Specification of Letters Patent.

Patented Feb- 23, 1808.

' Application filed March 27, 1908. Serial No. 423,497.

i ducing motion pictures, the moving bodies being concealed from view but the images thereof being projected upon the screen.

My invention involves a box or cabinet, having the major ortion of one vertical side thereof open and aving a plurality of mirrors arranged upon the inner surface of the Walls of the box or cabinet, so that the light rays from the bodies will be refiected and converged through a lens carried by one .Wall of the 'box or cabinet, so as to project the image upon the screen.

Reference is to be had to the accompany ing drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures, and in Which- Figure l is a vertical section through a dcvice constructed in accordance with my invention; Fig. 2 is an end view thereof, and Fig. 3 is a diagrammatic view, showing the relative arrangement of the moving bodies,

the cabinet and the screen.

vThe specific form of my im n'ovcd projecting apparatus illustrated in the accompanying drawings, includes a box or cabinet, having oppositely-disposed substantially parallel side Walls 10, abottom wall 11, a top wall 12, and front and back walls 13 and 14. The back Wall 14 is provided with an opening 15 extending from closely adjacent the bottom ofv the cabinet to closely adjacent the top v thereof, and of a Width substantially equal to 'gtintixlly vertical section 18,

upper end of the inclined section 17 by a t action 19 of the to the width of the cabinet. rflic front wall 13 .is Inadeup of a plurality of sections, including a lower 'substantially vertical section 16, an intermediate section .17, inclined to approximately `twenty-two and oncdialf dcgtew from the vertical, and an upper subconnectod to of the cabinet. 'lhe other section 2O of t el top of the cabinet connected to the rear Wall 14 at the upper edge of the opening 15, by a wall section 21, extending at approxiinatel forty-five degrees to the horizontal. T e inner surface ofthe wall section 17, which is directly opposite to the opening 15, supports a mirror 22, reflecting toward the opposite lower corner `of the cabinet, the light rays entering substantially horizontally through the openinv 15. l

hVithin the cabinet and at the rear lower corner, l provide a mirror 23, extending at an angle of approximately twentytwo and onehalf degrees to the horizontal, and receiving the light rays from the mirror 22 and reflectsv ing them upwardly toward the top of the cabinet, at substantially right angles to the )ath of the ravs entering the opening 15.

`he inner surface of the wall section 2],

carries a mirror 24, extending' at an angle f of substantiall r forty-live degrees to the horizontal, am 'receiving the light ra, from the mirror 23 and reflecting them sul)- stantially horizontally to a double convex lens 25 mounted in an aperture in the vertical wall section 18. surface of the box or cabinet, save that covered by the mirrors, are painted black, so that no light rays will be reflected save those which strike the mirrors.

ln the use of my improved projecting a iaratus, l place thc cabinet intermediate t e liodics, the images of which are to be pro jectcd, and the screen, wall, curtain, or other ground upon which the images are to be pro jcctcd. The bodies or subjects and the screen, arc preferably separated from each other by :in opaque wall 26, so that no light rays will roach the-screen save those passing through thc cabinet. This opaque Wall is provided withan opening therein, substantially registeringi with the opening 15 of thc cabinet. 'llhe persons, animals, figures, bodies, scenery, or other subjects, are placed at a short distance from the cabinet, as, for instance, upon a platform 27, and are illuminated, as, for instance, by artificial lights 2S. The curtain, screen, or wall 29, is in darkness, save for the light reflected thereon from thc mirrors and through the lens, but by reason of said mir rors and lens, the images of the bodies orsubjects on the platform '27, will be projected upon thc screen right side up, clear in outline, perfect in detail, and also in the natural colors. lf desired, the partition 26, .or the All portions of the inner 'horizoriteiiy through one side, will be projeoted substantially horizontally et mother rer, a, third mirror Within said. easing and re- Waiie or the cabinet, may be roede of Mack eioth, to ermit the speaking, singing. or music, of trie ersons ori tlie peticorm 27, to he heer. by t e persons Viewing the screen.

The appara-tus may be made any size desired., depemiiiig upon the size of the objects to te projeeted upon the screen and the sizel of the spiace evoiioioie. The mirrors may be errengedet different ongles, or be v9.- rier in number,it only being essentiel that the oebiriethave the mirrors and iene or iensee so arranged ori its interior Weils, that the `iight rays entering the cabinet substmitieliy side toward the screen.

thus described my invention, Gleim es new end desire to secure by Letters Patent:
