Model of a Double Capstan, Model of a double capstan in a wooden frame that represents two decks. Both capstans are for twelve wind trees and have six molars. The lower drum has eight catches in the foot to prevent it from running back. The drums can be used in four ways: blocked, separate, coupled, and combined so that the upper drives the lower with delay. The combinations are obtained with catches in the base of the lower drum, with which the gear consisting of sun and planetary wheels, placed under the lower deck between the beams, can be put into operation, and by coupling or disconnectin
