Today in 1899, US Patent 635925 A was issued, an invention of William J Gindele, for his “Machine For Preparing Finings.” There’s no Abstract, although in the description it includes these claims:

My invention relates to a machine for preparing that form of gelatin which is known as finings and which is extensively employed for clarifying beer and other beverages; and the object of my invention is to provide a simple, efficient, and inexpensive machine by means of which finings may be prepared by a simple and direct process and without the employment of the heavy manual labor now ordinarily required.
