The Third Wheel

Reference no 210

The Third Wheel (210) pinion is driven by the Second Wheel (201). The Third Wheel in turn drives the Fourth Wheel (224) pinion.

The Wheel Train starts to the left with the Barrel (182) which drives the Center Wheel (201) pinion. The rotation speed is further increased via the Third Wheel (210) to the Fourth Wheel (224), which makes one revolution per minute and has the second hand attached to its arbor. Finally the Fourth Wheel engages the Escape Wheel (230) pinion.
