tured at a relatively low, cost as well as one which will require minimum attention dur-' ing operation and one in which the upkeep will be relatively small.

Another object of this invention is to provide an advertising device embodying an endlessfilm or tape which carries suitable letters or illustrations for expounding the merits of thearticle or articles advertised. The letters or illustrations of the film are transparent so as to permit the projection of light rays therethrough and also to provide means whereby the size of the letters or illustrations will be magnified upon presentation to view.

Other objects of the invention will appear in thefollowing detailed description and in the accompanying drawings wherein:

Fig. 1 is a horizontal section through the improved advertising device.

Fig. 2 is a vertical section through the advertising device on the line 2-2 of Fig. 1.

Fig. 3 is'a vertical section through the advertising device taken on the line 3-3 of Fig. 1.

Fig. 4 is a detail view of the taper-tensioning means employed in the advertising device.

Fig. 5 is a fragmentary detail of the film or tape employed in the advertising device.

Referring more particularly to the drawing the improved advertising devicecomprises a suitable cabinet or casing-1 which has a translucent front 2. The translucent front 2 is preferably made of frosted or colored glass, to add aesthetic value to the advertising device and the frame 3 surrounding this front 2 may resemble an ordinary picture frame of any desired artistic design.

Extending rearwardly into the cabinet or casing 1, from the translucent front 2 is a pyramidal reflector 4, the inner surface of which is painted a dull black or any desired to advertising deployment drive shaft 14.

dullcolor to prevent the projection of confuslng light rays. The base of the pyramidal reflector 4 is equal in size to the panel or front 2 and an incandescent lamp 5 is positioned at the apex of the reflector 4 and grrazlnged to project light rays into the reflec- The reflector 4 is provided with slots 6 and 7 in its edgeat directly opposite points and in close proximity to its apex and the indicia bearing tape 8 travels through these slots, being positioned between the light 5 and front or panel 2, as clearly shown in Figs.

1 and 3 of the drawings.

The tape or film 8 is opaque and has suitable letters or illustrations 9 thereon which are transparent. These letters" or illustrations 9 may becut in the tape to permit the projection of light there-through or they may be rendered transparent in any well known approved manner so as to allow the light rays, from the lamp 5, to be projected therethrough. owingl'mto the gradual increasing of the size of t e reflector 4 towards the transl cent front or panel 2 the size of the letters'or illustrations 9 will be magnified upon the front or panel 2. The tape or film 8 travels about a plurality ers 10and a driving pulley 11. The guiding rollers 10 are arranged to permit the emof a relatively long endless film or tape. The driving pulley-11 is driven from an electric motor 12 which is carried by the cabinet or casing 1 and connected to the drive pulley 11 by a countershaft 13 and Suitable power transmitting means, such as pulleys and a belt as indicated at 15, is provided for driving the.

driving shaft 14 from the countershaft 13. The drive shaft 14 has a worm 16 mounted thereon which meshes with aworm gear 17 mounted on the shaft 18 which carries the drive pulley 11.

One of the guiding rollers 10 is supported by a substantially U shaped bracket 19 which is, inturn, adjustably supported by a threaded stem 20. The stem 20 extends through 1 and has a thumb nut 21 upon its outer end by which the, stem is rotated for adjusting the position of the roller 10 carried by the bracket 19 to tension the tape 8. i v

Briefly, the operation of the improved advertising device is as follows:'

The driving pulley 11 is rotated from the motor 12 which causes movement of the tape of guiding rollor film 8 causing it to pass through the slots 6 and 7 and consequently through the reflector 4. As the tape passes through the reflector the light rays from the lamp 5 are projected through the transparent letters or illustrations on the tape causing the letters or illustrations to be reproduced on the translucent front or panel 2, and,'owing to the pyramidal shape of the reflector the letters or illustrations will be magnified as they are reflected upon the front'or panel 2 and as the tape moves through the reflector, the letters or indicia will travel across the front or panel2 starting at one end thereof and traveling across, dlsappearing at the op'posite end as they pass out of the reflector through the slot 6. i

It is, of course, to be understood that the in two of its opposite side Walls reachingfrom the top to the bottom of the reflector, an endless tape passing through the slots and of a Width substantially equal to the lengths and means for moving the tape.

In testimony whereof I affix my signature.
