Abstract

250,183. Rouiller, A. April 4, 1925, [Convention date]. Kinematograph apparatus. - A long flexible endless film or band is spirally coiled within a casing and has a loop portion extending between the outermost and innermost convolutions, means being provided for feeding the band. As shown, the band c has feed perforations and is fed by sprockets e, g through air-tight passages d, h into and out of a box having a cover b. Radial screw-threaded rods f are rotated by any suitable means i so that the bottoms of the threads have a circumferential velocity equal to the velocity imparted to the band by the sprocket.
