Abstract
Abstract An oil pan cover or the like and gasket assembly for juxtaposition with a member to be sealed thereby, the cover providing a surface defining a sealing flange adapted to confront the surface of a member to be sealed, the flange surface defining an elongated groove for receiving the gasket assembly. The groove is T-shaped and includes a first internal groove section and a second wider groove section intersecting the surface of the flange. The gasket assembly is T-shaped and has an elongated body generally complementary in configuration to the groove, and includes a first elongated elastomeric sealing section adapted to be positioned and compressed between the wider groove section and the member to provide a seal therebetween, and a second elastomeric rigidifying bead, the sealing section and the bead being integrally molded, and a reinforcing wire fast with the rigidifying bead to rigidify the elongated body.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
80 words
A gasket assembly comprising an elongated body having a first elongated elastomeric sealing section adapted to be positioned and compressed between an engine and a cover to provide a seal therebetween, a second elastomeric rigidifying bead, said section and bead being integrally molded, and said bead being disposed at an angle to said section, and a stiffening element fast with said rigidifying bead to rigidify said elongated body, said stiffening element being out of the zone of said sealing section.
Claim 2
Dependent Claim
80 words
A gasket assembly comprising an elongated body having a first elongated elastomeric sealing section adapted to be positioned and compressed between an engine and a cover to provide a seal therebetween, a second elastomeric rigidifying bead, said section and bead being integrally molded, and said bead being disposed at an angle to said section, and a stiffening element fast with said rigidifying bead to rigidify said elongated body, said stiffening element being out of the zone of said sealing section.
Claim 3
Dependent Claim
24 words
A gasket assembly in accordance with claim 1, and wherein said body is T-shaped in cross-section, said bead comprising the stem of the "T".
Claim 4
Dependent Claim
26 words
