Abstract

324,788. Keyne, W. O., and Plessey Co., Ltd. Jan. 5, 1929. Vacuum tubes. - Each socket is connected to the base of a holder or adapter by a helical spring, within or upon which a length of flexible rubber is mounted to damp out vibrations. As shown a thin rubber sheath 20 is slipped over each helical spring socket 16 so as to surround the lower coils thereof. A sleeve 17, having an external hexagonal shape, houses the end coils and forms therewith a nut into which an extension 15 of a terminal leg 11 is screwed until a shoulder 18 abuts against a vulcanite disc 10. The coils of the spring connection are opened out slightly as shown to ensure flexibility. Screws may be used instead of terminal legs when mounting the sockets directly on a panel. Specification 251,397 is referred to.
