Today in 1889, US Patent 401406 A was issued, an invention of James Amasa Bigelow, for his “Construction Of Beer Engines.” There’s no Abstract, but the description states the following. “My invention relates to apparatus for drawing beer or other liquids from a receptacle in a cellar or adjacent store-room and delivering the same to other receptacles upon a bar counter; and its objects are to provide a simple and efficient apparatus of this character in which the beer or liquids may be cooled or warmed, as desired, and in which also several kinds of beer may be mixed before delivery, and which apparatus may be readily put in order by an unskilled person should any oi` its parts become disarranged during its operation.”
