UNITED STATES PATENT oF icE 1v. Y., A CORPORATION or new Yonx LIGHTING I Application filed June 19, While particularly applicable to floor lamps and torcheres, the broader principles of my present invention are useful in other relations.

It is among the objects of the invention to provide a fixture of few parts, simple andinexpensive construction, whichumay be assembled with the utmost facility to afford a highly ornamental appearance.

-without the need for supporting framework that would necessitate special concealing'instrumentalities.

Another object is to provide a fixture of the above type, the assemblyof which.requires no clamping rings or screws and no delicate adjustment, but in which the constituent parts need merely be placed in posi:

tion and are'thereby supported in secure and properly centered relation. v

Another object is to. provide a lighting fix- A ture of the above type, in which the use of corona effect.

i but a single incandescent bulb, striking composite illumination effects are produced at the lamp shade, which effects may include or namentally spaced translucent area's shining by transmitted light and intervening relatively darker areas which may, however, be much more faintly illuminated by reflected or diffused light, the bulk of the illumination being, however, projected for maximum illuminating effect.

More specifically it'is an object to afford an indirect lighting fixture in which the major portion of the illumination is cast upon the ceilin instead of being transmitted through e translucent shade, said shade however being directly exposed for transmission of light therethrough at ornamentall disposed windows and preferably also at the outer rim of the shade for a brilliant A feature of the invention is the use of a translucent ornamental shade encircling a '33 of Fig. 2.

light reflector means therein which inter-l cepts the light otherwise transmitted through the shade, and casts the light against theceiling or otherwise, the conformation of the revflector relative to the shade being such,',however, as to expose portions of the shade for transmission of light therethrough to afford ornamental effects. Another feature is the mechanical coordination of the shade, the reflector and the 1 lamp. Preferably the standard, pedestal or other support is provided with an ornamental socket in which is sustained the reduced bell shaped hub of the shade. E

In a preferred embodiment, the, brilliant, corona effect is produced by the protrusion of the shade rim beyond the rim of the reflector.

Preferably the shank of the electric lamp bulb extends through axial apertures in the .20

reflector and in the shade and is threaded into a lamp socket inthe standard. The shade sup ort socket in a preferred embodiment is per orated to afford an open work latticed, or lantern effect for direct transmission of Fig. 1 is aside elevation of an'indirect .130 lighting floor lamp formed in I accordance with the present invention.

using various illumination sources and various shading and reflecting means.

In that form of the invention here shown the lamp includes a pedestal including a supporting base 10 and a vertical rod 11, of any desired artistic design.

Mounted as by screw threading or the like upon the upper end of the stand 11, a supporting and enclosing ornamental housing 12 is provided within which is mounted the lamp socket 13, which is preferably of the pull chain switch socket type and which receives an illumination source such as the partially frosted incandescent lamp bulb 14.

' The upper end of the housing 12 is flared outwardly and the side walls are apertured, thus to provide an apertured cup shaped socket as shown in Fig. 5. The configuration of the socket is such as to provide an outer ring 15 joined to the body of the housing 12 by spider like connecting struts 16 which form therebetween ornamental windows 17.

Supported by the socket there is provided a translucent light diffusing shade 18, which is preferably substantially bell shaped, and may have a substantially upstanding rim flange 19. The base or hub of the shade is of reduced bell shaped configuration as at 20, and is received within and embraced by the socket, whereby the interfitting of the shade within the socket constitutes a sufiicient and complete support therefor.

The rim 15 of the socket which constitutes the support for the shade is substantially segstituting a support for the shade by receivmg thereon the lower portion thereof just adjacent the hub 20 thereof. The substantially vertical face is also curved to conform with the curved surface of the hub. Thus while the upper surface sustains the weight of the shade, the inner surface embraces the side of the hub to prevent lateral movement of the hub within the socket.

The shade 18 is suitably embellished by decorative work as indicated af'18A, such decoration preferably extends outwardly from the surface of the shade and is received within the windows 17, as shown in Fig. 6 thus insuring proper alignment of shade an support. Turning movement of the shade within the su port is prevented by contact of the decoration withthe struts 16.

For reflecting rays outwardly from the illumination source, there is provided within the shade 18 a reflector 21 which is preferably of silvered metal or equivalent opaque reflecting material. The reflector 21 is also substantially bell shaped but does not include a reduced portion at its inner end. The outer rim of the shade 21 may be reversely bent as of rim 22 against the inner face of the shade below the flange 19 thereof. The reflector is of curvature difl'erent from that of the shade ,to contact the-latter substantially only at rim 22, thereby forming a dead air space between the shade and the reflector to prevent overheating of the shade from the heat generated by the bulb 14. The shade, however, affords complete support for the reflector by suspending the latter from its rim.

The shade has a hub aperture 23, and the reflector an aperture 24, the stem 25 of lamp 14 extends through said apertures and is threaded into the socket 13. The bulb 14 of the lamp is of larger diameter than the apertures 23 and 24 so that the shade and reflector, though they merely rest upon their respective supports, cannot drop out of place if the fixture be moved about or roughly handled.

Thus it will be seen that the assembly prosv vides for the axially aligned support and re- {ention of the housing, shade, reflector and amp.

In the operation of the device when the bulb 11 is energized, light will shine therefrom directly through the inner face of the shade both at the flange 19 and at the windows 17. The major portion of the illumination will be reflected upward from the reflector 21 and cast upon the ceiling. The interposed opaque reflector renders the body of the shade dark, but the protruding rim flange 19 unshielded by reflector 21 appears almost incandescent by contrast,afi'ording a most attractive corona eflect.

The lattice Work or equivalent efi'ect produced by shade hub 20 within the socket struts affords a miniature lantern effect, light from lamp 14 passing through ornamental windows 17 which are bounded by the opaque rim 15 and the struts 16.

The exterior of the shade is faintly illuminated by reflected rather than by transmitted light. This illumination-results more particularly by diffusion from windows 17 and from the corona rim flange 19. Surface ornamentation on the shade will thereby be eifectively set off.

The bulb 14 of the lamp assembly is preferably frosted over the upper portion of its surface as indicated, and diffuses the light that is directly cast upon the ceiling and prevents a sharp image of the incandescent filament thereat: The illuminated rim flange 19 moreover aids in shading off the rim of the more or less sharply defined circle of li ht otherwise cast upon the ceiling from re ector 21.

It will also be noted that the frosting extends over only the outer top end of the bulb. and permits direct impin ement of light rays against the flange 19, the ody of-the reflector 21 and'the reduced base 22. Thus the reflector receives a maximum of light from the illuminating source and spreads or difiuses the same over a relatively larger ceiling area.

The invention as herein described will be seen to provide not only simplicity of structure and assembly together with lighting efficiency, but will moreover provide novel lighting effects which are not dependent upon super structures or added parts of any kind. The lantern eflect at'the base of the shade will be seen to be provided without the use of either separate light sources or additional parts or complicated structures. The corona the source and supply energv or fuel thereto will be utilized without departing from the spirit of the invention.

It will also'be understood that, if desired,

I the reflector may be joined'permanently to the" shade or may be formed as an integral part thereof, asby application upon the shade of reflecting material by electroplating or the like. The invention is of course not confined to the use in a single device of both the windows and the corona flange, each one bein separately applicable in a lamp assemb y. r

It will thus be seen that there is herein described an apparatus in which the several features of this invention are embodied, and which apparatus in its action attains the variousobjects of the invention and is well suited to meet the requirements of practical use.

As many changes could be made in the above construction, widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all mat- .ter'contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
