Abstract
Abstract A clamp for a convolute wire cable or the like including a socket member having a conically tapered recess extending therethrough and a unitary inner core portion of substantially conico-frustrum configuration seated in the recess with the convolute strands of the cable being secured within helical grooves formed on the outer periphery of the core portion. The core portion includes an elongated conically tapered smooth bore extending along its longitudinal center axis and has one side thereof enlarged with respect to the other. An inner wedge is disposed in the enlarged side of the bore and mates with the other side forming a cylindrical central bore for receiving the center strand of the cable therein. In this manner, the inner wedge may be hammered down into the enlarged side of the bore to firmly grip the center strand of the cable while the socket member is forced onto the core portion to firmly grip the convolute strands of the cable within the socket member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
188 words
A clamp for a cable or the like wherein said cable comprises a plurality of outer convolute strands surrounding a center strand, said clamp comprising: a. a socket member having a conically tapered recess extending therethrough; b. a unitary inner core portion of substantially conico-frustrum configuration, said inner core portion being adapted to seat in said recess while clamping onto the convolute outer strands of said cable, said core portion having a plurality of helically formed external grooves extending in the direction of the longitudinal center axis of said core portion formed in the outer periphery thereof for receiving said convolute strands therein, said core portion having an elongated conically tapered bore extending substantially along its longitudinal center axis and having one side thereof enlarged with respect to the other to accommodate an inner wedge therein; and c. an inner wedge having an outer surface conforming substantially to the enlarged conically tapered side of said bore and an inner surface adapted to mate with the other side of said bore to form a generally cylindrical central bore for receiving and gripping therebetween the center strand of said cable.
Claim 2
Dependent Claim
188 words
A clamp for a cable or the like wherein said cable comprises a plurality of outer convolute strands surrounding a center strand, said clamp comprising: a. a socket member having a conically tapered recess extending therethrough; b. a unitary inner core portion of substantially conico-frustrum configuration, said inner core portion being adapted to seat in said recess while clamping onto the convolute outer strands of said cable, said core portion having a plurality of helically formed external grooves extending in the direction of the longitudinal center axis of said core portion formed in the outer periphery thereof for receiving said convolute strands therein, said core portion having an elongated conically tapered bore extending substantially along its longitudinal center axis and having one side thereof enlarged with respect to the other to accommodate an inner wedge therein; and c. an inner wedge having an outer surface conforming substantially to the enlarged conically tapered side of said bore and an inner surface adapted to mate with the other side of said bore to form a generally cylindrical central bore for receiving and gripping therebetween the center strand of said cable.
Claim 3
Dependent Claim
28 words
The clamp of claim 1 wherein said helically formed grooves are separated by lands having a smooth outer surface and the walls of said tapered recess are smooth-facEd.
Claim 4
Dependent Claim
28 words
The clamp of claim 1 wherein all of the walls of said conically tapered bore are smooth-faced and the outer and inner surfaces of said wedge are smooth-faced.
Claim 5
Dependent Claim
91 words
The clamp of claim 1 wherein both the enlarged side of said conically tapered bore and the other side thereof are substantially semi-circular in cross-section with said enlarged side being substantially greater in diameter than the diameter of said other side at the point of greatest diameter of said core portion and gradually tapering downwardly to the point of smallest diameter of said core portion, the diameter of said enlarged side being substantially equal to the diameter of said other side at the point of smallest diameter of said core portion.
Claim 6
Dependent Claim
75 words
The clamp of claim 1 whereby said inner wedge is generally semi-circular in cross-section and has an inner diameter substantially equal to the diameter of said other side and an outer diameter at its point of greatest outer diameter substantially equal to the diameter of said enlarged side at the point of its greatest diameter and gradually tapering downwardly to a diameter substantially equal to the point of the smallest diameter of said enlarged side.
Claim 7
Dependent Claim
50 words
The clamp of claim 5 wherein said inner wedge fits securely in said enlarged side and mates with said other side in a manner forming said generally cylindrical central bore, said central bore being slightly less in cross-sectional diameter than the cross-sectional diameter of said center strand of said cable.
Claim 8
Dependent Claim
23 words
The clamp of claim 1 wherein a plurality of circumferential serrations are provided along the inner and outer surfaces of said inner wedge.
