August 12, 2016 By Jay Brooks

Today in 1884, US Patent RE10509 E was issued, an invention of Frederick O. Kunz, for his “Mash Cooler.” There’s no Abstract, although in the description it includes these claims:

This invention relates to an apparatus for cooling mash to the fermentation temperature, which is simple in construction, effective in operation, and capable of being thoroughly cleaned with facility. The apparatus comprises a vertical column or chamber, which is traversed by a series of water conducting pipes, and is provided with detachable outer walls and doors for gaining access into the interior of the column and the tubes, for cleaning and other purposes. The water-tubes extend through the shell of the vertical column and lead into small non-communicating chambers formed between the shell of the cooler and the outer walls. The object of these chambers is to cause the water circulating through the tubes in an upward 0 direction to take a circuitous or zigzag course and flow out at the top of the cooler. The mash to be cooled flows into the cooler at the top thereof, and is strained and thrown down over the pipes in the form of a shower, and it makes its exit at the bottom of the cooler and passes through a vertical stand-pipe and escapes at the top of the latter, being then of a temperature suitable for immediate fermentation in the customary fermenters.
