Patent No. 3212335A: Beer Keg Measuring Device

By

patent-logo
Today in 1965, US Patent 3212335 A was issued, an invention of Joseph A. Guiffre, for his “Beer Keg Measuring Device.” There’s no Abstract, although in the description it includes this summary:

In the industry wherein the device of my invention is to be utilized, tap beer is sold to taverns and bars in metal kegs which are loaded in the brewery under pressure. Due to the pressure constantly maintained within a filled or partially filled keg of beer no practical device has as yet been found in the industry which will permit the operator of the business, wherein the beer is sold at tap, to determine the amount of beer sold at any interval of time, or the amount of beer which he has left in an opened or used keg. Because of his inability to determine this needed information, the shop keeper is often times inconvenienced at a rather busy hour to change from a keg which has just been emptied to another fresh keg.

Moreover, in not being able to accurately determine the amount of beer sold within a certain period of time, as for example, from the open of a business day to its close, the owner of such business is unable to determine if he is getting all the receipts which should be forthcoming from each keg of beer or ale.

An object of my invention is to provide a pressure keg measuring device which can be quickly connected to measure the amount of beer remaining in a used keg of beer or ale yet under pressure.

A further object of my invention is to provide a pressure keg measuring device which can be quickly connected to measure the remaining beer in a keg under pressure, while the keg of beer is in its usual position under the dispensing fountain in a tavern or bar.

Another and further object of my invention is to provide a beer measuring device for pressure beer kegs which is simple in construction, economical to manufacture, and which will provide the user with a device which can easily and quickly be connected to a keg for measurement of the quantity of beer or ale remaining therein.

Patent No. 3279534A: Percolator For A Brew Kettle

By

patent-logo
Today in 1966, US Patent 3279534 A was issued, an invention of Robert C. Gadsby, Joseph Schwaiger and Frank H. Schwaiger, assigned to Anheuser-Busch, for their “Percolator for a Brew Kettle.” There’s no Abstract, although in the description it includes this summary:

One of the principal objects of the present invention is to provide an improved percolator for brew kettles, such as are used in the brewing industry. Another object is to provide in such a percolator a plurality of flat heating sections which can be easily cleaned and replaced or repaired if necessary. Another object is to provide an improved percolator design which is shaped to distribute heat in a predetermined manner :and which is shaped so as to create a natural flow of the liquid being heated within the percolator. Another object is to provide a percolator of a design in which there is little likelihood of trapping condensate therein. Another object is to provide connectors between the relatively flat heater sections which prevent entrapment of the liquid so as to prevent the overheating of any liquid which might otherwise become entrapped.

Today in 1995, US Patent 5458253 A was issued, an invention of Michael Shapcott, for his “Bottle Cap.” Here’s the Abstract:

A crown seal for sealing an opening of a bottle including a flange having between twenty-eight and thirty-two flutes around the circumference thereof. Each flute comprises depression having a generally triangular surface area between a pair of ridges. The additional flutes provide more points of contact with the bead are provided, ensuring a securement of increased strength between the crown and bottle.

Patent No. 3765903A: Isomerised Hop Extract

By

patent-logo
Today in 1973, US Patent 3765903 A was issued, an invention of Brian Clarke, Robert Hildebrand, David Lance, and Alexander White, assigned to Carton and United Breweries Ltd, for their “Isomerised Hop Extract.” Here’s the Abstract:

A process for the preparation of an isomerised hop extract for use in the flavouring of food or beverages which comprises adding to a solution of humulones or their salts a metal ion of calcium, magnesium, nickel, manganese or zinc, which metal ion forms with the humulones a metal ion-humulone complex which then precipitates from the solution. The metal ion-humulone complex is then heated in solid or paste state or in suspension or dissolved in an organic solvent to form a metal ion-isohumulone complex in high yield. The metal ion-isohumulone complex is substantially insoluble and can be used as a bittering additive, without regeneration to a soluble salt of isohumulone, by finely grinding such metal ion-isohumulone complex.

Today in 1990, US Patent 4963175 A was issued, an invention of Donald E. Pace, for his “Keg Cooler Tub.” Here’s the Abstract:

A transportable keg cooler tub comprising a circular tub-like base with a pliable flexible canvas sleeve extending upwards from the top edge of the base. The sleeve enclosing a plastic liner in intimate contact with ice cubes filling the space between the liner and the enclosed beverage keg. A portion of the plastic liner pulled through an orifice on the bottom outside perimeter of the base providing drainage for the ice contained by the plastic liner.

Patent No. 5564568A: Insulating Cover For Keg Beer

By

patent-logo
Today in 1996, US Patent 5564568 A was issued, an invention of Pleasant P. Rankin, Sr., for his “Insulating Cover For Keg Beer.” Here’s the Abstract:

An insulating cover for keg beer. The cover consists of a relatively flexible insulating material which substantially surrounds one or more kegs of beer. In a first embodiment the cover closely conforms to a single keg of beer, and thus has a cylindrical shape. Handles are provided on the exterior of the cover for easier manual transport of the keg and cover combination. The insulative properties are sufficient to maintain a relatively constant cool temperature without the use of ice, although multiple-use sealed freeze packs may be placed within the cover. In a further embodiment the cover is sized to fit upon a pallet and enclose up to four kegs. A side wall and top of the cover is openable to remove one or more of the kegs.

Patent No. 2017365A: Device For Tapping Kegs

By

patent-logo
Today in 1935, US Patent 2017365 A was issued, an invention of August L. Klein, assigned to the Blatz Brewing Company, for his “Device For Tapping Kegs.” There’s no Abstract, although in the description it includes this summary:

This invention relates to apparatus for increasing the pressure in beer kegs; and more particularly, a utility device which may be used where expensive tapping apparatus is not available.

Although my invention is not limited to the dispensing of beer, beer is often stored in kegs and at picnics and other functions, difficulty is experienced in dispensing the same. It is common practice to place in the side of the keg a wooden spigot, but due to lack of internal pressure, the beer or liquid flows very slowly. My invention increases the internal pressure so that the contents of the keg are under pressure and will be forced out through the spigot.

The prime object of the invention is to provide quickly attachable means whereby the internal or head pressure may be increased, thus facilitating the dispensing of the contents of a drum or keg.

Another object is to provide means for indicating the internal pressure so that the operator will be guided in this respect.

By

patent-logo
Today in 1996, US Patent 5564602 A was issued, an invention of James Cleland and Melvin Kyees, for their “Beer-Dispensing System and Apparatus.” Here’s the Abstract:

A beer-dispensing apparatus including a source of cooled pressurized gas-ladened beer, an elongate beer delivery line extending from the source of beer to a remote beer-dispensing station, a normally closed beer-dispensing valve at the beer-dispensing station, a liquid glycol chilling and recirculating unit, a heat exchanger beer delivery structure including an elongate beer-conducting balance line smaller in inside diameter than the beer delivery line and connected with and extending between the beer delivery line and the valve, an elongate glycol-conducting tube extending longitudinally of and in heat transfer relationship with the balance tube and connected with the glycol chilling and recirculating unit to cause chilled glycol to continuously circulate through it; a thermally insulated heat-storing aluminum body about the balance and glycol tubes; glycol flowing through the glycol tube progressively lowers the temperature of beer flowing downstream through the balance tube to the valve.
