Abstract: An encoding keyboard constructed like that disclosed in U.S. Pat. No. 3,086,635, entitled ''''Keylever Storage Mechanism,'''' issued Apr. 23, 1963, to Leon E. Palmer is provided with a novel dual keylever construction that properly time-sequences up and down shift code entries with respect to character entries. The stroke storage provided in the keyboard of U.S. Pat. No. 3,086,635 is expanded to provide storage for two characters, when necessary, to accommodate the characteristically rapid and arhythmic, three-stroke sequence, ''''upshift-print-downshift.

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.
