. a pair of articulated clamping jaws for holding an end of a sheathed cable during stripping operations, a first of said clamping jaws forming one end of an elongated main body to which the second of said clamping jaws is pivotably connected, said pivotable clamping jaw having a portion extending backwardly from the pivot point and provided at its rear extremity with a cam surface; b. a pair of longitudinally movable, articulated stripping jaws adjacent the inner sides of the clamping jaws, said stripping jaws having cutting edges for cutting into the sheathing and for stripping said sheathing from the cable; c. pulling means on said elongated main body connected to the stripping jaws for pulling said stripping jaws in a direction longitudinal to a cable held in the clamping jaws; and d. means for operating said clamping jaws and stripping jaws comprising: i. an elongated member pivotably connected by one end thereof to the elongated main body and extending longitudinally backward away from the clamping jaws; ii. a biased driving arm pivoted at one end thereof to said elongated member, the free end of said driving arm engaging the cam surface on said pivotable clamping jaw; and iii. a projecting member on said pulling means adjacent the cam so located that when the elongated main body and pivoted elongated member are urged together, the free end of said driving arm first moves along the cam surface to simultaneously close the articulated clamping jaws and the stripping jaws and then engages the projecting member on said pulling means to pull said cutting jaws in a longitudinal direction to strip the sheathing from the end of a cable held by the clamping jaws.
