Patent number: 7490866Abstract: An anchoring device for a pipe coupling including an annular channel of generally U-shaped cross-section. The channel has a web portion with flanges and projecting radially inwardly. A frusto-conical gripping ring is located in the channel with its outer edge inside the web portion adjacent one of the flanges and its inner edge adjacent the other flange and projecting inwardly beyond this latter flange. The annular channel forms an incomplete ring and is compressible circumferentially. The anchoring device is fitted inside a clamping device, which fits around a pipe coupling. The clamping device has a tensioning for tightening the clamping device around the pipe, compressing the annular channel and causing the inner edge of the frusto-conical gripping ring to engage the outer surface of the pipe and thus grip the pipe.Type: GrantFiled: February 20, 2003Date of Patent: February 17, 2009Assignee: Taylor Kerr (Couplings) LimitedInventors: Ian Richard Webb, Neil John Taylor

Publication number: 20080272595Abstract: A mechanical pipe coupling is disclosed having an arcuate band with first and second ends in facing relation. A hinge is positioned between the first and second ends allowing the ends to move relatively to one another. Connection members are mounted on the ends, and a spacer is positioned between the ends to maintain the ends in spaced apart relation sufficient to allow end portions of a pipe to be inserted between arcuate surfaces which extend radially inwardly from the band. The spacer is configured to allow for tightening of the connection members to draw the ends together and permit the arcuate surfaces to engage the outer surfaces of the pipe elements and form a joint.Type: ApplicationFiled: July 17, 2008Publication date: November 6, 2008Applicant: Victaulic CompanyInventors: John Gibb, Douglas R.

Patent number: 7425023Abstract: A profiled clamp with at least one profiled segment which extend successively in the circumferential direction of the clamp and are clamped by means of at least one clamping device. The profiled segments have a profile which in cross-section is essentially inversely trough-shaped or cup-shaped. When the clamp is clamped, flanges which are provided at the ends of two pipes to be connected by the clamp are pressed toward each other between diverging side walls of the profiled segments. Gaps with a bottom each are provided between adjacent profiled segments. In each gap is provided a resilient metal strip at a distance from the bottom of the gap which is greater than the thickness of the bottom of the profiled segments, wherein the metal strip extends transversely of the plane of the clamp, and wherein the metal strip is mounted through lateral arms of the metal strip at the bottom of the gap.Type: GrantFiled: October 14, 2005Date of Patent: September 16, 2008Assignee: NORMA Germany GmbHInventors: Günther Hartig, Steve Williams

Patent number: 7401819Abstract: A preassembled mechanical pipe coupling having spacers is disclosed. The coupling has a plurality of interconnectable segments that straddle the ends of pipe elements to be joined. The segments have arcuate surfaces that engage outer surfaces of the pipe elements. Spacers, positioned between the segments, maintain them in spaced apart relation sufficient to allow the pipe elements to be inserted between the segments. The segments have adjustably tightenable connection members for connecting the segments and drawing them to one another. When the connection members are tightened and the effect of the spacers is overcome, the arcuate surfaces are brought into engagement with the outer surfaces of the pipe elements.Type: GrantFiled: May 10, 2005Date of Patent: July 22, 2008Assignee: Victaulic CompanyInventors: John Gibb, Douglas R.

Patent number: 7393020Abstract: In a pipe connection, a first pipe has a first flange of sheet metal provided with a first wall connected circumferentially to the first pipe. A second pipe has an end section shaped as a second flange. A clamp engages across the first and second flanges and has conical sidewalls forcing the first and second flanges axially against one another when tightening the clamp. The first flange delimits together with the first pipe an annular chamber that is coaxial to the longitudinal pipe axis. The first flange has a second wall that is glidingly supported on a free end of the first pipe. A sheet metal sealing ring is positioned between the first and second flanges. It has an edge section that is bent back onto a remaining sealing ring section that has a corrugation projecting past the bent edge section in an untightened state of the clamp.Type: GrantFiled: October 14, 2005Date of Patent: July 1, 2008Assignee: NORMA Germany GmbHInventors: Günther Hartig, Steve Williams

Patent number: 7350833Abstract: A flanged joint system connects two pipes disposed along a common axis. A flange having a mating surface terminates each pipe. A gasket assembly comprising an outer annular, substantially rigid retaining ring and a peripheral alignment rim, an inner deformable annular sealing member is interposed between the mating surfaces of the flanges. The flanges and gasket assembly are aligned in mutually coaxial relationship by receipt of the flanges within the alignment rim. The flanges are clamped together with their mating surfaces in axially aligned, facing relationship. The retaining ring limits the impingement of the flanges and prevents overcompression of the deformable material. The joint is reliable and durable, and permits aseptic processing conditions to be maintained. Servicing and gasket replacement are readily accomplished.Type: GrantFiled: March 11, 2005Date of Patent: April 1, 2008Inventor: Louis C. Bongiorno

Patent number: 7341287Abstract: A deformable mechanical pipe coupling is disclosed. The coupling is formed from an arcuate band that surrounds and defines a central space. The band has first and second ends in facing relation. arcuate surfaces that engage outer surfaces of the pipe elements extend lengthwise along the band. The arcuate surfaces have radii of curvature greater than the radii of curvature of the pipe element outer surfaces, allowing pipe elements to be inserted within the central space. The band has adjustably tightenable connection members mounted at each end. When the connection members are tightened, the ends are drawn toward one another, and the arcuate surfaces on the band deform and conform to the radius of curvature of the outer surfaces of the pipe elements.Type: GrantFiled: May 11, 2005Date of Patent: March 11, 2008Assignee: Victaulic CompanyInventors: John Gibb, Douglas R.

Publication number: 20080048444Abstract: A pipe coupling for joining pipe elements end-to-end is disclosed. The pipe coupling is formed of segments attached to one another circumferentially straddling the pipe elements. The segments are formed from sub-sections connected to one another end-to-end. Each sub-section has a surface region disposed to engage the outer surfaces of the pipe elements. Each surface region has a different radius of curvature from a surface region on a neighboring sub-section. The radii are selected so that when the coupling segments are deformed around the pipe elements, portions of surface regions of selected sub-sections contact the pipe elements, while portions of surface regions of those sub-sections between the selected portions remain in spaced relation away from the pipe elements. A constant and minimal torque is required to bolt the segments together as a result.Type: ApplicationFiled: June 7, 2006Publication date: February 28, 2008Applicant: Victaulic CompanyInventors: Michael V.

Patent number: 7249790Abstract: A band clamp used to connect tubular bodies such as vehicle exhaust system components. The band clamp has a band extending from a first end to a second end and includes a pair of spaced ribs extending at least part way between the first and second ends. A tightening mechanism is connected to the band and includes two clamp members movable toward and away from each other for tightening and loosening of the band. The band clamp further includes a gasket located on an inner surface of the band between the ribs and extending between the first and second ends. The use of the ribs with the interposed gasket provides a mechanical interlock of the band clamp with the tubular bodies while providing a hermetic seal at the junction between the two bodies.Type: GrantFiled: April 12, 2005Date of Patent: July 31, 2007Assignee: Breeze-Torca Products, LLCInventors: Michael R.
