Abstract

The present stuffer cartridge is designed for printers utilizing off the carrier ribbon supplies. The ribbon is wrapped around 45 degree angle surfaces as it enters and leaves the stuffer box. The 45 degree angle surfaces guide the ribbon in opposing directions when entering and when leaving the stuffer cartridge so that when passing through the stuffer cartridge, the ribbon is turned over, i.e., the bottom of the ribbon is where the top was. As the ribbon passes in front of the printwheel, it will be printed upon alternatively along the top and bottom on each alternative pass. This provides for uniform striking on the ribbon.

The present stuffer cartridge is designed for printers utilizing off the carrier ribbon supplies. The ribbon is wrapped around 45 degree angle surfaces as it enters and leaves the stuffer box. The 45 degree angle surfaces guide the ribbon in opposing directions when entering and when leaving the stuffer cartridge so that when passing through the stuffer cartridge, the ribbon is turned over, i.e., the bottom of the ribbon is where the top was. As the ribbon passes in front of the printwheel, it will be printed upon alternatively along the top and bottom on each alternative pass. This provides for uniform striking on the ribbon.

The ribbon cartridge 1 is inserted into the printer by the operator. It snaps into the side frame 9 in a vertical position by the use of a release spring 2 which is molded into the cartridge. The ribbon 3 is manually positioned around a guide on the opposite side frame (not shown) and in front of the print wheel 4. Slack ribbon can be adjusted out by the use of a finger take-up slot 5 located in the top of the cartridge. The printer is now ready for operation.

The ribbon is advanced through a series of gears by the leadscrew 6. It progresses from right to left in front of the printwheel 4 and enters the cartridge at the entrance 7. The printing takes place on the top half of the ribbon. As the ribbon enters the cartridge, it wraps around a 45 degree angle surface which directs the travel of the ribbon in a downward...
