Today in 1885, US Patent 330184 A was issued, an invention of Conrad Zimmer, for his “Process of Brewing Beer.” There’s no Abstract, although in the description it includes this summary:

The invention consists in a process of brewing beer which consists in subjecting finely ground malt from which the hulls and germs have been removed and water to the saccharification temperature, then boiling the mash a sufficient length of time to coagulate the albuminous substances and render the same insoluble, then separating the clear wort from the insoluble substances, then directly passing the mash into a centrifugal machine for separating the clear wort from the insoluble substance by centrifugal-force, and finally conducting the clear wort to a hop-kettle and boiling it therein.
