Page 10 - E, the magnetism of the electro-magnet is destroyed, and the spring f carries back the keeper, which, by means of the arm a, gives a blow to the lever b. Thus the marker m is made to depart from the uniform spiral it was describing. When the current is restored the keeper is attracted, and thus the marker m is brought back, which continues to trace its spiral as if nothing had happened. E is connected with the clock, and its marker m
