member 266. The knob 266 is preferably made of insulating material. A'preferably annular tact member 264 that is connected to the otherend of the secondary winding 2l6 through a lead 266; The contact member '264 is secured -to the outer layer of insulating material 225 by a rivet provide electrical connections between each of those electrodes and their respective terminals 262 and 246. The tube 266 is preferably made of glass, and preferably contains 'ararefied gas to provide the desired color or illumination.

With particular reference to Fig.- '7, a sealed glow or discharge tube 286 has a substantially straight portion 282 and has a bend therein as at 284 with the remainder of the tube formed,

around the portion 282, preferably in a substantially conical spiral form. End portions 286 and .288 of the tube 286 are preferably formed so as to extend substantially parallel and in close proximity to each other. mounted in the portions 286 and 288 of the tube connecting leads 294 and 296 respectively,-electrically connected thereto in extending )through and sealed into the tube. The portions 286 and Electrodes 296 and 292 are 286, preferably near the ends thereof, and have v 288 of the tube are mounted in a preferably me- I tallic base 298, and the space 366 around the portions 286 and 288, and within the base 296 is preferably filled with a suitable sealing com-- pound or cement. The connecting lead 294 prefsoldering as -at.364. The connecting lead 296 is eleotrically'connected to a terminal 366, preferably by soldering as at 368, which terminalis insulatingly secured to the base 298 through an insulating member 3l6.' The terminal 366 is .mounted inan aperture 312 in the insulating member 3l6, and secured therein by riveting or rolling the edge thereof as at 369, or by other erably extends through an aperture 362 inthe base 298 and is electrically connected thereto by suitable fastening means. The insulating member 3l6 extends into an aperture 3 in the base 298, and has a shoulder portion 3| 6 that rests against the inner surface of the base 298. The base 298 preferably has threads formed thereon, as at .3l 8, to adapt the base to be screwed into a suitable receptacle. The tube 286 is preferably made of glass, and has a-rarefied gas therein that provides the desired color or illumination, and the portion 288 of the tube is preferably offset from the portion 282 in a direction away from the portion'286 so as to provide a better balance and supportfor the tube in the base 298.

In the operation of these discharge tubes, the terminals thereof are connected to-a source of potential sufflciently high to cause a discharge or glow therein. The tubes are preferably of a type having the air pumped therefrom so as to' produce a vacuum therein, and which after evacuation have any suitable gas, such as neon or argon, introduced therein to produce the desired color or illumination. In tubes such as those shown in Figs. 1 and 2, the candle and flame portions thereof preferably have difierent kinds of gas therein toproduce different colors in those portions. The form shown in Fig. 2 requires a somewhat higher terminal voltage since the discharge -cap in the form shown in Fig. 2 is substantially twice as long as that of the form shown in Fig. 1.

In the form shown in Fig. 3, the luminous device operates in a manner similar to the other forms shown. However, it is particularly adapted to be covered by a suitable cover such as I54, which cover is preferably frosted or'has a coating thereon to diffuse the light. The diffusing coating or surface may also act as a color filter to produce a desired and novel color effect.

The base shown in Fig. 3 is adapted to fit a base such as that illustrated on the luminous devices of Figs. 3, 4 and 5. However, it can, very Well, be adapted to receive luminous devices having bases such as those shown on the luminous devices in Figs. 1 and 2. This base provides a housing for the transformer that provides the high voltage for the luminous device from a usual alternating current source, as well as a support for the luminous device.

The devices shown in Figs. 4 and5 have a plurality of discharge departments provided by the diilerent sealed tubes, and are preferably adapted to be utilized with a cover such as I54- of Fig. 3.

The different discharge compartments of these devices preferably contain different kinds of gases so as to produce a novel color effect, particularly when the colors are diffused or filtered by a coating on the cover. The tube shown in Fig. 4 requires a greater terminalvoltage due to the added discharge path through the tube I60 and tip I72.

Electrodes such as I96 in Figs. 4 and 5 are preferable when it is desirable to have the discharge go clear to the end of the tube in which the electrode is mounted. The insulating coating I98 on the outer surface of the electrode causes the .discharge to follow around the outer surface of the electrode to the inner surface thereof, and thereby causes the discharge to go substantially to the end of the tube.

The forms shown in Figs. 6 and 7 are preferably adapted to be used where more illumination is desired. The unit shown in Fig. 6 provides a luminous device complete with a step-up transformer therefor, so that the base thereof may be screwed into a suitable receptacle and operated by connection to a conventional source of alternating current. The luminous device may be removed from the transformer by removing the screw 254 and cap 250, and slipping the luminous device axially from the transformer. The knob 256 on the screw .254 is preferably made of insulating material so that it may be touched without danger of shock, and the cap 250'is preferably made of insulating material, and preferably covers the terminal-member 262. The form of unit shown in Fig. 6 is particularly adaptable- From the foregoing description of the structure and operation of the luminous devices herein described and shown, it is apparent that in at least one aspect the present invention comprises a luminous device comprising a substantially tubular insulating barrier wall 8 in Figs. 1 and 2 and ISO of Fig. 4, a tipportion Ii 01' Figs. 1 and 2 and I12 of Fig. 4 covering the end of the barrier wall and sealed thereto to provide a discharge chamber, means' l of Figs. 1 and 2 and I82, I84 or I85 of Fig. 4 providing a second discharge chamber surrounding said barrier wall, an electrode 24 and I4 of Fig. 1, 46 and I4 of Fig. '2 and I64 and I96 of Fig. 4, in each of said discharge chambers, means 26 and 28 of Fig. 1, 26 and 28 of Fig. 2 and 32 and 36 of Fig. 4 for making electrical connections to the electrodes, and means 38, 40 and 42 of Fig. l, 52 of Fig. 2 and I18, I80 and 200 of Fig. 4 for electrically conmeeting the discharge chambers.
