Patent No. 220595A: Improvement In Tapping And Venting Barrels

Today in 1879, US Patent 220595 A was issued, an invention of Edward Fitch, for his “Improvement in Tapping and Venting Barrels.” There’s no Abstract, although in the description it includes these claims:

This invention relates to an improved method or process of tapping and venting barrels, casks, or other vessels containing liquids, and consists- First. Of a faucet provided with an air-duct passing partly through the same lengthwise, preferably near the upper side thereof, and terminating near the inner end of the faucet in an opening upon the side of the faucet.

Second. This air-duct is controlled by the spigot of the faucet, and is opened or shut by turning the spigot. The spigot is provided with two openings, one above the other-the upper one for the admission of air to the airduct, and the lower one for the emission of the liquid contents of the barrel. The lower opening is made larger than the upper one, and in such position in the spigot that by partially turning the spigot the liquid will flow while the air-duct remains closed, and by further turning the spigot the air-duct will also be opened. The spigot can thus be made to open both passages at the same time, or to close both passages at the same time, or to open the lower passage for the flow of the liquid while the upper or air passage or duct remains closed.

Third. The head of the barrel,’cask, or other vessel to be tapped and vented is provided with an air duct or passage passing in a straight line through the substance of the head at right angles with the axis of the barrel, and opening at the lower end of the said air duct or passage in the upper side of the orifice in the said head through which the liquid is to be drawn, and at the other end thereof into the barrel at or near the junction of the head with the staves of the barrel, thus opening a duct or passage from the orifice in said head to the air-chamber in the upper side of the barrel when the same is placed upon its side in position for drawing the liquid.

The principal object of the invention is to provide means for absorbing blows and sudden shocks delivered longitudinally of the barrel on 5 the end edge, thereby preventing injury to the body of the barrel and to the lining material therein.


Patent No. 2451156A: Process And Apparatus For Producing Alcohol By Fermentation

Today in 1984, US Patent 2451156 A was issued, an invention of Annibal Ramos De Mattos, for his “Process and Apparatus for Producing Alcohol by Fermentation.” There’s no Abstract, although in the description it includes these claims:

This invention relates to a process and apparatus for yeast fermentation and, more particularly, for producing alcohol by fermentation.

Commercially, alcohol is customarily produced by a batch or a modified batch process. In such processes the yeast necessary to convert the nutrient medium or wort into alcohol must be grown on the wort or on an outside nutrient medium. Yet as the conversion of the wort to alcohol takes place and the concentration of alcohol increases, the medium becomes toxic to the yeast. As a result, the alcohol ultimately present in high concentration kills a certain portion of the yeast, and the wort consumed in the production of this yeast is lost. Additionally, in such processes the concentration of yeast and its contact with the nutrient medium is seldom best adapted for optimum rate of alcohol conversion.

In the production of alcohol by conventional fermentation processes, it is usually necessary to kill or prevent the growth of bacteria which are deleterious to the propagation of the yeast or impede the conversion of the nutrient medium to alcohol. These deleterious bacteria are controlled either by subjecting the wort to heating at sterilization temperatures or by the introduction of chemical bactericides such as sulfuric acid, hydrochloric acid, fluorides, copper sulfate, and the like. It is also known that nutrients suitable for conversion to alcohol by fermentation, particularly cheaper nutrients such as low grade sugar, seldom contain all the elements necessary for the nutrition and propagation of the yeast which convert the nutrient into alcohol. As a result, the conventional nutrient medium must be complemented by the addition of so called stimulants such as the various mineral salts including, for instance, sulfates and nitrates of ammonia, calcium super-phosphates, and the like, or organic substances such as urea, malt, peptone, and the like.

The known commercial processes of producing alcohol by yeast fermentation may be divided roughly into four types; namely, progressive filling, division, continuous feeding, and a fourth process in which the yeast is recovered and reused in subsequent fermentation vats.

