Patent number: 9039045Abstract: An improved quick connect hose coupling for connecting a hose to a fixture has a hose stem portion including a hose insert portion, a fixture portion including a fixture connection portion, and a joinder portion. The joinder portion includes a male connection portion and a female connection portion. Each of the male connection portion and the female connection portion are adapted to join in a sealing and locking manner upon being pushed together. The coupling further includes threads and wrench mating flats adapted to disconnect the hose from the fixture. It is improved by the male connection portion being a unitary structure having a leading support cylindrical surface, a following support cylindrical surface, and a transition, surface intermediate therein between. The leading support cylindrical surface has a leading radius. The following support cylindrical surface has a following radius. The following radius is larger than the leading radius.Type: GrantFiled: March 16, 2006Date of Patent: May 26, 2015Assignee: Gates CorporationInventors: Adrian R. Cooper, Geoffrey R. Keast, Randall M. Leasure

Publication number: 20110138605Abstract: A tubing termination comprises a termination portion adapted to make a fluid connection and a tube attachment portion, adapted to receive a tube and to be crimped or swaged. The tube attachment portion comprises a retention mechanism that is adapted to be manipulated during crimping or swaging to bite the tube so as to lock the tube attachment portion relative to the tube. This retention mechanism may take the form of a deformable bite ring, a deflectable c-insert, irregularities defined on an inner surface of the tube attachment portion, and/or the like. The tube attachment portion also may include a resilient sealing mechanism adapted to provide a seal between the tube and the tube attachment portion, and thereby a fluid-tight connection between the tube and the termination portion.Type: ApplicationFiled: January 19, 2011Publication date: June 16, 2011Applicant: Gates CorporationInventors: Jonathan C. Swift, Todd A. Eyster, Geoffrey R. Keast, Donald R. Gilbreath

Patent number: 7533907Abstract: A coupling assembly includes a female coupler selectively interconnected to a male coupler to provide sealing engagement. In one embodiment, the female coupler and the male coupler are secured together by a pressure activated locking assembly which prevents disengagement of the male and female coupling until the internal pressure in the coupling is reduced to a predetermined level.Type: GrantFiled: March 10, 2006Date of Patent: May 19, 2009Assignee: The Gates Corporation IP Law Dept.Inventors: Jonathan C. Swift, Geoffrey R. Keast, Timothy G. Robinson, Stephen McGee

Patent number: 7469933Abstract: A coupling assembly is provided that generally includes a female coupling selectively interconnected to a male coupling to provide sealing engagement. In one embodiment, the female coupling and the male coupling are secured together by a mechanical locking mechanism that is disengaged with a release mechanism. To prevent inadvertent disengagement, a secondary locking device or spacer is provided which substantially prevents the release mechanism from disengaging the locking mechanism.Type: GrantFiled: March 9, 2006Date of Patent: December 30, 2008Assignee: The Gates CorporationInventors: Jonathan C.
