EDEVEEGE FOR ORNAMENTING SHADES REFLECTORS.

Appli-cation med Nevember a, ,19.17.

To all eli/omit may concern:

Beit knownthat I, ALFRED S. POWELL, a citizen of the United States, residing at New York, in the county of Kings and 4State of New York, have invented ,certain new anduseful Improvements in Devices for Or- Shades lor Reflectors, ,of .which the following is a full, clear, and exact description.

In recent years the art of .semi-indirect v,lighting has been Greatly ,extended `and is now in wide use. ``n many places, however, such as residences, the method has made less progress. 'llhis is dueto several causes. For instance, in residences l,where the old direct system is already in use theexpense of the change militatesagainst the adoption of the newer method, but there are coming on the market various. semifindirect `lighting devices of low cos so that the factor of ex pense is now less important. However, the inexpensive devices available for the purpose suffer from a lack of ornamental character and are for that reason barred from many homes, oihces, halls, and other places where their plainness, not to speak of actual ugliness, would be out of harmony with the other furnishings of the apartment.

The inexpensive devices to which I have referred usually include a flat shade or re- Hector such as is commonly used with cluster lights at the ceiling, and this flat reflector is in most cases the objectionable part of the installation, because it is simply a iaring plate of opal glass, plain and unornamented. I have therefore been led to devise my present invention, which has for its object to provide a ring of sheet metal which can be ornamented as desired, for secure` ment around the edge of the flat shade as a finish thereto. consists in a split sheet metal ring, capable of expansion and contractionto fit shades of various diameters, the ends of the ring overlapping and provided with means by which they are held snugly together in ad justed position so as to conceal the joint as well as may be.

The preferred embodiment of the invention is illustrated in the annexed drawing, in which- Figure l is a perspective view showing the ring in place on a flat shade or reflector.

To this end the invention f IPatentedJan.. [29, 19118,. Serial No. 200,210. A

Itheflat shade or reflector. The ring 11 is in the form of an annulus which in the present instance is cylindrical in shape. It is made Iof .astrip of spring sheet-metal, preferably zbrass, or steel plated withbrass, bent to circular form with its ends overlapping as shown. At the lower edge the ring or band `has a circumferential recess l2 toiit over the edge of the shade l0 so as to hold the band on the shade with all necessary securit f andrthereby prevent tipping of the band.

Means are provided to prevent unintended expansion ofthe ring, and also to hold the outer end closely against the other, thereby more effectually concealing the joint. F or .these purposes inthe present instance lI pro .yidethe upper and `lower edge-portions of the ring with a series of small hollow rounded projections,V as 13made by pressing the forming recesses on the inside of the band, so that when the ends are overlapped the projections on the inside end will fit into the recesses on the outside end, as will be readily understood; and I also provide, in the present instance, a keeper 14- in the form of a strap of metal soldered or otherwise attached to the upper and lower edge of the outside end at the extremity thereof. This strap serves to hold the ends against radial expansion and thereby keeps the aforesaid projections and recesses in engagement, which latter effectually prevent circumferential expansion. The result is that the band is held securely in place with the circumferential groove or recess l2 ,firmly embracing the edge of the shade, but by using a little force the inner end can be pushed or pulled in the keeper, thus contracting or expanding the ring to permit removal or replacement or to fit it to shades of different sizes. In general, a single keeper, carried by the outer end and embracing the inner end, is sufficient for the purpose, since radial displacement of the inner end in the inward direction is effectively prevented by the shade itself.

In the construction shown, in which the recesses and projections 13 are provided, the increase or decrease in size caused by expanding or contracting the ring will be found gradual enough for all practical pur-- poses, especially if the projections are small and close together. In some cases the projections and indentations can be dispensed with, especially when the ring is made of thin metal, and reliance placed wholly upon Cir by embossing, etching, enameling, etc., and

when in use provides a clinish which greatly improves the appearance and entirely eliminates the unsightly plainness of the reflector.

It is to be understood that the invention is not limited to the embodiment herein specifically illustrated but can be embodied in other forms Without departure from its spirit.

y 1 I claim:

l. A device for ornamenting a flat shade or reflector, comprising a contractible and expansible split ring of sheet metal provided with means for engaging the edge of the shade or reflector the ends of the ring being over-lapped and provided with coperating means to prevent expansion, whereby the ring can be adjusted to lit the reiector and the joint at the ends of the ring is rendered unnoticeable.

2. A device for ornainenting a flat .shade or reflector, comprising a contractible and expansible split ring of resilient sheet metal. provided with means for engaging the edge of the reflector, the ends of the ring being overlapped and provided with coperatng projections and recesses and one of the ends having a keeper embracing the other, whereby when the ring is fitted to the reflector displacement of the ring and of its ends in any direction is prevented.

3. A device for ornamenting a fiat shade or reflector, comprising the ring described in claim Q, in which the keeper is carried by the extremity of the outer end of the ring and embraces the inner end.

In testimony whereof I hereunto aix my signature.

ALFRED S. POWELL.
