Patent number: 11181214Abstract: A pipe coupling including an externally threaded body and an internally threaded nut. The nut's outer end includes an outwardly converging internal circular surface and a spacer is co-operable with the nut and body. The coupling further includes an O-ring and a deformable gripping member. The gripping member has an internal surface with barbs extending radially inwardly therefrom. An end of a pipe is insertable through said gripping member, spacer and O-ring into the body. Tightening of the nut causes axial movement of said spacer, sealing engagement of said O-ring to the body and pipe, and radially inward deformation of said gripping member such that said barbs clamp the pipe. The diameter of the O-ring is greater than that of the spacer at points where it is secured before tightening of the nut and less than that of the spacer when the nut has been tightened.Type: GrantFiled: June 20, 2018Date of Patent: November 23, 2021Inventors: Geoffrey B. Puckett, Malcolm J. Pridham

Patent number: 7846365Abstract: A nut and tail assembly and method of manufacture including a nut having a first end and an inward flange at the other end, a longitudinal cylindrical hollow body having a first end and a second end at which is located an outstanding flange and a circular longitudinal sleeve. The sleeve extends along said sliding surface and has a flange at a first end abutting against the body flange. A stop is located between the ends of the body and defines a cavity sliding surface generally parallel to the longitudinal body between the stop and flange. The nut inward flange extends into the body cavity and is of large enough diameter to be able to slide on said body sliding surface, but small enough to be held within said cavity defined between said stop and sleeve flange. Projections on the sleeve flange assist in locating the sleeve relative to the nut during the moulding process.Type: GrantFiled: June 10, 2009Date of Patent: December 7, 2010Assignee: Philmac Pty LtdInventors: David Chelchowski, Geoffrey B.

Patent number: 7270351Abstract: A coupling assembly for plastic pipes including a nut, a body, a grip-ring, and a seal. The nut can engage the body through appropriate threads and includes a hooked projection having a sloping surface adapted to abut against and provide a force on a corresponding surface of the grip ring within the body. A pipe is inserted through the nut, grip-ring, and seal into the body. Tightening of the nut causes its sloped surface to engage and the grip ring to be forced both radially and longitudinally. Radial compression results in the grip-ring engaging the pipe whilst longitudinal forcing causes it to be forced into the body simultaneously abutting against and compressing the seal whilst dragging the pipe further into the body. The nut and the body may further have tapered surfaces that are brought together as the grip-ring is forced into the body. The physical connection between the body and the nut provides reinforcing for the nut, a feature especially useful when dealing with soft plastics.Type: GrantFiled: July 7, 2005Date of Patent: September 18, 2007Inventors: David Chelchowski, Geoffrey B. Puckett, Luke Raymond

Patent number: 7178838Abstract: A nut and tail assembly (10) and method of manufacture including a nut (12) having a first end and an inward flange (24) at the other end, a longitudinal cylindrical hollow body (14) having a first end and a second end at which is located an outstanding flange (40) and a circular longitudinal sleeve (16). The sleeve (16) extends along said sliding surface and has a flange (44) at a first end abutting against the body flange (24). A stop (34) is located between the ends of the body (14) and defines a cavity sliding surface generally parallel to the longitudinal body between the stop (34) and flange (44). The nut inward flange (24) extends into the body cavity and is of a large enough diameter to be able to slide on said body sliding surface but small enough to be held within said cavity defined between said stop (34) and sleeve flange (44). Projections (50) on the sleeve flange (44) assist in locating the sleeve (16) relative to the nut (12) during the moulding process.Type: GrantFiled: May 29, 2003Date of Patent: February 20, 2007Assignee: Philmac Pty LtdInventors: David Chelchowski, Geoffrey B.
