UNITED STATES PATENT OFF-ICE INDIRECT LIGHTING camcn. Poey, Bays'ide, N. Y. assignor' to The Miller Company, Mel-idea, Conn., a corporation of Connecticut Application it... 31', 1:167, sci-n1 No. 16l,741

an ornamental cover and a light reflector for producing indirect lighting.

Other objects and advantages will hereinafter appear.

The accompanying drawing shows, for mirposes of illustrating the present invention. a selected? embodiment in which the invention may take form, it being understood that the drawing is illustrative of the invention rather than limiting the same. In the drawing: I 1 Figure 1 is a vertical sectional view of a pendant lighting fixture with parts in section;

Figure 2 is a top plan view with parts broken away to show interior construction Figure 3 is a wiring diagram; and Figure 4 is an outline view illustrating a lamp or torchere type of fixture embodying the present o invention. I

The suspension for the pendant type fixture is indicated at I II. It is provided with four down-' wardly extending tubular arms ll. These arms are threaded at the lower end to receive nuts 12. They pass through areflectlng plate It and the plate ll, whichsupports a transformer indicated at II. The lower ends of the arms II also pass through bracket straps ll, and-the assembly is clamped together by nuts I! threaded on to the i lower end of arms ll.

The straps "support upwardly opening lamp sockets", and these carry incandescent lamp bulbs ll, the necks of the bulbs passing down through apertures ll in the plate ll. ,As indicated in the drawing it is possible to support various size lamp bulbs from the lamp sockets.

The plate i! also carries an upwardly extending strap or bracket II adapted tosupporta horizontal lamp socket II. This socket carries it 5o mercury vapor lamp bulb 2!. The lower end of the, transformer II is provided with the usual crowfoot 2|, which supports a dependent stem II. This stem by means of an ornamental knob 2' supports a transformer cover 21. This cover 55 21 fits against three straps or arms I! carried by a plate 29. The'arms 2; support a louver ring, indicated at ill, and-an upwardly and outwardly flaring reflector ii, The upper ends of the arms I or straps Ilflt the periphery 32 of the-plate l3,

so as to hold the parts in aligmnent. 5

. The

fixture wires

33 and 34 are carried down through the tubular arms ii and are connected through aswitch 35 with the incandescent lamps i9. They are also connected through a switchindicated at 30 to the transformer l5, which in 10" turn is connected to the mercury vapor lamp 23. Where the organization is to be'used as a floor torchere, the upper suspension is omitted, and the entire structure suitably supported from a pedestal or post, such as indicated at 40 in Figured. a

It will be apparent from the foregoing that,

one .could operate either or both light sources, and that in either case a well directed flood of llght'is directed toward the ceiling. The lamp bulbs are all effectively'concealed by the reflector 2o ated, sufllcient light escapes from the necks of thebulbs and scatters around" underneath the plate I! to bring about an illumination of the lower surfaces of the reflector 3i and the louver 25 .30, this light escaping through the spaces below when the incandescent lamp bulbs are operthese elements. It is apparent that, within the scope of the invention, modifications and different. arrangements may be made other than is' herein disclosed, an

and the present disclosure is illustrative merely,

the invention comprehending all variations thereof.

Whatis claimed is:

' 1. An indirect lighting fixture comprising a 35 the upwardly opening sockets, the necks of the incandescent lamp bulbs being below the plate, and an outwardly and upwardly flaring reflector beyond the edge of the plate to screen all the bulbs and reflect light upwardly.

2. An indirect lighting fixture comprising a substantially horizontal reflecting plate having peripherally arranged bulb receiving openings, a horizontal lamp socket above the plate, a mercury vapor lamp bulb carried in the socketiand 5 so below the plate and wired to the said lamp disposed above the plate, a centrally disposed transformer secured below the plate and wired to the said lamp socket, a downwardly extending stem below the transformer, a plurality of upwardly opening lamp sockets supported outside the transformer and a substantial distance below the openings in the plate, incandescent lamp bulbs in the upwardly opening sockets, the necks of the incandescent lamp bulbs being below the plate, an outwardly and upwardly flaring reflector beyond the edge of the plate to screen all the bulbs and reflect light upwardly, and means for supporting the flaring reflector from the stem.

3. An indirect lighting fixture comprising a substantially horizontal reflecting plate, a horizontal lamp socket, a mercury vapor lamp bulb carried in the socket, and disposed above the plate, a centrally disposed transformer secured a,144,os1

socket, a plurality of upwardly opening lamp sockets supported below the plate and outside the transformer, incandescent lamp bulbs in the upwardly opening sockets, the outer portions .of the plate being apertured to accommodate the incandescent lamp bulbs, an outwardly and upwardly flaring reflector beyond the edge of the plate to screen all the bulbs and reflect light upwardly, downwardly and inwardly extending reflect light from the neck of the lamp bulb on to the outer surface of the flaring reflector.
