Abstract
530,617. Ink-ribbon mechanism. ROYAL TYPEWRITER CO., Inc. April 13, 1939, No. 11282. Convention date, April 25, 1938. [Class 100 (iv)] A hectograph or similar ribbon is fed line by line from a supply spool at the end of the carriage along the printing- line and between two serrated feedrollers at the other end of the carriage. One of the feed rollers has a fixed axis, the axis of the other roller being pivotally and slidably movable but able to be locked in its operative position. The rollers are driven unidirectionally by gearing and pawl-and-ratchet mechanism from a spring drum actuated by a band passing once round it and having its other end attached to the typewriter frame. A ribbon 22, Figs. 1, 2, is stored on a spool 27 on the carriage B and is directed along the printing line by guides 23, 31 ... 33, passing between serrated feed-rollers 48, 49. Roller 48 meshes with roller 49 and is driven by pawl-and-ratchet gearing from a drum 63 having a tape 79 anchored thereto and passing around not more than once, extending around idlers 80, 81 longitudinally of the carriage and finally round an idler 83 to a connection 85 on the frame of the machine. Roller 49 is mounted to revolve free on a pintle attached to a slotted arm 59 held in contact with the shaft 13 by enlargements on the roller shaft and a slot in the down-turned flange of shaft 13. A spring 55 urges the rollers together but they can be held apart by a notch on arm 59 engaging a notch on the carriage. The Specification as open to inspection under Sect. 91 states also that in an alternative mechanism, the feed rollers are actuated by the line-spacing lever 14, Fig. 10 (Cancelled). A toothed segment 89 is attached to an extension of lever 14 and engages a speed-multiplying gearing 91, 98 including pawl-and-ratchet mechanism to give a unidirectional drive which is transmitted to the roller 48. This subjectmatter does not appear in the Specification as accepted.
