Today in 1936, US Patent 2028283 A was issued, an invention of Jules Howard and Sanford E. Richeson, for their “Foam Controlling Beer Faucet.” There’s no Abstract, but the description explains that the “invention relates to beer and like taps or valves for drawing off foamy liquid from a cooler or other container.” It was designed “to prevent loss of the liquid incident to foaming in the glass after standing for some time in the cooler or container, and at the same time to regulate the depth of the head or cap of foam at the top of the glass.”
