PATENT OFFICE.

SIDNEY M. ISRAEL, or RICHMOND HILL, NEW YORK.

ELECTRIC-LIGHT CI-I.AIWDELIIERv To aZZ whom it may concern: Y Y

Be it known that I, SIDNEY M. ISRAEL, a citizen of the United States, and a resident of Richmond Hill, county of Queens, and State of New York, have invented certain new and useful Improvements in Electric- Light Chandeliers, of which the following is a specification. v

My improvements relate to the type of chandelier for electric lamps well known in the present state of the art, in which a concavo-convex plaque is suspended from a ceiling fixture, and formed with a plurality of equi-distant radially protuberant bracket arms for the support of a corresponding number of pendent lamp holders, shades, etc.

These concavo-conveX plaques for the support of pendent electric lamps are made of opaque material, usually of an alloy, and as the electric lamps are positioned below the plaque and partly under the rim thereof, the imperviousness of the plaque to light rays causes a shadow thereof to be cast upon the ceiling, which fact is objectionable, and detrimental to the sale and use of chandeliers of this type. Furthermore, the dishshape of the plaque, with its concave side uppermost, affords lodgment for an accumulation of dust which cannot be conveniently removed, so that for sanitary and other reasons the plaque chandelier as heretofore constructed and used is not entirely satisfactory.

It is the object of my invention to obviate these difficulties, and to render this type of chandelier more desirable, effective and sanitary in every respect, and this I accomplish by, and my invention consists essentially in, inclosing the upper concave side of the plaque by means of a transparent cover or lid, and in utilizing said concavity as a lamp chamber, so that light emanating therefrom, and through the transparent cover, will illuminate the ceiling above and eliminate the shadow of the plaque.

I thus not only increase the lighting capacity of the chandelier, and effect the diffusion f of light in such manner as to obviate or render innocuous plaque shadow, but I also prevent the accumulation of dust and eX- traneous matter in the concavity thereof, and facilitate the cleaning of the chandelier, from the cover of which the dust maybe readily removed or dissipated by ordinary and well known means, such as a feather duster or equivalent.

Specification of Letters Patent.

Patented Sept. 6, 1921.

Application led August 4, 1920. Serial No. 401,128.

In the accompanying drawings,

Figure l, is al perspective view of an electric light chandelier of the type designated, embodying my improvements;

Fig. 2, is a top view of the plaque, with thelransparent cover broken away in part; Fig. 3, is a sectional elevation taken upon general plane of line 3-3, Fig. 2.

'Ihe usual ceiling fixture or hanger C, is provided with hooks c, c, or equivalent means for copulation with the upper extremities of Suspenders s, s, the lower ends of which are attached to loops p', p, on the rim of plaque P. The latter is of the usual con cavo-convex form, and is provided with the usual radial bracket arms or extensions p', p', for the support of the lamp holders h., and shades 7L', in a manner well known in the art.

The inner portion of the rim of the plaque P, is formed with an annular shoulder p2, or an annular series of shoulders, or equivalent means for the support of the cover K, the latter being formed in whole or in part of transparent or translucent material 7c, for the passage of light rays emanating from an electric lamp e, positioned in the bottom of the plaque as exemplified in Fig. 3, said incandescent lighting means being placed in electric circuit in a manner well known in the art, and therefore not shown in the drawings.

It is obvious that the cover K, might be made of a single piece or dome of glass or other transparent or translucent medium if so desired; but in the drawings I show it as consisting of four transparent panels 7c, 7c, supported in a suitable metallic frame work 7c', k. Qbviously the specific construction of the light transmitting cover K, is of secondary import, and I do not wish to limit myself in this respect, the essential feature being the use of a cover K, that will inclose and protect the concavity of the plaque I), and exclude therefrom dust and extraneous matter, while allowing the escape of light rays emanating from an. electric source of illumination e, positioned within the plaque P.

The inner concave surface of the plaque I), may be treated or prepared in any appropriate manner to augment its reflective capacity, and in this respect may be likened to a parabolic mirror whereby the interior light rays may be concentrated and defiected upward through the transparent or translucent cover.

By the term light transmitting cover` as used herein, mean to designate a cover that is either in Whole or in part composed of transparent or translucent material.

Vhat I claim as my'nvention and desire to secure by Letters Patent is,

An article of manufacture comprising an electric light chandelier of the character de- Y for said plaque supported by Vsaid shoulder and formed of a light transmitting material, said cover inclosing the concavity of the plaque to constitute alight-receiving chamber', a lamp socket in the bottom ofthe plaque, and means on the rim of the plaque for the attachment of suspending Vmeans for the chandelier.
