" LIGHTING FIXTURE Filed Aug. 13, 1928 2 Sheets-Sheet 2 Patented Oct. 7, 1930 PATENT OFFICE" PAUL M. noronxm, OF'GHIGAGO, 'IIiLINOIS LIGHTING FIXTURE Application filed August 13, 1928. ,Serial 170,299,237.

My invention relates to illuminating appliances and has more particular reference to a lighting fixture-in which the. principles 7 r of indirect illumination are employed. a e 5 In the present construction I have utilized a chandelier-body of annular or ringlike formation that is open at the top and bottom and is provided with means to support a translucent glass bowl in the open 10 bottom portion and a transparent or sen1itransparent cover or closure for the open top portion. Within the chandeliermember I have positioned a reflector to direct the light rays upwardly and outwardly through the cover and in the bottom of the reflector there is an openingin which the light diffuser is placed. lVith the above briefly described construction. the greatest volume of light-rays emanating from the lamp are re- 2 flected upwardly against the ceiling or other plane surface above the fixture, and the por:

tion ofthe rays which reach the diffuser pass through the same and illuminate the lower bowl. The cover is secured to a socket element in which the bulb is placed and the chandelier is supported from the top of the structure. In a device made in this manner the reflector is maintained in a clean condition because dust and other matter is ex cluded from it and by forming the annular chandelier member in two parts in hinged relation to each other the bowl carrying portion may be released and swung downwardly for-inspection of the interior or for replace' ment of any of the p'artsor for wiping the reflector. ,This may be done'without having to take the fixture apart. e e

In devising this lighting fixture I have numerous objects in mind, among which are dependability and readiness of operation,

durability in construction, simplicity and,

sturdiness in the formation and arrangement of the parts, accessibility for the purpose of adjustment, replacement or cleaning and the entirefiXture is arranged, fabricated and assembled. in a novel and. economical manner which permits it to be retailed for a reasonable price. 7 he i .I prefer to carry out my invention, and to accomplish the numerous objects thereof drical tormation, and upper. part of. the chandelier-body is ofL-shape in cross sec-*" in substantially the manner hereinafter fully described and as more particularly pointed out in the claims, reference being herein made to the accompanying drawings that form part of this specification. 7 e a In the drawings Fig. 1 is a vertical side elevation of a lighting fixture made in accordance with my lnvention with a portion broken away "and section to disclose the interior construcion.

' Fig. 2 is a vertical axial section of the fixture shown in Fig. 1. i

Fig.6 is a view, in perspective, of a'portion of the chandelier-body showing the details of a bracket or mounting for the reflector element. p r r a Fig. at is a fragmentary detail of the manner of securing the'cover and chandelierbody together, the view being taken on line 44.- of Fig. 1 and looking in direction of tl1earrows.""-'- The drawings are to be understood as schematic for the purpose ofillustr'ating a typical or preferred forrnin which my invention may. be made and in these drawings the samereference characters have been employed to designate like parts wherever they appear throughout the several views.

The construction which I have disclosed comprises a chandelier-body A that is open at its top and bottom, which openings are closed by a cover and a bowl, and these parts are thus cooperatively related and assembled with the body so as to: enclose a reflecting device. The chandelier-body is of annularshape, and consists of two pieces of suitably shaped sheet-metal interfitted and in hinged relation to each other. The lower, part 5 of the ehandelierebody, is of a compound curved shape in the cross-section with its lower edge formed into an inwardly extending flange (landwith its upperportion formed into an upstanding rim 7 of cylintion the longer 1ne1nberf8 being of cylindrical shape so asto interfit with the rim 7 of the lower part and the shorter lateral member 9 of the upper part projects inwardly from the upper edge of the member 8. A hinge 10 connects the members and opposite the hinge the member 8 is provided with a hollow embossment 11 that is threaded to receive the thumb screw 12 that passes through the aperture in the adjacent segment of the upstanding rim 7 so as, to thereby maintain the two parts of the chandelier body in normal position. I r

