Abstract
Abstract A gasket of joined sections, each section having a tongue and recess with the tongue of one section receivable in the recess of another section, the tongues and recesses having engageable side walls of resilient material for preventing leakage through the joint, the recess side walls being parallel so as to be sealingly engaged by the tongue side walls regardless of the distance that the tongue is entered into the recess, and opposed faces of each section having raised resilient lips along the edges thereof with lip portions along the edges of the tongues and recesses being deformable into sealing engagement with each other.

Claim 3
Dependent Claim
20 words
The gasket of claim 1 in which each section has a first clamping face from which the respective lip projects.
Claim 4
Dependent Claim
13 words
The gasket of claim 1 in which said lips are of elastomeric material.
Claim 5
Dependent Claim
28 words
The gasket of claim 1 in which each section comprises a part of rigid material and said lips edges are of resilient material mounted on said rigid part.
Claim 6
Dependent Claim
44 words
The gasket of claim 2 in which each section has a second clamping face opposite the first clamping face from which other lips project along the respective edge, and said other lips being of elastomeric material and deformaBle into sealing engagement with each other.
Claim 7
Dependent Claim
82 words
In a sectional gasket, first and second sections each having an end with a recess and an end with a tongue, the tongue of one section being receivable in the recess of the other section with a side edge of the tongue in sealing engagement with a side edge of the recess, and a lip along said side edge of the tongue and a lip along said side edge of the recess, said lips being deformable into sealing engagement with each other.
Claim 8
Dependent Claim
82 words
In a sectional gasket, first and second sections each having an end with a recess and an end with a tongue, the tongue of one section being receivable in the recess of the other section with a side edge of the tongue in sealing engagement with a side edge of the recess, and a lip along said side edge of the tongue and a lip along said side edge of the recess, said lips being deformable into sealing engagement with each other.
Claim 9
Dependent Claim
46 words
A gasket in accordance with claim 6 in which each section has an edge completely surrounding the same and which includes said tongue and recess edges of the respective section, and the lip on each section extends completely around the section along the entire edge thereof.
Claim 10
Dependent Claim
30 words
The gasket of claim 7 in which each of said lips is of resilient material projecting from a face of the respective section and merges with the respective section edge.
Claim 11
Dependent Claim
86 words
In a sectional gasket, a first section having a tongue and a second section having a recess in which the tongue is received, said tongue having a pair of side edges having initial interference fits with a pair of parallel side edges of said recess, and one of said pair of side edges being of resilient material that is deformed into sealing engagement with the other pair of side edges, at least one of said sections comprising a rigid member having said resilient material mounted thereon.
Claim 12
Dependent Claim
86 words
In a sectional gasket, a first section having a tongue and a second section having a recess in which the tongue is received, said tongue having a pair of side edges having initial interference fits with a pair of parallel side edges of said recess, and one of said pair of side edges being of resilient material that is deformed into sealing engagement with the other pair of side edges, at least one of said sections comprising a rigid member having said resilient material mounted thereon.
Claim 13
Dependent Claim
18 words
The gasket of claim 9 in which both of said pairs of side edges are of resilient material.
Claim 14
Dependent Claim
37 words
The gasket of claim 9 in which at least one of the tongue side edges and the adjoining recess side edge has a lip adjacent thereto, and said lips are deformable into sealing engagement with each other.
Claim 15
Dependent Claim
41 words
The gasket of claim 9 in which each of said tongue and recess side edges has a lip adjacent thereto and the lips on the tongue side edges are deformable into engagement with the adjoining lip on the recess side edges.
Claim 16
Dependent Claim
13 words
The gasket of claim 9 in which said tongue side edges are parallel.
Claim 17
Dependent Claim
33 words
The gasket of claim 9 in which said first and second sections each comprise a rigid member having a tongue and recess and having elastomeric material mounted thereon to form said side edges.
Claim 18
Dependent Claim
90 words
In a sectional gasket first and second sections each having a core section of rigid material, each core having a tongue at one end that has a pair of side edges and having a recess at the other end having side edges, each of said edges being covered with resilient material, the tongue of one section being received in the recess of the other section with the resilient material on the side edges of the tongue in sealing engagement with the resilient material on the side edges of the recess.
Claim 19
Dependent Claim
90 words
In a sectional gasket first and second sections each having a core section of rigid material, each core having a tongue at one end that has a pair of side edges and having a recess at the other end having side edges, each of said edges being covered with resilient material, the tongue of one section being received in the recess of the other section with the resilient material on the side edges of the tongue in sealing engagement with the resilient material on the side edges of the recess.
Claim 20
Dependent Claim
33 words
The gasket of claim 15 in which the side edges of the recess are parallel and the resilient covering thereon is of substantially uniform thickness throughout the length of said recess side edges.
Claim 21
Dependent Claim
31 words
The gasket of claim 16 in which the tongue side edges are parallel and the resilient covering thereon is substantially uniform in thickness throughout the length of said tongue side edges.
Claim 22
Dependent Claim
25 words
