Patent No. 123390A: Improvement In Beer And Water Coolers

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.


Patent No. 3789622A: Ice Box For Beer Barrel

Today in 1974, US Patent 3789622 A was issued, an invention of Ralph Yanes, for his “Ice Box For Beer Barrel.” Here’s the Abstract:

An insulated barrel shape structure for housing and suspending a beer barrel in the horizontal position surrounded by ice. The rear circular cover of the device is removable for the installation and replacement of the beer barrel and surrounding ice. The circular front cover bears a circular opening for the spigot of the beer barrel. The structure provides for an air-seal between the sides and bottom of the housed beer barrel and the iced refrigerated area of the structure.


Patent No. 667478A: Hop-Drying Box

Today in 1901, US Patent 667478 A was issued, an invention of Adolf Wolf, for his “Hop-Drying Box.” There’s no Abstract, although in the description it includes this summary:

My invention relates to boxes for holding loose material, such as hops, in the process of drying the same, and has for its object to provide a construction which permits the box to be readily turned upside down without discharging the contents thereof and while leaving the top open for a thorough evaporation and escape of steam. For this purpose I provide the box with a removable top and a removable bottom, constructed and secured in a novel manner, as will be fully described hereinafter, and particularly pointed out in the appended claim.


Patent No. 3425839A: Continuous Beer Making Process Wherein The Wort And Yeast Are Separated By A Porous Partition

Today in 1969, US Patent 3425839 A was issued, an invention of Michael Alan Pinnegar, assigned to Brewing Patents Ltd., for his “Continuous Beer Making Process Wherein the Wort and Yeast Are Separated by a Porous Partition.” There’s no Abstract, although in the description it includes this summary:

A potable beer is produced by circulating a body of yeast-containing liquor on one side of a partition and maintaining a moving body of wort on the opposite side of the partition. The partition is porous and has a pore size small enough to effectively bar the passage of yeast cells, but allows the passage of the soluble constituents of the wort and the soluble products resulting from the fermentation of the wort by the yeast.

The present invention relates to the production of potable beer by the fermentation of brewers wort by yeast in a continuous fermentation process. The term continuous fermentation process is used herein to refer to a fermentation process, in which brewers Wort is introduced in a stream into a fermentation zone. The stream of wort can be introduced at either constant or varying rates and may be continuous or discontinuous in the sense of being interrupted at constant or varying intervals. However in the generally preferred procedure brewers wort is introduced into the fermentation zone at a substantially constant rate over a substantial period of time e.g. not less than five days.


Patent No. 2230905A: Beverage Cooling Apparatus

Today in 1941, US Patent 2230905 A was issued, an invention of Louis L. Popky, for his “Beverage Cooling Apparatus.” There’s no Abstract, although in the description it includes this summary:

The present invention relates to new and useful improvements in apparatus for cooling and dispensing beer and similar beverages, and has for its primary object to provide a dispensing cabinet of a portable nature in which the dispensing faucet is mounted, the faucet being connected to the keg positioned in a room remotely disposed with respect to the cabinet and providing a mechanical cooling unit for circulating air over a set of cooling coils through the cabinet as well as through the room in which the keg is positioned.

A further important object is to provide air ducts leading from the storage room for the beer keg into the cabinet where the same is subjected to the cooling influence of the refrigerant coil and also providing an air duct leading from the cabinet to the storage room for delivering the cooled air to the latter and mounting a beer pipe from ‘the keg in the storage room to the faucet in said cold air duct to further lower the temperature of the beer before the same reaches the faucet.


Patent No. 878136A: Brew-House Equipment

Today in 1908, US Patent 878136 A was issued, an invention of Max Henius, for his “Brew-House Equipment.” There’s no Abstract, although in the description it includes this summary:

The gist of my invention lies in centering about a single point on the brew-house floor, on which the entire apparatus employed in producing the wort is located, all the controlling means for governing and inspecting the operation of the different parts, whereby all such means are rendered conveniently accessible to the manipulation and view of a single operator whose position of duty is at such centering point.


Patent No. 3559869A: Beverage Cooler

Today in 1971, US Patent 3559869 A was issued, an invention of John J. Reynolds, for his “Beverage Cooler.” Here’s the Abstract:

The application discloses a seamless, corrugated paper container having a top opening larger than its base and therefore capable of being nested with like containers. There is disposed therein a keg, bottle or the like of beverage desirably maintained in a cool state. The container may be coated with a moisture proof plastic and a coolant, such as ice, is disposed between the keg and the inner wall structure of the container. The latter is provided with a breakable aperture portion to receive a spigot assembly which communicates with the interior of the keg. The container also has a weakened area to receive, if desired, a drain hose, such area being below the expected water level of the container when the ice is substantially melted. Alternatively, the container is usable as an ice bucket in which case the weakened portions are not broken through.
