Hydrant Thawing Device
After considerable study and experiment the Ross Hydrant Thawing Device has been perfected and is now placed on the market by the American-LaFrance Fire Engine Company of Elmira, N. Y. The Ross Thawing Device was invented by Louis S. Ross of Newton, Mass., and is manufactured by the American-LaFrance Fire Engine Company. Mr. Ross has long been an expert on steam engineering and at one time held the world’s record for the fastest mile ever travelled. This record was made at Ormond Beach, Florida, in a steam driven car of Mr. Ross’ own design.
The thawing device may be described briefly as a steam coil surrounded by a jacket tank, which is filled with water for pumping into the steam soil. By means of a hand operated pump water can be forced from the tank into the coils and by regulating this feed either “wet” or “superheated” steam can be secured at the nozzle. Water is fed continuously into the coil, being converted into steam exactly as is the case when a drop of water falls on a red hot stove. The heat is produced from a standard Presto-lite style “B” tank carried with the outfit. The steam is led through fifteen feet of flexible metallic hose with a braided steel jacket covered for over half its length with asbestos, which in turn is protected by a canvas cover, and the whole wrapping bound with wire.
The entire thawing device weighs 135 pounds, is 28 inches across the base, 12 inches wide, and 25 inches high.
