Abstract
A balanced hands clock. The clock utilizes a single movement, which movement may be located in the minute hand. A gear drive mechanism provides leverage from said movement via a first pivot shaft to drive the hour hand. The clock is mounted in a base for time indicating movement. Covers may be provided to hide the single movement and the gear mechanism so that no visible drive configuration is visible to an observer.

A clock, said clock comprising:
- a body;
- a first pivot shaft, said first pivot shaft rotatably extending from said body;
- a minute hand, said minute hand secured to said first pivot shaft, said minute hand further comprising a single clock movement, and wherein said minute hand is operably balanced about said first pivot shaft;
- an hour hand, said hour hand operably balanced about said first pivot shaft;
- said hour hand moveable with respect to said minute hand and operable by said minute hand through a drive mechanism so that said minute hand rotatably operates said hour hand about said first pivot shaft.
A clock, said clock comprising:

- a minute hand, said minute hand secured to said first pivot shaft, said minute hand further comprising a single clock movement, and wherein said minute hand is operably balanced about said first pivot shaft;
- an hour hand, said hour hand operably balanced about said first pivot shaft, said hour hand moveable with respect to said minute hand and operable by said minute hand through a drive mechanism so that said minute hand rotatably operates said hour hand about said first pivot shaft, said drive mechanism comprising
- a baseplate,
- a second pivot shaft fixed to said baseplate,
- a first gear, said first gear rotabably secured for movement about said second pivot shaft, said first gear further comprising first gear mass, said first gear mass provided with said first gear at a selected first gear orientation position on said first gear, and wherein said first gear mass biases said selected first gear orientation position downward in the direction of gravity forces,
- a second gear, said second gear rotating in concert with said first pivot shaft,
- said first gear and said second gear each comprising toothed gears wherein a gear ratio R, being the number of teeth in said first gear divided by the number of teeth in said second gear, is eleven (11).
