Patent No. 857843A: Beer-Service Apparatus

Today in 1907, US Patent 857843 A was issued, an invention of William F. Stark, for his “Beer-Service Apparatus.” There’s no Abstract, although in the description it includes this summary:

This invention relates to and has for an object to provide an improved beer service apparatus.

In the dispensing of liquids, more particularly malt beverages, the casks containing the same are usually stored in the cellar, and in the tap room, situated at some place on a higher plane than the casks, there are suitable faucets connected to the casks by a series of piping, the casks also being connected with a suitable pressure device, as for instance, a source of compressed air supply whereby the beverage is forced to the faucets and is there drawn as occasion may demand, the presence of the compressed air preventing the volatilization of the beverage and the escape of the entrained gas. During those portions of the day when the beverage is not being drawn from the faucets it will remain in the pipes between the casks and the faucets, and should the pipes have cooling coils connected with them, the beverage will become unduly chilled.

It is one of the objects of my present invention to provide means whereby the beverage may be returned from the pipes into the casks and there retained until it is again desired to force it to the faucets.

My present improvement makes use of the method of returning liquid under pressure to its receptacle by counter pressure and gravity, by employing means for connecting the draw faucet at its point of delivery to the counter pressure.

The passage of malt beverages through pipes has a tendency to gum and coat the inside of the pipes, rendering the same foul, and requiring frequent purging to keep them in a proper hygienic condition. The present improvement embodies means whereby the pipes may be filled with water for preventing them from becoming dry after the time the beverage has been returned to the cask and during the time the pipes remain idle, and also for the purpose of flushing and washing the pipes. This can be done by the employment of the present improvement without uncoupling the pipes from their connection with the casks or with the draw tubes which are ordinarily employed for establishing communication with the cask, and this while using a draw faucet of ordinary form.


Patent No. 3390000A: Separation Of Lupulin From Hops

Today in 1968, US Patent 3390000 A was issued, an invention of Robert J. Brison and John H. Litchfield, assigned to John I. Haas Inc., for their “Separation Of Lupulin From Hops.” There’s no Abstract, although in the description it includes this summary:

In the production of beer or ale one important ingredient employed is hops. Hops contain certain soft resins which impart not only bitterness to the beer, but also aroma. In the usual practice the hop cones which include the leaves, stems, petals, lupulin and at times, seeds, are boiled in their entirety within a sugary wort in order to extract the necessary resins and aromatic oils from the lupulin thereof. The lupulin particles are closed cup-like fibrous containers filled with hop flavoring substance including a relatively small amount of moisture, and essentially soft bitter resins and volatile aromatic oils.

It has been known however, that the flavor content of lupulin deteriorates in the ordinary practice of drying the hops prior to shipment to the brewery and that oxidation of lupulin occurs easily if the dried hops are not placed in sealed containers (preferably in an inert atmosphere) thus avoiding further oxidation thereof.

It will be recognized that such a procedure is costly since it involves packaging and handling extraneous -materials. Efforts dating back to the mid-nineteenth century have been directed to separating the lupulin from the hops although certain economic disadvantages have prevented their widespread acceptance. Further, many of these efforts result in a lupulin product excessively fragmented or crushed, thus exposing its valuable constituents to unnecessarily rapid and disadvantageous oxidation.

It is therefore an important object of the instant invention to overcome the disadvantages of prior art methods of separating lupulin from hops.

It is a further object of the instant invention to provide an improved method of separating lupulin particles from hops in the substantial absence of damage or comminution of said lupulin particles.

Another object of the instant invention is to provide an improved, simplified and economical method of separating lupulin particles from hops in the absence of appreciable particle size reduction and in the absence of appreciable oxidation or deterioration of the soft resin or volatile aromatic oil content `of said lupulin particles.

Still another object of the instant invention is to provide a simple, effective method of separating lupulin from hops which method can be implemented at the ranch or vine location and wherein the hops treated can be fresh (not dried, dehydrated or stored for any substantial length of time) or dried or a mixture thereof.


Patent No. 703206A: Beer-Tapping Apparatus

Today in 1902, US Patent 703206 A was issued, an invention of Patrick H. Keefe, for his “Beer-Tapping Apparatus.” There’s no Abstract, although in the description it includes this summary:

This invention relates to certain new and useful improvements in beer-tapping apparatus wherein an air-supply is in communication with the cask or barrel containing the beer or like liquid, and has for its object to provide means for furnishing a constant supply of air to the liquid, so that the latter may be drawn on through a pipe, which conducts the same to a suitable and convenient point.


Patent No. 3891781A: Process For The Extraction Of Hops

Today in 1975, US Patent 3891781 A was issued, an invention of Kurt Bauer, Helmut Findeiss, and Alfred Krempel, for their “Protective Coating for Cans and Methods for Application of Coating Thereto.” Here’s the Abstract:

Process for extracting from hops the essential brewing ingredients thereof, viz., neutral substances, bitter substances and tannin, which process comprises subjecting a primary extract solution of hops, e.g., in alcohol or hydrocarbon solvents, said solution containing as ingredients the neutral substances, bitter substances and tannin, to a first liquid-liquid extraction, wherein either (i) the tannins or (ii) the neutral substances are separated off, leaving a solution of (i) neutral and bitter substances or (ii) tannins and bitter substances, and subjecting the latter solution to a second liquid-liquid extraction to separate said solution into its components; the first extractant is desirably an aliphatic, cycloaliphatic or aromatic hydrocarbon when the primary extract solvent is an alcohol or aqueous-alcoholic solution, to result in extraction of the neutral and bitter substances in a hydrocarbon phase and leaving of the tannin in the alcoholic phase, whereafter the neutral and bitter substances are separated from each other by treating the extract with a second extractant, desirably aliphatic alcohol containing water.


