IMPOVEMENT lN REFLECTlNG CHANDELIERS.

Specification forming part of Letters Patent No. 124,582, dated March 1'2, 1872.

To all whom it may concer-n:

Be it. known that I, CHARLES F. J ACOBSEN,

.of New York, in the eounty of New York and Ny invention has relation to reflectir g cha-ir deliers for use in public or private buildings;

and it consists, first, in the hereinafterdescribed construction and novel arran gement of the reflector, which s composed of three or more sections, having the form of truncated polygonal pyramids or cones of different sizes, and placed concentrically one within the other, according to their dimensions. The object of this part of my in ventiou is to produce a large extent of reflecting surface within a limited compass, and to so constitute said refiecting surface that the rays of light shall be reflect-ed outwardly, as Well as inwardly and downwardly, to as great a distance and with as much power as may be required. The second part of my invention con sists in so eonstructin g and arran gingtheforin orframc which encompasses the refiector that its ornamented exterior surface shall be full y illumin ated by mea-ns of the lights below it and be displayed to the best advantage. The third part of my invention consists in the arrangement of burners in their relation to the sections of'the reflector and to the exterior surface of the encompassing frame, as hereinafter described.

In the accompan'ying drawing, illustrating this invention, A represents t-he main tube of the chandelier, through which gas is supplied to the depending burners, and which sustains the various parts of the chandelier. B represents a circular tube surrounding the tube A near its lower end, and attached to it by means of radiatiug pipes b. The tube B is supplied with burners, and, being flanged, has suspended from ita number of glass pendants, b. E represents a second circular tube, constructed and arranged in the same manner as the tube B, but is of greater diameter than the latter, and is placed some distance above it. The radiating pipes 13 supporting the ring 13 are provided with burners so that light may be thrown directly on the innermost reflector. A third circular tube, which should be of less diameter than the tubes B B and be placed above them, may be used to light the reflectol corresponding to it. The burner-tubes B B being of different diameters, the flames and upward Currents of air will not nterfere With each other. These tubes are adapted in size and arrangement to the positions of the sections of the reflector, hereinafter describethso that the light may be thrown fully, clearly, and directly upon the reflectin g surt'aces. O 0 0 designate the different refiectors or sections of the compound refiector. These sections are of the form of truncated polygonal pyramids or cones, their refieeting surfaces made of glass coated with the proper material. The'glass may be either plane, fluted, or otheravise. The inner and outer refiectors O O, being arranged as upright pyramids, face inwardly and downwardly. The intermediate reflector is arranged as an inverted pyramid, and hence faces outwardly and downwardly. It will be seen that, by this arrangement of the reflecting surfaces, the reflected light is more Widely diffused. The frame or base, to which the reflectors C 0 are attached, may be cast in one piece. Between the upper edges of the reflectors G 0 and of the refiector (3 and the tube A, spaces D are left for the passage of the currents of air rarefied by the heat of the flame. The reflectors O C are supported by the pipes c c of a spider, which radiates from the tube A. The reflector O is attached to the form or frame surrounding it, which is suspended by chains c The precise arrangement for support of the refiectors and encompassing form is not material in this invention. The lower part of the reflector O is provided with a flange similar to flanges on the tubes B B On these flan ges a prismatic net-work, gracefully han gin g, is suspended, or, instead of said net-work, glass pendants may be used. The object of the prismatic net-work or pendants is to increase the brilliancy of the efect and to soften and diffuse the light. When the chandelier is used in parlors or apartments Where a somber light is desirable, clouded glass may be used for the prismatie net-Work or pendants. E represents a, fra-me or form encom mssing the refiectors. This form mey be made of Wood, glass, metal, or any other materia-l or combination of materials-opaque or transparent. The shape of this form may be either circular or-polygonal, with its surfece eonczwe and facin g downwardly and outwardly. An inverted frustum of a cone approXimates the nature of the form. The concave surf-ace of said form is highly ornamented by means of molding, pictures, 85o., upon which the light from the burners falls and therefore displays to full View.

The form or rin g surrounding the reflectors has heretofore been constructed and arranged as an uprighttruneated cone or pyramid consequently, its ornamentation could be only imperfectlyobserved, if seeu at all. Another objeetion to the old-style form is the liability of dust to accumulate and eloud the picturesque designs upon its face.

The present invention is free from both these objeetions, and is besides more graceful in its arrangement. The surfaee of the form may to advantage be provided With glass paneis, to 'be used as refiectors of the light oi' surronnding' burners.

The spider-tubos c c are bent down outside the refieetor C, and thenee extend outwardly through suitable opening's in the form, and are provided With bnrners, and, it' neeessary, With globes. These burners serve to give'additional brillianey to the snrface of the form, as Well as to light up the eeiling so as to display the freseoes. Branch tubes 0 may be extended 'out above the form When desired for the purpose oi' illuminating' the eiling. On the outer sur'aee of the refieetor O I place silvered glass, eiiher plain or fluted, and 'thus provide a refleetor which will reflect the rays from the burners 0 of the spider-tubos c to the ceilin I sometimes make the inner surface of the form E a refieetor for thesame purpose.

I have mentioned that the form E may be either opaque, transparent, or semi-transparent.. The object in making the form transparent or seini-transparent is to letthe light from the spider-tubes e* be refleoted by the outer refiecting surfa-ce of the section O through it so that the pictures or designs upon the form may be Well illuminated. When the form is made of Wood or other opaque material, I purpose providing it with transparent or semi-transparent paneis G, ornamented aeeording to taste.

W'ha-t I elaim as my invention, and desire to secure by Letters Patent, is

1. The form or frame llmade of transparent or semi-tran sparent material, or of opaque material with transparent or semi-transparent paneis, in combination With the burners 0 so *disposed as to transmit ra-ys of light through the transparent or semi-transparent paneis, as and for the purpose specified.

2. The refieetor G, in combination With the transparent, semi-transparent, or gl ass-pan eled form E, and the burners 0 snbstantially as specified.

3. In a reflecting ohandelier, the refleetors O C (3 constructed and relatively arranged in the manner and for the purpose specified.

4. In a refleetin g chandelier, the ornainented form or frame E eneompassing one or more refieetors, and upwardly and outwardly fiaring so that the lights from below may be casron its exterior snrl'aee, as and i'or the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presenee of two wituesses.
