Abstract
Abstract Frustoconical wedges for gripping cables are described and shown which are circumferentially divided into a plurality of complementary parts which are held in the assembled state by a retaining ring located in a circumferential recess. The wedge has a bore to receive the cable, the walls of which are helically grooved to correspond to the helical plies of the cable.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
149 words
In an assembly for gripping a multi-ply cable, a wedge having two longitudinal ends, a frustoconical outer surface between the ends and a helically grooved inner surface providing a bore to receive the cable extending longitudinally from end to end of the wedge, said helically grooved inner surface conforming substantially to the configuration of plies of a cable received in said bore, the wedge being circumferentially divided into a plurality of mutually separate complementary parts each of which extends from end to end of the wedge, and the circumferential divisions of the wedge extending helically along the latter in the interior of grooves at said inner surface of said bore helically along said grooves in the deepest parts thereof, the wedge further having a circumferential recess in its outer surface adjacent its larger end adapted to receive a retaining ring for maintaining the said parts in the assembled state.
Claim 2
Dependent Claim
149 words
In an assembly for gripping a multi-ply cable, a wedge having two longitudinal ends, a frustoconical outer surface between the ends and a helically grooved inner surface providing a bore to receive the cable extending longitudinally from end to end of the wedge, said helically grooved inner surface conforming substantially to the configuration of plies of a cable received in said bore, the wedge being circumferentially divided into a plurality of mutually separate complementary parts each of which extends from end to end of the wedge, and the circumferential divisions of the wedge extending helically along the latter in the interior of grooves at said inner surface of said bore helically along said grooves in the deepest parts thereof, the wedge further having a circumferential recess in its outer surface adjacent its larger end adapted to receive a retaining ring for maintaining the said parts in the assembled state.
Claim 3
Dependent Claim
149 words
In an assembly for gripping a multi-ply cable, a wedge having two longitudinal ends, a frustoconical outer surface between the ends and a helically grooved inner surface providing a bore to receive the cable extending longitudinally from end to end of the wedge, said helically grooved inner surface conforming substantially to the configuration of plies of a cable received in said bore, the wedge being circumferentially divided into a plurality of mutually separate complementary parts each of which extends from end to end of the wedge, and the circumferential divisions of the wedge extending helically along the latter in the interior of grooves at said inner surface of said bore helically along said grooves in the deepest parts thereof, the wedge further having a circumferential recess in its outer surface adjacent its larger end adapted to receive a retaining ring for maintaining the said parts in the assembled state.
Claim 4
Dependent Claim
149 words
In an assembly for gripping a multi-ply cable, a wedge having two longitudinal ends, a frustoconical outer surface between the ends and a helically grooved inner surface providing a bore to receive the cable extending longitudinally from end to end of the wedge, said helically grooved inner surface conforming substantially to the configuration of plies of a cable received in said bore, the wedge being circumferentially divided into a plurality of mutually separate complementary parts each of which extends from end to end of the wedge, and the circumferential divisions of the wedge extending helically along the latter in the interior of grooves at said inner surface of said bore helically along said grooves in the deepest parts thereof, the wedge further having a circumferential recess in its outer surface adjacent its larger end adapted to receive a retaining ring for maintaining the said parts in the assembled state.
Claim 5
Dependent Claim
64 words
In an assembly according to claim 1 further comprising a retaining ring in the said circumferentail recess, anchoring means having a frustoconical aperture in which said wedge is located for gripping a cable extending through said bore, and said retaining ring engaging a surface of said anchoring means for limiting the extent to which said complementary parts approach each other at said circumferential divisions.
Claim 6
Dependent Claim
44 words
In an assembly as recited in claim 2, said anchoring means having a flat surface in a plane normal to the axis of said bore engaging said retaining ring, and said retaining ring having a flat surface engaging said surface of said anchoring means.
