Abstract

565,901. Spools for photographic films. MITCHELL, J., and HORTON, A. G. June 11, 1943, No. 9433. [Class 98 (i)] [Also in Group IX] A loaded spool of photographic film comprises two cylindrical coremembers 1, 2, flanges 3, 4 secured to one end of each core-member, means such as a bayonet joint 6, 7 for locking the other ends of the members 1, 2 together to form a spool having a composite core of uniform diameter, and a hollow cylindrical outer core having a coil of photographic film wound thereon which forms a close fit over the assembled core 1, 2. To reduce any tendency to slip the hollow cylindrical core is formed of slightly compressible material and its axial length is slightly greater than the distance between the flanges of the assembled spool. A pin 8 may be provided to engage a slot in the hollow cylindrical core and prevent its rotation on the core 1, 2.
