Abstract
An astable multivibrator, driven by a solar battery or other long-term current supply, pulses an electromagnetic stepping drive for intermittently winding up a coil spring which powers a mechanical clockwork. The spring, connected to its stepping drive via a one-way coupling permitting manual rewinding, has one end secured to a leadscrew and has its other end tied to a nut thereon so that the degree of unwinding is indicated by the axial position of the nut on the lead screw. When the spring has been tightened to a predetermined extent, the nut trips an electric switch or a lever to prevent overwinding by disconnecting the multivibrator, arresting the stepping drive or decoupling that drive from its load.
