Model van een lepelbaggeraar

anoniem, 1627

Lepelbaggeraar, model, ca. 1800, naar een ontwerp uit 1627. Dichtslibbing van de Nederlandse zeehavens zorgde voor problemen, vooral toen omstreeks 1600 de diepgang van de schepen toenam. Om de havens toegankelijk te houden, werd in de 17de eeuw een groot aantal uitvindingen gedaan. De lepelbaggeraar is daar een voorbeeld van. De twaalf 'lepels' worden ieder door één man bediend door middel van de lieren op het verhoogde dek. De geschepte modder werd in een van de twee modderschuiten geleegd.

Model of a Spoon Dredger

Entry

Model of a spoon dredger, mounted on a base.

The pontoon has six winches on an elevated deck, each worked by hand. The cable of every individual drum has each end connected to a spoon, so that while one spoon rises, the other is lowered. After every stroke the rotation is reversed. Each of the twelve spoons is manoeuvred by a man standing on one of two floats. The man pushes the spoon into the mud, and after it has been lifted he unloads it into one of the two sailing mud barges, which have a mast that can be lowered. At the other side of the pontoon two small boats are secured, probably carrying ballast as a counterweight against the pull of the dredger.

The model was bought by the Department of the Navy, together with models NG-MC-1087 and NG-MC-1091, from the collection of J. Schouten in Dordrecht in 1861. This dredger is the one patented by Dominicus van Wesel in 1627 and was designed for cutting channels under water. The cutting of polder canals before the marsh had been drained, as is done today, may have been a novel feature of the invention. According to the inventory this dredger was used in the harbour of Hellevoetsluis at the end of the eighteenth and the beginning of the nineteenth century.2J.M.
