ILLUMINATING APPARATUS.

Specification of Lettersiatent.

Patented Oct. 12, 1915.

Application Bled April 22, 1913. Serial llo.l'62,84l.

To all whom it may concern: i

citizen of the United States, residing at Conneaut, county of AshtabulmState of Ohio, have invented certain new and useful Improvements in Illuminating Apparatus, of which the following is a specification.

My invention relates to illuminating apparatus, and especially to apparatus of the bowl illuminator type employed for indirect and semi-indirect lighting.

The object of my invention is to improve and enhance the esthetic effect of such apparatus, as well as its illuminative eiciency and more practical qualities. By my invention, also, the manufacture of such appara- Itus can be greatly facilitated and cheapened, and in the event of breakage or damage it becomes possible to execute repairs at small cost, whereas previously such repairs were either quite impossible or excessively expensive. Various other advantages obtainable in connection with the invention will also become apparent from the following departicular embodiment. It is invention' extends to the particular `form of apparatus described and to many of its specific features and details, which are of importance on account of its specific advantages, yet the invention is not limited to this apparatus and its details, but can be In the accompanying drawing, Figure 1 is a side elevation of the apparatus, a portion being broken away in order that certain structural features Vmay be visible, and Fig. 2 is a partial plan view.

It will be seen that the apparatus shown comprises a bowl structure which is adapted to be suitably mounted or suspended and to contain one or more sources of light ,(as, for examp a number of incandescent lamps), and is intended to throw a portion of the light upward to the ceiling of the room inv which it is used so that the light may be re- Heated downward in such a manner as to give a more or less uniform and Vdiffuse illumin-ation. lVhen illluminators of this type are constructed according to the present ordinar practice and are made of opaque materia s, they present an appearance o dullness which is more or less unsightlyespecially if they are dark in color,-and when they are of large size they are in any case diilicult and costly to manufacture, t1an sport, and install. In connection with my invention, however, both of these objections may be successively obviated,-the first, by a construction and arrangement such that a portion of the light may pass out and illuminate the exterior surface of the bowl without shining directly in the eyesof persons in the room, and the second by making =the illuminator in parts or sec tions suitably arranged and secured.

As shown, the objects above set forth are accomplished by the employment of a number of sections l, 2, 3 and l arranged one section l which closes it at the bottom has itself the form of a relatively small bowl. The several sections l, 2, 3 and l are supported and secured together in proper relative position by means of an interior supporting structure.-which. as shown, also serves for the mounting of a number of the incandescent lamps G and for the attachment of the means whereby the illumiuator is supported. The interior supporting structure shown, it will be seen. comprises a framework made up of annular metallic members or rings T, 8 aud 9, joined together by radially extending members or braces 10. The members 10 are composed of flat strips or bars curved in conformity with the general form of the illuminator and bent at suitable intervals to receive the rings. As -shownJ each of the members 10 comprises two such strips one of which lies beneath the rings and the other of which lies above the rings, and screws or screw bolts 11 serve to clamp the rings between the parts of each member 10.

`about the ring members.

sections 1, 2, 3 andel are supported by being secured to the annular members 7, 8 and 9 near their upper and lower edges, the arrangement being such that the members i', 8 and 9 fall near the overlapping edges of the adjacent sections.

In addition to the framework, the interior supporting structure shown comprises a number of double footed approximately U shaped clips, brackets, o1' hangers 12 which serve as securing means for the attachment of the bowl sections to the rings T, S, and 9. The hangers 12 shown consist of suitably bent` strips of metal, and they are sprung open and slipped over the ring members 7, 8 and i) so that the latter rest in their bends. If it be deemed advisable, screw bolts 13 may be used as shown to secure and clamp some or all of the hanger clips 1'2 on the ring members.

For directly securing the bowl sections to the hangers fasteners 1l more or less similar to the ordinarj. binders of the cotter-pin type that are used for fastening papers together are elnployed. The fasteners 14 may be inserted through holes in the bowl sections and in the feet of the hangers 12 and their ends bent apart in the ordinary manner, washers 15 being preferably used between the heads of the fasteners 11 and the surface of the sections, and also. if deelned advisable. under the bent over ends of the fasteners. VIn the arrangement shown` the outer ends of the fasteners 11 at the lower edge of each bowl section are concealed by the upper edge of the bowl section beneath. As for any fastener ends that are not so concealed (as shown, the heads of these near the upper edges of the several bowl sections), they and their washers 15 may be silvered, for example, ard made a feature of the exterior ornamentation: ror they may be colored to harmonize with 'the surrounding area: or they may even be embedded in the material of the sections themselves or otherwise covered up so as to be invisible. As shown, the heads of these fasteners lie at the center of bosses 1U which form part of the ornamentation of the bowl, and so are not prominent at all.-

The lamps G and their shades are, it will be Seen, mounted in holders or sockets 17 of any desired or approved form, and the sockets 17 which are carried from the framework 5 are fastened to brackets 1S which are clamped on the ring members 7, 8 and 9. As shown, the brackets 1S have forked ends which fit over certain of the hangers, the screw bolts 13 used with these hangers passing through holes in the sides of the forks as well as of the hangers, so that the brackets 18 are eflectually prevented from turning An additional lamp 19 is arranged at the bottom of the lowermost bowl section 1 in a socket 2() suitably secured there. The suspension means or chains 21 which in the apparatus shown support the illuminator are secured to split collars 22 clamped on the upper ring i) by suitable screws.

While the sections 1, 2, 3 and l can be ,made of any desired material and of any de .sired size, it will be understood that the greatest advantages of my invention arise Yin the case of bowl Ailluminators of quite large size (e. y. some three or 'four feet or more in diameter) suchas are usually made of a plaster composition known as compo." Xot only do such illuminators benefit greatly in appearance by the more or less direct illumination of their exterior surface which such a construction as that above set forth affords, but b v being made in sections they become very much easier and cheaper to manufacture, transport, install and repair. In the first place, the individual sections are lighter and less bulky, especially as the largest annular portions need not necessarily be in a single piece. In the second place, the sections may be so designed that illmninators of Iany size that will in practice be required can be made up with the same line of smaller sections, so'that it is possible to make the smaller sections on a comparatively large scal pind in the most economical manner, while tl e manufacture of the "ery largest sections for which the demand is small can be handled as more or less of a special matter just as the making of specially large bowls of the present ordinary construction would be handled. As regards repairs, moreover, it will often be possible to make them with a minimum of expense and a maximum of promptitude by simply replacing a damaged or broken section with a new one,-besides which the sectionalized construction in itself tends to localize and minimize any injury that the illuminator may sustain.

'hat I claim as new and desire to secure by' Letters Patent of the United States, is

1. An illuminating apparatus comprising an inner' ring, means for supporting said ring, and an annular inclosure disposed outside of said ring and supported thereby, said support being arranged to allow the ready removal of, said inclosure.

2. An illuminating apparatus comprising a plurality of superposed rings joined together. means attached to the uppermost of said rings-for supporting the said rings from above'. a` pluralitv of superposed inclosure sections surrounding said rings, and meanslfor allowing the ready removal nf anv one of the said inclosure sections.

3. An illmnimlting apparatus comprising a plurality of superposed rings joined together, a plurality of superposedinclosure sections surrounding the said rings and supported thereby, and a light source supported sections surrounding the said ring and having their adjacent ends supported by said ring.
