Abstract

1,175,503. Pipe couplings. BARTOL PLASTICS Ltd. 4 Feb., 1969 [14 Feb., 1968; 11 March, 1968], Nos. 7174/68 and 11658/68. Headings F2G and F2P. A synthetic plastics pipe coupling socket has an end portion 4 of larger internal and external diameter than the main length of the socket and an integral rib 5 projects inwardly of that portion for the retention of a synthetic plastics ring 6 which extends axially less than the length of the inside of the enlarged portion and forms with the inner end thereof an inwardly-facing annular recess in which is housed at least one sealing ring 7 for making sealing contact around the periphery of a pipe inserted into the socket. The lip 5 may be spaced from the outer end of the socket and the ring 6 be provided with an external groove located over the rib, and there may be two sealing rings 7 separated by a further ring 6. The socket may be integral with a main length of pipe or force fitted or secured by adhesive or heat or solvent cement welding on to one end of a synthetic plastics pipe or a clayware pipe. A socket may be formed at each end of a sleeve when the latter is provided at the mid-length thereof with one or more internal projections or a flange, or is constricted internally to less than the outside diameter of the pipes to be fitted into the sockets. The socket may be moulded with or without the lip 5, the lip, in the latter case, being formed subsequently.
