Abstract
432,440. Plug-and-socket couplings. CRABTREE, J. A., Endwood, Little Aston Park; Sutton Coldfield. Jan. 30, 1934, No. 3066. [Class 38 (i)] A sliding shield a which normally covers the socket tubes c is displaced against the action of springs g on the correct insertion of a plug, the two pins pressing equally upon the bevelled face a<3>, but an unbalanced pressure tilts the shield laterally about a rib e so that a lug f on the shield engages in the socket tube or against some other part and locks the shield. The shield is therefore not operable by a single pin. In a modification, Fig. 4 (not shown), the shield co-operates with a plug provided with two pins of different lengths and becomes locked if the plug is not properly presented.
