Today in 1863, US Patent 40200 A was issued, an invention of Henry Steubing, for his “Improved Apparatus For Cooling Beer or Other Liquids.” There’s no Abstract, although in the description it includes these claims:
The said apparatus is used in the following manner: Cold water or iced water is introduced into the space d from a reservoir, until the space d is filled with it and during the whole time of cooling. Then the ale, beer, or other liquid to be cooled is admitted into the hollow cylinder c steadily and continuously, when the same Will overflow into the space formed by the flange e, and will 110W down through the holes n n’ n on the outer mantel, a, into the space formed by the lower flange, j’, after which it flows out of the apparatus through the pipe i. Thus it will be seen that a certain quantity of iced water or cold water cools the ale, beer, or other liquid, rst by its contact on the inside b of the cooler, and then by its contact on the outside c of said cooler, thereby effecting `a great saving of the cooling material.
