Abstract

500,653. Two-part couplings. SAX & CO., Ltd., J., and ASTEN, T. A. June 27, 1938, No. 17940/37. [Class 38 (i)] The socket contacts of a wall socket are covered by a disc A biassed by a spring D to the closed position and located in a guide ring B attached to the front of the socket member and enclosed by a cover rim C that overlaps the periphery of the disc A., The disc is turned by means of the plug member and since there is no central pivot the friction at the periphery of the disc makes it difficult to turn by other means than the correct plug.
