Today in 1934, US Patent 1964836 A was issued, an invention of Abram W. Wheaton, for his beer “Faucet.” There’s no Abstract, although in the description it includes this summary:

This invention relates, generally, to faucets and the invention has reference, more particularly, to an improved faucet, which while adapted for general purposes, is especially intended for use as a beer faucet.

The principal object of the present invention is to provide an improved faucet having a novel construction of gas separating bafile incorporated therein, said bafile serving to liberate a considerable portion of the carbon dioxide and other gas content of the beer as the same flows through the faucet, thereby greatly reducing the amount of foam ordinarily produced when drawing beer and preventing considerable waste which usually occurs when using ordinary beer faucets.

Another object of the present invention lies in the provision of an improved faucet having a novel sheet metal gas separating baffle of simple, rugged construction, the said baflle being so constructed as to enable the same to be readily inserted into or removed from the faucet and having means to insure its proper installation in the faucet.
