e claims. (ci. fio- 133) -This invention relates to new and useful improvements in signs.

One object of the invention is to provide an improved sign wherein the background behind g the indicia, symbols, lettering or other display ,.characters, may be illuminated so as to produce a brilliant glow around said display characters, whereby said characters are more visible and the sign made more attractive.

li@ An important object of the invention is to provide an improved sign including a background having display characters spaced from said background, with means for projecting a colored light onto the back of the display characters, where- 'ti by the light is reflected on said background to produce a brilliant glow outlining the characters. l

Another object of the invention is to provide an improved sign wherein the indicia or display characters are spaced from-a background having ,3g openings therein, said openings being in alinernent with the display characters so that light may be projected through the openings onto the back of the characters; there being a colored medium interposed being the light source and the background, whereby the light passing through the openings is colored so that regardless of the angle from which the sign is viewed, only the colored light or its reflection is visible.

A further object of the invention is to provide an improved sign ofthe character described,

wherein the light projected through the background onto the back of the displayl letters may be colored by any suitable medium such as colored transparent paper, colored glass or the like,

which permits the coloring medium to be readily changed to quickly and easily change the coloring effects of the sign.

A construction designed to carry out the invention will be hereinafter described, together with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in

which an example of the invention is shown, and

wherein:

Figure 1 isa perspective view, with portions thereof broken away, of a sign constructed in accordance with the invention,

Figure 2 is a transverse, vertical sectional view of'the same,

Figure 3 is a partial sectional view of a slightly modified form of the invention,

Figure 4 is a perspective view of another form oi the invention,

Figure 5 is a transverse, vertical, sectional vie of the same, and Y Figure 6 is a reduced vertical, sectional view of still another modification of the invention.

ln the drawings, the numeral I0 designates a 5 lightreflecting housing or box which is provided with a plurality of electric lamp sockets l I therein. Electric lamps or bulbs l2 are mounted in the sockets and light the interior of the housing or box. The front side of the housing is open 10 and the shape of said housing is such that the light is reflected or projected forwardly through this open side.

A peripheral flange i3 surrounds the open front side of the housing and is directed forwardly 15 therefrom, vas is clearly vshown in Figure 2. A shoulder it is formed at the inner end of said flange and, a background panel or sheet I5 is adapted to be inserted within the ilange so as to abut said shoulder. The panel is preferably 20 constructed of glass and completely closes the open side of the housing. An outer display panel i6, also preferably constructed of glass or other transparent material, is inserted within the flange I3 and is spaced from the background g5 panel I5 by spacing strips I1 which may be secured in place by screws I1 which pass through the flange I3, or in any other 'suitable manner. An angular retaining frame I8 engages overv the outer end of theange I3 and has one leg 30 I8 overlying the marginal edge portion of the display panel to hold said panel in place within the flange I3. The other. leg of the retaining frame extends contiguous to the' cuter surface of the flange I3 and is suitably secured thereto, 35 preferably by the screws I1 which pass through the flange and into the spacing strips I1. With such arrangement, the panels I5 and I6 4are rigidly and securely fastened in the light reilecting housing or box and may be readily removed o for replacement or for any other reason by merely removing the retaining frame I8. Itis noted, however, that the panels may be mounted in said housing in any suitable manner.

In carrying out the invention, the indicia, symbols, or other display characters, are applied to the inner surface of the display panel I6 in any desired manner, as by painting, or otherwise. As shown in the drawings, the indicia are in the form of letters 20 which spell a desired word or 50.

words and are painted on the inner surface of the panel I6, an opaque paint being employed so that light striking said letters cannot pass therethrough. Since the panel is constructed of glass or other transparent material any light u.

projected from the housing I Il is visible therethrough except through such portion covered by the letters, whereby said letters stand out in. silhouette.

