Patent No. 1646916A: Apparatus For Serving Out Beer

Today in 1927, US Patent 1646916 A was issued, an invention of Camilo Recuero and Gaudencio Lamarque, for their “Apparatus For Serving Out Beer.” There’s no Abstract, although in the description it includes these claims:

The present invention relates to apparatus for serving out beer and similar beverages and has for its object to provide an improved device of this kind capable of avoiding the disadvantages shown in the methods heretofore used.

As is generally known, in taverns, barrooms, or other places where beer is served out to consumers, this is generally effected from barrels and with the aid of carbonic acid under pressure, thus the conditions of expenditure, as regards satisfaction of the consumer and the amount of liquid wasted depend entirely upon the skill of the barman.

Further, during the hot season, the in crease in the demand for cooled beverages does not allow for sufficient time for serving out the liquid under normal. conditions so that waste is very likely to occur with the consequent losses to the proprietor of the place.

With the aid of the present invention all these disadvantages are avoided, since the improved device provides for an absolute control of discharge of foamless beer, or team alone, just as desired, whereby it is possible to serve out the beer or other liquid at complete satisfaction 0;! even the most exacting consumer and, simultaneously, there are no possibilities for any amount of liquid being wasted. As well, the present device constitutes an important improvement over the devices known in the prior art since it provides for more continuous dispensing.

The device according to the invention is characterized by. the fact that beer is admitted within a container of suitable form, size and material and, through the provision of tubes opening into discharge cocks combined one with the other, the discharge of the liquid, or of the foam formed by the pressure gas, may be exactly controlled so that the discharge is effected entirely at will. In this manner, when serving out’ a can or glass of beer, first-1y liquid beer without foam is discharged until reaching the desired limit, and then a suit able amount of foam is added until filling completely the can or glass used.


Patent No. 635474A: Keg Refrigerator

Today in 1899, US Patent 635474 A was issued, an invention of August Grap, for his “Keg Refrigerator.” There’s no Abstract, although in the description it includes these claims:

This invention relates to an apparatus for preserving the volatile hop essences or aromas coming from the copper or boiler in which the wort is boiled with the hops in order to improve the quality of the beer and like brews.

The method and apparatus comprised in the present invention consists in arranging a specially constructed condenser in communication with the top of a copper whereby the vapor arising from the heated contents of the latter will pass to and be condensed in the former.

The condensed vapor or steam is delivered to a supplementary cooling .coil and thence to a mixing chamber where it is brought into contact with the non-condensable or practically non-condensable odoriferous gases for fumes which pass from the upper end of the condenser and are collected and delivered to the said chamber in a convenient way.

The liquid resulting from the condensation of the steam or vapor given out from the copper absorbs the aroma of the odoriferous gases or fumes in the mixing chamber and as a result is richer in flavor and aroma than the original liquid contents of the said copper. The liquid is conveyed. from the mixing chamber to an open vessel or chamber from which it is delivered to a ferment ing vat.

My invent on applies more especially to} faucets for the dispensing of beer or other beverages kept on draft in bars or similar; places; and the chief object of my improvement is to keep the liquid in the faucet free from any metallic taint or flavor, and also to preserve it in a cool condition, ready to be discharged into the next glass in a perfectly palatable state.


Patent No. 209163A: Improvement In Barrels Or Kegs

Today in 1878, US Patent 209163 A was issued, an invention of William H. Ewing, for his “Improvement in Barrels or Kegs.” There’s no Abstract, although in the description it includes these claims:

My invention relates to certain improvements in barrels and other like packages, the heads of the same being of wood, arranged and secured in a novel manner, while the sides, or that part usually made of wooden staves, are made of sheet metal, which is manipulated in the following way: A sheet or plate of metal of suitable thickness and size is passed through a train of rolls or under a hammer in such way as to draw out or lengthen the middle of the plate in one direction. The object of this is to secure the requisite bulge or swell to the barrel or keg, both for convenience in handling and to give additional strength. The sides of the plate which correspond to the ends of the barrel or keg: are stamped or out in any convenient way, so as to form a series of three or more clips, a, thereon. These clips are used for securing the heads, and also chine-hoops, as presently described.


Patent No. 220773A: Improvement In Bungs And Stoppers For Casks

Today in 1879, US Patent 220773 A was issued, an invention of William H. Stewart, for his “Improvement in Bungs and Stoppers for Casks.” There’s no Abstract, although in the description it includes these claims:

My invention relates to bungs and stoppers for faucet holes in lager-beer and ale casks and kegs; and it consists in the exterior form of the bung or stopper, whereby it is adapted to be more easily driven into the cask or withdrawn therefrom when desired.

Heretofore such stoppers made of wood or cork are objectionable, for the reason that the gases readily penetrate the pores of such materials and leave the beer or ale unfit for use in consequence of becoming flat or stale. The wood and cork will become saturated with the liquid, and after being once used will become sour and injuriously affect the beer.

