history
March 24, 1779 is regarded as the founding date; On this day, the three ruling Counts of Löwenstein-Wertheim issued the brothers Tobias and Johann-Heinrich Wenzel from Neulautern a letter of inheritance for the construction of an iron hammer. A hammer building was then erected about three kilometers north of Hasloch . A moat was created for the water supply, which drives overshot water wheels. Two of the previous four hammers have been preserved; a launch hammer and a tail hammer . The hammer mill's corrugated tree is an oak trunk about 9 m long and 80 to 90 cm in diameter.
With the two fully functional devices, a wide variety of forgings can be produced. Basically, however, clappers for church bells are manufactured with an unbelievable precision of ± 2 mm for an open-die forge. The rotating waterwheel drives the hammer handle of the throwing hammer upwards via five cams on the corrugated tree . After the cams slip through, the bear falls down under its own weight of 170 kg and deforms the iron lying on the anvil. This process is repeated with each cam. Above the hammer handle is the so-called bouncer, which prevents it from being thrown up too far and amplifies the blow through its spring action.
The tail hammer is a smaller hammer with a bear weight of 135 kg. In this case, the cams press on the tail of the hammer handle and thereby lift the hammer handle. The cast iron comb ring on the corrugated tree has 14 wedged cams that cause the hammer to strike quickly. Around 40,000 to 50,000 plowshares were forged annually with this hammer.
Two other hammers used to be operated on a common corrugated tree, on these picks and picks were forged.
