Today in 1902, US Patent 747729 A was issued, an invention of William Koedding, for his “Automatic Filling Machine.” There’s no Abstract, although in the description it includes these claims:

My invention relates to machines for filling bottles and other receptacles with liquid, and has for its principal objects to produce a filling-machine which will operate automatically when the bottle is pressed against it in proper position to be filled, to equalize the pressure in the bottle with the pressure in the supply-pipe before the supply-pipe is opened to permit the liquid to How into the bottle, to provide for automatically stopping the flow of the liquid when the bottle is filled, and to prevent any stale liquid getting into the bottle.
