Patent No. 739595A: Cooling Apparatus For Liquids

September 22, 2016 By Jay Brooks

Today in 1903, US Patent 739595 A was issued, an invention of Hugo Fluegge, for his “Cooling Apparatus For Liquids.” There’s no Abstract, although in the description it includes these claims:

My invention relates to cooling apparatus for liquids; and the object of my invention is to provide an apparatus by means of which the carbonic-acid gas used in an apparatus for supplying beer or other similar liquids under gaseous pressure can at the same time be also used for the purpose of cooling `the liquid to be served out, this device therefore doing away with the necessity of cooling the liquid by means of ice, as hitherto was usually the case.

The principal feature of my cooling apparatus is the arrangement of a spiral pipe, which is securely fixed within a chamber containing water or other similar fluid. The carbonic-acid gas which flows through this spiral pipe cools the water surrounding the pipe to such an extent that it begins to freeze. Consequently the liquid to be served out, which is contained in air-tight glass cylinders and which are surrounded by the freezing water, can be cooled in this manner to any required degree.
