Today in 1891, US Patent 456872 A was issued, an invention of Frederick W. Wiesebrock, for his “Process of Manufacturing Malt.” There’s no Abstract, although in the description it includes these claims:

It is the purpose of my invention to provide a novel process for the manufacture of malt to be used in the production of fermented liquors, said process being of such a character that it may be practiced at all seasons of the year. It is my purpose, also, to materially cheapen the production of malt, to render the same independent of skilled labor, and to produce more uniform and better results than have been attainable heretofore.
