ABSTRACT:
A clock design incorporates both digital and analog aspects. An "hour" ball riding a vertically oriented spiral raceway is lifted in a straight line from the bottom of the outer spiral to the bottom of the inner spiral as the raceway rotates at the rate of one revolution per hour, its presence on a given spiral constituting a digital selection of the hour associated with that given spiral. A "minute" ball is fixedly mounted on the raceway periphery, its rotational orientation constituting an analog selection of the minutes.
