Abstract

118,721. Akinine, A. Oct. 18, 1917. Optical-projection apparatus.-Kinematograph or other pictures are projected on to a frosted glass screen 3 and the image produced by a concave mirror 17 of the projected picture is viewed by reflection in a mirror 12. The mirror 17 is placed so that the screen 3 lies between it and its focus. The screen 3 may be carried by stays 7 hingedly mounted on a slide 5 movable in guides 6 on a table 1, and the mirror 12 may be carried by supports 11 pivotally and slidably mounted in slots in arms 8 hinged to the stays 7. The mirror 17 may be carried on a slide 14 in the same manner as the screen 3.
