Abstract
Abstract A multi-wire member in which the outer layer comprises alternate base and oversize wires wherein the oversize wires have been deformed into interlocking engagement with each other and with respect to the wires comprising the next underlying layer of the member to produce a smooth and substantially continuous outer surface.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
93 words
In a multi-wire member, the improvement wherein the outer layer of the member comprises: a. a plurality of helically wrapped base wire structures; b. a plurality of oversize wires disposed alternately between each two base wire structures, each oversize wire having a normal undeformed shape extending radially outwardly of said base wires and being deformed into interlocking engagement with the base wire structures on either side thereof, each oversize wire is deformed with the outer surface regions of the base wires defining a relatively smooth and substantially continuous outer surface of the member.
Claim 2
Dependent Claim
93 words
In a multi-wire member, the improvement wherein the outer layer of the member comprises: a. a plurality of helically wrapped base wire structures; b. a plurality of oversize wires disposed alternately between each two base wire structures, each oversize wire having a normal undeformed shape extending radially outwardly of said base wires and being deformed into interlocking engagement with the base wire structures on either side thereof, each oversize wire is deformed with the outer surface regions of the base wires defining a relatively smooth and substantially continuous outer surface of the member.
Claim 3
Dependent Claim
24 words
The improvement according to claim 1 wherein: a. the multi-wire member is a strand with each base wire structure defined by a single wire.
Claim 4
Dependent Claim
62 words
The improvement according to claim 2 wherein: a. the multi-wire strand has a plurality of layers; and b. each oversize wire is deformed by radial compressive forces applied thereto such that it at least partially surrounds in intimate surfacE-to-surface relationship each base wire on either side thereof and each wire of the next underlying layer of the strand facing said oversize wire.
Claim 5
Dependent Claim
45 words
The improvement according to claim 3 wherein: a. each oversize wire is deformed such that the outer surface regions of the oversize wires together with the outer surface regions of the base wires define a relatively smooth and substantially continuous outer surface of the strand.
Claim 6
Dependent Claim
28 words
The improvement according to claim 4 wherein: a. the base wires are made of relatively hard material; and b. the oversize wires are made of relatively soft material.
Claim 7
Dependent Claim
55 words
The improvement according to claim 5 wherein: a. each base wire and one of the wires comprising the next underlying layer of the strand are positioned with respect to each other such that the longitudinal axis of each intersects a common line extending outwardly in a radial direction from the center axis of the strand.
Claim 8
Dependent Claim
50 words
The improvement according to claim 5 wherein: a. each base wire is substantially round in cross-sectional shape both before and after said redially compressive forces are applied to the oversize wires; and b. each oversize wire is initially round in cross-sectional shape before said radially compressive forces are applied thereto.
Claim 9
Dependent Claim
20 words
The improvement according to claim 5 wherein a plurality of said strands are wrapped together to form a wire rope.
