All of Leonardo’s machines, from the simplest to the most complex, consist of mechanical elements that make it possible, when connected to one another, to transmit and transform motion.
The mechanism on display represents one of the simplest solutions for converting alternating motion into continuous motion. A driving lever is moved back and forth, actuating two parallel rods, making them move simultaneously, first in one direction and then in the opposite. The two rods, equipped with teeth cut in opposite directions, mesh alternately with the wheel placed at the center of the mechanism.
The wheel, as Leonardo says, will therefore always move “in one single direction,” driven by the alternating action of the two rods.
