To all whom cmay'concem:

Be it known that we, HENRY. G'. LANE and HARRY STANFORD WILLIAMS,- citizens of the United States, residing at San Diego, in

p the county of San Diego and State of California, have invented certain new and useful Improvements in Electric Signs; and ywe do declare the following to be a full, clear, andl exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to useful improvements in electric signs and more particularly to those ofthe indirect radiation type employing a plurality of reflectors for intensifyingI ight rays projected from a source o light within a housing, arranged in the face plate of said housing` corresponding with the shapes of a number of characters.

The object of the invention is to provide al sign of this class having im roved means for detachably securing the re ectors thereof in position, such means serving also toretain in position a plurality of transparent lens plates which prevent' dust and the like from entering the casing through the openings therein.

With this general object in view, the invention resides in certain novel features of construction and in unique combinations of parts to be hereinafter fully described land claimed, the descriptive matter being supplemented by the accompanying drawing which constitutes a partof the application and in which Figure 1 is a face view of a sign constructed in accordance with the invention; Fig. 2 is a vertical section thereof as seen along the plane indicated by the line 2-2 of Fig. l; Fig. 3 is a rear elevation of a portion of the face plate and one of the reflectors carried thereby; Fig. 4 is a vertical section taken on the plane designated by the line 4-4 of Fig. 3; Fig. 5 is a view similar to Fig. 3 disclosing the application to use of a supplemental reflector; Fig. 6 is a vertical section of Fig. 5 taken on the plane indicated by the line 6 6. Fig. 7 is a front elevationl of a portion of the sign constructed as disclosed in Figs. 5 and 6.

In these drawings, similar reference characters designate corresponding parts throughout the several views, C designating lights through openings l ELECTRIC SIGN.

broadly an appropriate casing or sign box havlng a face plate P provided with a number of preferably circular openings O so dlsposed as torepresent one or more letters, numerals, or other characters. Disposed within the casing C and preferably adjacent the lower side thereof, is a pair of electric L whose rays are to be reflected through the openin s O to illuminate the sign, the radiation o such rays being facilitated bythe reiiectors l shown in Figs. 1 to 4 inclusive, or by those indicated at la and 1b 1n Figs. 5, 6 and 7. Each reflector l is here shown in theform of. a metal disk having in one of its edges a slot 2 which ,constitutes an eye, while at its opposite edge and preferably p formed integrallytherewith, each reiector -1 is equipped with an arm 3 Whose free end is bent to form a hook 4.

Coacting with the eyes 2, is a plurality of hooks 5 which are here shown as disposed at the upper sides of the openings O and as formed of tongues left projecting into sai'd openings when the same are formed in the face plate. As clearly shown in Figs. 3 and 4, the eyes 2 receive therein the hooks 5 when the reflectors are to be applied to use, while the hooks 44 are received in eyes 6 formed .in rearwardly q extending tongues which are likewise left extending into the openings O when the latter are formed. B-y this manner of attaching the reiectors, it will be evident that although theymay be quickly and easilyy applied, they willbe reliably held in correct position. Furthermore, the attaching meansis so simple as to allow unskilled laborers to correctly position the reflectors with respect to the numer-` closed in Fig. 2 whereby, when applying the reflectors, by simply passing the e es 2 over the hooks 5, and snapping the hoo s 4 in the eyes 6 such reflectors will'be properly positloned at the correct angle to the face plate without making any adjustments whatsoever. In most cases, lit becomes expedient to provide a transparent closure for the several openings O to preventI the entrance of dust and the like, and although such closures might well Vbe in a number of forms, they are preferably embodied as shown 1n the drawings in which is depicted a plurality of transparent plates 7 of circular contour, said plates being constructed of glass, mica, celluloid or any other appropriate transparent material. At diametrically opposite points, the plates 7 are provided with slots 8 in their edge portions receiving therein the hooks 5 and the tongues in which the eyes 6 are formed. By this arrangement, 'whenthe reflectors l1 are properly positioned, the lens plates will be reliably held against dislocation, it being thus evident that although the construction is exceedingly simple, it will be highly efficient.

In Figs. 5, 6 and 7, a pair of hooks 5a and 5b is shown disposed at diametrically opposite points adjacent the edge of the opening O in the plate P, such hooks being passed through eyes 6a and y6b in a frusto-conical reflector la which is preferably corrugated circumferentially, the opening O being closed, in these figures, by an appropriate lens 9 having a circular enlargement 10 which closely abuts the wall of the opening O, and a flange 11 ywhich is interposed between the inner side of the plate P and the reflector la. The rear contracted end of the reector la is provided on one of its sides with a hook 5 and at a diametrically opposite point with an eye 6c the former being` received in an eye 2c on the upper edge of a reflector lb similar to the reflectors 1; pre-- viously described, said reflector `l`l'b having on its. lower edge a laterally extending arm 3 having its terminal bentl to form a hook flreceiv'ed by the eye 6.k The-only difference between the reflectors '1 "and", 1b is that the latter kare preferably provided with parallel corrugations to intensify the light rays reflected therefrom.

The active facesof all ofthe reflectors are to be silver or nickel-plated, and the inner side of the casing C will be preferably painted a light color, theseprovisions being obviously made to increase materially the brilliancy of the rays projected from the rom the foregoing description, taken in connection with the accompanying drawings, it will be evident that although comparativelysimple and inexpensive construction has been provided for the attainment of the desired results, the invention will be highly efficient and durable and will possess a number of advantageous characteristics.