For controlling the projection of light from the interior of the housing through the display panel I6, the background panel or sheet I5 has its outer surface coated with an opaque paint or other substance 2|. This coating covers the entire surface of the panel except for those portions 22 which are directly behind the opaque characters or letters on the display panel I6. The uncoated portions take the form of the letters in alinementv therewith and are narrower in width whereby when the sign is viewed from the front the letters-20 completely hide the uncoated portions 22 and only the opaque background 2| with the letters 20 overlying the same, is visible. 'I'he light from the interior of the housing is projected through the uncoated portions 22 of the background panel I5 and strikes the back oi' the characters or letters 20 on the display panel I5, and is then reiiected onto the background 2 I. If desired, the back of each letter 20 may be coated with White or silver paint so as to increase the reflection. As the reflected light strikes the opaque background 2|, a brilliant glow is produced which clearly outlines the letter to make the same clearlyvisible.

In order to produce suiiicient reection it has been found that the panels I5 and I6 must be spaced some distance apart and this spacing makes the uncoated portions 22 on the panel i5 visible when the sign is viewed from an angle. Therefore, it is desirable to project a colored light from the interior of the housing through said uncoated portions, whereby the light passing through the portions 22 is of the same color as the reflected light 'which strikes the background 22 ,and thus, regardless of the angle from which the sign is viewed, the same color is al ways visible. Heretofore, it has been the practice to project a plain light through openings in the background and to paint the back of the display characters with the desired color and in order to obtain sufficient reflection, the spacing between the background and letters must be comparatively great, in which case the white light passing through the openings is visible when viewing the sign from an angle. The visibility of this white light as well as the colored reflected glow on the background ruins the eectiveness o! the sign.

In order to project a colored light through the uncoated portions 22 so as to avoid the above disadvantages, a transparent colored medium 23, which may be Celluloid, Cellophane, or the like is secured to the inner surface of the panel I5. This medium may be attached to the panel by gluing, or other suitable means and manifestly, the light passing through the uncoated portions 22 must pass through the colored medium. whereby the light rays striking the back of the letters 20 is colored. Therefore, when the sign is viewed from an angle, only a colored light is visible and a most effective sign is produced.

Although the colored medium is preferably some transparent material which may be suitably fastened to the inner surface of the panel I5, other means of coloring the light rays may be employed. For example, as shown inFigure 3, the uncoated portions 22 of the panel may be covered with a transparent colored paint 24, whereby the rays striking the backs of the letters 231s colored. It is pointed out that various means may be provided for coloring the light rays prior to their passage through the panel I5 and so long as the coloring medium is interposed between the light source and the panel I5, the purposes of the invention are accomplished.

In Figures 4 and 5, a modied form of the invention is shown. In this form the glass panels I5 and I6 are omitted and a background sheet or panel is secured to a framel 3| which is fastened to the open side of the light reflecting box I0. This background panel may be made of Wood, heavy cardboard, or the like and is provided with openings 32 therein, through which light may pass. Display characters or indicia 33 are cut out fr om a solid piece of material such as wood and are formed with a strip or bar 34 at their lower ends. The bar is secured to the outer surface of the background panel 3, which spaces the indicia from said background. Ihe openings 32 in the panel 30 coincide with the display characters 33 and a transparent coloring medium 23' is secured to the inner surface of the panel to cover the openings. The colored light rays strike the rear side of the characters and cast a brilliant glow on the background, silhouetting the characters.

The display characters may be mounted in the sign shown in Figures 4 and 5 in another manner, as disclosed in the lower display characters 35 shown in this sign. In this case the characters 35 are cut out of the panel 30 and a background strip 3S is secured to the inner side of the panel. This strip has openings 3l complementary to and in alinement with the characters and these openings are covered by the transparent coloring medium 223. Manifestly, the same eiect is produced with this structure.

As above pointed out, the medium which is interposed between the light source and theopenings in the background is subject to variation and, as shown in Figure 6, a colored glass plate or panel di) is inserted between the light bulb I2 of the housing and the background panel il. The coloring of the glass, of course, colors the light rays which are projected onto the back oi' the display characters. In all forms, the light rays passing through the background openings are of the'desired coloring.

It is noted that the light need not be provided by an electric lamp as shown, but any suitable source of light may be employed: It has been found that sunlight passing through the background panel is sufficient to create a glow on the background so as to enhance the appearance of the sign. Further, the particular openings in the background panel are subject to variation and by providing suflicient openings, it would be possible to produce a glow which would cover the entire surface of the background panel insteadof merely outlining each letter or character.
