ABSTRACT:
The mechanism of this invention deals with a series of gears for sequentially moving and controlling a pair of blade-like members associated with a liquid applicator roller, one of said blades serving to wipe excess liquid from the surface of the roller, and the other blade serving to press a sheet of paper against the applicator roller in order to transfer the metered amount or controlled amount of liquid from the roller surface to the paper. The gear train includes a manually movable gear for rendering operative a sequence control gear for bringing the blades into contact and out of contact with the surface of the roller, which sequence control gear has associated with it various linkage members and latching members for holding the blades in position against the surface of the roller and for triggering the drive motor for rotating the liquid applicator roller.
