ELECTRIC-LIGHTING FIXTURE.

Application filed. July 23,

, in'a novel manner, and it relates more particularly to an electric light fixture'having a large incandescent central light enclosed completely within a translucent bowl, and

r a plurality of relatively smaller lights supported entirely by 'said bowl and surrounding said larger central light.

To the above ends my invention consists ofa novel construction of an electric light fixture wherein a relatively large central incandescent light is supported within a translucent glass bowl, which in connection with "an upper 'metallic holder therefor, forms a substantially complete enclosure for said incandescent light and a plurality of relatively smaller incandescent lights on the outside of saidbowl supported by annular portion of said bowl, and a pendant reflecting cylindrical surface integral wlth said bowl and adapted to diffuse the light of the central light and to reflect that of the outer shower lights.

My invention further consists of other novel features of construction in said electric light fixture whereby the sockets for said outer shower lights may be adequately and efioiently supported by the wall of said bowl, and without any undue strain on the glass wall of said bowl.

For the purpose of illustrating my invention I have shown in the accompanying drawings forms thereof which are at present preferred by me, since the same have been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangerncnt and organization of the instrumentalities as herein shown and described. Figure 1 represents a front elevation of an electric light fixture, embodying my invention.

Figure-2 represents a schematic sectional 1924-. serial No. 727,618.

View taken on line 22 of Figure 1, showing the arrangement of the lights.

Figure 3 represents a section on line 3-3 ofFigure 1. V

Figure 4 represents a section on line --4 of Figure 1.

Referring to the drawings Similar numerals of reference indicate corresponding parts.

1 designates a globe of my novel construction having an annular supporting flange 2, the curvilinear upper surface 3, and the substantially horizontal annular outer wall 4.

The bowl 1 may be supported by any con ventional support 5, shown inFigures 1 and 3, whether of the suspension type shown in the drawings, or of the rigidly attached type, such as a canopy. The incandescent light 6, preferably of the Mazda type, having a clear transparent glass end of a size of approxi mately 100 watts, is disposed substantially centrally of the bowl 1, and supported in the central socket 7, carried by the bowl support 5, so that the source of light, namely the filament 8, shall be substantially about on a level with the horizontal wall portion 4, as shown in Figure 3. The sockets9 for supporting the shower lights 10, are supported by the horizontal wall portion 4 of the bowl 1,

namely by passing through an aperture 11 provided for that purpose, in the horizontal wall portion 4. Themanner in which said Sockets 9 are secured is clearly shown inFigure 4, wherein the porcelain or other base 11 containing the threaded metallic shell 12, is

secured to the inner side of the horizontal wall 4, by means of the retainingcollar or lower socket member 13, also preferably of porcelain, and in threaded engagement to the metallic shell 12. For the purpose of eliminating any strain on the glass wall 4 at this point, the resilient rubber gaskets 14 and 15 are inter-imposed between the wall 4 and the shoulders 16 and 17 of the porcelain base 11 and the porcelain collar 13 respectively, and all clamped between said shoulders.

The pendant shower lights 10 are preferably of the Mazda type, and may be frosted or of other translucent glass of a size ofapproximately watts.

In order to diffuse the light from the central bulb 6 and also properly to reflect the light of the shower lights 10, there is provided a pendant cylindrical concaved reflect ing portion 18, integral with the bowl and having a concave vertical reflecting surface adapted to reflect the light from the pendant shower lights 10. The pendant cylindrical portion 18 being also of a translucent glass and having a reflecting outer surface, will serve the dual function of diffusing the transmitted light from the filament 8, within the bowl 1, and also of reflecting the light from the various outer pendant shower lights 10.

The lights of my novel electric light fixture may be connected to the same line so as to be illuminated simultaneously and controlled by the same switch. In the preferred embodiment of my invention, however, the central light 6 and the shower lights 10 are connected to two separate lines and controlled by two separate switches as indicated in Figure 2, so as to permit the illumination of either the central light or the shower lights separately at will, or the illumination of all the lights simultaneously.

By my novel electric light fixture described above, there is thus provided a novel combination of acentral diii'used light and plurality of shower lights, forming a single lighting unit; and necessitating only a single support for the entire combination, as a unit, which in addition to being extremely serviceable and efiicient as a lighting unit, under all conditions, also presents an unusually novel and attractive appearance.

It will now be apparent that I have devised a novel and useful construction in an electric lighting fixture which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have, in the present instance, shown and described preferred embodiments thereof which will give satisfactory and reliable results, it is to be understood that the same are susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Lettors Patent, is

1. An illuminating device of the character stated, comprising an integral glass bowl closed at the bottom and open at the top, said bowl including an upper portion composed of curvilinear and plain walls and a lower pendant portion of lesser diameter, formed integral therewith, a through opening in the plain wall of the upper portion of said bowl, an electric socket extending through said opening and supported entirely by said wall, adapted to receive an electric globe from without, said electric socket comprising an inner and an outer member, one of said members extending through said opening while the other of said members is detachably secured to the former member.

2. An illuminating device of the character stated, comprising an integral glass bowl closed at the bottom and open at the top, said bowl including an upper portion composed of curvilinear and plain walls and a lower pendant portion of lesser diameter, formed integral therewith, a plurality of through openings in the plain wall of the upper portion of said bowl, an electric socket in each of said openings and supported entirely by said wall, adapted to receive an electric globe from without, each of said electric sockets comprising an inner and an outer member, one of said members extending through one of said openings, while the other of said members is detachably secured to the former member.
