Abstract

423,019. Kinematograph apparatus. COULLERY, H., 56, Rue Numa Droz, La Chaux de Fonds, Switzerland. July 26, 1934, No. 21910. Convention date, July 27, 1933. [Class 97 (i)] In apparatus in which the images are spirally arranged on a disc having spirally arranged perforations, the disc is rotated and translated by an intermittentlyrotated wheel having teeth or pins engaging the perforations. As shown, a film disc 1 is held between plates 4, 5, respectively carried by a casing 6 and its hinged cover 7, and has a central perforation engaged by a pin 10 on a slide 11 movable along a slot in the plate 4. A wheel 8 has pins engaging the feed perforations and is carried by a shaft 9 rotated by hand or motor through an intermittent mechanism. The wheel 8 is located in a light passage 14, and a magnifying glass or objective 13 is provided on the cover 7 opposite the passage.
