Abstract
A mechanical puzzle has a three by three array four gear units at the corners and five split gears. Opposed faces of the gear units and split gears are visible through a transparent casing and apertures in the chassis. The gear units are selectively connected to the split gear halves by axially setting four selector gears by finger pressure on their stubs. Clock faces are marked round the apertures and the puzzle consists in turning the gear units by finger pressure and setting the selector gears so that pointers on the eighteen exposed faces tell the same time.
