摘要： A line feed ratchet arrangement is disclosed which allows selectability between two different line feeds such as the 5 1/3 lines per inch and six lines per inch and utilizes a drive pawl arrangement having two pawls driven identically. The drive ratchets are selectively engaged by coaxial shifting of a drive member in response to operator movement of a selector knob or similar control.

摘要： A typewriter-printer includes a single element printing mechanism which is pivotable about the center line of the curved platen to an optimum print line viewing position. Printing can thus take place, for example, along a print line located below the center line of the curved platen or, in the alternative, above the platen center line in accordance with operator adjustment of the printing mechanism. The printing mechanism is mounted for printing motion and is further mounted for escapement motion with respect to the stationary platen.
