Abstract
Abstract A tool for removing the sheath from cables. A cutting edge is positioned between two serrated drive rollers which engage with the cable periphery. Opposed to the drive rollers are support rollers. The drive rollers are rotated to move the tool on the cable. The drive rollers and cutting edge can be arranged to cut axially of the cable or circumferentially.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
129 words
Apparatus for cutting the sheath of a cable, comprising: a frame; a driving wheel mounted on the frame for engagement with the cable sheath; support means on the frame; a pressure roller mounted on the support means, and having limited movement in a direction normal to the rotational axis of the driving wheel; resilient means for urging the pressure roller in said direction in opposition to said driving wheel; additional means for moving the pressure roller towards the driving wheel, whereby the cable will be gripped therebetween; a cutter associated with one of said driving wheel and said pressure roller and adapted for setting for a predetermined depth of cut; and means for rotating the driving wheel to move the cable relative to the cutter to cut the sheath.
Claim 2
Dependent Claim
129 words
Apparatus for cutting the sheath of a cable, comprising: a frame; a driving wheel mounted on the frame for engagement with the cable sheath; support means on the frame; a pressure roller mounted on the support means, and having limited movement in a direction normal to the rotational axis of the driving wheel; resilient means for urging the pressure roller in said direction in opposition to said driving wheel; additional means for moving the pressure roller towards the driving wheel, whereby the cable will be gripped therebetween; a cutter associated with one of said driving wheel and said pressure roller and adapted for setting for a predetermined depth of cut; and means for rotating the driving wheel to move the cable relative to the cutter to cut the sheath.
Claim 3
Dependent Claim
76 words
Apparatus as claimed in claim 1, the cutter associated with the driving wheel, the driving wheel and cutter supported in a housing on the frame for rotation about an axis normal to the axis of rotation of the driving wheel between a first and a second position, the cutter alignEd in the first position for relative movement of the cable longitudinally and in the second position for relative movement of the cable about the cable axis.
Claim 4
Dependent Claim
21 words
Apparatus as claimed in claims 1 and 2, comprising two parallel spaced apart driving wheels, the cutter positioned between the wheels.
Claim 5
Dependent Claim
41 words
Apparatus as claimed in claims 1 and 2, comprising two pairs of pressure rollers, the rotational axes of the rollers of one pair inclined relative to the rotational axes of the rollers of the other pair to form a VEE formation.
Claim 6
Dependent Claim
27 words
Apparatus as claimed in claim 1 the support means for the pressure roller slidably mounted on said frame for movement towards and away from said driving wheel.
Claim 7
Dependent Claim
91 words
Apparatus as claimed in claim 1, including support means on said frame for supporting the roller, the support means including a bracket slidable on said frame towards and away from the driving wheel; a holder for said pressure roller mounted in said bracket for movement toward and away from the driving wheel; actuating means for moving the holder towards the driving wheel; and resilient means positioned between said actuating means and the holder urging the holder toward the driving wheel, whereby the roller is resiliently urged into contact with the cable.
Claim 8
Dependent Claim
12 words
Apparatus as claimed in claim 6, said actuating means comprising a cam.
Claim 9
Dependent Claim
35 words
Apparatus as claimed in claim 6, said bracket including a lever, and means urging said lever into engagement with formations on said frame, whereby the bracket can be positioned at desired locations on the frame.
Claim 10
Dependent Claim
17 words
Apparatus as claimed in claim 1 the means for rotating the driving wheel comprising a ratchet handle.
Claim 11
Dependent Claim
105 words
Apparatus as claimed in claim 2, including a sleeve attached to said frame, said housing mounted in said sleeve for rotation about said axis normal to the axis of rotation of the driving wheel, and for limited axial movement in said sleeve, resilient means urging the housing axially in said sleeve in a direction away from said pressure roller; means for moving said housing axially against said resilient means and for rotating said housing in said sleeve, and locating means for locating said housing at said first and second positions, said locating means disengaged by said moving of said housing axially against said resilient means.
Claim 12
Dependent Claim
54 words
Apparatus as claimed in claim 2 said cutter mounted for movement relative to said driving wheel along the axis of rotation of said housing, and means for moving the cutter along said axis to controllably adjust the position of the cutter relative to said driving wheel, whereby the depth of cut can be varied.
