ABSTRACT:
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.
