LIGHTING FIXTURE.

Application filed August 17, 1926. Serial No. 129,871.

My invention relates to the artof illumination, and particularly to devices adapted to receive a light source and distribute the rays therefrom indesired and predetermined manner.

The object of my invention is to provide a lighting fixture adapted to function in a manner, not only to give off a maximum light efficiency from the source, but also to distribute the rays in such way as to produce a maxlmum efficiency for the general purpose for which it is adapted.

Combined with the above purpose, it is my object to produce a device having substantially all of the advantages of the so-called enclosed glass units, but at the same time to a leave the neck of the lamp entirely exposed, so that there is no modifying means whatsoever between the neck of thelamp and the side walls of the room, above the plane of the reflector which I use.

A further object is to produce, in a lighting fixture of the type above set forth, a combination support for both a reflector and a globe, the support being spaced, or suspended, from the socket support, so as to leave the neck of the lamp used in the fixture entirelyexposed.

A further object is to produce such a fixture from a combination of elements, associated together, Whichis adapted for practicability (for compactness) in shipping, installing, and maintaining.

A further, and very important, object is to provide an enclosed incandescent lighting unit, in which there will be a proper aircirculation at the neck and the base of the lamp.

My invention consists of certain details of construction, hereinafter set forth, pointed out in my claim, and illustrated in the accompanying drawing, in which Fig. 1 shows a side elevation of my device, a part of the same being in section and Fig. 2 shows a bottom view of my device, a part of the same being broken away.

In the accompanying drawing, reference numeral 10 is used to indicate a support for V a socket 11, which receives a lamp 12. This support 10 is secured to any ordinary junction box in any desired manner, either by suspension means to the ceiling, or direct to the ceiling, or to a canopy interposed between, the essential feature only being that there is a support for socket 11.

The numeral 13 indicates a reflector, preferably circular in conformation and orificed through of the neck 15 of preferably by means of metal strips 16, but

it is obvious any form may be employedfor securing the reflector 13. to the socket support 10, just so that it provides for positioning and suspending the reflector 13 at substantially the desired distance below the socket support 10. j

The reflector 13 is also provided with means 17 to support the globe 18. In the drawing, this means 17 is shown in a specific manner, but it-is understood that any satisfactory securing means may be employed, the function of the reflector 13 being also intended to include the function of securing the globe 18. In the drawing, I'have shown a diffusion glass cup 19, mounted above the neck 15 of the lamp 12, the function of this cup 19 being to diffuse the rays of light immediately above the lamp 12, room of bright circular rings which might othewise be projected thereon. However.

in some instances be desired. 7 The reflector 13, as shown in its combination with the other elements, closesthe top of the globe 18, except for that orifice 14 through which the neck 15 of the lamp 12 projects. This orifice 14 is preferably wide enough to leave a small space between the neck 15 of the lamp 12 and the edge of the orifice 14, and

this is not necessary nor essential, but might .this assists in providing for proper venti1a-,

tion for the lamp.

My fixture combines the following elements: A reflector, a globe depending therefrom, a. support receiving and positioning both the reflector and the globe in proper relationship, an orifice in the central part of the reflector, a lamp, projected upwardly through the orifice in the reflector to a seat in a socket, the reflector be ing spaced from the socket and permanently positioned thereto. a

In my drawing,I have shown specified means for accomplishing these purposes,but I want it understood that different means may be employed without at all varying my invention, which, stripped to its basicintent, is to produce a lighting fixture in which a reflector anda globe are spaced below a socket and properly supported, the neck of the lamp, above the reflector, being left exposed so that light rays emanating therefrom willnot be;

so as to relieve the ceiling of the the neck of which is decreased in'eflleiency by absorption in passing through any modifying means, but will reflector will preferably, be of opaque ma 1 terial, but this isnot strictly"essential- Having thus 7 described my invention; what I claim, and desireto seeure'by Letters Patent o'f 'the United States is:

In a; lighting fixture the combination of a socket, ecover therefor, a bulb in the socket, a shallow diff sing cup between the bulb and cover, supporting arms secured to the cover and extending below the diffusing cup, an an- 7 nular reflector on the arms, said reflectorclosely surrounding the neck of the bulb and a globe supported'from the reflector surrounding the lower part of the bulb'below there- EDWI'N'F.
