ABSTRACT:
Stepped-down counting mechanism with number wheels drawn on a locking shaft, with a control disc and with a slotted link. The number wheels and the control disc are moved by a ratchet shaft which is located in the interior of the locking shaft and to which are articulated pawls each acting on one pair of wheels. The switching mode with single or multiple stepping-down can be selected by adjusting the slotted link. The control disc is moved by means of an idle-stroke pawl subjected to the action of the slotted link and, independently thereof, by means of an advancing pawl acting between the control disc and the units wheel.
