Cable spearing and cutting apparatus

Claim 3

The apparatus of claim 1, wherein said plurality of drive rod means comprises two drive rods for supporting said cutting means at two spaced positions.

Claim 4

The apparatus of claim 2, wherein said cutting means comprises a blade and blade holder, and wherein said housing further includes a cap through which said drive rods slidably move, and means for slidably sealing said drive rods in said cap.

Claim 7

The device of claim 4, wherein said housing includes a chamber, and wherein said guide means is disposed diametrically about said chamber.

Claim 8

The device of claim 5, wherein said guide means comprises a pair of slots positioned with respect to said chamber so as to substantially divide the same and act to confine the movement of said blade means.

Claim 9

A cable cutter and clamp adapted for attachment to the periphery of a cable comprising a fixture formed with guide slots, a cutting edge and holder therefor adapted for movement relative to said fixture, chain means detachably coupled to said fixture and operable to lock the cable to said fixture, cable support means interposed between said chain means and the cable periphery and placed substantially opposed to said cutting edge and holder, and prime mover means to effect the relative movement of said cutting edge so that as the cable is sheared and cable support means acts to distribute the stress on the cable to obviate distortion of the cable opposite said cutting edge.

Claim 10

A cable cutter and clamp adapted for attachment to the periphery of a cable comprising a fixture formed with guide slots, a cutting edge and holder therefor adapted for movement relative to said fixture, chain means detachably coupled to said fixture and operable to lock the cable to said fixture, cable support means interposed between said chain means and the cable periphery and placed substantially opposed to said cutting edge and holder, and prime mover means to effect the relative movement of said cutting edge so that as the cable is sheared and cable support means acts to distribute the stress on the cable to obviate distortion of the cable opposite said cutting edge.

Claim 11

The cable cutter and clamp of claim 7, wherein said chain means comprises a plurality of link chains, and wherein said cable support means is adapted to concomitantly engage said plurality of link chains thereby to prevent the cable from deforming at said plurality of link chains while the cable is being cut.

Claim 12

The cable cutter and clamp of claim 7, wherein said cable support is defined by a first arcuate surface adapted to fit about a peripheral portion of the cable and a second surface opposed to said first surface for concomitant engagement with said plurality of link chains.

Claim 13

A cable cutter including in combination a housing formed with diametrically opposed guide means, a blade operable for relative movement with respect to said housing and confined to move in said guide means during at least a portion of the travel thereof, clamping means disposed in said housing and adapted to lock the cable thereto, cable support means interposed between a portion of the cable periphery and said clamping means, a plurality of drive rods having the respective one ends thereof attached to said blade and relatively spaced from each other, and prime mover means attached to the respective other ends of said plurality of drive rods so that as said prime mover means causes the relative movement of said blade, said cable support means spaces said clamping means from the cable periphery and prevents deformation of the cable to enable the cable to be accurately sheared.

Claim 14

A cable cutter including in combination a housing formed with diametrically opposed guide means, a blade operable for relative movement with respect to said housing and confined to move in said guide means during at least a portion of the travel thereof, clamping means disposed in said housing and adapted to lock the cable thereto, cable support means interposed between a portion of the cable periphery and said clamping means, a plurality of drive rods having the respective one ends thereof attached to said blade and relatively spaced from each other, and prime mover means attached to the respective other ends of said plurality of drive rods so that as said prime mover means causes the relative movement of said blade, said cable support means spaces said clamping means from the cable periphery and prevents deformation of the cable to enable the cable to be accurately sheared.

Claim 15

The cable cutter of claim 10 wherein said clamping means includes at least one chain having two ends and formed with a plurality of interconnected links, pins means attached to one portion of said housing for demountably locking one end of said chain thereto, and aperture means placed on another portion of said housing for receiving the other end of said chain.

Claim 16

The cable cutter of claim 11 wherein each of said links has an area of reduced cross section, and wherein said pin means comprises at least two pins, a passageway in said housing that is adapted to receive said pin pair with one of the pins of said pin pair being operable to release said chain from said passageway.

Claim 17

The cable cutter of claim 12, wherein said clamping means further comprises an additional chain, and an additional one of said passageway and cooperating pin pair so that each one of said chains is adapted for detachable securement in a respective passageway whereby the cable is nestled against said housing as said chains extend thereabout.
