A tool for stripping jackets from cable insulation comprising means for holding a portion of the cable and means for clamping the cable against the holding means and cutting the jacket. The clamping and cutting means includes a surface for bearing against the exterior of the jacket on the cable and a cutter member for cutting the jacket, the cutter member being adjustable toward and away from the cable to vary the depth of cut of the jacket of cable held in the holding means. A cable jacket clamping and cutting device may be mounted on a tool having a pair of perpendicular, intersecting channels for holding cable and a releasable, spring-loaded lever arm for urging the device against cable held in either of the channels at a point above the intersection of the channels whereby the tool is rotatable and slidable relative to the axis of the cable to cut the cable jacket around its circumference and parallel to the axis. The device comprises a housing having means for mounting on the lever arm; a surface on the housing lower side for bearing against the exterior of the jacket to clamp cable in either of the channels; and a cutter member for cutting the jacket. A vertical shaft having threads on at least a portion of its exterior secures the cutter member. An annular knob rotatable in the housing having interior threads mating with the shaft threads moves the shaft and the cutter member toward and away from the cable to vary the depth of cut of the jacket of cable held in either of the channels.

Mechanism for adjusting depth of cut on wire and cable jackets

A tool for removing insulation from mid-span of a conductor cable which includes a frame with first and second jaw members, one of which is slidably mounted on the frame to close and cooperate with the other jaw member to secure cable in the tool for rotation of the frame relative to the cable. A circular ringing knife blade assembly is slidably mounted on the frame for movement toward and away from cable secured in the jaw members and upon extension of the circular knife blade and at least one full rotation of the frame in a first direction relative to the cable, the circular knife blade scores the jacket along a closed cut around the complete periphery of the cable. An insulation stripping assembly includes at least one blade edge for removing the radial thickness of the insulation from the cable. The blade edge is at a constant, fixed cutting angle and is mounted for movement along a straight line toward and away from the cable. An adjustable depth-limiting menas sets the maximum extension of the blade edge. Upon rotation of the tool frame in a second direction opposite the first direction relative to the cable, the blade edge cuts and lifts the insulation from the cable conductor. A second blade edge is mounted adjacent the first blade edge to cut the jacket in a helical direction and helically strip the insulation as the frame is rotated about the cable.

Cable stripper

Cable coring tool

A cable shaving tool for removing the outer covering of a cable at a point intermediate its ends, comprising a sectional shaving head adapted to be closed around the cable, a drive shaft operatively connected to the blade support in the shaving head, and remote means for driving the drive shaft and for adjusting and controlling the position of the shaving head elements to permit applying the shaving head to the cable and removing it therefrom; also the method of removing the outer covering of a cable.

Cable shaving tool

A tool for stripping covering from electrical cable which comprises a powered rotating tool which tangentially and radially cuts into the covering material and smoothly shaves a continuous cut of predetermined depth therefrom. A rotating blade shaves the covering continuously, which covering is fed between chopper blades into a discharge chute. The cable may be continuously fed through the bore of a rotating cutting tool and spindle and any length of covering removed.
