Abstract

295,234. Kutassy, A. von. May 4, 1927. Optical-projection apparatus comprises an endless band of transparencies 9 which passes over rollers 10 to form a U-shaped path which is in the plane of and encloses the light beam 6 from the lantern 4, the beam being deflected into V- form by a mirror &c. 5. The images may be focused on a screen 8 in the side of the case 1, or on an external screen. The transparencies 9 are glass or film elements which are connected together by flat or circular eyes 16, and the round or polygonal rollers 10 are grooved to accommodate the eyes.
