Abstract

708,202. Pipe couplings. AVERY-HARDOLL, Ltd. Nov. 24, 1952 [Feb. 4, 1952], No. 2920/52. Addition to 691,568. Class 99 (1). In a disconnectible, valved, spigot-and-socket coupling according to the parent Specification, the groove 29 in the spigot member is of dovetail cross-section, the packing ring 30 being of such a crosssection that it is retained in the groove but stands slightly proud of the spigot surface so as to be compressed by the wall of the socket as coupling is effected. To avoid trapping of pressure fluid in the groove behind the ring passages 31, 32 lead to the exterior of the spigot on both sides of the ring. Specification 679,762 is referred to.
