Patent No. 436498A: Apparatus For Brewing

September 16, 2016 By Jay Brooks

patent-logo
Today in 1890, US Patent 436498 A was issued, an invention of Carl Hafner, for his “Apparatus For Brewing.” There’s no Abstract, although in the description it includes these claims:

My invention relates to an improved apparatus for use in the process of making beer.

In the usual process of boiling beer or wort with hops the essential oils, aroma, and volatile oils escape and are wasted or are condensed and passed back into the brew-kettle during the boiling process; but as the essential oils, aroma, etc., vaporize and escape when the hot liquid remains at a temperature of about Reaumur, and as it is necessary after boiling the wort with the hops a certain time to allow the boiling liquid to cool oft in the open air, it will thus be seen that these volatile matters will still escape.

The object of my invention is to provide an improved apparatus for use in the process of manufacturing beer, whereby the essential oils, volatile matters, etc., are saved and afterward added to the beer, and whereby a great saving is made in hops. These objects are accomplished by and my invention consists in certain novel features of construction and combinations of parts, more fully described hereinafter, and particularly pointed out in the claim.
