Patent number: 7789432Abstract: A coupling that can be easily and repeatedly rotationally adjusted after assembly and/or installation. The coupling can comprise a male part insertable into a female part to a first position whereat the male part is rotationally locked with respect to the female part. Upon further insertion of the male part into the female part to a second position, the male part is rotationally unlocked from the female part and the male part then can be rotated relative to the female part. Once rotational adjustment is complete, the male part can be returned to the locked position to rotationally lock the coupling.Type: GrantFiled: March 13, 2008Date of Patent: September 7, 2010Assignee: Parker-Hannifin CorporationInventors: Steven J. Dohm, Gregory Kreczko, Ronald A. Moner

Patent number: 7658420Abstract: A quick-connect coupling having a rotatable release member that is movable between a locked position whereat the plug-to-connect coupling is locked in a coupled state, and a release position whereat the quick-connect coupling can be decoupled. The coupling can be operated with one hand as the release member can remain in an unlocked position (e.g., the release position) when moved to such position and released.Type: GrantFiled: July 13, 2007Date of Patent: February 9, 2010Assignee: Parker-Hannifin CorporationInventors: Keith R.

Publication number: 20050253388Abstract: A fitting such as for coupling the end of a length of hose to another member. The fitting includes a generally annular, cylindrical shell for surrounding the hose end, and a tube which is insertable into the hose end. The shell is coaxially mounted onto the tube between a pair of beads which may be upset or otherwise formed into the tube. The shell may be provided as formed at the end thereof which is received over the tube as having an anvil-like portion of an increased wall thickness against which and the first bead the tube may be upset to form the second bead retaining the shell on the tube.Type: ApplicationFiled: July 20, 2005Publication date: November 17, 2005Inventors: Patrick Smith, Gregory Kreczko

Publication number: 20040145182Abstract: A coupling, comprised of a tube with an attached tubular shell, for attachment with external components. The tube has a first end, second end and a longitudinal bore extending therethrough. The tube further includes an intermediate portion between the first and second ends having spaced radially outwardly extending annular beads. The tubular shell has a first portion axially confined between the annular beads and has an inner surface with a first axial end and a second axial end, wherein one of the first and the second inner axial ends has a non-rounded shape. The shell has a second portion extending axially from the first portion to a free end and has an inner surface spaced radially and coaxially outwardly of the exterior of the tube second end to define an annular recess therebetween and is adapted to be inwardly deformed toward the tube second end.Type: ApplicationFiled: April 1, 2003Publication date: July 29, 2004Inventors: Patrick A.

Patent number: 5638869Abstract: An end fitting is secured to a flexible metal hose comprised of a corrugated tube enclosed in a tubular braid in a manner that provides a single weld operation. An end of the hose is cut to bring the tube and braid ends into alignment. Thereafter, an end fitting is moved over the hose end and radially swaged into gripping engagement with the hose. A circumferential deep penetration weld integrally secures all the components, namely, the tube, the braid, and the fitting.Type: GrantFiled: April 24, 1996Date of Patent: June 17, 1997Assignee: Swagelok Quick-Connect Co.Inventors: Stephen J.

Patent number: 5330235Abstract: A coupling assembly entirely formed from plastics material is provided for selectively connecting and disconnecting first and second fluid lines. A male coupling member includes an external groove that receives a radially inward extending shoulder of the sleeve. An external groove on a female coupling member is selectively engaged by latching tabs extending radially inward from the sleeve. The latching tabs are selectively pivoted radially outward through depression of release buttons. The pivoting action of the latching members is defined along a central portion in which circumferential strips undergo a twisting action. A ring may also be provided as an accessory to the coupling assembly for selectively maintaining the male and female members in coupled relation. The ring is adapted for movement between first and second positions. In the first position, movement of the latching tabs is prohibited by the ring. In the second position, the ring does not interfere with the movement of the latching tabs.Type: GrantFiled: June 16, 1992Date of Patent: July 19, 1994Assignee: Swagelok Quick-Connect Co.Inventors: Ross L.

Patent number: 4982761Abstract: A coupling comprises a hollow body with a valve supported therein to define an annular chamber for receiving a mating stem component. A slide sleeve is mounted for axial movement in the annular chamber to control flow past the valve. Carried on the slide sleeve is a wiper mounted for sliding movement and having an end face which generally fills the open end of the annular chamber. A pair of slide hooks act to engage the stem member and move the slide member to a closed position when the coupling is disconnected. The slide hooks extend through slots in the wiper and are held in engaged position in the slide sleeve by cooperating surfaces on the hooks and the wiper. A pair of opposed dog-type detent members are maintained in a radially outward position by the outer surface of the wiper when the coupling is disconnected.Type: GrantFiled: June 20, 1989Date of Patent: January 8, 1991Assignee: Swagelok-Quick Connect Co.Inventors: Gregory Kreczko, Ross L.
