Abstract
249,635. Simplex Conduits, Ltd., and McLoughlin, H. F. Feb. 4. 1925. Plug couplings combined with swifches; covers. -The socket part g for receiving a plug coupling i, and the tumbler switch c with which it is interlocked are secured to the inner side of a cover a of a wall box b. A slide f constrained between guides m is moved by the switch dolly d, and engages, when the the switch is " on," a neck on the earthing pin h, thus preventing removal of the plug. The part g is secured against the guides m by screws j tapped into the plate a, and when the plate a is of metal, the socket for the earthing pin h is connected to one of these screws and thus to the cover and the conduit installation. The switch c is fastened to the cover a by screws ra located in semi-circular grooves p and passing through perforated plates q into tapped bosses o on the cover a, the plates q being secured to the switch base by the bridge fastening screws. This method of attaching the switch ensures that the dolly d is earthed to the cover a.
