Description

De Eendracht is what the Dutch describe as an Grondzeiler. It is a tow storey smock mill on a single storey base. There is no stage, the sails reaching down almost to ground level. The mill is winded by tailpole and winch. The smock and cap are thatched. The sails are two Common sails and two Patent sails with Dekkerised leading edges. They have a span of 17 metre. The sails are carried on a wooden windshaft. The windshaft also carries the brake wheel which has 52 cogs. This drives the wallower (32 cogs) at the top of the upright shaft. At the bottom of the upright shaft is the crown wheel, which has 46 cogs drives a gearwheel with 35 cogs on the axle of the Archimedes screw. The axle of the Archimedes screw is 508 millimetre diameter. The screw is 1.34 metre diameter and 5.52 metre long. It is inclined at 20.4°. Each revolution of the screw lifts 802 litres (176.4 imp gal) of water.
