Abstract

787,440. Synthetic plastic pipes: pipe joints. EXTRUDEX, Ltd. Sept. 19, 1956 [Sept. 19, 1955], No. 26768/55. Classes 99(1) and 99(2). A pipe coupling comprises male and female synthetic plastic members having interengaging round, square or Acme threads. A pipe 11 made from unplasticized polyvinyl chloride has enlarged ends to receive a female member 14 with a square thread 15, and a male member 12 with a square thread 13 which extends approximately half its length and is the same in length as 14 so that when engaged a shoulder 16 will abut the end of the female member. The bore in the male part 12 is the same as that of the pipe so that when the pipes are joined the interior bore is smooth and continuous. The members 12, 14 may be made separately and secured in the pipe ends by adhesive or they may be formed integrally with the pipe. The screw threads may be discontinuous to provide quick connection.
