7 Claims. (01. 240- 78) This invention relates to improvements in lighting fixtures and more particularly, in ceiling lighting fixtures of the indirect lighting type.

V The general object of the present invention is the provision of an improved-ceiling lighting fixture of the type specified, said fixture being of simple and inexpensive construction,of easily assembled and disassembled parts, and of particularly pleasing and attractive appearance.

A more specific object of the present inven-' tion is the provision of an improved ceiling lighting fixture of the type specified, which fixture includes an opaque main reflector and an opaque supplemental reflector, said supplemental reflector having for its purpose the illumination of the outer surface of said main reflector. Due to a colored glass disc with which the present fixture is removably provided, the illuminated outer surface of said main reflector is correspondingly colored, and by having a set of differently colored discs for selective use with thepresent lighting fixture, the illuminated outer surface of said main reflector can begiven any desired color. With the present lighting fixture, therefore, variously colored and exceedingly beautiful lighting effects can be easily, conveniently and economically obtained, allas will more fully hereinafter appear. I In one embodiment of the present invention, namely, in the one here illustratedand described,

two supplemental reflectors are used, one to illuminate the outer surface of the main reflector, as heretofore referred to, and the other to i1- luminate the outer surface of said first men tioned supplemental'reflector. Due to the colored disc heretofore referred to, the illumination of the outer surfaces of said main reflector and said supplemental reflector is of colored character, although it is to be understood that the use of such a colored disc is not essential to the use of the present lighting fixture and hence said disc may be dispensed with, if and when desired.

As will be apparent hereinafter, a most attractive lighting fixture and most enchanting lighting effects can be provided by giving one or more of the reflectors whose outer surfaces are illuminated a shape or configuration corresponding to that of the supplemental reflector B of the fixture here illustrated and described, to-wit, a shape or configuration which includes an upwardly and outwardly flaring lower portion, an

outwardly and slightly downwardly flaring intermediate portion and an upwardly and outwardly flaring ring-like top portion. Due to the lack of an-upward curvature or disposition of said'intermediate portion, the outer surface of the ring-like top portion of said reflector is not illuminated, with the result that a very pleasing and striking contrast is provided between the top portion of said reflector and the intermediate and lower portions thereof.

Afurther object of the present invention is the provision of an improved ceiling lighting fixture of the indirect lighting type, said fixture being provided at its lower end with an ornamental glass ball or the like, which ball is more or less illuminated, and in a colored manner if a colored disc is used. The provision of such an illuminated ball not only enhances the attractiveness of the present lighting fixture but it also provides a means for illuminating the outer surface of the adjacent supplemental reflector, and if said illumination is of colored character, as itusuallyv will be, unusually beautiful lighting effects are obtained.

Further objects and features of the present invention are in part obvious and in part will appear more in detail hereinafter.

The invention will be readily understood from the following description and the accompanying illustration Mom of the many possible embodiments in which the present invention may take form, it being understood that said description and said illustration are merely illustrative of the invention and do not limit the same.

' In the accompanying drawings, Fig. 1 is a vertical sectional view of a lighting fixture illustrating one embodiment of the present invention; and Figs. 2 and 3 are cross-sectional views thereof on the lines 2-2, and 3-3, Fig. '1, respectively.

In the embodiment of the invention here illustrated, a" canopy 1 is suitably secured to the ceiling 2 and to said canopy is suitably connected the upper end ofv a depending chain 3, said chain carrying at its lower end a generally cylindrical housing 4 for a suitable lamp socket (not shown) in which is removably secured a suitable lamp bulb 5.

Suitably supported from the socket housing 4 is the main reflector A of the present improved lighting fixture, said reflector being of any suitable opaque material, such as spun brass, and of any desired shape. As here shown, it is of inverted, outwardly flaring, somewhat frustoconical shape, with an upwardly and outwardly flaring side wall 10 provided at its upper end with an upwardly extending, relatively narrow' top portion 11 terminating in a short, inwardly extending annular flange 12.

sired shape.

