Abstract: 809,106. Tube &c. couplings. ELECTROLUX CORPORATION. July 8, 1957 [July 17, 1956], No. 21514/57. Class 99(1). A coupling comprises a socket 10 having a resilient warped locking ring 18 with one part angularly displaced relatively to its other part whereby its internal diameter is reduced to cause it to grip the outer surface of a spigot 30, the coupling being released by a handle 20 which urges the ring parts towards the same plane. The inner diameter of the socket 10 is enlarged at the end so as to provide a shoulder 12 from which extends an open ended slot 14 having a smaller slot 16 diametrically opposite. The handle 20 extends from an offset portion 21 on the ring 18 and has a tab 22 diametrically opposite. The ring 18 may be of spring steel, is preformed and is secured in the member 10, the tab 22 being received in slot 16 and the handle 20 extending through the slot 14. A cap 24 closes the slot 14 and retains the ring 18 so that its lower half lies close to the shoulder 12 and the upper half extends towards the outward end. The inner bore 28 of the socket 10 is tapered and receives a corresponding tapered part 32 of the spigot 30 which when inserted causes the upper part of the ring 18 to be bent towards the plane of the lower part increasing its internal diameter to permit further entry. When the part 32 is seated in the part 28 the ring tends to return to its original position creating substantial friction on the outer surface of the part 30 which is increased as the part tends to be withdrawn since the internal diameter of the ring 18 tends also to be decreased thus preventing withdrawal. The parts may be disconnected by moving the handle 20 so as to flatten the ring 18. In modifications, Figs. 9, 10 (not shown) the handle of the ring may extend straight out, in Figs. 11-17 (not shown) the locking ring is released by a rotatable cam secured in the enlarged end of the socket, and, in Figs. 18-32 (not shown) a pair of oppositely warped locking rings are provided which are released by a double faced cam.
