Abstract

957,232. Pipe joints. A.P.V. CO. Ltd. Jan. 25, 1963 [Feb. 16, 1962], No. 6150/62. Heading F2G. A pipe coupling device comprises a steel annulus 3 whose internal diameter is such as to pass over the end of a pipe section 1<SP>1</SP> and one or more transversely split steel rings 2<SP>1</SP> locatable between the pipe and the annulus 3 and receivable in a groove therein and having one or more edge or edges of sawtooth section each having an inclined surface 6 and a surface 7 normal to the axis of the ring, at least one inclined surface facing the direction of insertion of the pipe end into the coupling. There may be one ring with more than one protruding edge, as shown, or more than one ring each having one protruding edge, arranged and disposed in a variety of ways, as described in the Specification. When joining two pipes, a similar device is fitted on the end of the other pipe section and the two annuli are held together by a common union nut.