The means for supporting said main reflector from the socket housing 4 comprises a plurality, say three, of circumferentially spaced chains 15 having their upper ends suitably secured to the lower end of the socket housing 4 and having their lower ends hooked or otherwise removably secured to the; upper ends of the vertically disposed portions 16 of generally L-shaped supporting members, the horizontally disposed portions 1'7 of which members extend outwardly through suitable slots 18 in the lower end of said main reflector, said reflector lower end 13/- ing at substantially the junction of the vertically and horizontally disposed portions 1 6, 17oi s aid supporting members, as shown, To, prevent said supporting members from moving inwardly relative to said main reflector, the vertically disposed portions 16 of said members are bolted at 19 or otherwise suitably secured to said reflector.

Suitably supported on the outer ends of the horizontally disposed portions 17, of said supporting members is the upper end portion of a supplemental reflector B, which reflector like the main reflector A may be of any suitable opaque material, such as spun brass, and of any desired shape. As here shown, said, supplemental reflector is of inverted, outwardly flaring, somewhat frusto-conical shape with a lower portion 20 flared upwardly and "outwardly, an;intermediate portion 21 flared outwardlyuand slightly downwardly, and agenerally ring-like top portion 22 flared upwardly and outwardly and terminating in a short, inwardly extending annular flange 23 which rests upon the outer ends of the horizontally disposed portions 1'7 of the L- shaped supporting members. In this way, both the main reflector A andjthesupplementalreflec'tor B are carried by'said L-shaped supporting members, all as will be readily understood.

The function of the main reflector A is, of course, to provide ,the main illumination 'by directing upwardly toward the ceiling the. light rays horizontally emitted by the lamp bulb 5, one such ray being "indicated by the dash-dot line W, and the function of the supplemental reflectorB is to direct upwardly onto the outer surface of said main reflector some'of the light rays downwardly emitted by the lamp bulb 5, one such ray being indicated "by the dash-dot line X. .In this Way, the outer surface of said main reflector is illuminated, said reflector appearing to be of translucent, rather than opaque, material. The light 'raysUWhich illuminate the outer surface of the main reflector pass, of course, from theinner reflecting surface of thesupplemental reflector B upwardly through the circumferentially disposed elongatedspaces 30 between the horizontally disposed'portions 17 of the1L-shaped supporting members and between the-lower end of said main reflector A and the inwardly extending annular flange 23 of the top portion 22 of said supplemental reflector B.

In the embodiment of the invention here shown, an additional supplemental reflector, marked C, is used, the function of which is to illuminate theouter surface of the supplemental reflector B. Like said supplemental reflector B, the supplemental reflector C may be of any suitable material, such'as spun brass, and of any de- It is here shown as of inverted, somewhat frusto-conical shape, with a lower portion 35 flared upwardly and'outwardly and an upper, slightly curved portion 36 extending upwardly and outwardly, and terminating in a reversely bent or depending flange 37.

This supplemental reflector C is supported from the supplemental reflector B located thereabove, the supporting means here shown for said purpose comprising a plurality, say three, of circumferentially spaced, generally L-shaped members, each having a relatively short, vertically disposed securing portion 39 bolted, welded or otherwise suitably secured to the inner surface of the lower end of the supplemental reflector B and an outwardly extending, horizontally disposed supporting portion 40 on the outer end of which rests the reversely bent or depending flange 37 of the supplemental reflector C.

The particular means here shown for supporting the main reflector A and the supplemental reflectors B and C, as well as the means for supporting the ornamental glass ball 50 hereinafter described, form at least part of the subject matter of our copending application for a Lighting fixture, application Ser. No. 653,678, filed January As indicated by the dot-dashline Y, some of the lightrays downwardly emitted by the lamp bulb 5 are directed by the inner reflecting surface of the supplemental reflector C upwardly onto the outer surface, or the suplernental reflector B, with the result that said reflector surface is illuminated and said reflector is thereby caused to appear to spaces 45 between the horizontally disposed port ions 40 of the suppgrting membersfor'saidsupplemental reflectorC and between the lower end of said supplemental reflector B and the depending 'or -reversely bent itop flange'ii l of the supplemental reflector C. Duet'o the lack of an upward curvature or disposition of the intermediate portion 21 of the supplemental reflecto'rB, the outer surface of the ring-like topportion 22 of said supplemental reflector B '-is not illuminated, with the result'that a particularly pleasing and striking contrast is provided between said top portion 22 and the intermediate and lower portions 2 1, 20 cf said supplemental reflector, "all as will be readilyunderstood.

