The ahe hammer

The Ahe-Hammer is a listed building in Herscheid , a municipality in the Märkisches Kreis ( North Rhine-Westphalia ). The building stands in the valley of the Black Ahe , a tributary of the Verses . The industrial monument is an old hammer forge, it belongs to the beginnings of Krupp Brüninghaus GmbH. The building is a show object and houses an operational, fully preserved hammer mill in which Osemunde iron was made. In addition to the hammer, the office, the bedroom for the forge and the old coal bunker have been preserved.

History, architecture and technology

The Brüninghaus family established a hammer mill here in the 16th century. The family mined and smelted ore in the area. The Reidemeister Peter Wilhelm Wigginhaus, Caspar Rentrop and Peter Wilhelm Brüninghaus were named in a register from 1733 as the owners of the Osemundhämmer. One note says it was built ages ago . Another directory from 1767 listed the labor required for production: two blacksmiths, a hammer goose and an apprentice boy. The hammer in its current form was built in 1884 and remained in operation until 1941. The pig iron was heated in the hearth fires and then worked with two tail hammers . In order to make it more pliable, the carbon was removed from the pig iron, which made the manufacture of wire goods easier.

The building, which stands on an irregular floor plan, was made of greywacke, and the gables are half-timbered. The roof is flat and low. The building is marked with the year "1843" and was mentioned in 1884. There is evidence of a hammer here since 1562. The water from the Ahe was stored in a hammer pond and powered the hammers. The water fell on two overshot water wheels about three meters in diameter. A gearbox drives the hammer axle, which is an oak trunk that is almost seven meters long and almost one meter in diameter. The trunk is supported by two iron cams in the reed. Two hammers are used in the forge, one weighs 160 kg, the other 90 kg, they consist of the hammer aid (the trunk) and the sleeve, which is pointed on both sides. The hammer heads are movably mounted between the two plate irons. Under each hammer there is a steel anvil, which is anchored in the ground on the so-called scabotte. The water wheel is set in motion by pulling the rubble on the flood box, and iron teeth, which sit in a wreath on the hammer axis, hit the helper from above and throw the hammer downwards. Due to the movable mounting, the hammer lifts and the hammer hits the workpiece with great force. A second wheel moves a piston up and down via a crank and thus provides the necessary wind for the forge fire.

Change of ownership

The Foundation for the Preservation of Industrial Monuments and History has been the owner of the facility since January 1, 2013 . Thyssen-Krupp AG, which operated a spring factory in Werdohl until 2011, handed the monument over to the foundation. After extensive renovation measures in 2014/15, the Ahe-Hammer is to be regularly opened for inspection from spring summer 2016.
