Today in 1901, US Patent 680836 A was issued, an invention of Joseph J. Danks, for his “Apparatus For Cleansing Faucets and Their Connections.” There’s no Abstract, although in the description it includes these claims:
I have invented certain new and f useful Improvements in Apparatus for Cleaning the viscous deposits and other impurities which collect in beer-dispensing faucets and their pipe or hose connections leading from the kegs or barrels from which the beer is drawn. Its main objects are to facilitate changing the connections for cleansing the dispensing apparatus and for drawing beer or other liquid to be dispensed, to save time, and to avoid waste both of the beer or liquid to be dispensed and of the cleansing materials.
