SPECIFICATION forming part of Letters Patent No. 676,822, dated June 18, 1901.

Application filed June 1, 1900- To all whom it may concern.-

Be it known that I, LUDWIG NEUMAYER, a subject of the German Emperor, and a resident of Merseburg, Germany, have invented certain new and useful Improvements in Advertising-Vehicles, of which the following is a specification.

The object of my present invention is to provide an advertising-vehicle the back and sides of which are made of transparent material, the advertisements or the like being projected upon the back wall by means of de vices arranged in the interior of the vehicle.

In the accompanying drawings, forming a portion of the specification, Figure 1 is a vertical sectional view, and Fig. 2 is a horizontal sectional View, of the improved advertisingvehicle.

The side and back walls of the vehicle are formed of plates a, made of glass or other transparent material. The vehicle contains a magic-lantern b, which projects the advertisements upon the back wall, as above stated. The advertisements may be stationary or changed and varied by means of plate 0, which may be moved forward automatically by means of any suitable device. The plate a in construction and operation is exactly similar to the slide of an ordinary magic-lantern, and therefore needs no special description. Movable advertisement-pictures may also be substituted therefor. The side Walls of the vehicle are protected from the light of the lan- Serial No. 18,753. (No model.)

Said lamps may be of different colors, and devices may be provided to enable the same to be cut in and out, as desired, during the progress of the vehicle.

Z Z represent the currentcouducting Wiresa The vehicle may be moved in any desired way and constructed in the form of a motorcar.

Having fully described my invention, What I claim, and desire to secure by Letters Patent, is-

The improved advertising'vehicle comprising transparent side and back walls made of suitable material, alantern in the interior of the vehicle and adapted to project advertisements upon the back wall of the vehicle and intermediate walls protecting the side walls from the light of said lantern, said side walls being lighted or illuminated as desired, by means of electric incandescent lamps, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of twowitnesses.
