Abstract

Abstract A gasket assembly having improved compression stoppers. The stoppers facilitate the rapid, easy and certain securance of the stoppers in a predetermined relationship in a gasket assembly. A gasket assembly, in accordance with this invention desirably comprises a main body having a pair of side sections, each comprising a self supporting core member and compressible facings fast with the core member and defining fastener openings through which fasteners are adapted to pass. The core members extend along the side sections of the gasket assembly, said facings and said core providing side sections of a first thickness. The main body further comprises end portions joining the side sections. Separate compression stoppers are provided in the fastener openings. The compression stoppers are compression and high-temperature resistant, and are secured in the openings in the main gasket body, the compression stoppers comprising a pair of press-fit annuli together defining a peripheral groove means in which the core member is disposed, thereby to retain the compression stoppers in the fastener openings and in a predetermined relationship to the outer surfaces of the facings.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 185 words
A gasket assembly comprising a main body having a pair of side sections, each comprising a self-supporting core member and compressible facings fast with said core member and defining fastener openings through which fasteners are adapted to pass, said core members extending along said side sections of the gasket assembly, said facings and said core providing side sections of a first thickness, and end portions joining said side sections, and separate compression stoppers in said fastener openings, said compression stoppers being compression and high-temperature resistant, and being secured in said openings in said main gasket body, said compression stoppers comprising a pair of press-fit annuli together defining a peripheral groove means in which said core member is disposed, thereby to retain said compression stoppers in said fastener openings and in a predetermined relationship to the outer surfaces of said facings, and said compression stoppers being of a second thickness less than said first thickness, whereby when said gasket assembly is disposed to be compressed between elements to be sealed, said compression stoppers limit compression of said gasket assembly to prevent destruction of said gasket assembly.
Claim 2
Dependent Claim 185 words
A gasket assembly comprising a main body having a pair of side sections, each comprising a self-supporting core member and compressible facings fast with said core member and defining fastener openings through which fasteners are adapted to pass, said core members extending along said side sections of the gasket assembly, said facings and said core providing side sections of a first thickness, and end portions joining said side sections, and separate compression stoppers in said fastener openings, said compression stoppers being compression and high-temperature resistant, and being secured in said openings in said main gasket body, said compression stoppers comprising a pair of press-fit annuli together defining a peripheral groove means in which said core member is disposed, thereby to retain said compression stoppers in said fastener openings and in a predetermined relationship to the outer surfaces of said facings, and said compression stoppers being of a second thickness less than said first thickness, whereby when said gasket assembly is disposed to be compressed between elements to be sealed, said compression stoppers limit compression of said gasket assembly to prevent destruction of said gasket assembly.
Claim 3
Dependent Claim 84 words
A gasket assembly in accordance with claim 1, and wherein said pair of annuli comprises a first member having a flat stopper surface, and defining a central opening to receive a bolt, a truncated conical surface, and a sleeve opposite said flat stopper surface, and a second washer-like.member having a second flat stopper surface, a central opening adapted to receive said sleeve and a truncated conical surface, said conical surfaces converging inwardly toward a central portion of said stopper to provide said groove means.
Claim 4
Dependent Claim 22 words
A gasket assembly in accordance with claim 1, and wherein said second thickness is at least seventy-five percent of said first thickness.
Claim 5
Dependent Claim 18 words
A gasket in accordance with claim 1, and wherein said self supporting core members are formed of metal.
