  • Publication number: 20190112868
    Abstract: A railcar door sealing gasket includes a bulb body secured along one of a door jamb stop surface or a door perimeter stop surface. The bulb body is integrally formed by a tubular sleeve internally separated with a wall into interior and exterior elongate channels. The separating wall is formed with pair of planar walls extending at an angle with respect to each other from the sleeve to a crest towards the interior channel. When the gasket is compressed between the door and jamb stop surfaces, the sleeve portion adjacent the exterior channel is forced against and forms a seal along one of the jamb stop surface or door stop surface, and the separating wall folds along the crest forcing the sleeve portion adjacent the interior channel against and forms a seal along a door perimeter surface extending at an angle from the door stop surface.

  • Patent number: 8910950
    Abstract: A sealing gasket that provides a seal between two members. The gasket includes a base at one end of the gasket and a gutter-forming surface at the opposite other end of the gasket. There is a pair of sides that join the one end and the opposite other end of the gasket. The sealing gasket is movable between a compressed condition wherein the gasket provides a seal between the two members and an uncompressed condition wherein the gasket does not provide a seal between the two members. When the gasket is in the compressed condition, the gutter-forming surface deforms to form a gutter along the one end of the gasket.

  • Patent number: 6439132
    Abstract: A gasket for a steel coil railroad car wherein the gasket is contained within a U-shaped channel in the coil cover. The gasket includes a base which has a mediate section which joins opposite flanges and a bulbous portion which defines a volume. The bulbous portion has a mediate flat section that joins opposite arcuate sections. The mediate section of the base is thicker than the arcuate sections and the flat section of the bulbous portion. The gasket is retained in the U-shaped channel in such a fashion that the base contacts the mediate portion of the U-shaped channel. The gasket is compressible upon the engagement of the gasket with the railroad car so as to form a seal between the coil cover and the railroad car.

  • Patent number: 5829358
    Abstract: A gasket assembly for sealing between a gate assembly and the bottom opening of a railroad hopper car wherein the gate assembly has a peripheral flange, and a hopper car flange surrounds the bottom opening of the railroad hopper car. The gasket includes a central band with an interior edge and exterior edge. The central band is made of a relatively rigid material. The central band contains a plurality of holes therein. An interior band of relatively softer material is bonded to the central band adjacent to the interior edge thereof. An exterior band of relatively softer material is bonded to the central band adjacent to the exterior edge thereof. Upon the assembly of the gate assembly to the bottom opening of the railroad hopper car, the interior band and the exterior band are subjected to a compressive force wherein the extent of the deformation of the interior band and the exterior band being limited by portions of the central band to which the interior band and the exterior band are bonded.

  • Patent number: 5586772
    Abstract: A gasket assembly includes an elongate flexible seal having opposite top and bottom edges. A portion of the seal adjacent to the top edge presenting a generally bulbous configuration. Another portion of the seal adjacent to the top edge presents a generally planar configuration. The bottom edge of the seal contains a channel. A rigid support member has a top portion which is received within the channel of the seal.
