Filed:

Mar 23, 2011

Appl. No.:

13/070015

Inventors:

Myron S. Worley - Middlebury IN, US

Assignee:

PRESS-SEAL GASKET CORPORATION - Fort Wayne IN

International Classification:

F16L 19/00
F16L 5/02

US Classification:

277314, 277602

Abstract:

An expansion ring assembly seals a gasket with respect to an annular wall of a rigid structure. The expansion ring assembly includes two arcuate expansion ring bands that cooperate to define a generally circular profile. At one side of the expansion ring assembly, a first pair of ends of the expansion ring bands overlap and include a ratcheting mechanism which allows the ring to incrementally expand but not to contract. At another location of the expansion ring assembly, a second pair of ends are joined by a drive mechanism for engaging and driving apart the opposing ends of an expansion ring to thereby non-incrementally expand the ring. The ratchet mechanism may be used to initially set and hold the expansion ring against a gasket in a desired position and to provide an initial expansion pressure, i.e., for a coarse adjustment. The drive mechanism may then be used to provide a final expansion pressure of the gasket, i.e., for a fine adjustment. Advantageously, the coarse adjustment followed by the final adjustment allows a user to quickly and precisely achieve a desired gasket pressure by manipulating the torque applied to the drive mechanism.

International Classification:

E06B 7/22
B29C 47/06

US Classification:

494791, 49506

Abstract:

A one-piece seal is used between the rear doors of a semi-trailer truck and the rear frame of the truck, the seal having a good compression set resistance. The seal is made from multiple extrusion members that are fused, welded, or otherwise integrally, monolithically connected at corner joints to form a central opening. The extrusion members have a sealing profile, or cross-section, that allows for the compression and deflection of a pair of sealing lobes to create inner and outer seals, respectively, between the trailer frame and the door structure at the rear of a semi-trailer truck, as well as between the doors themselves.

International Classification:

F16J 15/02
B23P 11/00

US Classification:

277607, 29428

Abstract:

An expansion mechanism of the type that may be used with a seal for sealing a connection about the upper end of a concrete structure, such as providing as seal across a manhole frame, optionally one or more spacer rings, and the upper end of a manhole chimney or riser, or which may be used with a seal for internally sealing a connection between a pair of pipes. The expansion mechanism includes a pair of ring portions and a pair of expansion mechanisms that include pivotal connections to the ring portions such that the assembly may be moved or folded between a folded configuration, in which the assembly has a reduced profile to allow the assembly to be moved into place at the sealing site, and a deployed configuration, in which the assembly has a cylindrical shape and is expandable to compress the seal against a cylindrical surface.
