Today in 1890, US Patent 426965 A was issued, an invention of Phillip Seibel, for his “Beer-Filtering Apparatus.” There’s no Abstract, although in the description it includes this summary:
This filtering apparatus is intended especially for beer or other liquids liable to foam, and has means for the removal of the foam into a settling-chamber, from which the liquid is withdrawn as it subsides. The apparatus is composed of two or more similar filters connected with the same system of circulating pipes.
