Historical information
Portable foghorn with workings in wooden box. Foghorn sound is made by turning the handle on the outside of the box. The rotational movement pumps bellows inside the box, forcing air across a fine reed, similar to a clarinet reed, which makes the sound. The sound is amplified by the round horn inserted into one end of the box. Different warning signals are made by turning the handle at different speeds and by stopping and starting the handle.
