Today in 1874, US Patent 154367 A was issued, an invention of Lemen J. Birgler, for his “Improvement in Faucets.” There’s no Abstract, although in the description it includes these claims:

My invention relates to a faucet with vent attachment, for drawing of fermented or other liquors from the barrel or keg without the aid of a vent in the bung or other part of the barrel, the vent working automatically in connection with the opening or closing of the faucet, and forming a very convenient, regularly-acting, and independent attachment for keeping the liquids .fresh and nice for any length of time.

The invention consists of a faucet with guide-tube and sliding vent-tube, which is provided at the inner end with a flexible rubber tube and floating valve, and with a second valve at the outer end, through which air is drawn into the barrel when the faucet is opened.
