Abstract
Abstract Apparatus for salvaging underground and overhead electrical cable includes a mobile platform, such as a motor truck, on which a cable-receiving tubular guide assembly is adjustably mounted for guiding cable from a cable-pulling toothed sheave supported at the rearward end of the guide assembly to a travelling guillotine type of cable cutter supported at the forward end. The cable cutter is synchronized to travel with the cable and to cut the cable into short lengths. After each cut of the cable, the cutter is synchronized to travel with the cable and to cut the cable into short lengths. After each cut of the cable, the cutter is retracted to its start position. Additionally, a pusher may be provided to push into the cutter the end portions of cable which have passed forwardly beyond the cable-pulling sheave and which, except for the pusher, may be left in the tubular guide assembly.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
94 words
Apparatus for salvaging electrical cable from underground and overhead installations, said apparatus comprising in combination: a. a mobile platform; b. a cable-guiding tubular assembly mounted on said mobile platform and adapted to be inclined upwardly in the discharge direction; c. a cable-pulling sheave; d. means supporting said sheave on one end of said tubular assembly; e. said sheave having inclined teeth on opposite sides of the center line forming a V-notch therebetween; f. sheave-drive means mounted on said sheave support means; and g. cable-cutting means supported on the other end of said tubular assembly.
Claim 2
Dependent Claim
94 words
Apparatus for salvaging electrical cable from underground and overhead installations, said apparatus comprising in combination: a. a mobile platform; b. a cable-guiding tubular assembly mounted on said mobile platform and adapted to be inclined upwardly in the discharge direction; c. a cable-pulling sheave; d. means supporting said sheave on one end of said tubular assembly; e. said sheave having inclined teeth on opposite sides of the center line forming a V-notch therebetween; f. sheave-drive means mounted on said sheave support means; and g. cable-cutting means supported on the other end of said tubular assembly.
Claim 3
Dependent Claim
30 words
Apparatus according to claim 1 wherein said teeth of said cable-pulling sheave are of truncated conical shape and are located at spaced-apart intervals on the inner surfaces of said sheave.
Claim 4
Dependent Claim
24 words
Apparatus according to claim 2 wherein said teeth on one side of said sheave are staggered with respect to those on the other side.
Claim 5
Dependent Claim
39 words
Apparatus according to claim 1 including cam wedge means mounted on said sheave support means, and means for moving said cam wedge means for forcing the cable down into the V-notch formed by the said teeth of said sheave.
Claim 6
Dependent Claim
24 words
Apparatus according to claim 1 including auxiliary pulling and compresSion means attached to said sheave-drive means for pulling and flattening bundles of individual cables.
Claim 7
Dependent Claim
35 words
Apparatus according to claim 1 wherein said means for supporting said sheave on one end of said tubular cable-guiding assembly includes a collar rotatable on said tubular assembly for adjusting the position of said sheave.
Claim 8
Dependent Claim
18 words
Apparatus according to claim 1 wherein said sheave-drive means includes a fluid gear motor and planetary speed reducer.
Claim 9
Dependent Claim
29 words

Apparatus according to claim 1 wherein a plurality of hydraulic cylinder pistons are employed to mount said tubular cable-guiding assembly on said truck, and wherein said pistons are adapted to adjust the elevation and angle of inclination of said tubular assembly.
Claim 11
Dependent Claim
30 words
Apparatus according to claim 9 wherein hydraulic cylinder pistons are also employed to adjust the angle of said tubular cable-guiding assembly relative to the longitudinal axis of said mobile platform.
Claim 12
Dependent Claim
67 words
Apparatus according to claim 1 wherein said cable-cutting means comprises: a. a cutting blade; b. means for carrying said blade forwardly along a path which converges with that of the cable path and for forcing said blade into and through the forwardly-moving cable; c. means for returning said blade to its start position; and d. means for repeating cyclically said forward and return travels of said blade.
Claim 13
Dependent Claim
30 words
Apparatus according to claim 11 wherein said cutting-blade carrying means includes a carriage, a track for said carriage, and hydraulic cylinder piston means for moving said carriage forwardly and rearwardly.
Claim 14
Dependent Claim
14 words
