Patent No. 3174650A: Bung Withdrawing Assembly

Today in 1965, US Patent 3174650 A was issued, an invention of Frank A. Bellato, for his “Bung Withdrawing Assembly.” There’s no Abstract, but the description states simply that the “invention relates to a device for removing the wooden bungs from beer kegs and similar containers after such kegs have been emptied of their contents.” Then the goals of their patent application are laid out:

A major object of the invention is to provide an auger, of special form for the purpose, having a pilot portion arranged so as to first penetrate the bung along a path axially of the bung without possible deviation from such path such as grain direction or irregularities in the wood of the bung might cause, and having a portion following the pilot portion arranged to then advance into the bung in a manner to cause the bung to be withdrawn from the bung hole and split into separate sections so that such sections will fall of themselves from the auger.

It is another and important object of the invention to provide a means for operatively mounting the auger, both for rotation and axial movement, in an upwardly facing position, and a means for supporting the keg above the auger in such a position that the bung, which as usual is in one side of the keg, will be disposed in a downwardly facing position directly in line with the auger.

The importance of having the bung disposed in an inverted position, with the auger disposed below the keg and bung, is that no chips or wood dust, as created by the action of the auger, can enter the keg but will drop down clear of the keg.

A further object of the invention is to provide a catch tray and carryotf chute in connection with and directly below the auger which will receive, and cause to be carried alway, all chips, withdrawn bung pieces, as well as any liquid residue dropping from the empty keg when the bung is withdrawn, and keep such waste matter from possibly fouling the auger supporting and operating mechanism.

The keg, when initially placed on the supporting means, may not always be disposed with the bung in the necessary downwardly facing position, and a still further object of the invention is to provide a keg support-ing means which enables the keg, after once being supported, to be easily rotated so as to dispose the bung in the proper position for engagement by the auger.

In connection with this latter feature, it is also an object of the invention to provide a clamping unit for engagement with the top of the keg, which will rst exert a yieldable hold-down action on the keg which still allows the keg to be rotated if necessary, and which will then clamp the keg against any movement. At the same time, the clamping means is mounted so that it can be readily moved clear of the keg so as to offer no interference with the placement of the keg on or removal of the same from the supporting means.


Patent No. 3649993A: Apparatus For Opening The Flaps Of A Container And Removing Debris Therefrom

Today in 1972, just one year ago, US Patent 3649993 A was issued, an invention of Henry Sauer, assigned to Schlitz Brewing Co., for his “Apparatus For Opening The Flaps Of A Container And Removing Debris Therefrom.” Here’s the Abstract:

An apparatus for opening and spreading the top flaps of a carton containing packaged articles such as bottles, and for cleaning the carton after the flaps are opened. The carton containing the articles is moved along a conveyor and the sides of the carton are engaged by pressure members which deform the sides and pivot the flaps, if closed, to a partially open position. The carton then passes beneath a vacuum duct, which acts to raise the flaps. After the flaps have been raised, the carton moves into engagement with a spreader unit which spreads the flaps laterally outward. With the flaps in the spread position, the carton is then conveyed beneath a second vacuum duct which acts to draw lightweight debris from the carton.


Patent No. 4505941A: Lauter Tun For The Filtration Of Wort During Brewing

Today in 1985, US Patent 4505941 A was issued, an invention of David W. Raines, for his “Lauter Tun For The Filtration Of Wort During Brewing.” Here’s the Abstract:

Lauter tuns are used for the filtration of wort during brewing. In use the wort runs off through a filter bed and has to be collected. Hitherto the bottom of such tuns have been flat having a number of holes through which the wort runs. If the bottom is ostensibly flat, problems can arise in that puddles accumulate in any undulations leading to possible spoilation of the wort. The bottom of a tun in accordance with the invention is formed with a series of straight parallel valleys extending across the tun and having spaced wort collection points for connection to straight wort mains or manifolds located beneath the tun.