Patent No. 2287500A: Sanitary Beer Comb And Cocktail Mixer Receptacle

Today in 1942, US Patent 2287500 A was issued, an invention of Peter Solinas, for his “Sanitary Beer Comb And Cocktail Mixer Receptacle.” There’s no Abstract, although in the description it includes this summary:

My invention relates to receptacles for cleansing beer combs and cocktail mixers.

Heretofore in the art where beer has been served over a bar it has been customary for the bartender to use a. beer comb to scoop off the excess top foam of a glass or stein of beer. The bartender by custom then places the beer comb in a glass of stationary water until he needs to use the beer comb again for another service. It is apparent that where a glass is used that the water is stationary and in a comparatively short time becomes stale and mixed with some of the beer leavings which have been introduced into the glass from time to time. It is obvious that very soon after the glass has first been used that the water will be so sour and distasteful that it will not properly clean the beer comb but will on the other hand leave the beer comb in such a condition that when the comb is next used to scoop out the top of a beer glass that the comb will leave stale drippings on top of the latest glass of beer to the distaste of a patron.

It is an object of my invention to provide a device whereby the beer comb may be conveniently held and entirely cleansed before each serving of a glass or stein of beer.

It is a further object of the invention to provide such a device in an accessible position and in which the beer combs may be easily placed.


Patent No. 4275097A: Protective Coating For Cans And Methods For Application Of Coating Thereto

Today in 1981, US Patent 4275097 A was issued, an invention of Frank L. Shriver, assigned to the Coors Container Company, for his “Protective Coating for Cans and Methods for Application of Coating Thereto.” Here’s the Abstract:

In a machine according to the invention a plurality of pairs of endless driving chains are arranged parallel with one another, each pair of chains having parallel runs between which the bine is adapted to be held transversely for movement relative to plucking means.


Patent No. 584863A: Beer-Tapping Device

Today in 1897, US Patent 584863 A was issued, an invention of Jay W. Farmoff, for his “Beer-Tapping Device.” There’s no Abstract, although in the description it includes this summary:

Our invention has for its object to produce an efficient tapping device which is simple and durable in construction, reliable in action, and which can be conveniently operated.


Patent No. 3257033A: Beer Dispensing Apparatus

Today in 1966, US Patent 3257033 A was issued, an invention of Reginald W. Stott, for his “Beer Dispensing Apparatus.” There’s no Abstract, although in the description it includes this summary:

This invention relates to a combined apparatus for the semi-automatic dispensing of a predetermined quantity of liquid and to the simultaneous counting of the number of such predetermined quantities of liquid which have been dispersed. A subsidiary aspect of this invention is a valve control means for use in that apparatus, and particularly a switch arrangement associated with said valve. The apparatus is particularly suited for the dispensing of effervescent liquids, and more particularly for the dispensing of beer.

It is necessary, in the dispensing of effervescent or gas charged liquids such as, for example, beer, to dispense such liquid, even by relatively inexperienced help, in such a manner that uniform results are obtained. It is also necessary that such dispensing means be capable of being set quickly and easily for the drawing of varying amounts of such liquids, i.e., for the drawing of two, or more, different sizes of drafts. Furthermore, it is desirable to have means associated with such dispensing means to count the total number of each size of drafts which have been drawn.

It was proposed accomplishing these ends by the use of an auxiliary storage tank where the required amount of beer was stored prior to dispensing. This proved undesirable, since this auxiliary storage, and the means used to dispense the beer therefrom, tended to have a detrimental effect on the delicate quality of the beer.

A prime feature, therefore, of the present invention, is the provision of apparatus whereby beer and similar liquids may be dispensed by relatively inexperienced help, in such a manner that uniform results are obtained.

A further feature is the provision of means whereby the apparatus may be quickly and easily set for the automatic dispensing of two or more different quantities, i.e., two or more different sizes of drafts.

A still further feature of this invention is the provision of counter means for the cumulative totalling of the number of each size of drafts which have been dispensed.


Patent No. 2121458A: Apparatus And Process For Aerating Wort In Yeast Production

Today in 1933, US Patent 2121458 A was issued, an invention of Wilhelm Vogelbuseh, for his “Apparatus And Process for Aerating Wort in Yeast Production.” There’s no Abstract, although in the description it includes this summary:

In the production of yeast, air is supplied to the wort during the fermentation in order to meet the oxygen requirements of the multiplying cells and also to render harmless the interchange products which are produced. Hitherto, compressed air from an air pump has usually been introduced into the wort through a rigidly mounted tube system which is placed horizontally at the bottom of the fermenting vat and the separate tubes of which are provided with holes. The attempts in recent years to reduce the size of the air bubbles have led to the diameter of the air outlet holes being reduced down to 0.3 mm. On account of the danger of stoppage and the difficulty of keep through such holes. Distributing devices provided with tubes or boxes of burnt clay, stoneware, sintered glass, etc. to act as air outlet surfaces have been used. The saving in power, however, does not correspond to the reduction of the amount of air as these materials, on account of their smaller permeability, require a higher operating pressure. keep such a body perfectly clean as is required for avoiding contamination.

The object of the invention is to avoid these disadvantages, and the invention consists in that a hollow body of suitable shape serving for delivery large openings and which, in the direction of movement, offers as little resistance as possible and allows the air to escape preferably in a direction different from the direction of movement and preferably at right angles or approximately at right angles thereto is moved through could hitherto only be obtained in the yeast industry by using the above-mentioned ceramic materials for the air supply member. In addition, it is difficult to ring the air into the liquid through comparative count of the above-mentioned disadvantages, have not become widely used.
