Patent ID: 7341285

Claim:
A pipe joint, said joint comprising: an extrudable adhesive that solidifies on being extruded; a first pipe having a socket with an inside diameter, where said socket has a mouth that is an open end of the socket, a self-centering bottom that is an opposing seating end of the socket, and a substantially cylindrical wall with an inlet, an outlet, and, an inner annular channel; a second pipe having an insertion section with an end and an outer annular channel, where said insertion section of the second pipe is inserted into 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 gap and where the outer annular channel of the second pipe lines up with the inner annular channel of the second pipe, the aligned channels defining an interlocking keyway filled with the extrudable adhesive; a flanged annular ring, where said annular ring has an inside diameter that enables it to slide over the second pipe and a thickness that is comparable to the gap, and where the annular ring has a flange with a width that is sufficient to cap the mouth of the socket; a temporary clamp that secures the insertion end, the socket and the flanged annular ring as the adhesive is extruded into the joint and until the adhesive has solidified; and wherein, when said pipe joint is fully formed when the extrudable adhesive, after being injected into the joint substantially filling the gap and the interlocking keyway, solidifies, therein forming a mechanical key in the interlocking keyway.
