To all whom it may concern:

Be it known that I, THEODORE Knman, a citizen of the United States, residin at New York city, "n the county of New ork and State of New York, have invented certain new and useful Improvements in Changeable Signs, of which the following is a specification.

My invention relates to signs particularly useful for advertising purposes, of such a nature that on viewin the sign from the front thereof a certain representation is visible when thesign is illuminated from the front only, and this representation, together with an additional one, is visible whenthe sign is illuminated fromv the rear thereof. V I v The representation visible when the illumination is from the front only, hereinafter called the front representation,

may bear different relation to the additional representation, hereinafter called the rear representation, and also to the combination of these two representations, hereinafter called the complete representation.

. For example, the rear representation may appear as a mere addition to the front representation in the complete representation; or in the complete representation the front and rear representations may be merged, at least in part, one in the other. Furthermore, there may be an omission in either the front or rear representations, generally and preferably in' the rear one, to correspond with the front representation, or at least apart thereof; or there may be no such omission.

Referring to the drawings:

Figure '1 is a front plan view of my sign.

Figure 2 is a vertical cross sectional view thereof.

Figures 3, 4 and 5 show the pictures used in advertising a shoe, Figure 3 showing the picture appearing on the front of the screen, igure 4 showing the picture appearing on the rear of the screen, and Figure 5 showin the combination of the two.

igures 6, 7 and 8 show pictures used in advertising a cigar, Figure 6 showing the icture appearing on the, front of the screen, igure 7 showing the picture appearing. on the rear of the screen, and Figure 8 showin the combination of the two.

ferrin nates a suitable box or frameworkv having to Figures 1 and f2, 1=desigan open front 2 within which my advertising cards are ositioned. The box may be closed except or thisopening, and suitably located within the box are illuminating devices, such as electric lamps 3 which may be alternately flashed on and off by means of any suitable flasher, which is not shown,

duce a change in color asthe lights areflashed, or the sock on the rear picture may be merely an outline without any coloring, and the same is true of the representation of the trousers on the'rear picture. A shoe "7 appears as worn over the sock on the rear picture and this is generally so colored, that it is generally darker than the color of the sock, the color of the shoe being such that on flashing the light to make the combination of the front and back picture. visible, the part of the sock within'the shoe .will become merged therein and substantially apparently invisible.

It is, of course, obvious that the posi-' tions of the front and rear pictures may be interchanged when so desired; that is, the picture illustrated in Fig. 3 may be located at therear and that illustrated in Fi 4 may be located at the front.

herear picture is located immediately behind the front picture in such a manner, that on flashing the lights, the two pictures will blend into one and appear as shown on Figure 5.

It is generally best to have the rear picture .as close as possible to the front picture and for that reason I prefer to have the front picture on one side of the translucent sheet andthe rear picture on the rear side thereof, although if desired, a separate sheet may be used for each picture, thus permitting of some variations in the combined composite icture.

In t e modification, illustrated in Figjures 6, 7 and. 8., a cigar 11 appears upon the Application for i 1 as it forms no part of the invention. The

. and 5, the front f ont picture and this may be surrounded bfy a white or other background 12. The

rear picture may comprise the representation of a man 13 holding a lighted match 14 in his hand 15, and the background 16 may be suitably colored as desired. Suitable wording 17 may appear upon the rear picture and this may be done either by the addition of suitable letters, or by the omission of the background, ifv a colored background is made use of. The rear picture is directly behind the front picture and there may be an omission 18, if desired, on the rear picture to correspond with the cigar on the front picture, so that when the lights are flashed on, the combined picture as shown on Figure 8 will be visible. Here again, should it be found desirable, the front picture may be located at the rear and vice versa, so that the picture illustrated in Fig-' ure 6 will be the rear picture, while that illustrated in Figure 7 will be the front picture. All or a part of the rear picture may be made opaque, as shown for example at 19 on Figure 4, so that it will appearv as a shadow on the combined picture when the illumination comes from the rear as a shadow.

