Model of a submarine, Model of a Submarine, Copper model of a submarine on a wooden stand, with a separate wooden box with tools. Drop-shaped hull with flat edge around it, on which a guard rail. The upper dome has a number of lights, a cockpit and a water-tight manhole, inside is a compartment for the mechanics and drivers, this compartment can be lifted out so that the diving tank underneath becomes visible. The propulsion is done by hand: with a crank, gear and a flywheel on either side, centrifugal pumps are driven, which push the water backwards through nozzles. The diving tank is filled by means of a large valve in the middle, while the air is fed through two valves to the upper compartment, they also serve as an overflow at the same time. There are four separate floating tanks and lead ballast in the front of the dive tank. The dive tank is emptied with two pumps, which are driven with the same cranks as for the propulsion, by pumping back the air from the upper compartment, the water is expelled through the same opening as it was allowed through. The keel, which is weighted with lead ballast, can be repelled: the vessel floats to the surface and the keel is lifted again by means of two winches. Large rectangular rudder, controlled from the inside with a horizontal steering wheel. The independently driven centrifugal pumps offer an additional control option. Vertical steering is done by shifting mobile weights inside, which run along the side with wheels on rails and are moved by means of winches and ropes. A small compass is provided for navigation. A four-armed dredge is hung at the bottom of the bow. Scale 1:10, ship model (propulsion of vehicle, ship, etc. by human power), submarine, Antoine Lipkens, 1835 - 1840, copper (metal), brass (alloy), iron (metal), glass, leather, rope, wood (plant material), h 52 cm (open) × h 39.4 cm (closed on stand) × l 80.7 cm × w 28.3 cm
