Abstract
463,915. Two - part couplings. BOLLINGHAUS, W. July 17, 1936, No. 19936. [Class 38 (i)] Relates to two-part couplings of the kind in which the sockets are provided with spring- controlled shutter means normally closing them, and automatically displaced by the insertion of the plug. A supporting plate 1, Figs. 2 and 3, carries a locking plate 2 and is arranged on. the inside of a cover 3. The plate 2 is slidable on the plate 1 and is maintained in position by a clamping plate 4, the parts 1, 2, 4 being secured together by a flared tubular member 5, which may also serve for the reception of the hold-down screw of the cap 3. Upon insertion. of the earthing pin 10 it contacts with an inclined surface of the plate 2 and slides the plate against the action of a medially disposed spring 12, into a position in which apertures 6 therein register with sockets 7 and the recess 8 registers with the socket 11 to permit the full insertion of the plug. The other end of the spring abuts on a block 13 on the underside of the plate 1. In a modification, Fig. 5, the sockets 16 are formed at the ends of conducting bridge pieces 18, and locking members 21 with chamfered surfaces 22 are held over them by springs 34 until the insertion of the plug slides them longitudinally.
