Patent No. 639761A: Underback

Today in 1899, US Patent 639761 A was issued, an invention of Frederick Orth and Frederick Schimper, for their “Underback.” There’s no Abstract, although in the description it includes these claims:

This invention relates to an improved construction of the underback, a vessel into which the unfermented beer flows from the hop-back to be conveyed by the pump to the surface cooler. Heretofore this underback was made in the form of a small open vessel which required constant watching and attendance to prevent an overflow and to regulate the ratio between inflow and outflow. If in spite of precautions an overflow would take place, the employees would be apt to become scalded, and the shutting of the cooks would be accompanied with considerable difficulty. By our construction all the above objections are overcome, and after the cooks have been opened and the pump started the beer will be delivered without liability of running over and without requiring any attention whatever.


Patent No. 511600A: Bottle And Stopper Therefor

Today in 1893, US Patent 511600 A was issued, an invention of Everett Ellis, for his “Bottle and Stopper Therefor.” There’s no Abstract, although in the description it includes these claims:

This invention relates to certain new and useful improvements in beer bottles and cork Stoppers therefor; and it consists substantially in such features thereof as will hereinafter be more particularly described.

In all manner of beer bottles heretofore employed in which cork-Stoppers are used it has been necessary always to employ a cork-screw or other implement for withdrawing the cork or stopper after the same has been forced or expanded into the bottle by any of the usual well known corking machines for the purpose. `The use of a cork-screw or other implement for extracting the cork or stopper is always attended with a great deal of trouble and inconvenience, besides wasting lots of time in many instances, and some forms of which are expensive as for instance that form of device usually applied to counters and which are designed to extract and cast away the cork by one movement of lever or handle.

The object of my invention is to provide a bottle and stopper therefor which shall enable the withdrawal of the latter from the bottle without the aid or use of any manner of cork-screw or other additional or outside device or implement whatsoever, thereby enabling beer or other similar liquids or fluids to be corked up in bottles all ready for use, and ready to be opened by a simple operation of the hand.


Patent No. 1985739A: Vehicle Body For Barrels

My invention relates Ito vehicle bodies for the transportation of barrels and particularly for the transportation of half barrels of beer.

The objects of my invention are to provide the economical and efficient handling of beer half barrels.


Patent No. 531356A: Apparatus For Carbonating Beer

Today in 1894, US Patent 531356 A was issued, an invention of Carl Barus, for his “Apparatus For Carbonating Beer.” There’s no Abstract, although in the description it includes these claims:

The object of my invention is to produce improved apparatus for impregnating beer, or the like, with carbonic acid gas.


Patent Nos. 3115149A & 3115150A: Tapping Valve For Beer Kegs

Today in 1963, both US Patent 3115149 A and US Patent 3115150 A were issued, and both are related inventions of Victor A. Sariotti and Arthur J. Tonna, assigned to the Burgermeister Brewing Corp., under the same name: “Tapping Valve For Beer Kegs.” There’s no Abstract, although the description for both patents is virtually identical, as is the accompanying drawings, although you can see a few minute differences if you look at them side by side:

This invention relates to the valve art, and more particularly to an improvement in a tapping valve for beer kegs.

One of the well known and long used beer keg pressurizing and dispensing systems is known as the Golden Gate system. in such a system the keg is characterized by the presence of a fitting in its upper wall for connection to a source of pressurized gas, a normally closed fill opening in its side Wall, a tapping valve fitted into the side wall adjacent the bottom wall, and a tapping device adapted to be fitted into the valve and locked thereto by rotative movement, the rotative movement being effective to open the valve. Reverse rotative movement of the tapping device serves to close the valve and to free the tapping device for disengagement from the valve.

In the valves of this type which are in use, the outlet port of the valve is located as much as an inch or more above the bottom of the keg. As a consequence, this port is uncovered to the pressurized gas before the keg is fully emptied. The keg still contains a number of quarts of beer. To minimize the loss of this beer, the keg is tipped, tipping blocks being regularly provided for this purpose, to maintain the valve outlet port submerged as long as possible. Even so, many ounces of residual beer remain in the keg and is lost to the purchaser.

it has been suggested that the valve be provided with a radially disposed tubular extension, the inlet opening of which is disposed immediately adjacent the bottom of the keg when the valve is open, thereby enabling substantially complete draining of the keg. The patent to Lamoureux 2,545,620 discloses such an arrangement. But while the tubular extension type of valve shown in this patent enables a substantially complete emptying of the keg, it does not lend itself to conventional keg handling practice.