In the first-mentioned process a group of vats is placed in series and fermentation initiated in one of the vats. When the fermentation has reached a desired point, a portion of the fermenting wort in the first vat is transferred to a second vat to initiate the fermentation therein and so on for any desired number of vats.

In the second-mentioned process the contents of one vat is used for the purpose of inoculating other vats. For instance, after a group of vats has been used for fermenting wort to alcohol, one of the group is not discharged but is retained for the purpose of distribution to the vats which have been discharged for the purpose of initiating the fermentation of fresh wort.

The third-mentioned continuous feeding process is a very old process introduced by Guillaume, involving inoculating a multiplicity of fermentation vats from a culturing vat.

The fourth process is of more recent origin and was patented by Melle and Bolnot. In this last-mentioned process the pH of the fermenting wort is carefully controlled to approximate a pH of 3. When the fermentation is nearly complete, the partially spent wort and yeast are passed into a centrifuge where the yeast is recovered in the form of a liquid containing a high concentration of yeast. This liquid is used for the purpose of initiating the fermentation of a new charge of wort. This latter process has a number of disadvantages involving, as it does, the necessity for controlling pH of the fermentation mass and requiring the addition of conventional stimulants and the like used in other fermentation processes. The centrifuging device involves added equipment costs. The process makes possible some saving in fermentation equipment but not nearly so much as is possible in accordance with my continuous process described in detail hereinafter.


Patent No. EP0091322A2: A Brewing Unit

Today in 1983, US Patent EP 0091322 A2 was issued, an invention of Noel Roy Wilkinson, for “A Brewing Unit.” Here’s the Abstract:

An improved brewing unit in which energy is saved by providing a mash tun (14), hot water tank (10) and kettle (8) in a single unit (1), by partially enclosing the mash tun with the tank and if necessary pre-heating the water supply to the tank by using the heat from wort coolers provided between the unit (1) and fermentation tank (83, 85); further improvements are provided by constructing the kettle as a combined kettle and whirlpool in a single chamber having a circular wall (2) and a tangential inlet (92) to the wall, a pump (53) and wort boiler (6) being in circuit with the kettle so that wort is continuously circulated through the boiler and tangential inlet to the kettle whilst the worts are boiled. The combined kettle and whirlpool saves space and enables the process of brewing to be shortened with resultant savings in both energy and brewing time.



Patent No. 4409246A: Yeast Strain For Fermenting High Plato Value Worts

Today in 1983, US Patent 4409246 A was issued, an invention of Graham G. Stewart, Thomas E. Goring, and Ingeborg Russell, assigned to the Labatt Brewing Company, for their “Yeast Strain For Fermenting High Plato Value Worts.” Here’s the Abstract:

The yeast is a strain of Saccharomyces cerevisiae and has been deposited at the National Collection of Yeast Cultures, Norwich, England under the number 962. Morphologically the giant colony of the novel strain can be described as a circular colony having a slightly serrated periphery, a convex surface topography with a central, globular dome and exhibiting primary concentric convolutions and secondary radial convolutions which, in combination, impart a rough appearance to the surface. The novel ale strain has the advantages that it is effective in worts having high plato values and is a bottom-cropping strain.


Patent No. 527123A: Means For Transporting Beer

Today in 1894, US Patent 527123 A was issued, an invention of Valentin Oppl, for his “Means For Transporting Beer.” There’s no Abstract, although in the description it includes these claims:

My invention relates to means for transporting beer, and the invention consists in a four-wheeled vehicle having a tank permanently thereon, pumps connected with the tank and power mechanism to operate the pumps.


