Abstract

2372. Bartlett, S. G. March 13. Kinematograph apparatus.- In apparatus in which the film d is unwound from its inner end for projection and rewound on a receiving-spool ready for fresh projection, the spindle c of the delivery spool acts as a guide, and one disk g<2> of the receiving-spool is connected to a conical member g<3> so that, on unscrewing, the hub k can contract.
