Model of Steering Gear, Truss model of the port half of a stern above the water line, which demonstrates the steering. The stern has an elliptical fence and three decks, all marked with their web, the upper deck is open. It has a large cross-shaped screw sleeve between the stern and the stern. The drum of the steering wheel is on the upper deck just in front of the propeller shaft. The steering system, which runs just below the upper deck, is a mixture of Rapson slide and slider carriage. The lower rudder pin, which is moved by the control device, is bent to be able to move in the port-side space of the screw sleeve, it is not directly connected to the rudder king, but turns on its own axis and the movement is transferred to the rudder king with two hinges. Between rails, which are arranged between the propeller tube and the ship's wall, a plate goes back and forth with a bracket loosely around the stem, driven by the handle that passes over two discs on top of this plate. The play in the bracket allows the stem to follow the movement of the plate without being hindered in the arc movement that he describes. The tension of the handlebar can be adjusted with a turnbuckle. 1:20 scale, Adolf duke of Nassau (ship), Adriaan Rosel, Rijkswerf (Willemsoord), 1867 - 1868, wood (plant material), brass (alloy), iron (metal), rope, model: h 50 cm × w 54.1 cm × d 40 cm packaging capsule: h 55 cm × w 58.5 cm × d 44.5 cm