Patent No. 2631777A: Process For Centrifugal Separation Of Yeast Cells From Beer

Today in 1953, US Patent 2631777 A was issued, an invention of Verner Hanno Tore, for his “Process For Centrifugal Separation Of Yeast Cells From Beer.” There’s no Abstract,
but the description claims that the “invention relates to the centrifugal separation of impurities from liquids, such as the separation of yeast cells from beer. More particularly, it relates to an improved process for this purpose, whereby contamination of the centrifugally purified liquid by the impurities, incident to interruption of the centrifugal separation, is avoided.”

Patent No. 1132218A: Bottle-Filling Machine

Today in 1977, US Patent 1132218 A was issued, an invention of Adolph Schneider, for his “Bottle-Filling Machine.” There’s no Abstract, but the description states that the “present invention relates to that type of mechanism used for the purpose of packaging carbonated liquids, or analogous substances, under pressure:”

The objects of the present invention are, to provide a stationary support upon which the to-be filled packages rest during the filling operation; to provide a series of pistons, one of which will actuate the filling tube of the bottle filling mechanism, and the other or. which will actuate the sealing head; to provide a series of cylinders for said pistons, one piston being contained in each cylinder; to arrange system of pressure supply ducts for conveying pressure to said cylinders for the purpose of actuating the pistons; to arrange a series of ducts for exhausting the pressure from the said cylinder so arrange these ducts, if desired, as to enable them to perform double functions, namely, that of an inlet and an exhaust duct; to provide an automatically operated valve for controlling the flow of liquid from the source of liquid supply to the filling tube, and in arranging this valve so that it is automatically operated at a time approximately when the filling tube has reached its lowermost position; to provide a method of establishing communication between a source of air pressure less than the sure of the liquid in the tank and the liquid of the bottle; to provide a valve for controlling the flow of said air whereby said valve will be automatically operated to establish said air communication at practically the same time that the communication is established to permit the flow of liquid from the filling tube into the bottle; to provide an arrangement whereby one of the set of pistons may be power driven in both sections, and the other of said pistons can be power driven in one direction only, with the last mentioned piston being moved in the opposite direction by contact with the first mentioned piston; and to provide a telescopic connection between the source of liquid supply and the filling tube, and a telescopic connection between the source of air supply and the sealing head.

Patent No. 4011896A: Apparatus For Rapidly Dispensing Beer Into Open Cups

Today in 1977, US Patent 4011896 A was issued, an invention of John W. Nilon and Thomas J. King, for their “Apparatus for Rapidly Dispensing Beer into Open Cups.” Here’s the Abstract:

Beer is stored in vessels located in a refrigerated storage area before passing through dispensing lines connected to a plurality of dispensing taps. The dispensing lines are maintained in heat-exchanging relationship with cooling apparatus which further depresses the temperature of the beer below that of the refrigerated storage area. By the time the beer reaches the cooling taps, the temperature of the beer is sufficiently depressed so as to permit the beer to be dispensed at a high rate into drinking containers which pass beneath the taps.

Patent No. 4255457A: Method And Apparatus For Preventing Buckle Of Beer Cans During Pasteurization

Today in 1981, US Patent 4255457 A was issued, an invention of George J. Collias, assigned to the Kepros-Ganes Company, for his “Method and Apparatus for Preventing Buckle of Beer Cans During Pasteurization.” Here’s the Abstract:

A method is described for preventing buckling of beer-can tops and bottoms during pasteurization of the beer. Prior to the pasteurization, an anti-buckle ring is mated with each beer can such that the ring captures the base portion of the can’s bottom. The ring permits the bottom’s panel to bulge outwardly while preventing radial displacement of the bottom’s base area and, hence, buckling of the can bottom, when the heat applied during pasteurization causes the internal pressure of the can to increase. To prevent buckle of the beer can’s top, another anti-buckle ring may be mated with the top of the can such that the latter ring captures the double-seam area on the top of the can to prevent radial displacement at key points of the top. After pasteurization, both rings are automatically removed from the can for use with another can.
