ABSTRACT:
A simplified gear drive mechanism for an indicating device such as a clock. The output shaft of the indicator's drive motor carries an eccentric which orbits a multiple gear tooth orbiting gear. One gear on the orbiting gear engages a stationary ring gear having a different number of teeth while another gear on the orbiting gear engages an output ring gear having a different number of teeth. This output ring gear may, for example, be employed to drive the minute hand of a clock. To provide multiple indicators such as required in a clock, a second orbital gear train is provided having an eccentric on the output gear of the first gear train for the purpose of orbiting an orbiting gear in the second gear train. An output ring gear in the second orbiting gear train is employed to drive the hour hand of the clock. In another embodiment of the present invention, a similar orbiting gearing arrangement is employed for driving a digital indicator, such as a digital clock.
