About the sound
The spring hammer (manufacturer unknown) from the 1920s was originally used in a forge in Southern Westphalia for the purpose of metalworking.
It belongs to the category of power hammers and was driven by an electric motor with a belt transmission.
By use of an integrated spring, the ram hammer (the tool which hits the work piece) vertically pounds a heated work piece, which is shaped by the pressure. In this process, the ram hammer makes a quick, loud knocking sound.
In the 19th century spring hammers replaced the tilt hammers in hammer forging because of their more powerful hammering strength. The spring hammer is currently located at the Technology Museum Schleiper Hammer and is used for demonstrations.
