Abstract
A cartridge for housing a supply of ribbon for typewriters or like machines. The cartridge includes an arm extending therefrom to guide the ribbon from the cartridge to the typewriter print point and to reverse the direction of the ribbon for guiding the ribbon back to the cartridge which is supported on a machine rigid frame on one side of the print point. The arm is provided in several embodiments of the invention, with a tab-like extension near its end to be engaged by the typewriter lift mechanism whereby it may be driven by the lift mechanism to carry the ribbon from a point adjacent the print point to the print point as a ribbon vibrator.