Patent No. 3106522A: Hop Separation Flights

Today in 1963, US Patent 3106522 A was issued, an invention of Florian F. Dauenhauer, for his “Hop Separation Flights.” There’s no Abstract, although in the description it includes these claims:

The stripping of hops from hop vines by mechanical means results in the by-product of mixtures of considerable foreign material and stripped hops; such foreign material including vine fragments, branches, leaves and leaf fragments as Well as long and short stems all comrningled with individual hops. And, it has continuously been a problem in the art to reduce such foreign material to a minimum in order to avoid deleterious factors in beverages utilizing hop. The present invention is directed to the provision of means for effecting the separation of an appreciably increased quantity of leaves and leaf fragments at a hop-cleaning stage prior to the final cleaning stage so that the end result is appreciably cleaner hops having much less than 1% of foreign material intermingled or commingled therewith.

A primary object of the present invention is to provide hop separation flights capable of effecting the removal of substantial quantities of leaves and leaf fragments from moving mixtures of hops intermingled and commingled with foreign material, including leaves and leaf fragments.

Another important object of the invention is to provide improved hop separating flights of the indicated nature which are additionally characterized by their ability to relieve the load on the final cleaner or clean-up separating equipment and make the latter more effective in reducing the quantity of foreign material in mixtures of hops and foreign material.

A still further object of the present improvement is to provide hop separation flights of the aforementioned character which can readily be installed at a minimum of expense for utilization with hop separating machines of any type.


Patent No. 40200A: Improved Apparatus For Cooling Beer

Today in 1863, US Patent 40200 A was issued, an invention of Henry Steubing, for his “Improved Apparatus For Cooling Beer or Other Liquids.” There’s no Abstract, although in the description it includes these claims:

The said apparatus is used in the following manner: Cold water or iced water is introduced into the space d from a reservoir, until the space d is filled with it and during the whole time of cooling. Then the ale, beer, or other liquid to be cooled is admitted into the hollow cylinder c steadily and continuously, when the same Will overflow into the space formed by the flange e, and will 110W down through the holes n n’ n on the outer mantel, a, into the space formed by the lower flange, j’, after which it flows out of the apparatus through the pipe i. Thus it will be seen that a certain quantity of iced water or cold water cools the ale, beer, or other liquid, rst by its contact on the inside b of the cooler, and then by its contact on the outside c of said cooler, thereby effecting `a great saving of the cooling material.


Patent No. 936011A: Apparatus For Making Malt

Today in 1909, US Patent 936011 A was issued, an invention of George J. Meyer, for his “Apparatus For Making Malt.” There’s no Abstract, although in the description it includes these claims:

Heretofore malting has usually been effected by tumbling barley or other grain around in rotatable drums or turning the same over periodically by hand or mechanical shovels while the same is supported in thin horizontal layers on a floor or in shallow boxes. None of these systems utilize the overhead space in the rooms of malt houses and therefore are not economical in this respect,

One of the objects of this invention is to utilize this overhead space to the fullest extent and thereby increase the malting capacity of a building of certain dimensions.

My invention has the further object to simplify the means whereby malting is effected so as to reduce the cost thereof and also insure a more thorough mixing of the barley from time to time during the malting operation so as to insure a more uniform product.


Patent No. 771495A: Bushing For Beer Or Ale Kegs Or Barrels

Today in 1904, US Patent 771495 A was issued, an invention of Florian M. Pfluger, for his “Bushing for Beer or Ale Kegs or Barrels.” There’s no Abstract, although in the description it includes these claims:

This invention relates to an improvement in bushings for bung-holes of beer and ale kegs, barrels, or similar receptacles; and the object of the invention is to provide abushing which can be readily secured in a bung-hole and which will form a liquid-tight joint between its outer surface and the surrounding wall of said hole. With the forms of bushing commonly employed for this purpose it is found that before the barrel or other receptacle is otherwise unfit for use the metal lining of the bunghole will become loosened and permit leakage of the contents of the receptacle. By the present invention means are provided where the grip or hold of the bushing on the wooden wall of the bung-hole may be maintained even after years of use, so that the life or usefulness of the receptacle will be greater than if bung-hole linings of the form heretofore employed are used.
