Abstract

661,137. Pipe joints. BOYD LAMONT PATENTS, Ltd. Oct. 25, 1949 [Aug. 30, 1949; Aug. 31, 1949]. Nos. 22463/49 and 22613/49. Class 99 (i). In a coupling for pipes 1, 2 comprising union members 3, 4 threaded or welded thereon and means such as a nut 6 or a nut and bolt for urging the union members together, at least one of the union members has a deformable end portion comprising an annular undercut projection 8 having a curved outer surface for abutting the other union member to effect fluid-tight joint therewith when the union members are urged together. The co-operating surfaces of the union member 4 and the nut 6 may be spherical or spherical and conical respectively. The projection may overlie the bolt passing through the union members, Figs. 5 and 6 (not shown), which import an end thrust thereto on tightening. Two concentric projections may be positioned on either side of the bolts, Figs. 7-9 (not shown). Both union members may be provided with an opposed projection or projections.
