ABSTRACT:
A mechanical device to be easily placed and removed over the margin rod of a key operated machine and having motion transfer levers which mechanically couple certain of its keys to other corresponding keys of the machine. The device is suitable for providing automatic carriage return after the space bar is activated within the margin zone, thus providing for improved alignment of the right margin, compression of the typed information, and increased typing speed.
