Abstract

709,404. Pipe joints. LAMONT & CO., Ltd., J. H. Dec. 11, 1952, No. 31373/52. Class 99 (1). In a joint in which a flared pipe end 9 is compressed on to a tapered olive or spigot 8 by a nut 3 and backing ring 12, the nut is of the conventional form having flats between radial end faces of which one is formed by an internal flange 6 having an outwardly tapered bore 11, and the backing ring has inner and outer conical faces and an external radial flange 12a which engages a recess 5 so as to retain the ring in the nut. The device is also applicable to the type of joint in which a conical-ended sealing ring is compressed on a cylindrical pipe end. Specifications 395,536, 560,248, and 578,501 are referred to.
