Model of a Pair of Hydraulic Forge Bellows, Model of a hydraulic bellows on a floorboard. It consists of a barrel that is hung horizontally in two forks and can be turned a quarter circle around its axis by means of a lever. The space inside is transformed by a tube in the axis direction into an endless circle, which in turn is made finite by a partition placed in the longitudinal direction between the outer and inner walls on top of the tube. On one side there is an incoming valve with chamois leather valve on either side of this partition, on the other side outgoing valves to which a ventilation pipe is connected. When half the container is filled with water, the space that remains for air is divided into two compartments: by turning the container back and forth, they become alternately larger and smaller, because the water surface remains horizontal. This is how the airflow is created. The ventilation pipe is bent so that the end is flush with the axis of rotation, and connects to a fixed pipe in a wall behind the bellows. A double water tank is fitted in the floor between the vessel and the wall: one part is closed off at the top and connected to the other by a groove at the bottom of the partition, the sealed part is connected to the ventilation pipe with a vertical pipe., Rijkswerf Rotterdam, 1818 and/or c. 1800 - c. 1815, wood (plant material), brass (alloy), chamois (animal material), h 17 cm × w 18 cm × d 16.5 cm
