Abstract
Abstract A gasket assembly includes a gasket which defines an aperture, and a gasket attachment, such as a gasket extension or a metering insert, secured to the gasket. The gasket attachment includes a base having a flange which is in contact with one side of the gasket adjacent the gasket aperture and a lock plate generally axially spaced from the base and in rotatable engagement therewith. The lock plate is adapted for rotation relative to the base from a first position wherein the lock plate is generally radially within the gasket aperture to a second position wherein the gasket is clamped between the lock plate and the base flange.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
75 words
A gasket assembly having a gasket defining an aperture, said gasket aperture having an axis extending therethrough, and a gasket attachment comprising a base having a portion for engagement with said gasket adjacent said gasket aperture, and a lock plate having a portion movable relative to said base from a first position generally radially within said gasket aperture to a second position for engagement with another side of said first gasket adjacent said gasket aperture.
Claim 2
Dependent Claim
75 words
A gasket assembly having a gasket defining an aperture, said gasket aperture having an axis extending therethrough, and a gasket attachment comprising a base having a portion for engagement with said gasket adjacent said gasket aperture, and a lock plate having a portion movable relative to said base from a first position generally radially within said gasket aperture to a second position for engagement with another side of said first gasket adjacent said gasket aperture.
Claim 3
Dependent Claim
21 words
A gasket assembly as defined in claim 1 wherein said base comprises a boss extending generally axially into said gasket aperture.
Claim 4
Dependent Claim
37 words
A gasket assembly as defined in claim 2 wherein said boss comprises a generally flat and radially extending surface, and wherein said lock plate comprises a generally flat and radially extending surface axially abutting said boss surface.
Claim 5
Dependent Claim
24 words
A gasket assembly as defined in claim 1 wherein said base comprises an annular flange defining an aperture generally smaller than said gasket aperture.
Claim 6
Dependent Claim
31 words
A gasket assembly as defined in claim 4 wherein said lock plate defines an aperture and wherein said lock plate is rotatably affixed to said base by said annular base flange.
Claim 7
Dependent Claim
25 words
A gasket assembly as defined in claim 5 wherein said base further comprises means for limiting rotation of said lock plate relative to said base.
Claim 8
Dependent Claim
32 words
A gasket assembly as defined in claim 6 wherein said gasket attachment comprises means for indicating a direction of rotation of said lock plate from said first position to said second position.
Claim 9
Dependent Claim
32 words
A gasket as defined in claim 1 wherein said lock plate is rotatably engaged with said base and wherein said lock plate is rotatable from said first position to said second position.
Claim 10
Dependent Claim
42 words
A gasket assembly as defined in claim 8 wherein said lock plate portion comprises a generally radially extending lock flange, wherein said gasket is clampingly received between said lock flange and said base when said lock plate is in said second position.
Claim 11
Dependent Claim
42 words
A gasket assembly as defined in claim 8 wherein said generally radially extending lock plate flange comprises a generally axially flared portion, wherein the axial distance between said base and said axially flared portion is greater than the thickness of said gasket.
Claim 12
Dependent Claim
41 words
A gasket assembly as defined in claim 10 wherein said lock plate comprises another generally radially extending flange clampingly engageable with said first gasket member, said another flange circumferentially spaced about 180° around said lock plate from said lock plate flange.
Claim 13
Dependent Claim
26 words
A gasket assembly as defined in claim 5 wherein said base portion comprises a generally radially extending flange abutting said gasket continuously around said gasket aperture.
