Today in 1962, US Patent 3022617 A was issued, an invention of John Miller and Vincent J. Russoman, assigned to Schaefer Brewing Co., for their “Attachment for Conveyor Keg Palletizing Device.” There’s no Abstract, and given that there are a record (for me at least) 45 drawings showing the patented device, there’s precious little by way of description, so I guess just look at the pretty pictures.
Today in 1957, US Patent 2782013 A was issued, an invention of Edwin L. Dittrich, assigned to Pfaudler Co. Inc., for his “Lauter Tubs.” There’s no Abstract, and the OCR didn’t work very well on this one, so it’s hard to read. What I can make out is that “this invention relates to lauter tubs and has for its object to provide several improvements thereto.
A lauter tub is essentially a device for straining wort liquid from the mash-grains; and comprises -a perforated false bottom resting on and separated from the tank bottom itself by spacer studs attached to the false bottom. The tank bottom is provided-with suitable drainage openings. The invention provides a combined gear drive and hydraulic system unit motivating the shaft which revolves in a universal bearing attached to the bottom of the tank, said shaft having vertical freedom of movement through out lifting the false bottom.”
Today in 1947, US Patent 2416007 A was issued, an invention of Hans Joachim, for his “Method of Clarifying and Stabilizing Beer and Like Beverages.” There’s no Abstract, but it’s described as an “invention relates to a process for treating beer or similar beverages, whereby the beverage is improved in clarity, stability and qualities of brilliance and sparkle, and which preserves and enhances taste and bouquet of the product.”
Today in 1975, US Patent 3867551 A was issued, an invention of Yves Germain Jaegle, for his “Preparation of Beer.” Here’s the Abstract:
Beer is prepared by a process wherein groups of batches of wort are turned serially at temperatures increasing from 10 DEG to 14.5 DEG C into a cylindrical, vertically disposed vat having a conical bottom. Convection currents are instituted to homogenize the contents of the vat and fermentation is carried out until a beer of the desired degree of fermentation is formed. The resultant beer is mellowed by a warm keep phase, cooled and subjected to a cold keep phase.
Today in 1998, US Patent 5718161 A was issued, an invention of Leigh P. Beadle, for his “Beer Brewing System And Method.” Here’s the Abstract:
There is provided a system for brewing beer particularly suited for a brew pub setting. The invention utilizes a cooker to heat water and a pre-blend syrup of ingredients. Once the beer mixture is boiled for a sufficient length of time in the cooker, the mixture is transferred to a brewing vessel. A spiral spray nozzle is used to add water to the brewing vessel in a conical spray pattern which causes the water to be oxygenated once it passes through the spiral spray end of the nozzle. Yeast is added to the brew mixture and oxygenated water in the brewing vessel. The beer mixture is permitted to ferment in the brewing vessel for a sufficient length of time. The fermented beer mixture is transferred to a plurality of kegs, each of which contains a mixture of sugar and gelatin. The sugar and gelatin allow the beer mixture and age and clarify. Once the beer mixture has aged a sufficient time, the beer mixture is dispensed from the kegs. The system of the invention includes a keg cleaning device for simultaneously depressurizing the keg while hooking up the device to the keg.
Today in 1882, US Patent 253683 A was issued, an invention of Peter J. Catterall and Edward Birch, from Manchester, England, for their “Apparatus for Raising Beer.” There’s no Abstract, but the application states their “invention relates to apparatus for raising valves, through one of which the liquid is admitted to the chamber, and through the other the liquid is forced to the bar or delivery-tap” and there “is a section of the three-way tap that admits and discharges the water used to raise the beer or other liquid.”
Today in 1906, US Patent 812243 A was issued, an invention of Max Stahl, for his “Circulating System for Beer-Filters.” There’s no Abstract, but Stahl describes his invention as an improvement over then-current systems, saying his “invention aims to and does overcome the losses and disadvantages [mentioned earlier in the description], and in brief it consists of providing means whereby the column of beer can be switched off the racking-bench and continuously returned to the filter until stable relations are secured and the beer no longer runs cloudy or contains fibers of filter mass.”
Today in 1958, US Patent 2823125 A was issued, an invention of Frank H. Schwaiger, assigned to Anheuser-Busch, for his “Apparatus for and Process of Fermenting Beer.” There’s no Abstract, but in the description it states the following:
One of the principal objects of the present invention is to provide an improved fermenter which can be fabricated from stainless steel and which requires no overhead chamber for capturing foam which must necessarily rise upwardly into said chamber. Another object is to provide an improved fermenter which requires no special housing, which is easily housed on a single floor of a building, which can be easily cleaned, which requires less space per unit capacity, and which separates the foam from the beer more completely and more efficiently. Another object is to provide a fermenter construction which moves the foam automatically toward the foam chamber. Another object is to provide a fermenter which without moving parts automatically prevents beer from spilling over a baffle into the foam chamber even though the beer increases in volume during fermentation. Another object is to provide a fermenter which can be fabricated in a metal fabricating shop, shipped to the brewery, and placed upon a suitable base therein.
Another principal object of the present invention is to provide an improved process wherein the foam condensate is directed back into the manufacturing process at a different point from where the foam was taken. Another object is to provide a process wherein the foam condensate can be filtered or treated before it is redirected into the process.
Today in 1914, US Patent 1086931 A was issued, an invention of George Anton Orth and Joshua J. White, for their “Fluid-Separator.” There’s no Abstract, but in the description it states the “object of the invention is to provide a separator, particularly adapted for use in connection with ales and beers, for separating sediment from the body of the fluid.” The description continues:
The invention embodies among other features a device provided with an inlet pipe for connection with the main barrel or the keg and an outlet pipe for connection with the tap or faucet, the mentioned pipes terminating in a container, with an end of the inlet pipe terminating in a separator cup provided with a valve operable by a float arranged within the container and movable upwardly therein as the depth of the fluid in the container increases, the float in its upward movement being adapted to close the inlet pipe to prevent the entrance of additional fluid and in its downward movement being adapted to permit the valve to open to admit more fluid to the container.
By connecting our device directly with the keg or barrel, the pressure in the device will be the same as in the keg or barrel, so that when the fluid is taken from the tap it will be as fresh as if it were taken directly from the keg.
Today in 1910, US Patent 948463 A was issued, an invention of Frank C.H. Strasburger, for his “Filling-Machine.” There’s no Abstract, but according to the description, the “invention relates to’ machines for filling bottles with beer or other charged liquids and its object is to accomplish the filling operation without the loss of gas in suspension in the liquid and without the production of foam in the bottles. Attainment of this primary object of the invention also has for its object to utilize the pressure in the liquid tank for closing the liquid valve; to establish a counter-pressure in the bottle before the liquid valve is opened; to operate the liquid valve by a diaphragm and cause the valve to open by equalizing the pressure on both sides of the diaphragm; and to close the liquid valve by exhausting the pressure on one side of the diaphragm.”
