Model of a Double Capstan, Model of a double capstan in a wooden frame with three levels. Both drums have holes for ten wind trees and have no molars. The upper drum can be opened in four places to show the gear consisting of horizontal and a pair of inclined gear wheels, which transfers the movement of the upper drum in a ratio of 11/1 in the reverse direction to the lower drum. There is a keyhole just below the head of the upper drum, but the key is missing, so its function is not outdated. The lower drum has a toothed circle on the head with a pawl hanging on the ceiling, to prevent it from falling back. Shafts for disks are mounted in the sides of the frame, probably for demonstration ropes. Scale 1: 5 (estimate)., anonymous, Netherlands, c. 1860, wood (plant material), brass (alloy), model: h 68 cm × w 88.7 cm × d 25.5 cm packaging capsule: h 75.5 cm × w 95 cm × d 30.2 cm
