Abstract
Abstract PIPE SEAL Abstract of the Disclosure A gasket which is particularly suited for sealing the annular space between a pipe and a port in an underground structure is disclosed. The gasket comprises a hollow annular ring which surrounds the pipe and is connected by a narrow neck to a base at least partially embedded in the underground structure. The base has means extending around its outer periphery to mount the seal securely in the manhole and to provide a block against water seepage across the periphery of the gasket.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
138 words
A resilient gasket for sealing an annular space between a pipe and a surrounding aperture in a pipe receiving structure, comprising: an annular ring adapted to engage the outer periphery of the pipe, a flexible neck integral with said ring and extending outwardly therefrom, a base surrounding said neck integral therewith, said base having a portion adapted to be embedded within said pipe receiving structure and having a portion adapted to be exposed to said pipe when said gasket is in operative association with said pipe and said pipe receiving structure, said exposed portion extending laterally of said neck in opposite directions beyond the ring, said flexible neck cooperating with said base to afford both lateral and radial motion of the ring relative to the base and compression of the ring against the exposed portion of the base.
Claim 2
Dependent Claim
138 words
A resilient gasket for sealing an annular space between a pipe and a surrounding aperture in a pipe receiving structure, comprising: an annular ring adapted to engage the outer periphery of the pipe, a flexible neck integral with said ring and extending outwardly therefrom, a base surrounding said neck integral therewith, said base having a portion adapted to be embedded within said pipe receiving structure and having a portion adapted to be exposed to said pipe when said gasket is in operative association with said pipe and said pipe receiving structure, said exposed portion extending laterally of said neck in opposite directions beyond the ring, said flexible neck cooperating with said base to afford both lateral and radial motion of the ring relative to the base and compression of the ring against the exposed portion of the base.
Claim 3
Dependent Claim
57 words
The gasket according to Claim 1 wherein said neck has both lateral and radial dimensions which are substantially less than the outside diameter of said ring, and said base has a lateral dimension which is substantially wider than said ring so that the gasket has an overall radial dimension which is less than its overall lateral dimension.
Claim 4
Dependent Claim
29 words
The gasket according to Claim 2 wherein the exposed portion of said base diverges outwardly and laterally at a dihedral angle relative to said neck on opposite sides thereof.
Claim 5
Dependent Claim
17 words
The gasket according to Claim 3 wherein said annular ring is hollow and has a circular cross-section.
Claim 6
Dependent Claim
24 words
The gasket according to Claim 4 having a cross-section which is symmetrical with respect to a radial line through the center of the ring.
Claim 7
Dependent Claim
45 words
The gasket according to Claim 5 wherein said portion of said base adapted to be embedded in said pipe receiving structure includes means defining a labyrinth about the outer periphery thereof to form a water block when in operative association with said pipe receiving structure.
Claim 8
Dependent Claim
42 words
The gasket according to Claim 6 wherein said portion of said base adapted to be embedded in said pipe receiving structure has an annular peripheral groove and said labyrinth defining means includes a T-shaped cross-section of said base received in said groove.
Claim 9
Dependent Claim
58 words
The gasket according to Claim 1 and wherein said base has a pair of laterally opening recesses intermediate said portions adapted to be exposed and embedded, and including a pair of mounting rings each having a lateral flange received within one of said recesses and each having outwardly extending mounting flanges for embedding in said pipe receiving structure.
Claim 10
Dependent Claim
46 words
The gasket according to Claim 8 wherein the lateral flange extends both radially and laterally outward and said mounting flange is radially and laterally inturned with respect to said lateral flange to receive therebetween a portion of said pipe receiving structure when in operative association therewith.
Claim 11
Dependent Claim
30 words
The gasket according to Claim 9 wherein said mounting rings are continuous and are shaped to form a mechanical bond in said pipe receiving structure when in operative association therewith.
Claim 12
Dependent Claim
129 words
A gasket assembly for sealing an annular space between a pipe and a surrounding aperture in a molded pipe receiving structure, comprising: a compressible annular ring adapted to engage the outer periphery of the pipe, a base connected to said annular ring in a manner affording lateral movement of the ring relative to the base, and means mounting said base into the molded pipe receiving structure, said mounting means including means providing a pair of lateral recesses in said base and a pair of mounting rings linking said base to said structure, each of said mounting rings having lateral flanges engaging in said recesses and each having mounting flanges extending outwardly therefrom and embedded in said molded structure, whereby the gasket is firmly mounted in the pipe receiving structure.
Claim 13
Dependent Claim
129 words
A gasket assembly for sealing an annular space between a pipe and a surrounding aperture in a molded pipe receiving structure, comprising: a compressible annular ring adapted to engage the outer periphery of the pipe, a base connected to said annular ring in a manner affording lateral movement of the ring relative to the base, and means mounting said base into the molded pipe receiving structure, said mounting means including means providing a pair of lateral recesses in said base and a pair of mounting rings linking said base to said structure, each of said mounting rings having lateral flanges engaging in said recesses and each having mounting flanges extending outwardly therefrom and embedded in said molded structure, whereby the gasket is firmly mounted in the pipe receiving structure.
Claim 14
Dependent Claim
54 words
The gasket assembly according to claim 11 wherein said annular ring is connected to said base by a narrow neck integral with said ring and said base, said neck adapted to be disposed at an angle relative to said base to enable a pressure pocket to one side of the gasket to be formed.
Claim 15
Dependent Claim
71 words
The gasket assembly according to claim 12 wherein said base extends laterally outward in opposite directions from said neck and has interior surfaces tapering laterally and radially at a dihedral angle from said neck, said lateral mounting ring flanges forming similarly tapering extensions of said interior surfaces and extending in spaced relation with said pipe to enable the pipe to be disposed at an angle with respect to its receiving structure.
Claim 16
Dependent Claim
33 words
The gasket assembly according to claim 13 wherein said annular ring has a hollow circular cross-section and is fabricated of a predetermined length of extruded rubber formed into a circle and bonded endwise.
