Abstract
Abstract A joint and a gasket therefor in which the gasket comprises a resilient member attached to an offset portion of a first rigid plate. A second rigid plate is adjacent the first plate and surrounds the resilient member but is unattached to either so that it may be reused with a new first plate and elastometric member if the latter becomes worn out or damaged.

Dependent Claim
76 words
A gasket comprising a plate of rigid material having an opening therethrough, said plate having a generally flat planar outer peripheral portion and an inclined portion that surrounds said opening and merges directly with said outer peripheral portion, and an elastomeric member attached to said inclined portion and located immediately adjacent said flat planar outer peripheral portion, said elastomeric member extending beyond said peripheral portion a greater distance in one axial direction than in the other.
Claim 13
Dependent Claim
76 words
A gasket comprising a plate of rigid material having an opening therethrough, said plate having a generally flat planar outer peripheral portion and an inclined portion that surrounds said opening and merges directly with said outer peripheral portion, and an elastomeric member attached to said inclined portion and located immediately adjacent said flat planar outer peripheral portion, said elastomeric member extending beyond said peripheral portion a greater distance in one axial direction than in the other.
Claim 14
Dependent Claim
22 words