In the use of the elastic bung or stopper I find that great difficulty exists in extracting it in the form in which it has heretofore been made from the aperture in the cask or vessel, on account of the adhesive properties of the rubber, and this especially is the case when using it for lager-beer or ale casks, where the aperture is wood or iron bound. If the bung or stopper is made very hard, or even hard enough to drive easily in the aperture, there is no certainty that the aperture will be perfectly sealed, as the harder the composition the less the elasticity,and the less the certainty of its filling any irregularities that may exist in the aperture. On the contrary, if the composition be made softer to gain more elasticity, then the difficulty of driving in the bung or stopper occurs, as the composition sticks and adheres to the sides of the aperture, and after as shown in Fig. 5, being once driven in is very difficult to extract.

The special object of my invention is to overcome these several difficulties by making a bung or stopper which can be readily driven in or extracted, and which will also perfectly seal the aperture in the cask.


Patent No. 7604147B2: Keg With An Inner Bag

Today in 2009, US Patent 7604147 B2 was issued, an invention of Ian Anderson, assigned to Anheuser-Busch InBev S.A., for his “Keg with an Inner Bag.” Here’s the Abstract:

An interlocking collar (72) secures a bag neck (46) in a keg aperture (42) of an alcohol beverage keg container (22). The interlocking collar is mounted in press fit surrounding relation with a peripheral wall portion of the bag neck. The collar has an outer peripheral wall portion sized larger than that of a keg aperture. The collar (72) has a recessed groove (76) in the collar outer peripheral wall portion for receiving in press fitting and sealing relation a keg flange (40) that defines the keg aperture. The collar outer peripheral wall portion has a resilient edge portion (78) adjacent the recessed groove that deflects to permit the interlocking collar to pass through the keg aperture and receive the keg flange in the recessed groove. The interlocking collar has a plurality of locking passageways (80) placed around the interlocking collar and axially extending through the interlocking collar between the neck and recessed groove. A latch member (82) has a plurality of locking fingers (84) that extend axially through the locking passageways to prevent deflection of the resilient edge portion of the interlocking collar after the collar is placed in the keg aperture.




Patent No. 3613954A: Dispensing Apparatus

Today in 1971, US Patent 3613954 A was issued, an invention of Peter D. Bayne, assigned to Schlitz Brewing Co., for his “Dispensing Apparatus.” Here’s the Abstract:

The invention relates to a dispensing unit for dispensing a beverage containing dissolved carbon dioxide and which utilizes a liquified fluorocarbon gas as a pressurizing medium. The unit includes a closed container containing a beverage having dissolved carbon dioxide. The liquified fluorocarbon gas is contained i a separate reservoir which communicates directly with the headspace of the container above the liquid level. As the beverage is drawn from the container, the volume of the headspace of the container increases, thereby decreasing the pressure in the headspace and resulting in the vaporization of additional quantities of the liquified fluorocarbon gas which act to maintain the desired counterbalancing pressure within the headspace to keep the carbon dioxide in solution in the beverage.


Patent No. 2096088A: Method And Apparatus For Conditioning And Dispensing Beer

Today in 1937, US Patent 2096088 A was issued, an invention of Lioyd G. Copeman, for his “Method and Apparatus For Conditioning and Dispensing Beer.” There’s no Abstract, although in the description it includes these claims:

This invention relates to a method and apparatus for conditioning and dispensing beer, and has to do particularly with beer conditioning and dispensing apparatus of the portable type.

One of the main objects of the present invention resides in the use of solidified CO2 as a cooling and conditioning medium. A further feature of the invention has to do with the immersion of beer conditioning and dispensing means directly in the beer itself, but in such a manner that the beer is not cooled below normal palatable temperature; in the preferred form the beer is even pre-cooled before being placed in the container whereby the main function of the-immersed means is to condition the beer and to some extent maintain the same in its cooled condition.

Other features have to do with wall structure for separating the solid CO2 from the liquid and having a predetermined insulating effect whereby heat transfer will be so retarded as to keep the beer above its minimum palatable temperature.

Other features include the general structure of the portable container and also details of regulable conducting means for varying temperature of the liquid, as-will be more clearly set forth in the specification and claims.


Patent No. 3279493A: Valve Assembly For Kegs

Today in 1966, US Patent 3279493 A was issued, an invention of David Zurit and Michael J. Parisi, assigned to the Tap Rite Products Corp., for their “Valve Assembly For Kegs.” There’s no Abstract, although in the description it includes these claims:

This invention relates to apparatus for tapping liquid containing vessels, such as beer kegs. The invention will be described as embodied in beer-tapping apparatus, but some features are not so limited within the scope of the appended claims. More particularly, the invention relates to apparatus that fits into the tapping hole of a keg and that has a valve which seals the opening when in one position and which leaves the interior of the keg in communication with a beer line or faucet when in another position.

It is an object of the invention to provide tapping apparatus of the character indicated with an improved vertically extending inlet that can be made long enough for withdrawing the contents of the keg down to the last few ounces of liquid within the keg.

It is a more specific object of the invention to provide a valve of the character indicated with an inlet fitting that turns with the valve and that moves into a position where it is exposed to the free flow of cleaning fluid in the keg when the valve is closed and the keg is in position for Washing.

It is another object of the invention to provide an improved valve construction with a static sealing disk having a novel structure for preventing rotation of the seal and having a shape that forms with the other parts of the apparatus a channel for unobstructed drainage of cleaning fluid from the inlet fitting of the value.
