Abstract

474,525. Two-part couplings. COOK, C. R. May 4, 1936, No. 12578. Addition to 414,057. [Class 38 (i)] The invention described in the parent Specification is applied to valve holders having the insulating support 1 made in one piece. The sockets which may be of the kind described in Specification 352,102 are modified to enable them to be inserted in clearance holes in the support and secured therein. The socket 2 has a square or other non-circular head 3 and a shoulder 4 formed on the resilient part of the socket and tapered downwardly so that it can be compressed resiliently when the socket is being inserted in the support. In a modification a detached collar 12, Fig. 4, which is resilient or deformable is forced into position on the socket after it has been inserted in the support. Instead of a coned metal ring, the collar 12 may be in the form of an open wire ring.
