Patent No. 431246A: Mash Machine

July 1, 2016 By Jay Brooks

Today in 1890, US Patent 431246 A was issued, an invention of Andrew W. Billings, for his “Mash Machine.” There’s no Abstract, although in the description it includes this summary:

My invention relates to certain improvements in the apparatus for and method of manufacturing beer set forth in Letters Patent No. 324,523, granted to me August 18, 1885; and my invention consists in combining and heating the materials forming what I term the supplemental mash, which consists of raw grain and malt mixed in proper proportions and under conditions as set forth in said patent, as fully set forth hereinafter, so as to adapt the operation to the character of the material acted upon and reduce the length of time required in making the supplemental mash, and also in certain improvements in the apparatus. In this class of apparatus, as ordinarily constructed, the stirrer blades are immovably fixed in position, or are so arranged and fitted for the one kind of mash to be made that they cannot be used for anything else than for an ordinary mash, nor can they be changed in any manner, and they fail to so agitate the mass as to maintain all parts at the same temperature and in the same condition. In the apparatus as constructed by me the blades are easily and readily changed as to number, position on the arms, their angle to the arms and each other without any danger of their working loose while in motion, thus enabling me to make either a very thick or thin mash and successfully operate with any kind of grain (malted or unmalted) or starch, maintain all parts in the same condition, obtain the largest possible percentage of extract, and to use a very much larger percentage of the raw grain.
