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 translation: 一组选择性的主动止动销与控制板中的测量开口配合，以限制正向或反向的字母馈送运动。 测量板开口包括两个有效部分，其可交替地可选择以提供两个不同的测量校准。 优选的替代校准在本领域中称为“扩展”，其中所有测量值增加固定量。 通过通过超控装置抑制测量针选择来获得固定的增量间隔，从而通过与测量板协作的常规测量引脚来实现控制。 通过在测量板上提供所有测量模式控制，无需修改打字机键盘中产生的空间控制信息。
