Summary:1,161,135. Recessed socket; collapsible mould. OSMA PLASTICS Ltd. 29 July, 1968 [12 Sept., 1967], No. 41505/67. Heading B5A. [Also in Division F2] A socket having an interior, peripheral recess is made using a mould core defining the interior of the socket and a multipart mould member defining the interior of the recess and located on the core, wherein, after moulding, the core is withdrawn and the multipart member collapsed and the parts thereof individually removed. As shown in Fig. 2, the multipart member comprises three parts 13-15, together forming an annulus, two parts abutting on one end face 16, the other part 15 lying between the opposite end faces 17 which diverge in a direction towards the interior of the socket. They may be held together and to the core by a threaded stud 19 having a winged end 20. The socket may be moulded of glass fibre reinforced polyester by winding spun glass strands around the multipart member and treating with polyester and applying glass mats to the core and also treating this part with polyester. The recess may have two adjacent sections of different diameter, the larger housing a sealing ring (5, Fig. 1, not shown), the smaller a lip 9 which forms a seal against a pipe spigot inserted into the socket.
