Abstract

413,060. Kinematograph and other spools. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and LUCAS, G. S. C., 75, Eastlands Road, Rugby. March 3, 1933, No. 6534. [Class 97 (i).] A strip of spring material 1, for use in attaching a flexible strip to a spool, has a natural shape such that one end will grip round the hub 3 of the spool for more than half, but less than the whole, of its periphery, and the other end 4 will extend beyond the cheeks 5 of the spool for attachment to the strip. As shown, the end 2 of the strip is formed as a hook to engage a slot in the hub, and the end 4 as a hook to engage the strip. A tongue may be pressed from the end 4 of the strip in substitution for the hook.
