ABSTRACT:
An electrical circuit is employed for receiving current from a small battery and converting it into a large intermittent force which will move a heavy load. In the example shown the load is a clock spring which is wound in small increments by the large intermittent force. A capacitor is charged by the battery. The battery and capacitor, therefore, temporarily have a higher output current than the battery alone. The output of the battery and capacitor is applied to a solenoid for attracting an armature and providing the large force. The resulting movement of the armature opens the circuit to the solenoid but the solenoid remains energized temporarily since a small capacitor is across it. When the armature returns to its normal off position it reenergizes the solenoid. The resulting on and off operation of the solenoid continues until the clock spring is fully wound. The combination of the battery and capacitor which is across the battery also operates a second load intermittently and the energization of this second load is controlled by a switch operated by the armature of the solenoid.
