ABSTRACT:
A ribbon-feed and motion-reversal device for typewriters and the like comprises an oscillating supporting plate on which a cartridge with the spools carrying the inked ribbon is placed, the supporting plate being coupled to a driving lever driven by a cam mounted on the driving shaft of the typewriter, and suitable to transmit the winding action directly to either one of the ribbon-carrying spools of the cartridge. A balance lever is driven by the ribbon at the end of its unwinding, through oscillating wings on the cartridge.
