Today in 1911, US Patent 963323 A was issued, an invention of Jonas Quigley and Oliver N. Beck, for their “Beer Tap.” There’s no Abstract, although in the description it includes this summary:

Our invention relates particularly to beer tapping means in which a tap-tube is employed in connection with a casing therefor through which air-pressure is transmitted to the liquid; and our object is to provide an improved device of very simple construction and operation, as fully described in connection with the accompanying drawing, and the novelty of which is specifically pointed out in the claim.
