Abstract

Abstract A lightweight, easily-installed boot for wire rope terminations is water-tight and adaptable to a variety of wire rope terminations. The boot is placed on the surface of a wire rope and secured to the socket nose of the termination to seal the termination-wire rope interface; then, a polyolefin heat shrinkable tube is placed over the head of the boot to seal the wire rope-boot interface.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 206 words
In the method of attaching a termination to the end section of a wire rope, wherein said section is inserted into the socket portion of said termination and secured within said socket, the improvement which comprises: a prior to insertion into the termination 1. passing a tube of heat shrinkable plastic over said end section a distance sufficiently removed from the terminus thereof; 2. inserting the end section into the head of a boot, said boot comprising (i) a tube-like portion having an inner diameter tightly fitting the circumferential surface of said end section and an effective outer diameter smaller than the inner diameter of said heat shrinkable tube, and (ii) a flange portion integral with and surrounding the trailing end of said tube-like portion, and (b) after securing the end section in the socket 3. connecting said boot flange portion and said socket so that the interface thereof is sealed 4. sliding said heat shrinkable tubing over the tube-like portion of said boot so that the interface of the lead end of the boot and wire rope is covered by said heat shrinkable tubing and 5. heating shrinking said heat shrinkable tubing so that the interface of said boot and said wire rope is sealed.
Claim 2
Dependent Claim 206 words
In the method of attaching a termination to the end section of a wire rope, wherein said section is inserted into the socket portion of said termination and secured within said socket, the improvement which comprises: a prior to insertion into the termination 1. passing a tube of heat shrinkable plastic over said end section a distance sufficiently removed from the terminus thereof; 2. inserting the end section into the head of a boot, said boot comprising (i) a tube-like portion having an inner diameter tightly fitting the circumferential surface of said end section and an effective outer diameter smaller than the inner diameter of said heat shrinkable tube, and (ii) a flange portion integral with and surrounding the trailing end of said tube-like portion, and (b) after securing the end section in the socket 3. connecting said boot flange portion and said socket so that the interface thereof is sealed 4. sliding said heat shrinkable tubing over the tube-like portion of said boot so that the interface of the lead end of the boot and wire rope is covered by said heat shrinkable tubing and 5. heating shrinking said heat shrinkable tubing so that the interface of said boot and said wire rope is sealed.
Claim 3
Dependent Claim 26 words
The improvement according to claim 1 wherein the end of said socket has external threads, said flange portion of said boot has internal threads mating thereto.
Claim 4
Dependent Claim 26 words
The improvement according to claim 1 wherein mastic is applied to the interface of said boot and said wire rope prior to heat shrinking said tubing.
Claim 5
Dependent Claim 30 words
The improvement according to claim 1 wherein mastic is applied to the inteface of said socket and said wire rope prior to connecting said boot flange portion and said socket.
Claim 6
Dependent Claim 32 words
The improvement according to claim 1 wherein an O-ring tightly fitting said wire rope is positioned at the interface of said boot and said wire rope prior to heat shrinking said tubing.
Claim 7
Dependent Claim 36 words
The improvement according to claim 1 wherein an O-ring tightly fitting said wire rope is positioned at the interface of said socket and said wire rope prior to connecting said boot flange portion and said socket.
