Patent ID: 8746747

Claim:
A pipe joint, said joint comprising: an extrudable adhesive that solidifies on curing or cooling; a first pipe having a socket with an inside diameter, where said socket has a substantially cylindrical wall with a plurality of ports, a mouth with a rim, a self-centering bottom with a seated gasket, and an inner annular channel in fluid communication with one or more of the ports; a second pipe having an insertion section with a squared end and a rolled groove, where said insertion section of the second pipe is held in compression against the gasket in the socket of the first pipe, said second pipe having an outside diameter that is less than the inside diameter of the socket, where the difference in diameters defines a coaxial cavity having a second width that is a bond line of the adhesive adhering the insertion section to the socket, and where the rolled groove of the second pipe is substantially opposing the inner annular channel of the socket, such that taken together the rolled groove and inner annular channel are in fluid communication with the coaxial cavity and function as a distribution channel for the adhesive while it is a liquid and that when it is a solid the distribution channel functions as a retaining ring preventing movement of the second pipe relative to the socket; and a flanged annular ring where said annular ring has an inside diameter that enables it to slide over the second pipe, an annular ring portion with a thickness that is comparable to the second width of the coaxial cavity and compressed into the cavity, and a flange portion with, a flanged width that is sufficient to cap the rim of the socket, wherein the annular ring portion comprises: an outside circular protrusion that frictionally engages the inside diameter of the socket of the first pipe; and an inside circular protrusion that frictionally engages the outside diameter of the second pipe; where the outside and the inside protrusions help hold the second pipe compressed against the seated gasket.
