Today in 1883, US Patent 287357 A was issued, an invention of William A. Babcock, for his beer “Faucet.” There’s no Abstract, although in the description it includes these claims:

My invent on applies more especially to} faucets for the dispensing of beer or other beverages kept on draft in bars or similar; places; and the chief object of my improvement is to keep the liquid in the faucet free from any metallic taint or flavor, and also to preserve it in a cool condition, ready to be discharged into the next glass in a perfectly palatable state.
