Publication number: 20090060635Abstract: A combination sealing and restraint system for an as-cast ductile iron fitting is shown for both sealing and preventing separation of an iron pipe fitting and a mating male pipe. A ring-shaped body is installed within a mating groove provided in a mouth region of the as-cast fitting after the fitting has been cast at the manufacturing plant. The ring-shaped body carries a gripping member with teeth on an inner surface thereof which are initially angled away from an outer surface of a mating male pipe. The teeth are forced into engagement with the exterior surface of the mating male pipe as the pipe joint at the fitting is assembled. The teeth are oriented to allow movement of the male pipe in a first direction relative to an end opening of the fitting during assembly, but to resist movement in a opposite direction after the fitting joint has been assembled. The ring-shaped body also includes a relatively flexible portion formed of an elastomer which forms a sealing member with the mating male pipe.Type: ApplicationFiled: August 28, 2008Publication date: March 5, 2009Inventors: Jim Jones, Gerardo Darce, Randall Chinchilla, Bradford G.

Patent number: 7475918Abstract: A press fitting system for creating an unremovably sealed connection between smooth-ended pipes comprises at least one section that is embodied in a collar-type manner and at least one bead which is located on the terminal side of the collar-type section and accommodates at least one annular, rubber-elastic sealing element. The press fiting system is characterized by the fact that groove-shaped channels which communicate with each other like a maze in the unpressed state of the sealing element run through at least some areas of the surface of the sealing element, the channels being pressed against each other in an occluding manner when the sealing areas interrupted by the channels are in the pressed state.Type: GrantFiled: December 3, 2003Date of Patent: January 13, 2009Assignee: Kaimer GmbH & Co.

Patent number: 7434850Abstract: A bell and spigot coupling system is provided for joining corrugated plastic pipe which improves the coupling's sealing capability with increasing hydrostatic pressure, and causes a substantial component of the force generated therefrom to be absorbed axially through the coupled sections of adjoining pipe. The spigot end of one pipe which is received within a bell coupler for an adjoining pipe terminates in a small annular bed-forming rib which forms a gasket bed that holds a gasket compressed against a radially extending gasket sealing surface of the bell coupler. Inward protruding latches formed in the bell coupler engage the adjoining section of corrugated pipe to resist axial separation and hold the gasket compressed against the sealing surface of the bell coupler. The sealing surface of the bell coupler contours the spigot end of the adjoining pipe and forms radially constricting pathways at opposite sides of the gasket.Type: GrantFiled: September 30, 2005Date of Patent: October 14, 2008Assignee: Prinsco, Inc.Inventors: Jeremy N.

Publication number: 20080157524Abstract: A combination sealing and restraint system for an as-cast ductile iron fitting is shown for both sealing and preventing separation of an iron pipe fitting and a mating male pipe. A sealing gasket body is provided with a series of integrally formed gripping segments. The gripping segments have teeth on an inner surface which are initially angled away from an outer surface of a mating male pipe. The teeth are forced into engagement with the exterior surface of the mating male pipe as the pipe joint at the fitting is assembled. The teeth are oriented to allow movement of the male pipe in a first direction relative to an end opening of the fitting during assembly, but to resist movement in a opposite direction after the fitting joint has been assembled. The combination sealing and restraining system is installed in the annular groove of the as-cast iron fitting after the iron casting operation at the factory.Type: ApplicationFiled: February 27, 2008Publication date: July 3, 2008Inventors: Jim Jones, Bradford G.
