Abstract
Abstract A protective wrapping for an elongated member of generally circular cross section, and particularly an abrasion resistant wrapping to protect marine cables and conduits. The wrapping is a helically oriented element formed of laminations preventing it from being opened outwardly and away from the protected cable, but allowing the cable to flex. The wrapping can be installed by placement crosswise on the cable and winding it about the cable to seat successive turns. Clamps, or a helical filler located between turns of the element, are used to axially extend the wrapping to effect a tight grip upon the protected cable.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
40 words
A combination according to claim 1 wherein the contacting sides of said turns of said filler and said turns of said element are complementally sloped whereby said turns of said filler tend to wedge apart said turns of said element.
Claim 2
Dependent Claim
57 words
A combination according to claim 1 wherein the direction of slope of said sides of said filler and said element defines an axially wider inner portion for each of said turns of said filler, compared to the adjacent turns of said element, whereby said turns of said filler exert a bias upon said turns of said element.
Claim 3
Dependent Claim
176 words
In combination with an elongated member of generally circular cross section, a protective wrapping comprising: a helically extending element disposed about said elongated member in sufficiently close-fitting relation that axial extension of said element increases the axial length of the space between the helical turns and decreases the inner diameter of said element, whereby said element tightly grips said elongated member, said element including a plurality of generally parallel, axially oriented, and helically extending alternating laminations of elastomeric material and fabric material bonded together whereby said helical turns strongly resist deformation radially outwardly in a direction effective to increase the diameter of said turns; and an elastomeric helically extending filler having its helical turns disposed within the spaces between said helical turns of said element in generally coextensive relation, the unstretched axial thickness of said filler being slightly greater than the corresponding axial length of the space between adjacent turns of said element whereby said filler in said space is stretched and exerts a bias upon said element whereby said element tightly grips said elongated member.
Claim 4
Dependent Claim
30 words
A combination according to claim 4 wherein said elastomeric material of said element is a tough, veHicle tread wear grade of rubber and said fabric material is woven glass cloth.
