Specification of Letters Patent.

Patented June 19, 1917.

Application filed June 12, 1914. Serial No. 844,674.

My present lnvention is an apparatus for the reproduction and display of pictures, signs, advertising matter, or the like, and relates more particularly to an apparatus intended specially for use with a vehicle. My apparatus enables a reproduction of pictures,

designs, advertising matter and so forth, to

be shown at two or more points in the vehicle, preferably on each side thereof, so that both sides of the vehicle carry display screens, and thus the vehicle shows a reproduction of the matter so displayed on each side from a single set of pictures, thus appealing to twice the number of observers as was formerly possible. The advantage of this feature will be appreciated when it is realized that a single attendant can thus double the publicity of the matter desired to be displayed.

In carrying out the present invention, I prefer to arrange a vehicle with display screens on either side, and provide means which will duplicate simultaneously the pictures, advertising matters, designs, trade marks, or the like, which are to be shown, and furthermore to enable a third screen to be utilized, for example, across the extreme rear of the vehicle, on which a moving picture apparatus or the like may be focused from the interior of the vehicle, and the entire mechanism may be handled by a single operator.

A still further feature of my present invention of particular importance in the display of lettering as a part of the advertising matter, consists in means to rectify the image reproduced on one of the side screens so that the same will conform in position to the other. This I accomplish by means of a proper refraction of the rays of light projecting the image dis layed, through a series of reflecting sur aces or mirrors, and this feature is absolutely essential in the duplex display of lettering, in order to have the same read correctly when thrown on the two screens intended for view from diametrically opposite points, i. e. at either side of the vehicle.

Other features of the invention, novel combinations of parts, and details of construction will be hereinafter more .fully pointed out and claimed.

Referring to the drawings, wherein I have llustrated a preferred embodiment of the invention as applied to a moving vehicle,

Figure 1 is a side view of the vehicle carrylng my apparatus;

Fig. 2 is a plan view showing the vehicle sides, ends, and the screens in cross section;

Fig. 3 is an elevation of the rear end of the vehicle intended to carry a screen to rece1ve the images projected by the moving picture machine; and

F i g. 4 is a diagrammatic view of a modificatlon of the duplex projecting mechanism.

While I prefer to employ the apparatus constltuting the preferred embodiment of my present invention in connection with a moving vehicle, it will be understood that this is unnecessary, as the apparatus may be employed advantageously in a fixed location and utilized to display a plurality of reproductions from a single set of pictures,

Figs. 1 and 2, and with the remaining.

opaque portions of the sides 7 and 8 adapted to receive lettering, advertising matter or the like, as illustrated in Fig. 1. Adjacent the rear window 4 is a screen 9, of appropriate dimensions to receive the images projected by a moving picture machine 10, which is located within the body of the vehicle and illuminated from a source of light 11. The moving picture machine may be run either by an operator seated at 12, or may be continuously actuated by an electrical motor 13 run from a storage battery 14, as shown in conventional form in Fig. 2.

In order to show the display on each side of the vehicle, through the plate glass windows 5 and 6, suitable screens 15 and 16 respectively are provided adjacent said windows. Through these screens dissolving views may be displayed, being thrown on the back thereof and showing through, such screens being of translucent material, similar to the screen 9 already mentioned, as is customary. To duplicate the display of the same picture, from a single film on the screens 15 and 16 simultaneously, I arrange a system of reflectors 17, 18, and 19 angularly positioned with regard to a lens '20, through which lens is thrown an image from a dissolving view frame holder 21 by the same light 11 as is needed to operate the moving picture machine 10 and all within convenient reach of the operator at 12. The dissolving view frame 21 is of any well known style, similar to the Magic lantern, or stereopticon apparatus. \Yithin the holder 21 is a film slide 22, of sufficient length to receive two films, one being in position to throw the image through the lens 20 and the other being outside the frame holder 21 to permit the removal of an exposed film and the positioning of a new one, when the slide is operated to bring the new film in view and permit the exposed view to be removed. The image projected by the light 11 through the lens 20, striking against the reflector 17 throws the view on the screen 15, thereby displaying the same on one side of the vehicle. while the reflector 18, receiving the same view throws it first to a rectifying reflector 19. and thence to the screen 16, displaying the same on the other side of the vehicle. I may omit the reflector 19 where views, landscapes, or designs only are being displayed, as it is quite immaterial from the point of view of the observer on either side of the vehicle, how the landscape is thrown, whether in reverse. position or not. but when lettering is also displayed on the side screens, it is imperative that the lettering be shown correctly, and therefore I prefer to utilize the double reflectors 18 and 19, to rectify the projections displayed on this sidc, the views being positioned in the holder 21 for projection of the reading matter in proper alinement on the screen 15. I may desire to use one or more screens as toning screens, one such additional screen being illustrated at 23 in Fig. 2, and a plurality of such screens being employed if desired, through which the image may be thrown.

It will be understood that the duplex reproducing apparatus may be employed either with or without the moving picture machine 10, and may be also used with a similar dissolving view device for the rear screen 9.

In Fig. 4 I have illustrated a modified form of the invention. wherein the dissolving view frame holder 21 and lens 20 are angularly positioned to project the image on a reflecting surface 24, adjustably held at the top of the vehicle to throw the image received by it upon either side of double reflectors 25 and 26 to thereby project the image on the display screens 15 and 16. This form of the invention may be desirable in case the width of the vehicle is limited, or for any other reason.

My display apparatus, especially when. carried in a moving vehicle. constitutes an attractive advertising medium. displaying the same advertising matter to both sides of the street through which the vehicle )asses. thus increasing the number of the public reached thereby. and the rear screen continues to hold the attention of the public who have already witnessed the side views.

Having described my invention. what I claim as new and desire to secure by Let tcrs Patent is:

Display apparatus having mechanism to project three views of the same object from a single source of light, and means to display said views on a plurality of transparent screens simultaneously. one view being alined with the original projection and the other views being projected on screens at angles to the line of original projection, the projection on one of said screens being thrown by a plurality of rollccting surfaces to rectify the image displayed.

In testimony whereof. I have sigl'llttblll) name to this specification. in the presence of tWo subscribing witnesses.
