Model of an Oscillating Pump, Model of a pendulum pump, on a tripod. It is a double-acting pump with two square pump tubes, which are connected below with a single, round pump tube. The pump pistons consist of a metal plate that is placed diagonally in the pump tube and on which two triangular, leather-covered valves, they are weighted with lead. At the bottom of the square pump tubes are placed pump buckets of the same design. The pistons are connected to each other by a chain that runs over a wheel in the pump bowl, on the outside a pendulum is attached to the axle of the wheel, and above a yoke for a chain or rope, with this yoke the pendulum movement is started, whereby the pistons are each in turn pulled up and down., anonymous, 1821, wood (plant material), brass (alloy), iron (metal), leather, model: h 85.3 cm × w 41 cm × d 34.5 cm packaging capsule: h 91 cm × w 44.5 cm × d 40 cm
