Today in 1912, US Patent 1021669 A was issued, an invention of William W. Frisholm, for his “Beer-Tapper.” There’s no Abstract, but the description states that his “invention is an improvement in beer tappers, and consists in certain novel constructions, and combinations of parts, hereinafter described and claimed. Sometimes the language in these is just wonderful, case in point:

The object of the invention is to provide an improved device for tapping beer and other effervescing liquids which will permit the entering of the device into the keg or other receptacle without waste, and which, while permitting the free egress of the liquid, will also permit the entrance of air under pressure to force out the liquid.
