Today in 1940, US Patent 2203130 A was issued, an invention of Patrick J. Costello, for his “Beer Energizer.” There’s no Abstract, though the description in the application states that the “object of my invention is to provide a device for drawing beer in its normal stage without applying extra pressure or force, whereby to create a line creamy foam.” I’m not sure what about that “energizes” the beer, but it’s certainly a catchy name.