In the embodiment of the-inventionhere illus trated, an ornamental gla-ss ball 50 or the like closes the opening 51 at the lowerend of the supplemental reflector C, said ball being'p'rovided with a suitable stud portion 52 extending upand tojsaild bracketis adjustably securea'such as by means ot'a screw "54, a correspondingly shaped bracket 55 having its lower ends suitably I secured to the'stud-portion 52 of saidball, such as by means of-a split-rivet 56 orthelike. By merely adjusting"said-screw54, the ball 50 can'be drawn r upwardly into more orless rigid assembly with the supplemental reflector '0, thereby avoiding the liability'of said ball 'sha'king or 'rattlingyetc. i

When the lamp bulb "5 is-illuminated, some of the light raysdownwa'rdly emitted thereby, such as the one indicated by'the clash dot'line z, will pass downwardly through the opening 51 at the lower of the supplemental'reflector C and'will hence illuminate'the ball "ta-causing -it tofp'alrticularly glow in a very attractive manner at the of light rays pass before striking said reflecting top thereof adjacent its stud portion 52. In addition to illuminating said ball, some of the light rays passingdownwardly through the opening illuminated parts appear to be of some beautiful. of plain opaquev translucent material, rather than material, such as brass.

In order to give the illuminated outer surfaces of these three reflectors A, Band C a colored.

effect, and hence increase or enhance the attractiveness of the present lighting fixture, suitable. colored means is so positioned below the'lamp bulb 5 that the light rays downwardlyemitted thereby will be forced to pass through said colored means and hence will be correspondingly colored thereby. By providing a set of such means, each of a different color, the illuminated outer surfaces of the main and supplemental reflectors can be given any desired colored effect, and with each change of colored means, a different lighting fixture is seemingly provided, all without sacrificing the main illumination afforded by the fixture or of coloring it in any Way.

' Each colored means as here shown comprises a simple glass disc 60 preferably supported by the main reflector A in any suitable manner. To this end, said main reflector is provided at its lower end with an inwardly extending annular flange 62, on which the marginal portion of a colored glass disc 60 is removably supported. By merely changing colored discs 60, various color effects can be easily, quickly and economically obtained, it being merely necessary to remove the particular disc being supported on the main reflector flange 62 and to position thereon a differently colored disc, all as will be readily understood. In order that the colored effects will be .uniform, each of the discs 60 is preferably of such size as to completely close the lower end or mouth of the main reflector A, thereby making it necessary for all downwardly emitted light rays to pass through a disc, all as clearly shown in .Figs. 1 and 2 and as will be readily understood.

To enable the present lighting fixture to be readily tilted with respect to the lamp bulb 5, to thereby enable one of the chains 15 to be disconnected from the vertically disposed portion 16 of a supporting member and thus enable a change in colored discs to be readily effected, each of said colored discs is preferably of concave form, as shown. As a result, the present fixture can be readily tilted relative to the lamp bulb 5 with- -.out the liability of said bulb and such a colored disc 60 coming into harmful contact.

Further features of the present lighting fixture will be apparent, of course, to those skilled in the art to which it relates.

1. In a lighting fixture, a light source, an opaque main reflector for directing outwardly from said light source a major portion of the light rays emitted thereby, an opaque supplemental reflector having a reflecting area for directing onto the outer surface of said main reflector a minor portion of the light rays emitted by said light source, and colored means spaced from said reflecting area of said supplemental nreflector and through which said minor portion said main reflector a small portion of the light rays emitted by said light source, and colored means removably mounted on said main reflector and through which said small portion of light rays pass before striking said supplemental reflector, whereby the light rays directed onto 'the\ outer surface of said main reflector by said supplemental reflector are correspondingly colored.
