Today in 1882, US Patent 254120 A was issued, an invention of Patrick J. Darcy, for his “Beer-Cooler.” There’s no Abstract, but the description states that his “improvement relates to a device for cooling beer as it is drawn from the cask, by which it is cooled as it is used, instead of being obliged to cool the cask, and thereby diminish the head or pressure, besides the waste of ice in cooling through the wood.”
