  • Font strip structure
    Patent number: RE28785
    Abstract: The font strip consists of a dimensionally stable photographic film on which have been developed timing marks and type characters. The font strip is accurately positioned on a rotating drum by guide posts which project through apertures on the font strip. The font strip is secured to the surface of the drum by the engagement of an end plate fastened to one end of the font strip, which end plate projects through pins mounted to the surface of the drum. The other end of the font strip is bent within a hooked end plate which engages a correspondingly tapered hook portion of the font drum. A tensioning mechanism associated with the font drum affords the necessary tension to maintain the font strip on the drum.
