  • Pressure roller assembly
    Patent number: 4786193
    Abstract: A truck assembly unit has two identical parts which lock together capturing two rollers. The truck assembly unit is supported on a cylindrical portion of a support bar so that it can rotate through a limited range, the range being limited by a ridge running along the bar. The bar is affixed eccentrically on journals captured in the frame of a typing machine so that rotation of the bar moves the supported truck assembly towards and away from a platen. Arms supporting the rollers provide flexure to bias the rollers against the platen.