The upperopen portion ,ofthe chandelier-. body A is closed by a cover 13 made of transparent or semi-transparent glass that is preferably roughened upon the interior surface as indicated at 14 for the purpose ofbreaking up light rays that pass through the cover and avoid undesirable rings or striations upon the ceiling or other surface uponwhich the upwardly directed li ht rays impinge. At its lower edge the cover has a laterally projecting flange or bead '15 that projects under the flange 9 of the chandelier body A and the upper portion of the cover 13 is pro vided with an opening and the edge thereof projects inwardly as at 16 to provide a flange whereby the cover'is connected to the lamp socket or hanger 17 by means of an attaching plate 18 having spring tongues v19 that en gage with the edge of the cover. An ornamental husk or cap 20 encloses the portion of the socket that projects above the cover and a suitable hook 21 thereon provides means whereby the fixture may be suspended from the ceiling or other surface. I

The lower open part 5 of the chandelierbody is closed by a bowl22 preferably made 7 from opal glass or other translucent material,

the bowl being hemispherical in shape and is provided onits upper edge with a lateral outwardly projecting flange or bead 23 that rests upon the lower flange 6 of the chandelier body.

Mountedwithin'the chandelier-body isa reflector 24 that is designed to reflect light rays upwardly and outwardly from within the chandelier-body from a bulb or light unit 25 that is mounted in the socket 17. The reflector is preferably opaque and one of its surfaces is silvered' to increase its reflective property. The lower portion of the reflector 24 is provided with an opening 26 and the walls of the reflector at this portion extend inwardly towards the axis of the reflector. as shown at 27. 7 I

Positioned in opening 26 is a light diffuser 28 in the form of a cup of opal glass or other translucent material that has an outwardly flared lip 29 at its upper edge so that the diffuser may beinserted into the opening 26 and will be supported by engaging the lip withthe inward portion of the reflector. Light rays from bulb or light unit 25 pass through the opening 26 and through 'the difluser 28 and are scattered upon the bowl 22,,cau'sing illumination'thereof, but it will be understood that only a portion of the light rays emanating from the fixture are utilized in illuminating the bowl 22.

The reflector 24 has an outwardly flared upper portion 30 and is supported from the chandelier body by means of several spring arms 31 which at their free ends are provided with concave notches 32 in which the edge of the flared portion 30 of the reflector is seated. These spring arms 31 comprise the upper portions of brackets made from strips of suitable metal and said arms 31 project obliquely inward from straight portions 33 which at their lower ends are provided with lateral tongues 34. The brackets 31 are removably mounted in holders that are secured to the portion 5 of the chandelier-body A, and each holder consists of a strip of metal bent angular shape so that there is an upright portion 35 that rests upon the flange 6 and a horizontal portion 36 that extends outwardly towards the curved portion of the member 5 of the chandelier-body where it is provided with an oblique flange 37 that lies flat against the wall of the portion 5 and is brazed or welded thereto. In order to mount the bracket 31 in the holder the latter is provided with a slot 38 at theangle formed by its

portions

35 and 36 and adjacent the lower edge of the upright portion 35 there is another slot 39 through which the tongue 34 protrudes in a position to be above the rim 23 of the bowl and thus maintain the latter against accidental dis lodgeinent. A lateral recess 40 extends downwardly from the slot 38 to receive tl e shank of a set-screw 41 that is screwed into the straight portion 33 of the bracket to claim the latter in position.

' In order to maintain the cover against rotation and to assist in securing it to the chandelier-body the flange or bead 15 of the cover is provided with a plurality of recesses 42 to receive squared blocks or nuts 43 and small screws 44 are inserted through thewall 8 of the chandelier-body and screwed into the re spective blocks or nuts 43 in these recesses.

Vvith the construction above described the reflector and the light unit are protected against dust and foreign matter, and whenshown in dotted lines in Fig. 2 and will carry with it the bowl, the reflector, and the difluser without disturbing the latter. If it is then desired to clean the reflector and the diffuser the latter may be lifted out and'the former may be releasedfrom the spring brackets 31 and removed with ease. lVhile the reflector and difluser are out of the fixture the bowl 22 may be cleaned without removing it. It is also possible with the herein disclosed con struction to readily replace the lamp or bulb 2 Whenever desired merely by opening the chandelier-body.
