There is shown in US. Patent 2,986,260, issued May
30, 1961, to W. B. Whippo, a cartridge having a single
chamber in which two spools are rotatably supported at
their ends in top and bottom walls. An inked ribbon ‘is

then extends through a slot in the side wall at one end
of the cartridge. It passes along one side of the cartridge,
as shown in FIG. 1, and then enters a slot in the side
wall at the opposite end of the cartridge to be wound on
the other spool 13. When the cartridge is in use on a
typewriter, a driving spindle extends through one or both
of the openings 17 and 18 to engage each of the spools

ends of the spools are in alignment with openings in the