The modifications described above are given merely by way of example and the invention is not. to be considered as limited thereto, a number of variations being possible within the scope of my invention.

What I claim is:

1. A changeable advertising sign consisting of a casing of opaque material and having an open side, lights within said casing, a translucent sheet closing said open side, a representation which is complete in itself but which does not include a representation of the article to be advertised at one side of said sheet and a representation which ineludes a representation of the article to be advertised and which is supplementary to the first mentioned representation at the other side of said sheet, only one representation being visible from the front when the lights are out and the combination of both representations being visible from the front when the lights are on, the combined representations when. viewed together from the front when the lights are on forming a com- 'lete clean-cut picture registering as to all 1ts parts whereby the periodic operation of the lights causes two clean-cut pictures to be seen in alternation from the frontof the sign, one of said pictures being the representation of something which lacks a feature, said feature which is lacking in the one picture appearing in the other picture, one of which pictures comprises a representation of a thing and the other of which does not comprise the representation of said thing, thereby showing alternately the representa- 66 tion of a thing in operative relation t0 some other thing and then the representation of one of the things without the other thing.

2. A changeable advertising sign consistingof a casing of opaque material and having an open side, lights within said casing, a translucent sheet closing said open side, a representation which is complete in itself but which doesnot include a representation of the article to be advertised at one side of said sheet and a representation which includes a representation of the article to be advertised and which is supplementary to the first mentioned representation at the other side of said sheet, onlyone representationbeing visible from the front when the lights are out and the combination of both representations being visible from the front when the lights are on, one of said representations at the part corresponding to the article to be advertised overlapping and being at least as dark as a portion of the other representation so that when both representations are viewed together from the front when the lights are on, the overlapping part of one representation seems to disappear and is blended and merged in' the overlapping part of the other representation, the combined representations when viewed together from the front when the lights are on forming a complete clean-cut picture registering as to all its parts whereby the periodic operation of the lights causes two clean-cut pictures to be seen in alternation from the front of the sign, one of said pictures being the representation of something which lacks a feature, said feature which is lacking in the one picture appearing in the other pic ture, one of which pictures comprises a representation of a thing and the other of which does not comprise the representation of said thing, thereby showing alternately the representation of a thing in operative relation to some other thing and then the representation of one of the things without the other thing.

3. A thangeable advertising sign consisting of a casing of opaque materia and having an open side, lights within said casing, a translucent sheet closing said open side, said I translucent sheet having a representation 11! which is complete in itself but which does not include a representation of the article to be advertised on the front side thereof, and a representation which includes a rep resentation of the article to be advertised and which is supplementary to the first mentioned representation immediatel behind said sheet, only the first mentioned re resentation being visible from the front w en the lights are out and the combination of both representations being visible from the all itsparts, whereby the periodic operation of the lights cause two clean out pictures to be seen in alternation from the front'of the sign,. one of said pictures being the representation of something which lacks the article to be advertised and the other of said pictures being the representation ofsaid thing supplied with the article to be advertised in operative relation thereto.

4. A changealble advertising sign consisting of a casing of opaque material and having an open s1de, lights within said casing, a translucent sheet closing said open side, said translucent sheet having a representation which is complete in itself but which does not include a representation of the article to be advertised on the front side thereof, and a representation which includes a representation of the article to be advertised and which is supplementary to the first mentioned representation immediately behind said sheet, only the first mentioned representation being visible from the front when the lights are out and the combination of ear and is blended and merged in the overappinggmrt of therear' representation the comblne representations when viewed together from the front when the lights are on forming a complete clean cut picture registering, as to all its parts, whereby the periodic operation of the lights cause two clean out pictures to be seen in alternation from the front of the sign, one of said pictures being the representation of something which lacks the article to be advertised and the other of said pictures bein the representation of saidthing supplied with the article to be advertised in o erative relation thereto. 7 T ODORE KELLER. v
