AbstractA mechanical clock is described, which operates reed relays, microswitches, silicon controlled rectifiers, and Schmitt trigger circuits to provide output pulses at intervals ranging from 1 second to 24 hours. All outputs are gated back to the 1-second timing pulses and therefore have the same basic accuracy. The mechanical accuracy is better than ±0.1 second; long-term accuracy is dependant entirely upon the accuracy of the ac power source for the drive motor.