Such kegs are returned to the brewery for cleaning while the valve is closed and subsequent refilling. Caustic solution is employed in the cleaning operation, and the tubular extension will entrap and retain an amount of cleaning solution, thereby rendering the use of such a valve unsatisfactory in practice.

In summary, the present invention is an improvement on the described tubular extension type of valve, in that means are embodied in the valve to render it self-clearing of cleaning fluids during the cleaning operation.


Patent No. 2226009A: Hop Separator

Today in 1940, US Patent 2226009 A was issued, an invention of George E. Miller, assigned to the Clemens Horst Company, for his “Hop Separator.” There’s no Abstract, although in the description it includes these claims:

This invention relates to a separator. and especially to a machine for separating stems, leaves and like foreign material from picked hops.


Patent No. 20100323060A1: Method Of, And Apparatus For, Flavor Recovery In Beer Brewing

Today in 2010, US Patent 20100323060 A1 was issued, an invention of Wilhelm Wolfgang-Peter, assigned to Krones Ag, for his “Method of, and Apparatus for, Flavor Recovery in Beer Brewing.” Here’s the Abstract:

A beer-brewing method, and an apparatus implementing the method, where vapors escaping from the wort during a boiling phase are passed, on the steam side, to a rectifying column connected to a wort boiler and the vapors are rectified, at least one flavor-containing distillate being recovered from the vapors and being fed to the wort following the boiling phase.


Patent No. 6666358B1: Beer Container

Today in 2003, US Patent 6666358 B1 was issued, an invention of William Field Warwick, for his “Beer Container.” Here’s the Abstract:

A beer container comprises an inner hollow shell of blow moulded PET to hold beer, an outer hollow shell of moulded high density polyethylene enclosing and supporting the inner shell and a spear structure including a dispenser tube extending from a bottom interior region of the inner shell through to a dispensing outlet at the top of the outer shell. The spear structure incorporates valves for supply of pressurizing gas into the interior of inner shell and for dispensing beer through the dispensing outlet, both valves being formed of PET. When the container has been emptied of beer, the outer shell can readily be separated from the inner shell and spear structure to allow separate recycling of the high density polyethylene material and the PET material.


Patent No. 2917906A: Portable Cooler, Gasser, And Dispenser For Keg Beer

Today in 1959, US Patent 2917906 A was issued, an invention of George Craig Woolley, for his “Portable Cooler, Gasser, and Dispenser for Keg Beer.” There’s no Abstract, although in the description it includes these claims:

This invention relates to a readily portable device for supporting and completely servicing a keg or small barrel of beer or other beverage which requires for proper draught and taste characteristics, cooling, gassing and controlled dispensing. My present invention is particularly designed and conceived for home rather than commercial use where it is desired to dispense a draught beverage such as beer to a group of people, from a keg.

At the present time the distributors of various malt beverages supply to their customers, cooling and gassing apparatus for small gatherings, usually employing a helical coil to be placed in a box of ice and an air pump or carbon dioxide cylinder of heavy construction. The apparatus is hooked up at the home and in many instances, the keg heats up (since only the discharge through the coil is cooled), the saturation level of the gas is consequently decreased in the beer and more gas is released, resulting in foam when the beverage is dispensed. The coil, if not thoroughly cleaned and sterilized after each use, is unsanitary and gives the next user an off taste beer; Cleaning time of such-coil requires from a half to a full hour and is often disregarded by the dissumption of the entire contents of the keg.

A further object is the provision of a device of the class described wherein a simple, compact wheeled chassis serves the multiple functions of a keg-support, a refrigerating chamber, a mounting for controlled gassing and dispensing mechanism and in addition, a valuable source of advertising for the distributor or manufacturer of the beverage.

Another object is to provide a compact, rugged device of the class described of simple and inexpensive construction affording a high degree of sanitation and provision for sterilizing of the few dispensing parts.


Patent No. 747729A: Automatic Filling Machine

Today in 1902, US Patent 747729 A was issued, an invention of William Koedding, for his “Automatic Filling Machine.” There’s no Abstract, although in the description it includes these claims:

My invention relates to machines for filling bottles and other receptacles with liquid, and has for its principal objects to produce a filling-machine which will operate automatically when the bottle is pressed against it in proper position to be filled, to equalize the pressure in the bottle with the pressure in the supply-pipe before the supply-pipe is opened to permit the liquid to How into the bottle, to provide for automatically stopping the flow of the liquid when the bottle is filled, and to prevent any stale liquid getting into the bottle.
