Abstract

225,276. Hough, Ltd., J. E., and Pleasance, F. W. Aug. 27, 1923. Grounding aerials. - A switch by which the aerial is earthed except when a plug is inserted to couple up a receiving set comprises a chambered block of insulating material a carrying two terminals b, c which are connected by a leaf spring f secured to one of them. The other terminal is connected to a bearing h by a plate g. A plug having concentric conducting members j, k may be inserted into the bearing h and the member k then engages the bent end of the spring and breaks the connection between the terminals b, c. A connection is established between the terminals b, c and the conductors of a twin lead l<2>, which are connected to the members j, k by terminals on an insulating plate i<1> carrying the plug members j, k and covered by an apertured cap i screwed on to the plate.
