Entry
Wooden frame model of a double-keeled caisson for a dry dock.
One side of the caisson is finished, the other side is open. The caisson has three decks and is divided into two compartments lengthwise. On the closed side there are two small floodgates, the valves are missing. There are sockets for one pump only on either side. This model is very similar to model NG-MC-991 and it fits in to its bed.
This caisson was invented by the French engineer Antoine Groignard (1727-1799) and was used for the first time at the dry dock in Toulon in 1778.1 Although caissons were by no means a novelty at the time, Groignard’s design introduced some major improvements.2
A similar model is in the collection of the Teylers Museum in Haarlem.3
Scale unknown.
