Patent ID: 7352655

Claim:
A mechanical clock arrangement, comprising: a linkage apparatus configured to rotatingly drive at least one of an hour hand and a minute hand of a mechanical clock including a gear coupled to and configured to rotate along with at least one of the minute hand and the hour hand; a sensing device configured to sense a time of day displayed by the mechanical clock, said sensing device including a potentiometer coupled to said gear such that an output resistance of said potentiometer is dependent upon a rotational position of said gear, said potentiometer including an arcuate resistive element and a first electrical contact slidingly engaged with said resistive element, one of said resistive element and said contact being configured to rotate along with said gear; a source of an actual time of day; and a control device in communication with both said sensing device and said source of an actual time of day, said control device being configured to actuate said linkage apparatus to thereby cause the time of day displayed by the mechanical clock to correspond to the actual time of day.
