GEORGE F. SPENCER, OF NEWARK, NEW JERSEY.

REFLECTOR FOR ART-GALLERIES.

SPECIFICATION forming part of Letters Patent No. 619,849, dated February 21, 1899.

Application iiled July l5, 1898. Serial No. 685,988. (No model.)

To all whom it may concern:

Be it known that I, GEORGE F. SPENCER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Reiiecto rs for Art-Galleries, Show-IVindows, &c. and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this speciication. f

This invention has reference to improvements in reflectors, such as are used more particularly in art-galleries to illuminate the pictures or to light up show-windows in stores to display the goods to their best advantage.

The present invention, therefore, which is in the nature of an improvement upon the construction of reflectors described and claimed in former Letters Patent of the United States numbered 581,093 and dated April 20, 1897, has for its principal objects to provide a reilector Which may be used in connection with electric or other lights and which is provided with a guard or shield to entirely conceal the direct light from the observer.

A further object of this invention is to provide in connection with my novel form of reflector an adjustable bracket and support which may be attached directly to the Wall or may be suspended from the picture-molding or may be secured to the back of the frame of the picture, such bracket and support permitting the adjustment of the reflector horizontally closer to or farther away from the picture and also vertically in front of the pioture, the reflector itself having a rotary n10- tion to enable the proper adjustment of the latter in front of the picture after the adjustment of the bracket and support, and thereby producing the best lighting eect to illuminate the picture and displaying the same to its best advantage.

Other objects of this invention will be evident from the accompanying specification.

My invention therefore consists in the novel construction of re'liector and adjusting mechanism to be used in connection therewith for illuminating pictures in art-galleries and for lighting show-windows, &c., all of which will be fully described in the accompanying speciication and finally embodied in the clauses of the claim.

The invention is clearly illustrated in the accompanying drawings, in which- Figure 1 is a plan or top view of the adjustable reflector and bracket and support embodying the principles of my present invention, and Fig. 2 is a side view of the same. Fig. 3 is a front view of the reflector, illustrating more particularly the arrangement of a guard or shield to conceal the direct light from the eyes of an observer. Fig. 4c is a front view of one form of adjustable bracket and support to be used in connection with the reflector. Fig. 5 is a view, on an enlarged scale, of the inner portions of the reflector, illustrating certain details of the construction in vertical section. Fig. 6 is a longitudinal vertical section, on an enlarged scale, of the adjustable bracket, illustrating also in connection therewith an arrangement of electriclight wires. Fig. 7 is a side view of a portion of the reflector-carrying bracket and its socket for adj ustably attaching the bracket against the back of the frame of a picture. Figs. 8 and 9 are a front and top edge view, respectively, of the socket which is used in connection with the form of bracket represented in said Fig. 7.

Similar letters of reference are employed in all of the above-described views to indicate corresponding parts.

be seen from Fig. 5, are provided with openings a4, over which I have secured in any wellknown manner suitably-ornamented caps c. In the perforated end of each cap is a setscrew c', on the threaded end of which I have screwed a nipple c2, provided with a shoulder c3 and a screw-threaded end c4. Each nipple c2 has one or more openings c5 for the reception of electric-light wires d', which lead IOO through said nipples to incandescent lamps (Z, said lamps heilig screwed directly upon the screw-threaded ends c4 and against the shoulder ci, as clearly indicated in said Fig. 5. The reflector can thus be provided at each end with an incandescent electric light, as shown.

