Figure wheels (drums) 2 are set to zero by turning shaft 1 clockwise. This also turns frame 3, secured on shaft 1, thereby disengaging the drive gears of the counter. At the same time, lever 4, having a bevelled end, disengages toothed clutch 5. Then lever 6 actuates cam 7 to set the figure drums to zero. Spring 8 returns shaft 1 and the levers mounted on it to their initial positions.
