To all whom itmay concern:

Be it known that LOHARLES E. R. SCHNEI- DER, a citizen of'the United States of America, and resident of New York, in the county of New Y ork and State of New York, have inventedcertain-new and useful Improvements in Apparatus for Showing Pictures in Relief, of which the following i s a full, clear, and exact description.

- This invention relates to improvements in apparatus for the exhibition of pictures for amusement purposes, the object thereof being to acquire-visual effects of'great interest andattractiveness especially occasioned by imparting the aspect of bulk and reality to the projected image and the distance of such'image relatively to the showing which is also made,-apparently as a background, of a landscape oraccessories.

The invention as carried out on a stage in a theater, playhouse, or hall comprises a transparent plate mounted at an inclination to the line ofvision of the people in the audience, a screen behind the plate and a projecting machine or machines, such we moving picture machine or a stereopticon, or both, to be alternately or simultaneously used for the projection of the moving or still pictures.

The apparatus, furthermore, includes a sheet such -as canvas or other suitable matedepicted thereon, such sheet having its location opposite the glass plate, and by reason of being brightly illuminated is operable to cast the reflection of the landscape scenery oraccessories onto the transparent plate;

The invention is described in conjunction with the accompanying drawings and is set A forth in the claims.

In the drawings :-Figure '1 is a sectional elevatio n, more or less diagrammatical,

showing the preferred combination and arrangement *of partsvfor acquiring the de sired visual and illusory effects, Fig. 21s

a plan view as seen below the line 2-2, Fig.

1. is an inverted plan .viewof anoverheadla'ndscape bearing sheet.

As shown in the drawing, on a stage S is arranged a vertical screen 1%, suchas is usually provided to receive the projection from' or other projecting apparatus, placed at the rear of the auditorium, such as on a balshow a set of lightsv C on each side,

B will be visible to the audienceyas indicated.

In front of the screen B is arranged an inclined'plate A of suitable. transparent ma terial, such as glass. This plate 'A'is shown October 5, 1914. Application for as inclined rearwardly, at an angle of about f 45 degrees to the screen B, and to the horizontal floor of the stage. This plate A is arranged to intercept the rays projected on the screen B by the projecting apparatus, but by the well known laws of optics, these rays w1ll pass-through the glass plate, and

will be received on the screen B in the usual suitable image surface, shown in the present arrangement inthe"form of a sheet orplate D substantially horizontal, which is arranged-vertically above the .plate A. On the image surface D is applied alandscape or scenery of any desired form. A landscape, scenery or accessories is painted 011' otherwise produced on this surface D. It will be understood that if this scenery is illuminated, the reflecting-plate A will cause the light rays from the scenery at the image surface D, to be projected forward-horizontally and received by an observer in the audience, who is located at Special means are preferably provided to illuminate the scenery on the image surface D, and I os'i tioned a short distance below the stage door, so thatthese lights will reflect upwardly and illuminate the image surface D, but will not impingelon the. screen 13'. The light ray from a given point F on the image surface D, will strike a point G on the inclined plate A ,and be reflected forward on a line or path -I'I to' the observer at E. v In like manner a light ray fro na point J, onthe image sur face D, Wlll strike a point K, on the reflecting surface A, and pass along a path L to the observer, It is wellknown that reflected,

rays appear to the observer in a continuap ,tion'of their path from the reflector to the a motion picture mach1ne,"or. stereopticon,

observer, and appear on an extension of such latter path, and as far beyond or-back'of the reflectingjsurfacaas such my travels from V the image the reflecting surface; From gnnt to point in the image, and therefore the scene; I

this it'- follows that the point F, will a pearto the observer in the line or path at a oint M, the same distance from the point as is the point F. Likewise the point J,

will appear to the observer in the path L,

at a point N, a distance removed from the K equal tocthe distance from the point the point J. This applies to every on the ,image surface D will appear at a locus M-lT. "But this locus is beyond or to the rear of the screen 'B upon which the image is projected by the projecting apparascenery on the image surface at D will be projected at the same time into the eye of the observer at E, but for the reasons set forth, this scenery will appear to the observer to be located some distance to the rear of the screen 13, at the locus M-N. This will give a plastic or stereoscopic eifect, and Wlll create a very strong and life-like illue sion having the aspect of bulk or relief, similar to that produced b the instrument known as a stereoscope. T e images in mo-' tion willactually appear as it moving some distance in front of the scene For the reasons stated, it will be understood that the projection of the scenery or image surface from the sheet at D, will he apparently located at the locus M'N, and the distance that this imageappears beyond the screen B, is determined by the distance that the image surface.D is located above the reflecting plate A; it being" understood that the screen B is much nearer to the plate:

A than is theimage surface at D. I
