Today in 1934, US Patent 1957083 A was issued, an invention of Frank Schneible, for his “Apparatus for Dispensing Beer and the Like.” There’s no Abstract, but the description tries to explain it, though I’ll leave it up to you if it makes a great deal of sense as described:
In another application oF the present applicant for Letters Patent of the United States for a beverage cooling apparatus, Serial No. 674,823 filed June 8, 1933, there was shown and described an apparatus particularly designed to meet the peculiar conditions which arise in the dispensing of fermented malt liquors, such as beer, in the dispensing of which conditions or” temperature and pressure must be regulated carefully. ln the apparatus so shown and described provision was for final regulation of temperature and flow in a final cooling chamber in which the beer passes on its way to the dispensing faucet through a coil or a container surrounded by a cooling medium, such as a cold brine. It has been found that some advantages reside in the use of a container, that is, as distinguished from a coil, a vessel in which there can be held a more substantial volume of the beverage to be dispensed than can be held in a cooling coil or pipe. it has therefore been the object of the present invention to devise a beverage cooling container in which it shall be possible to cool and store for a considerable period or” time a quantity of beer on its way to the dispensing faucet without any deleterious effects on the beer and by the operation of which flow or” beer can be regulated to meet the requirements of consumption and temperature. In accordance with the invention there is provided an outer shell or vessel, preferably of metal, which can be opened readily for inspection and cleaning, and an inner vessel, preferably of porcelain or glass, into which the beer is delivered from the keg or barrel, which is the source of supply, through a narrow space which separates the inner container from the outer shell and in which the beer, on its way to the inner container, is cooled through contact with the inner wall of the outer shell or vessel which is itself surrounded by the brine or other cooling medium employed. The inner container is supported within the outer shell in such manner that it may rise or fall with variation in its contents and in rising or falling may regulate the inflow of beer from the source of supply in accordance with the demands of consumption.
