Today in 1920, US Patent 1328079 A was issued, an invention of Charles B. Davis, for his “Process of Mashing.” There’s no Abstract, and there’s not much of an introduction or overview, he just dives right into a detailed explanation of his invention. It’s curious that the patent office approved it three days before Prohibition took effect in 1920, although he first applied for the patent in 1915. Davis probably didn’t make too many sales over the subsequent thirteen years.
