Abstract

1,080,305. Pipe joints; clay pipes. HEPWORTH IRON CO. Ltd. Feb. 24. 1966 [March 13, 1965]. No. 10722/65. Headings F2G and F2P. Plain-ended vitrified clay pipes 1 of round cross-section are provided with endless strips 2 of resilient material secured close to the pipe ends and are joined by a resilient synthetic plastic sleeve 4 having integral internal peripheral ribs 5 adapted to sealingly engage the said strips. The internal diameter of the remainder of the sleeve, which may be of plasticized or unplasticized polyvinylchloride, polyethylene, or polypropylene, is such as to provide a clearance over the pipe ends to provide for flexibility of the joint. The peripheral strips, which may be of a rubberoid bituminous mastic, synthetic or natural rubber, or synthetic plastics, are cast, moulded, or otherwise secured to the exterior surfaces of the fired pipes, Fig. 4 (not shown), or in grooves 3 formed in the pipes prior to firing. The sleeve may be provided with a centralizing internal flange 7, or alternatively, Fig. 3 (not shown), depressions 8 for receiving the sleeve ribs may be formed in the peripheral strips to centralize the sleeve with respect to the pipe ends. In the embodiment of Fig. 3, the sleeve has a uniform wall thickness throughout and the grooves accommodating the strips are undercut. In a further modification, Fig. 5 (not shown), each end of the sleeve is formed with two ribs for making sealing engagement with the respective peripheral strip of the pipe end.
