Today in 1913, US Patent 1051554 A was issued, an invention of Roady A. Champion, for his “Beer Faucet.” There’s no Abstract, although in the description it includes this summary:

My invention relates to faucets, and particularly to that class of faucets whereby air is forced into the upper portion of the barrel or cask containing the liquid to be delivered so as to force the liquid out through the faucet.

The primary object of my invention is to provide a very simple, cheap, and effective device of, this character, easily operated, easily’ repaired, having few parts and not liable to get out of order.

A further object is to improve the construction of the valve used in the air compressing pump whereby to prevent any out let of the beer into the pump upon the up stroke of the piston.
