This invention relates in general to a lighting fixture and has more particular reference "to a fixture combining the illuminating effects ,produced by the ordinary filament types of lamps and electrified gas filled tubing 1 f One of the principal objects of the invention is in the provisionof' a lighting fixture in which.

electrified gas filled tubing and electric filament lamps are combined'with decorative, reflecting and refracting media to produce new and striking illuminating. efiectsj for decorative and display PUI'POSBS.

A further 'obj ectof theinventioh is in the, provision of an electric fixture;v in which replaceable I units of gas filled tubingare; used. i

A further object 0;? thefinventionis' to produce. new and striking illuminative effects by the combining of electrified gas filled tubi and ordinary electric lamps with. reflecting and retracting mediums which are transparent,translucent. and

opaque and in which the elements may be plain,

a ing effects by varying the lighting elements which are receiving current. 7

Other objects of the invention will appear hereinafter, the accompanying drawing illustrating more or less diagrammatically a combination of elements for producing the desired effects.

In the accompanying drawing, Fig. l is an elevation with parts shown in section of a fixture embodying the principles of this invention; and

Fig. 2 is a sectional plan view of the fixture.

Electrified gas filled tubing is not now commonly used for lighting fixtures for decorative and illuminative purposes principally for the rea-- son that such tubing is neither designed nor intended to be supplied in replaceable units which may be readily applied to a lighting fixture of this type. Such tubes are used for signs, letters, and advertising and display purposes. One of the objections to the use of this tubing in electric fixtures has been that it is operated byan electric current of high voltage, requiring a transformer,

which is objectionable unless the fixture is made I complete in itself so that there is little or no v danger in its use.

' It heretofore been] considered impractical to' combine as filled tubing with the filament type of lam'ps'in an electric fixture because the tubing when lightedusually produces a highly co-1: or'ed' and attrac ye illumination which is not usually of pleasingqualijty for lighting purposes. li'rwvever,v byycombiningj'gas filled tubing. units which produce illumination of various colors with reflectors of metal and'glass and transparent and semietransparent globes or shades and electric lamps of the filament type which may be either plain or colored, fixtures of various designs imay beconstructed inlwhich theli'ghtin'g eifects produced by thecombinjatio'ns are'extremely attrac tive 'and' striking in appearance,and have suflicient illuminatio nfto produce a fixture which may be used in any" desiredlocation. 'In such a fixture the illumination maybe yaried by conncct- 'ing certain of 'the'jlighting' elements to different switcheswhich may be ohratedat will. In other, words, there may begas filledj tubes which produce different colorsandfilarnent lamps for" fdifierent colors all in the I same fixture. c'oufoining to pm; duce anilluminatihgeffect whichmayb'e greatly varied tosuit. various conditions.

i Referring now nior, p'arti ularly to} the o drawof glass or the like, either plain, frosted or'colored and although represented as being located below the other reflectors, lamps of different designs will have these reflecting and r'eiracting mediums dii-' ferently'located, of different shapes and sizes and a in different colors to produce fixtures of various types and designs.

The so-called central'structure is preferably composed of tubular or hollow metal parts I, 8 and 9 suitably connected together and providing mg a fixture :01. thependantor chandelier type t means for'carrying the reflectors and for covering and protecting the electricwiring.

A number of electric lamps It of the filament type are supportedby the central fixture support in any suitable manner as by means of short metalv fixture stems l l secured to and projecting from the tubular parts 8 and 9. These lamps It may be located within the bowl 5 or the reflector 6 where they are not ordinarily seen from below or they may project openly from a collar l2 in any desired location. I

Also carried by the collar l2 area number of sockets I 3 arranged in parallel pairs for receiving the extremities 14 of a'gas filled lighting tube l5 which is located immediately below the reflector shade 6 so that the color of the tube when lighted will beimparted to the shade 6 and the direct'light of the tube will also be available.

Another setof sockets I 6 is supported from the central support, as from the tubular member 8, the sockets being arranged in parallel vertical pairs to receive the terminals ll of a gas filled tube l8. These tubes may have any de.-, sired shape or design and as represented they have upper bendsl9 and 2!] representing them as dipping into or extending out of the reflectors 5 and 4. A portion of each of the-tubes I8 is located on the opposite side of the glass shad'eS and the illumination imparted to the shade by this tube is entirely different in character and. result from that imparted by the lower tubes l5.

In order to supply current at the proper voltage and to make the fixture as safe electrically as possible, a transformer 2| may be carried in the tubular portion 8 of the central support from whichconductors 22 lead through the sockets I3 and I6 to the terminals of the lighting tubes. By this construction and arrangement the transformer is locateddirectly in the'fixture and close to the tubes so that a minimum of wiring is required.

, With this, construction, combination and arrangementof parts it is possible to obtain a variety ofdirectindirect and semi-direct light ing by means of ordinary filament lamps and gas filled tubing lights; by properly connecting "the separate? elements through suitable wiring and switches, the various combinations of light ing efiects may be obtained from the same fixture, using each group of lamps or lights separately,

or in combination with all of the others or any group of them. In this manner a striking lighting effect may be produced for the tubing lights as now employed are highlycolored andwhen combined with the shades, reflectors and lights, of a. lighting fixture in which these parts may also be separately or differently colored, the

lighting effects are modified and produce fixtures of great beauty.

Lighting fixtures of this kind are particularly adapted for use in public places such as theatres, cafes, and halls where it is desired to produce a brilliant, attractive lighting effect, and at times to changethe lighting effect either as to predominant color for a short'interval, or to change the entire lighting eifect which may include re placing the tubes and lamps with those of a different color or design. With such a construction 'a great variety of changes can be made with the same fixture in a very short time and at a minimum of cost.

Even when the tubes are not lighted the effect I which they have is decorative because they may be colored and the lighting produced by the filament lamps is modified to the extent that they shine through or upon or in combination with theeolored efiect produced by the tubing.

We claim:

1. Ina lighting fixture comprising a support, reflectors carried thereby and spaced along the support, filament lampscarried by the support and arranged inside and outside of the reflectors for direct and indirect lighting, gas filled tubing lamps also carried by the support and disposed with portions on opposite sides of the reflectors for direct' and indirect lighting, and an electric transformer for the current for the tubing lamps also carried by the support close to the tubes and enclosed by at least one'of the reflectors.

2. In a lighting fixture, a support having a plurality of reflectors carried thereby, filament lamps carried 'by the support and arranged in side and outside the reflectors for direct and indirect lighting,v gas filled tubing lamp units also removablycarried by the support and interchangeably disposed inside and outside of the reflectors for direct and indirect lighting, the

tubing units being illuminated by the filament lamps to produce different lighting effects when the tubing units are illuminated and when they are not illuminated.
