ABSTRACT:
A typewriter ribbon cartridge includes a housing having an upper wall with side walls extending therefrom. The upper wall is formed with two spaced apertures therein. A takeup spindle is fitted with its first end receivable in one aperture in the upper wall, and a ribbon supply spool is fitted with its first end supported for rotation in the second aperture. A supply spool platform is attached to the end of the supply spool remote from the upper wall and rotates with the supply spool. Typewriter ribbon is connected between the supply spool and the takeup spindle with a supply of ribbon wound onto the supply spool. A cover is supported from the side walls extending from the housing, and receives the second end of the takeup spindle such that the spindle is rotatively supported between the cover and the upper wall of the housing.
