发明名称 Device for adjustment of electrical clocks
摘要 A device for adjustment of an electrical clock with a clockwork train, the latter having an hour pointer driven via an hour gearwheel and via an hour intermediate wheel, a minutes pointer which is driven by means of a minutes gearwheel (the hour intermediate wheel being coupled in clock drive operation with the minutes gearwheel) and a minutes intermediate wheel, as well as having additional gearwheels with a first transmission ratio, the minutes intermediate wheel being coupled with a motor via the additional gearwheels. The minutes gearwheel is decouplable from the minutes intermediate wheel for the coarse adjustment of the minutes pointer and, by means of at least one additional gearwheel with a second transmission ratio which is more direct than the first transmission ratio, the minutes gearwheel is coupleable with the motor.
