13 Claims.

This invention relates in general to a lighting fixture combining the use of gas filled tubing and ordinary filament electric lamps and has more particular reference to a pedestal or floor lamp but may also be appliedtoan inverted type of pendant lamps or fixtures.

One of the principal objects of the invention is in the provision of a lighting fixture in which gas filled tubing is combined with filament electric l0 lamps to provide an improved type of electric lighting fixtures.

A further object of the invention is in the provision of a supporting stem for lighting fixtures which is illuminated byan electrified gas filled tubing.

A further object of the invention is in the provision of a floor lamp in which a transformer for a gas filled tubing lamp is combined in a floor supported lamp. 2

A still further object of the invention is in the provision of light reflecting tubing combined with a gas filled tubing light, the tubing light being either within or without the other tubing which is illuminated thereby to produce a more attractive lightingefiect.

A still further object of the invention is in the provision of a lighting fixture support in which glass and metal tubings are combined and secured together for producing novel lighting efiects, for

mutually strengthening each other, and for providing passageways for conductors, all for the purpose of producing a lighting fixture of novel type, design and combinations.

Other objects of the invention will appear hereinafter, the preferred construction and modifications thereof being illustrated in the accompanying drawing. In the drawing,

Fig. 1 is a sectional view of a lighting fixture in accordance with this invention; 2

Fig. 2 is a section taken on the line 2-2 of Fig.

Fig. 3 is a similar section of a modification; and Fig. 4 is another section of a modification.

45 In the ordinary type of floor lamp it is customary to support a shade at a distance from the floor or support by means of a hollow rod or stem through which the conductors extend for supplying current to the lamps. The supporting tube is usually plain and unattractive and of course has no lighting value.

The present invention proposes to utilizea gas filled tubing type of lamp for illuminating the supporting stem therebymaking itattractive in appearance either separately or. in combination with I filament lamps which are enclosed or covered by the shade. Thistype of supporting stem is capable of a great modification and variation by means of which entirely different and novel lighting efiects may be obtained.

Referring now more particularly to the drawing, a floor lamp is illustrated in Fig. 1 having a hollow metallic base portion 6 supported by legs I and with anupper shade or reflector 8 suitably supported in any well-known manner as from a central stem 9 and enclosing a number of electric lamps In of the filament type. The shade 8 may be of any suitable transparent, opaque or reflecting material of which such parts'are made.

Extending between the base and the shade 8 is a supporting standard comprising a central tube I I of transparent material such as glass providing a protected bore l 2 for a neonor gas filled tubing IS. The outer surface of the tube ll may be provided with fiutings I4 or other decorations and when the gas filled tubing is electrified a beautiful glow and illuminating efiect is produced by the tubing ll.

At intervals along the tubing I l are supporting rings I5 for solid and hollow rods [6 and I1, each 25 ring I5 having portions l8 for surrounding or engaging the rods and holding them in place. The rings themselves are held in place by screws l9 which are inserted through the ring l5 and through the solid rod I6, if desired, into receiving recesses 20 in the tube I l.

The supporting standard is secured to and upheld at its lower end by fastening devices 2| which extend through the rods l6 and upper fianges at the base 6, or by any other suitable connection, and at the upper end of the standard is a frame or receptacle 22 preferably of sheet metal, which may be secured at the upper ends of the'rods l6 and I! in any suitable manner as by means of threaded portions 23 and lock nuts 24 engaging the 40 inner and outer sides of the receptacle. This receptacle'provides a support for'the attachment of lamp brackets 25 and also for an upper socket 26 for the gas filled tubing l3. The central stem 9 for supporting the shade 8 may be attached to the top or cover 21 of the receptacle 22 and removable bodily with it if desired to uncover the receptacle.

At the lower end of the standard and within the base 6 is a lower socket 28 for the gas filled tubing l3. Also carried by the base 6 is an extension 29 for housing a transformer 30 for supplying current under high voltage to the sockets 26 and 28 for the gas filled tubing 13. This transformer receives current from the ordinary conductors 3| which supply current to the filament changeable.

lamps H], the conductors passing upwardly through one of the hollow tubes 1 l. A secondary or high voltage currentfrom the transformer is connected to the sockets 26 and 28 by means of conductors 32 and 33, one of which also extends through one of the hollow tubes to the upper socket 26. By separately controlling the filament lamps and the gas filled tubing entirely different lighting effects may be. produced and by making the gas filled tubing I3 separate from the hollow tubing II, the gas filled tubings for producing colors when electrified may be inter- Instead of having a supporting standard as shown in Figs. 1 and 2, various modifications may be employed for produQing, similar but different lighting effectss As shown in Fig 3,

a solid glassobar 35 havingfiuted or decorated edges 36 may be provided at'opposite sides, with gas filled tubings 31 and 38 for producing the same or different colors, these tubes being protected and partially enclosed by metallic shields 39 which confine the light "from the tubings toward the bar 35Qwhich will" receive, refiectand disperse the light therefrom in a highly attractive and pleasing mannena This arrangement provides spaces between thebar and the tubings for conductors 40 by means of which the upper lamps and sock-' ets aresupplied with current. r V r In the modifiedf form .of standard as shown in Fig. 4, three solid glass bars 42 partially enclose ,is made variable by variously lighting the tubes themselves and by interchangingthe tubes when desired. It should also be understood that a confining or strengthening ring similar to the supporting ring 15 may be provided atintervals for securing the various bars and tubes together thereby adding adec'orative effect;,preventing the parts from becoming, loose or' spaced apart throughout their length, and-also providing means for mutually strengthening and supporting the associated parts which .make up the standard or stem which constitutes this part of the fixture. The lighting transformer isincluded as a part of the fixture enclosed in the base and the sockets forqthe gas filled tubing are located in parallel relation one above the other so that this tubing may-be easily removed and interchanged. *Weclaimr' 1.
