Abstract
209,546. Cohen, S. Nov. 15, 1922. Cameras, roll-film; roll spools.-A camera for films of the kind comprising a number of spaced sensitized layers mounted on a paper roll, which may be severed between any two layers so that the exposed portion of the film may be removed, is provided with a back in which the part covering the exposed spool, but not carrying said spool, is hinged so that it can be lifted up to give access to that spool only. In the form shown, the part H, Fig. 2, of the camera back is hinged at K to give access to the exposed spool G, which carries separate films such as A, B, Fig. 1, mounted in spaced relation on a paper roll C so perforated at D, E that, on removal of the exposed portion, a tongue of paper is left adapted to fit into the slot usually provided in a spool. Marks are provided on the back of the film, adapted to register with the window in the camera back exhibiting the exposure number, to facilitate winding of the film into the correct position for severance.
