Today in 1872, US Patent 123390 A was issued, an invention of Charles Geenen, for his “Improvement in Beer and Water Coolers.” There’s no Abstract, although in the description it includes this summary:

My device relates to that class of coolers or refrigerators which have an interior ice-receptacle, an outer inclosed chamber, in which is placed some non-conducting material or substance, and an intermediate chamber or chambers, in which, and through which, the beer is made to pass directly from the barrel or vessel in which the beer is contained. The object which I have in viewing my device is to furnish a cooler or refrigerator which Shall be portable, cheap, and conveniently handled or moved from one place or position to another in a store or other room, wherever it may be required to use it, and, at the same time, easily attached, by means of pipes, flexible or otherwise, to the barrel or vessel containing the beer which it is desired to cool; but my improvement will be more clearly understood by reference to the annexed drawing, whereon all that I claim as pertaining thereto is very clearly shown, and on Which- Y Figure l represents a perspective view of the cooler as when complete and ready for use. Fig. 2 is a vertical section of the same.
