  • Patent number: 4407579
    Abstract: A photographic film assemblage wherein a film spool which supports a roll of film is comprised of two pieces constructed so as to telescopically receive each other. Each piece includes a radially extending flange which is adapted to be located closely adjacent to but not in engagement with a side of the roll of film. The spool is rotatably supported within a housing having a lighttight passageway through which a leading end of the film may extend to the exterior of the housing. To move the leading end into and through the passageway so as to make it available at the exterior of the housing for connection to a film winding mechanism, one merely applies inwardly directed pressure to the opposite ends of the spool so as to move the flanges into contact with the sides of the roll of film.
