Today in 1902, US Patent 703206 A was issued, an invention of Patrick H. Keefe, for his “Beer-Tapping Apparatus.” There’s no Abstract, although in the description it includes this summary:
This invention relates to certain new and useful improvements in beer-tapping apparatus wherein an air-supply is in communication with the cask or barrel containing the beer or like liquid, and has for its object to provide means for furnishing a constant supply of air to the liquid, so that the latter may be drawn on through a pipe, which conducts the same to a suitable and convenient point.
