Abstract
Abstract A tire repair patch having overlapping plies of reinforcing cords, a base cushion gum layer and an intermediate cushion gum layer positioned between at least two of the plies. The intermediate cushion gum layer has a thickness greater than the thickness of the plies and suspends some of the plies for distributing the forces transmitted through the patch at the injured portion of the tire.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
209 words
A tire repair patch for application to the inner surface of a tire at an injured portion comprising a plurality of overlapping plies of reinforcing cords and at least some of said plies having overlapping end portions, a base cushion gum layer underlying said plies at said underside for engagement with said inner surface of the tire, a top cushion gum layer overlying said plies at the opposite side of the patch from said underside, an intermediate cushion gum layer interposed between at least two of said plies of reinforcing cords, each of said overlapping plies being coated with rubber and having a thickness less than the thickness of said intermediate cushion gum layer, said intermediate cushion gum layer extending continuously between said overlapping end portions of at least two of said reinforcing plies, said base cushion gum layer being adapted for adherence to the inner surface of the tire to provide reinforcement of the tire in the area of said patch, and said reinforcing plies interposed between said base cushion gum layer and said intermediate cushion gum layer interacting with the remainder of said plies and said base and top cushion gum layers for distributing the forces transmitted through said patch at the injured portion of the tire.
Claim 2
Dependent Claim
209 words
A tire repair patch for application to the inner surface of a tire at an injured portion comprising a plurality of overlapping plies of reinforcing cords and at least some of said plies having overlapping end portions, a base cushion gum layer underlying said plies at said underside for engagement with said inner surface of the tire, a top cushion gum layer overlying said plies at the opposite side of the patch from said underside, an intermediate cushion gum layer interposed between at least two of said plies of reinforcing cords, each of said overlapping plies being coated with rubber and having a thickness less than the thickness of said intermediate cushion gum layer, said intermediate cushion gum layer extending continuously between said overlapping end portions of at least two of said reinforcing plies, said base cushion gum layer being adapted for adherence to the inner surface of the tire to provide reinforcement of the tire in the area of said patch, and said reinforcing plies interposed between said base cushion gum layer and said intermediate cushion gum layer interacting with the remainder of said plies and said base and top cushion gum layers for distributing the forces transmitted through said patch at the injured portion of the tire.
Claim 3
Dependent Claim
55 words
The tire repair patch of claim 1 wherein said plies of reinforcing plies further comprise working plies and body plies, said working plies being positioned between said base cushion gum layer and said intermediate cushion gum layer and said body plies being positioned between said intermediate cushion gum layer and said top cushion gum layer.
Claim 4
Dependent Claim
45 words
The tire repair patch of claim 2 wherein said working plies include two elongated overlapping plies with each of said plies having cords extending longitudinally of the ply and being positioned at substantially right angles to the cords of the other of said working plies.
Claim 5
Dependent Claim
54 words
The tire repair patch of claim 3 wherein said body plies include at least one pair of elongated overlapping plies of reinforcing cords and each of said plies having cords extending longitudinally of the ply and being positioned at substantially right angles to the cords of the other of said pair of body plies.
Claim 6
Dependent Claim
20 words
The tire repair patch of claim 4 wherein said body plies include at least two pair of said elongated plies.
Claim 7
Dependent Claim
44 words
The tire repair patch of claim 1 wherein said top cushion gum layer, said intermediate cushion gum layer and said base cushion gum layer extend beyond said plies of reinforcing cords and have edges bonded together to form a cushioning edge for said patch.
Claim 8
Dependent Claim
85 words
The tire repair patch of claim 1 wherein a second intermediate cushion gum layer is interposed between two of said plies at a position spaced from said first-mentioned intermediate cushion gum layer by at least one of said plies, each of said overlapping plies of reinforcing cords having a thickness less than the thickness of said second intermediate cushion gum layer so that said second intermediate cushion gum layer will further interact with said cushion gum layers for distributing the forces transmitted through said patch.
Claim 9
Dependent Claim
50 words
The tire repair patch of claim 7 wherein said second intermediate cushion gum layer is spaced from said top cushion gum layer by at least one of said plies and said first-mentioned cushion gum layer is spaced from said base cushion gum layer by at least two of said plies.
Claim 10
Dependent Claim
31 words
The tire repair patch of claim 8 wherein said first-mentioned intermediate cushion gum layer and said second intermediate cushion gum layer are spaced apart by at least four of said plies.
Claim 11
Dependent Claim
34 words
The tire repair patch of claim 7 wherein said first-mentioned and second intermediate cushion gum layers extend beyond the edges of said plies and are bonded together at an edge portion of said patch.
Claim 12
Dependent Claim
36 words
The tire repair patch of claim 10 wherein said base and top cushion gum layers extend beyond the edges of said first-mentioned and second intermediate cushion gum layers and are bonded together at said edge portion.
Claim 13
Dependent Claim
189 words
A tire repair patch for application to the inner surface of a tire at an injured portion comprising a plurality of overlapping plies of reinforcing cords and at least some of said plies having overlapping end portions, a base cushion gum layer underlying said plies at said underside for engagement with said inner surface of the tire, an intermediate cushion gum layer interposed between at least two of said plies of reinforcing cords, each of said overlapping plies being coated with rubber and having a thickness less than the thickness of said intermediate cushion gum layer, said intermediate cushion gum layer extending continuously between said overlapping end portions of at least two of said reinforcing plies, said base cushion gum layer being adapted for adherence to the inner surface of the tire to provide reinforcement of the tire in the area of said patch, and said reinforcing plies interposed between said base cushion gum layer and said intermediate cushion gum layer interacting with the remainder of said plies and said base cushion gum layer for distributing the forces transmitted through said patch at the injured portion of the tire.
Claim 14
Dependent Claim
189 words
A tire repair patch for application to the inner surface of a tire at an injured portion comprising a plurality of overlapping plies of reinforcing cords and at least some of said plies having overlapping end portions, a base cushion gum layer underlying said plies at said underside for engagement with said inner surface of the tire, an intermediate cushion gum layer interposed between at least two of said plies of reinforcing cords, each of said overlapping plies being coated with rubber and having a thickness less than the thickness of said intermediate cushion gum layer, said intermediate cushion gum layer extending continuously between said overlapping end portions of at least two of said reinforcing plies, said base cushion gum layer being adapted for adherence to the inner surface of the tire to provide reinforcement of the tire in the area of said patch, and said reinforcing plies interposed between said base cushion gum layer and said intermediate cushion gum layer interacting with the remainder of said plies and said base cushion gum layer for distributing the forces transmitted through said patch at the injured portion of the tire.
