LG-ITING. FIXTURE.

Appiieaiion inea .Tuiy ze,

My invention relates to the art of illumination. and particularly to devices adapted to receive and position light sources and s urround them with reflecting and diffusing means to cause the light rays to be delivered in a ceitain definite manner.

My object is to construct a fixture carrying two light sources, su rounded by diffusing means combined with reflecting means, .to direct the rays from the light sources in dif- Y ferent directions and yet cause the two light sources to function together for producing the general effect desired in the illumination.

Mv inventionV consists of certain detailed construction hereinafter set forth, pointed out in iny claim, andvillustrated in the yaccompanying drawings, iii whicli- Fig. 1 shows a side elevation view vof my fixture, part of the globe being broken away to reveal the inner' construction; and

Fig. 2l shows, in reduced scale, a section taken on line 2-2 of Fig. 1.

Similar reference numerals refer to similar parts throughout the entire description.

Referring to the accompanying drawings, I employ a globe holder lfhattached, in the ordinary manner, to a chain Ahanger 11, or .a canopy. In the canopy is mounted an electric light socket 12, supplied with proper currentcarrying wires (not shown) The upper portion 13 ofthe globe, preferably constructed of diffusion glass, is secured to the globe holder in the usual manner. A metal ring lll is Y secured by straps 15 to a hiclrey 15 in the canopy 10, as shown. rlhis metal ring 14: en gages the lower edge of the globe portion l-3, and is provided with a cii'cuiiifereiitial flange 17, within which the lip of the lower portion 21 of the globe rests. A inet-'al strap 1SY eX- tends across the ringl 111, and is orificed to sup-- port a socket 19 which depends therefrom.

Supply wires 2O conduct current to this vsoclret 19, the said wires 2O obviously passing upwardly and through the hickey 16. ylhe lower portion 21 of my globe, also preferably formed of diffusion glass, is held in position by the flange 17 iii any ordinary manner, such as is illustrated at 22, and shown iii detail in Fig. 1. Electric light bulbs 23 anc 24s are mounted in the sockets 12 and 19 respectively. A concavo-convei; reflector 'is secured to the metal ring let and centrallypositioned with relation to the light sources 23 and 24. The upper face of the reflector 25 will receive 1%27.

rays from the light source 23and direct them insetti;

upwardly, and the lower face of said reflector will receive rays from the light source 211 and direct them downwardly and outwardly. It

is very important that the light sources 23 and y 24 be in proper vertical alignment, so that the cominoii reflector 25 may function to rovide an even and regular from each source. Y

in constructing lighting fixtures, the prob leiii 'of the illumination engineer is to utilize the light so that theinost effective distribution for the purpose in mind may be produced. ily fixture is designed to give a more or less coiicciniate'd delivery of diffused light upon` the working plane from the lower light source, and a full distribution of light over the ceiling' and in the corners of the room` from the upper light source. By properly aligning my two light sources, and using a divided globe with a concavo-convex reflector distribution of tie rays mounted between the globe portions to direct .f

'the light, I obtain, Vfrom Atwo independent light sources designed to function together for general room illumination, a inostisatisfactory distribution of light. ,Y

lnniy drawings Iliave illustrated a preferred construction, but it isobvious this is only one illustrationof how iiiyinventioii may be adapted for use, and l do not want to beliinited in the scope of my protect-ion, eX-r cept as set forth in the appended claim.

Having described iiiy invention, what I Y and desire to secure by United s jard as new, Stateslietters i)ateiit, is: y i

in a lighting fixture, the combination, with a canopy, of en electric lamp' socket depending therefron'i, an electric lamp mounted therein, a difl'usiiigglass shade detachably se'- cui'cd to said canopy and enclosing said lamp,

a reflector closing the bottom of said shade,

all of the rays from said lamp not passing directly through said shade being redirected by said reflector, whereby the ceiling and upper corners of the rooin are illuminated,l

there being a central opening in said reflector,

'an `electric lainp socket depending therefrom,
