Abstract

The number of characters that can be printed at a printing station is increased by using a pair of printing elements each having a number of flexible character bearing fingers. The printing elements are disposed in overlying or nesting relation which permits any selected character on the printing elements to be positioned at the printing station.

Printing Elements

The number of characters that can be printed at a printing station is increased by using a pair of printing elements each having a number of flexible character bearing fingers. The printing elements are disposed in overlying or nesting relation which permits any selected character on the printing elements to be positioned at the printing station.

Printing disks 10 and 11 each have a plurality of extending flexible fingers 12 and 13 which carry characters 14. Disk 10 has a radial slot 15 in it which is larger than any finger 13. The printing disks are rotatably mounted and are positioned in axially aligned relation adjacent a printing station defined by hammer 16. To print a character from disk 11, disk 10 is first rotated so that slot 15 is disposed adjacent the printing station. Disk 11 is then rotated to position the selected character adjacent the printing station and hammer 16 deflects the selected finger 13 through slot 15 to print the character.

Another arrangement comprises a pair of concentrically mounted type cylinders 18 and 19 having flexible fingers 20 and 21. Outermost cylinder 18 has a slot 22 in it which permits hammer 23 to deflect the characters on fingers 21 of inner cylinder 19 into printing relation with paper disposed at the printing station.

The character capacity is further increased by providing more than one row of characters on each printing element as indicated at 25. Such an arrangement requires apparatus, not shown,...
