(Paternoster) waterlift Vera's pomp

Amsterdam Possibly Jochem Cats, 1775 - 1799

This instrument demonstrates that water can be raised by a rope (or chain) alone. It is only possible when the rope moves very fast. In this apparatus, using a large driving wheel makes this fast movement possible. Water ‘stuck’ (cohesion) to the rope is thus raised very fast. In 1794 a pump like this was described by the English physicist George Adams. He called the instrument Vera’s pump. The pump described by Adams could pump up as much as 9 gallons of water (1 gallon = 4.54609 litre) a minute.
