Today in 1897, US Patent 580303 A was issued, an invention of Henry E. Bailey, for his “Apparatus For Cleaning Pipes.” There’s no Abstract, although in the description it includes this summary:
In using beer and other malted liquors there is found a tendency to the formation of slime and other offensive matter that is deposited therein by the liquid from which it emanates. This deposition will soon produce a cloudy appearance and objectionable taste in the liquid that flows through the pipe.
The object of my invention is to provide an apparatus that will chemically dissolve the slime and other depositions in the pipe and then, by a flow of clear water which passes through the apparatus,thoroughly cleanse the pipe of all improper matter and restore it to a condition of purity and cleanliness.
