Model of a Spoon Dredger

anonymous, 1627

Scoop dredger, model, c. 1800, after a design of 1627. Silting was a major problem in Dutch harbours, especially after 1600 as ships became larger and draughts deeper. To keep the harbours accessible numerous inventions were proposed in the 17th century. One example is this scoop dredger. The twelve 'scoops' were each operated by one man using the hoists on the raised deck. The silt was dumped in the two barges.

  • Description

    Model van een lepelbaggeraar op een grondplank, in zeer slechte staat en incompleet. Het middenschip heeft zes lieren op een verhoogd dek, die alle met de hand bediend worden en waarvan de kabels met ieder eind aan een lepel bevestigd zijn, zodat de ene lepel daalt als de andere opgehaald wordt.

Explanatory note

  • De twaalf lepels worden ieder door één man gehanteerd vanaf een der twee vlotten: hij duwt de lepel in de modder en leegt hem daarna in een van de twee modderschuiten, die beide voorzien zijn van een strijkbare mast. Aan de andere zijde van het middenschip liggen twee kleinere schuitjes, die vermoedelijk dienen om wat ballast te bergen om het schip tijdens het trekken van de bagger in evenwicht te houden. Deze baggeraar is ongetwijfeld het in 1627 gepatenteerde ontwerp van Dominicus van Wesel van de graafmachine voor kanalen onder water. Het graven van kanalen nog vóór de drooglegging was een vernieuwing. Volgens de inventaris stelt dit model ook de baggeraar die gebruikt werd in de haven van Hellevoetsluis voor, maar dit is onwaarschijnlijk.

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.
