Today in 1936, US Patent 2039564 A was issued, an invention of Elmer H. Smith, for his “Beer Dispensing Apparatus.” There’s no Abstract, but in the description it states that his “invention relates to new and useful improvements in beer dispensing apparatus, and more particularly to a beer dispensing faucet having means embodied in the construction thereof, whereby the beer, regardless of the pressure on, the beer at its source, may be dispensed into, a glass or suitable container without excessive foam.”
