Today in 1866, US Patent 57746 A was issued, an invention of Robert W. McClelland, for his “Improved Refrigerator For Liquids.” There’s no Abstract, although in the description it includes these claims:
What I claim as my invention, and seek to secure by Letters Patent, is a refrigerator for cooling ale, beer, and other liquids, arranged so that the casks may be supported upon slides E, resting upon the ways D in the upper part of the chest A, and the liquids be conducted by a flexible pipe, G, into a receiver, I, inclosed in the cooling-tube H, and then drawn for use through a faucet, M, passing through the small doors 0, said several parts being constructed and arranged substantially as set forth.
