Koolsmoke, an American pipe, bowls looking much like Falcon, except these only have a single thread, not the 4 start thread of the Falcon. Confusingly there seem to be boxes around containing Koolsmoke pipe and spare bowls, but labelled Rogers Drymatic as per lower image. The nut in the cup can be adjusted to alter the space between the bowl and pipe to suit the smoker or the actual bowl in use 29 Nov 1955 US patent # D176221 Without the adjustable nut and 2,760-496 with the nut (also comes as Dri-Smoke) Inventor Ben Lieber, Brooklyn New York assignor Aply-Tech Products |
