Abstract: A set of selectively active stop pins cooperate with measured openings in a control plate to limit letter feed motion in either the forward or reverse direction. The measuring plate opening includes two effective portions that are alternately selectable to provide two different measuring calibrations. A preferred alternate calibration is known in the art as ''''EXPAND'''' where all measurements are increased by a fixed amount. Fixed increment spacing is obtained by suppressing the measuring pin selection through an override device, thereby allowing control to be accomplished by a normally active measuring pin in cooperation with the measuring plate. By providing all measuring mode control at the measuring plate, it becomes unnecessary to modify the space control information generated in the typewriter keyboard.

Abstract: A clamp (11) for holding a flexible sheet (12) on a rotary carrier (10) tightens the grip on, and pulls, the sheet upon rotation of the carrier, as a result of centrifugal forces generated on two weights (28, 29) attached to two cooperating arms (21, 22) within the clamp. The magnitude of the grip-tightening force is dependent upon the mass of a grip-tightening weight (28) attached to the clamp. The magnitude of the sheet-pulling force is dependent upon the mass of a sheet-pulling weight (29) attached to the clamp. The clamp faces (18, 19) are mounted (23) for concurrent movement along the periphery of the carrier to prevent tearing or other damage to the sheet when it is pulled as the carrier is rotated.