If desired, a bracket-bar b, having a screwnipple b', may be fastened upon the inner surface of said arc-shaped portion d and provided with an incandescent light (Z2. The back or angularly-formed portion of the reflector has an opening a5, through which the wires CZ are passed to be connected with the several lamps oZ and (Z2, as clearly illustrated in said Fig. 5. Against the inner surface of each one of said angularly-arranged portions a2 I have secured by means of prongs f certain silver-plated glass or polished-metal plates f, which are for the purpose of reflecting the light-rays inward and downward. Said fastening devices for securing said plates in position and the arrangement and construction of said plates are preferably such as are set forth in said Letters Patent numbered 581,093 and hereinabove mentioned. Connected directly with the lower edge a6 of the said arcshaped portion a' is a downwardly-extending part a7, which forms a guard or shield, the same being connected with portions of the said side pieces a3, as indicated more particularly in Figs. 2 and 3, and its arrangement being such that at all positions of the rotary adjustment of the reflector it will protect the eyes of the observer from the direct lightrays of the lights within said reflector. The reflector is usually arranged in front of a picture by being suspended from a bracket, preferably of the construction illustrated in said Figs. l to G, inclusive. This form of bracket and support consists, essentially, of a main plate c, which is formed at or near the top with hooks c for arranging it over the usual picture-molding g, (see Fig. 2,) or it may be provided with a perforation e2 for suspending it from a nail. As will be seen from said Figs. l, 2, and G, said plate e is provided with a pair of ornamental posts e3 and e4, which are' provided with perforated ears or lugs e5. Pivotally arranged on a pin e. in the ear or lug of the post e3and embracing the ear or lug of said post are a pair of ears e8 of a short arm e7, which is provided with a socket e9, open both at the top and bottom. Suitably secured in the said socket e9 is the end 7L of a tubular arm 7L. Pivotally arranged on a pin 'i' in the said lug or ear c5 of the upper post c4, as will be seen from Fig. l, and embracing the said lug are a pair of ears Z2 of an ornamental joint or connection fi, the latter being attached to a rod or tube 113, which has a similar joint or connection 4 at its opposite end. Said joint or connection t4 is provided with a pairof perforatedlugs orears 5. Slidably arranged upon an arm 7L and adapted to be secured in any fixed position on said arm by means of a set-screw h2 is a sleeve h3. Said sleeve has an upwardly-projecting lug or ear 7L, which is provided with a hole and is secured by means of a pintle or pin h5 between the said ears Zi", hereinabove mentioned. It will thus be seen that the said arm 7L can be raised or lowered on these hingejoints connected with the plate e and can bc held in its adjusted position by tightening up the screw h2 of the sleeve h3. Telescopically arranged within said arm 71. is another tubular arm or rod h and a sleeve h7 and setscrew he for locking said arms 7L and hf in their adjusted positions in relation with one another. Secured upon the free end h ofthe arm h6, by means of a set-screw 7o or in any other well-known manner, is aball k, which is provided with a chamber k2, having a downwardly-extending opening 7c3 and a pair of oppositely-arranged openings 7a4, in which I have secured in any well-known manner the ends of certain rods Z. The opposite ends Z of said rods Z, as will be seen from Fig. 5, are secured by means ot' set-screws Z3 in certain socketed port-ions Z4 of ornamental posts Z2, which. are secured by means ot' screws Z5 or otherwise upon the upper portion of the refiector-casing. It will be seen that while the arm 7L is adjustable vertically and the arm h can be moved in or out in the arm h to bring the reflector closer to or farther away from the picture said reflector is also rotatably conneeted with said bracket support when the said set-screws Z are properly manipulated.

When the reflector is to be used with electric lights, the wires are passed through the tubular arms 7L and h6, through the opening 7c3 in the ball Zt, and through the hole or opening a5 in the reiiector-casing to be properly connected with the lights, as will be clearly understood from an inspection of the several figures of the drawings.

In lieu of the form of bracket -support illustrated in said Figs. l to 6, inclusive, I may secure against the back of the frame of the picture a socket rm, which is provided with several ring portions 'm' and ,set-screws m2. Secured in said ring portions m', by means of said set-screws m2, is a bracket-rod n, which is tubular and extends over lthe top of the frame of the picture, as indicated in Fig. 7. In this rod I have slidably arranged the arm h, hereinabove mentioned, to which the reiiector A may be secured in the manner previously described. Of course it will be evident that the refiector may be used with ordinary gas-jets or other lighting means, if desired.

I am fully aware that many changes may be made in the several arrangements and combinations of the parts and in the details of theconstruction thereof without departing from the scope of my present invention. Hence I do not limit my invention to the exact arrangements and combinations of the several partsf as herein described, and illustrated in the drawings.

The essential feature of my invention is the IOO IIO
