Stuffed Take Up with Separator

Take-up of a typewriter ribbon by stuffing is positive and reliable where a flexible separator prevents the stuffed ribbon from becoming entangled with the supply mechanism.

The drawing shows a typewriter ribbon cartridge with a supply spool 1 mounted for unwinding rotation in the cartridge. Ribbon 3 exits the supply spool area through port 5, is guided by internal posts 7, and exits the cartridge through port 9.

Ribbon 3 extends outside the cartridge, where in use it is mounted to be typed upon, and enters the cartridge through port 11. It is guided across a post 13, and then enters the nip between gear 15 and gear 17, having outer gear teeth in mesh.

Ribbon 3 is firmly grasped by the meshing teeth of the gears. At each ribbon feed operation during typing, one of the gears is positively turned a predetermined amount by mechanism in the typewriter. Take-up of the ribbon is by the gears stuffing the ribbon randomly into the cartridge.

A flexible separator 19 is a thin elastomer (rubber) attached to the cartridge internally. Separator 19 at all times prevents the stuffed ribbon from entering the area occupied by the supply ribbon while being moved by the push of the stuffed ribbon to allow the space for receiving the stuffed ribbon to increase as the supply ribbon is used. Additionally, separator 19 prevents jamming of the stuffed ribbon into the exit port 9.
