Abstract
Abstract An elongated body includes a strip of aluminized or fiberglass cloth to be wrapped around a pipe coupling, one or more liner strips, and means for separably fastening its ends together, the liner strips being loosely slidable relatively to the body during wrapping of the assembly of the body and liner strips around the pipe coupling; and specifically the liner strips are held against displacement from the body by flexible narrow straps that have their end secured to the body and extend transversely of the body and overlie the liner strips.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
100 words
A shield for a pipe joint comprising an elongated one-piece pliable fabric body of a length and width to be wrapped around a pipe coupling with its ends overlapped, means for separably connecting said ends together, a pliable fabric liner strip confined wholly within the boundries of said body and extending centrally longitudinally of said body and slidably contacting one side of the body, and means separably holding said liner strip on the body against unintended displacement therefrom and providing for relatively longitudinal sliding of said liner strip and said body during wrapping of the shield around a pipe coupling.
Claim 2
Dependent Claim
100 words
A shield for a pipe joint comprising an elongated one-piece pliable fabric body of a length and width to be wrapped around a pipe coupling with its ends overlapped, means for separably connecting said ends together, a pliable fabric liner strip confined wholly within the boundries of said body and extending centrally longitudinally of said body and slidably contacting one side of the body, and means separably holding said liner strip on the body against unintended displacement therefrom and providing for relatively longitudinal sliding of said liner strip and said body during wrapping of the shield around a pipe coupling.
Claim 3
Dependent Claim
65 words
A shield as defined in claim 1 wherein the means for attaching the liner to the body comprises holding straps extending transversely of said body with their ends secured to the body and with their intermediate portions loosely overlying said liner strip and holding said liner strip against displacement from the body and providing for free longitudinal sliding of the liner relatively to the body.
Claim 4
Dependent Claim
74 words
A shield as defined in claim 2 wherein the body has longitudinal edge portions folded inwardly over the main portion providing a channel between the inner margins of said folded edge portions in which said liner strip is slidably disposed, and the end portions of said holding straps are secured between said folded edge portions and the main portion of the body while the intermediate portions of said straps loosely overlie said liner strip.
Claim 5
Dependent Claim
38 words
A shield as defined in claim 2 wherein one end portion of said body is infolded over the main portion and one end of the liner strip is loosely received between said infolded portiOn and the main portion.
Claim 6
Dependent Claim
72 words
A shield as defined in claim 2 wherein one end portion of said body is infolded over the main portion and one end of the liner strip is loosely received between said infolded portion and the main portion and wherein the other end portion of the body is folded inwardly and the corresponding end of the liner strip is in spaced juxtaposed relation to the inner margin of said inwardly folded portion.
Claim 7
Dependent Claim
65 words
A shield for a pipe joint as defined in claim 3, with the addition of draw strings disposed in the folds between said inwardly folded edge portions and the main portion of the body, having its ends projecting through apertures in the body for drawing said edge portions and the main portion around the pipe joint and adapted to have their ends separably connected together.
