ABSTRACT:
The tabulator blade rack consists of a pivotally and axially movable rod. Depressing the desired decimal tabulation key frees the carriage from the escapement for movement in the typing direction, raises the corresponding tabulator stop, and rotates the tabulator rack and the blades thereon. Operation of the set and clear key sets a blade; the carriage moves, striking a projection on the set blade, thereby shifting the rack to the right until a stop thereon hits the raised tabulator stop, stopping the carriage at the corresponding position. When the rack stop hits the tabulator stop, the consequent movement of a rod that mounts the latter causes the raised tabulator stop to be lowered, the return of the rack, both longitudinally and rotationally, to its rest position, and the carriage to be reengaged with the escapement at the chosen tabulating position.
