Hello lighthouse community,
I am a sound engineer by trade. An architect I've recently worked with is now working on plans for restoring an unspecified lighthouse, and asked me if I had any knowledge of the Daboll Fog Trumpet. I've found that it is a reed horn driven by compressed air, with the largest being some 17 feet long. I am seeking more specific information as far as pictures, diagrams, specifications, etc. which I can send to the architect. There's some possibility that they may try to re-create one.

While fog signals are a passion of mine, I have yet to come across any plans or specifications for the Daboll trumpet.

The patent can be found and downloaded at:
