Abstract
Abstract A method of recovering non-ferrous metal conductors from a sheathed cable laid in the earth comprising excavating the earth at spaced intervals, such as 20 to 50 meters, along the cable, severing the cable, stripping off the sheath to expose the conductors adjacent the severed end or ends, and withdrawing the severed conductor length by supplying a pulling force to a severed end.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
103 words
A method of recovering non-ferrous metal conductors from a sheathed cable laid in the ground comprising: a. excavating the earth so as to expose a short length of the cable, b. cutting through the cable at the excavation and at a location spaced from the excavation, to thereby provide a severed length of the cable, c. stripping the sheath from the end of the severed length of the cable in the excavation to expose the conductors at the end of the severed length, and d. withdrawing the cable conductor by pulling on the thus stripped end of the conductor of the severed cable.
Claim 2
Independent Claim
103 words
A method of recovering non-ferrous metal conductors from a sheathed cable laid in the ground comprising: a. excavating the earth so as to expose a short length of the cable, b. cutting through the cable at the excavation and at a location spaced from the excavation, to thereby provide a severed length of the cable, c. stripping the sheath from the end of the severed length of the cable in the excavation to expose the conductors at the end of the severed length, and d. withdrawing the cable conductor by pulling on the thus stripped end of the conductor of the severed cable.
Claim 3
Dependent Claim
30 words
The method of claim 1, wherein after step (c) the exposed conductors are passed through a cable grip, and the cable conductor is withdrawn by pulling on the cable grip.
Claim 4
Dependent Claim
25 words
The method of claim 2, wherein following the passing of the exposed conductor through the cable grip, the ends of the conductor are bent over.
Claim 5
Dependent Claim
23 words
The method of claim 3, and further comprising attaching a rope to said cable grip, and pulling on said rope by a winch.
Claim 6
Dependent Claim
20 words
The method of claim 4, and further comprising passing said rope over anti-friction means at the edge of the excavation.
Claim 7
Dependent Claim
26 words
The method of claim 1, wherein the earth is excavated at a distance from said excavation, and the cable is cut through at both said excavations.
