Abstract
Abstract A seal is provided for sealing first and second mating surfaces. The seal comprises a channel in the first surface with a first projection in the bottom of the channel projecting upward towards the first surface. A second projection projects from the second surface towards the first surface and the second projection is aligned with the channel in the first surface. A gasket is positioned between the first and second surfaces at least partially within the channel, the first and second projections contacting the gasket and deforming the gasket at the points of contact thereof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
176 words
A seal for sealing a two-member joint comprising: (a) a first planar surface on one of the members, (b) a second planar surface on the other of the members disposed adjacent to and normally spaced from the first planar surface, (c) a channel formed in one of the members in the planar surface thereof, the side walls of the channel being integral with the member and the surface, said side walls sloping outwardly such that the width of the base of the channel is narrower than the width of the opening of the channel, (d) a projection formed in alignment with and projecting within the channel on the adjacent planar surface, and (e) gasket means disposed in the channel and engaged by the projection to seal the joint at the first and second planar surfaces of the two respective members, wherein the width of the base of the channel is narrower than the width of the gasket means and the width of the opening of the channel is greater than the width of the gasket means.
Claim 2
Dependent Claim
176 words
A seal for sealing a two-member joint comprising: (a) a first planar surface on one of the members, (b) a second planar surface on the other of the members disposed adjacent to and normally spaced from the first planar surface, (c) a channel formed in one of the members in the planar surface thereof, the side walls of the channel being integral with the member and the surface, said side walls sloping outwardly such that the width of the base of the channel is narrower than the width of the opening of the channel, (d) a projection formed in alignment with and projecting within the channel on the adjacent planar surface, and (e) gasket means disposed in the channel and engaged by the projection to seal the joint at the first and second planar surfaces of the two respective members, wherein the width of the base of the channel is narrower than the width of the gasket means and the width of the opening of the channel is greater than the width of the gasket means.
Claim 3
Dependent Claim
26 words
The combination claimed in claim 1 wherein: (a) the channel formed in the first planar surface, and (b) the projection extending from the second planar surface.
Claim 4
Dependent Claim
51 words
The combination claimed in claim 2 wherein: (a) a projection formed in the channel extending in the direction of the second planar surface, and (b) the channel having a width greater than the distance separating the pair of projections to permit the gasket means to be solely entrapped within the channel.
Claim 5
Dependent Claim
57 words
The combination claimed in claim 2 wherein: (a) the channel having a base facing the second adjacent planar surface, and (b) the projection spaced from the base a distance less than the width of the channel to permit the gasket means to be entrapped solely within the channel to form the sealed joint between the two members.
Claim 6
Dependent Claim
32 words
The combination claimed in claim 1 wherein: (a) the gasket means having a cross-sectional area smaller than the cross-sectional area of the channel, and (b) the gasket means defines an "O" ring.
