Picture may follow soon or never ... it seems we broke a Project Gutenburg (humourless) rule. Sorry guys.
I think this is an early patented fog bailer. I found the description very confusing, but I think the drawing in the upper right shows the opening (c) where a vacuum is created to suck in the fog laden air. Drawing A shows how the water is released when the flap rises. See the little outlet (s) that the water passes through. This is where Bob Godfrey would collect his fog juice. I have no idea what the calibrated contraptions are for.
Anyway, this is much earlier than the boat-mounted versions described by Gordon Weatherby.
Now does anyone have a line on a manufacturer.
