Abstract

484,811. Projection screens. ETBAUER, T. P. Nov. 13, 1936, No. 31087. [Class 97 (i)] Apparatus for obtaining stereoscopic views of pictures of all kinds comprises in combination a picture, or a projection-screen, one or more transparent refracting bodies or grating- like bodies inclined at an angle to the picture plane, and a frame-like mask arranged in front of the picture plane. As shown in Fig. 1, the picture plane 1, which may be of a screen on which an image is projected by the projector, is inclined to the vertical and has placed before it two curved refractory bodies 4, 5 and masks 3 and 6. In the modification shown in Fig. 3, the picture may be projected on a translucent screen 7 by the projector 2b or on a transparent screen 7a by the projector 2a, the image being viewed in a reflector 1 before which is a mask 9 and an inclined refracting body 8. A second mask 10 may be provided, and grating-like bodies, such as fabrics or grids, which may be on or in transparent refracting material, may be used instead of the refracting plates.
