Definitions

  • My present invention relates to supports for electric discharge devices andmore particularly to a support and shielding means adapts to. prevent the transmission of external vibrations to the electrodes of dischar e devices.
  • Vi rations transmitted to a discharge device tend to change the space relation of the electrodes mounted therein.
  • Such chan es produce variations in the output'of the isvcharge device and when the device is employed in connection with reproducing apparatus such as loud speakers and the like, seriously interfere with the operation of the reproducing apparatus and tend to make the signals reproduced thereby unintelligible.
  • a socket adapted to support a discharge device is mounted in a standard base, or cup-shaped member, in such a way that vibrations cannot be transmitted through the socket member to the electrodes of the discharge device.
  • a shielding means is provided which completely surrounds the discharge device and is ada ted to absorb any sound waves which woul ordinaril be transmitted to the glass enclosure of the ischa'rge device.
  • Fig. 1 is a cross sectional view of the support and shielding means, the discharge device being shown in elevation;
  • Fig. 2 is an exploded view of the support and shielding means for the discharge device;
  • F1 3 is a plan view of the standard base mem er with the socket for the discharge device mounted therein.
  • I have indicated at 1 an insulating cup-shaped member or base of standard form which is provided with four hollow terminals 2.
  • each spring 7 is inserted in base 1 and supports the socket member 3 therein.
  • Each spring is electrically connected at one end to one of the hollow terminals 2 and at the other end to a metallic member 8 mounted in socket 3.
  • a portion of each member 8 is bent outward- 1y, as indicated at 9, and soldered to the upper portion of spring 7.
  • 'Base 1 is provided on its periphery with a plurality of relatively large openings 10 and a projecting portion 11, as indicated in Figs. 2 and 3.
  • the lower ends of the s rings 7 are first soldered to the hollow terminals 2.
  • Pins 12 are then inserted through openings 10 and driven into the lower portion 5 of the socket member 3 and thereafter serve to limit the longitudinal movement of the socket member in the base 1.
  • a tube or discharge device 13 is inserted in socket member 3 the latter member is depressed until the pins 12 engage the lower portions of openings 10, after which the tube may be firmly inserted into the socket.
  • pins 12 engage the upper portion of openings 10 and permit removal of the tube without causing any distortion or damage to the spring supports.
  • the interior of the cap is provided with a heavy felt lining 16 which effectively prevents any transmission of vibrations to the glass wall of the discharge device 13.
  • the cap is slidably mounted upon and snugly fits the open end of the base 1, the depending fingers being so spaced as to accommodate the projecting pins 12.
  • the projecting portion 11 on base 1 engages one of the openings between fingers 15 and serves as a guide for the cap 14.
  • Any vibrations striking cap 14 are either absorbed in the felt lining or are transmitted to the base 1 and absorbed in the spring supports 7.
  • the discharge device 10 While the springs or flexible supporting is therefore completely shielded from all forms of external vibrations, thus providing a discharge device in which the space relation of the electrodes is maintained substantially constant.
  • a cup-shaped member provided with a plurality of projecting terminals, a socket flexibly mounted in said member and adapted to support an electric discharge device, means electrically connecting said socket and terminals, and a cap mounted on the cup-shaped member and adapted to substantially enclose said electric discharge device, said cap being provided with means adapted to substantially prevent transmission of vibrations therethrough.
  • a cup-shaped member provided with a plurality of projecting terminals, a socket flexibly mounted in said member and adapted to support an electric discharge devicc, means electrically connecting the socket and terminals, and a cap slidably engaging the cup-shaped member and substantially enclosing said electric device to thereby prevent the transmission of external vibrations to said device.
