Today in 1889, US Patent 410994 A was issued, an invention of Charles Sommer, for his “Stave Dressing Machine.” There’s no Abstract, although in the description it includes these claims:

My invention relates to improvements in that class of machines by which staves used in the manufacture of cooperage, such as beer kegs, barrels, etc. are dressed. Its object is to dress the staves on both sides at once, giving them at the same time the desired curve corresponding with the curve of the keg or barrel and providing at the two ends additional thickness, allowing depth for the croze.

patent-logo
Today in 1902, US Patent 708942 A was issued, an invention of Harry Torchiani, for his “Apparatus For Racking Off Beer.” There’s no Abstract, although in the description it includes these claims:

My invention relates to apparatus for filling barrels, kegs, or the like with fermented liquids, such as beer; and one of the objects of the invention is to collect the foam that arises in a barrel or keg being charged and prevent it from passing into another barrel or keg that is being charged; and another object of the invention is to provide improved means for firmly connecting the racking-off faucet with a barrel or keg and for readily disconnecting it therefrom; and to these ends my invention comprises the novel details of improvement that Will be more fully hereinafter set forth, and then pointed out in the claims.

Patent No. DE2808712A1: Plant To Manufacture Beer Wort By Hydrating Crushed Malt

By

patent-logo
Today in 1979, US Patent DE 2808712 A1 was issued, an invention of Simon Redl, assigned to Anton Steinecker Maschinenfabrik, for his “Plant to Manufacture Beer Wort by Hydrating Crushed Malt — Introduces Water as Unbroken Film to Avoid Aeration of Product.” Here’s the Abstract:

The installation comprises a pressure roll mill for wet crushing brewers malt into a wort mixing chamber where a hydrator introduces additional water and an agitator mixes the milled malt and water. The hydrator is designed to introduce water in the form of a continuous, film which runs down a guiding surface extending into the wort mix. The guiding surface pref. extends alongside or beneath and for the full axial length of the mill rolls. The guiding surface is a side wall of the casing which forms the chamber containing the mill rolls and the agitator. Both walls are pref. employed as guiding surfaces. Water is pref. run on to the guiding surface from an adjustable width slot at the bottom of a supply pocket. The guiding surface pref. form one edge of the slot which has a width of 0.5-5.0., (1.5-3.0) mm. The hydrator offers faster and more homogeneous mixing in of water than single exit water inspectors. Undesirable aeration of the wort is held to an absolute minimum which was not possible with spray injectors.

Patent No. 566898A: Racking Apparatus For Barreling Beer

By

patent-logo
Today in 1896, US Patent 566898 A was issued, an invention of Alfred E. Peroe, for his “Racking Apparatus for Barreling Beer.” There’s no Abstract, although in the description it includes these claims:

My invention relates to what is termed “racking apparatus” used for barreling beer or fermented liquors under pressure and my improvements upon this class of devices relate to a method of constructing them by which the air or gas escaping from the barrel as replaced by the entering beer or liquor will be conducted from the barrel, so as not to interfere with or impinge upon the entering beer or liquor.

Patent No. WO2008101298A1: Brewing Apparatus And Method

By

patent-logo
Today in 2008, US Patent WO 2008101298 A1 was issued, an invention of Allan K. Wallace, assigned to Coopers Brewery Limited, for his “Brewing Apparatus and Method.” Here’s the Abstract:

The specification discloses brewing apparatus and a method for testing for end of fermentation of a fermenting brew. It has been determined that, once fermentation is complete, the temperature of a brew (such as beer) shows a tendency to stratify in horizontal layers. However, the activity of fermentation disrupts the tendency of the brew to stratify. Accordingly, the brewing apparatus comprises at least two temperature sensors positioned to measure a temperature difference between the temperature at a first height of the brew and the temperature at a second height of the brew. End of fermentation is identified if the temperature difference is greater than a threshold difference.

Patent No. 864560A: Keg Sprinkling Machine

By

patent-logo
Today in 1907, US Patent 864560 A was issued, an invention of Otto L. R. Ritter, for his “Keg Sprinkling Machine.” There’s no Abstract, although in the description it includes these claims:

This invention relates to sprinkling machines for sprinkling kegs, barrels, bottles, jars and analogous articles.

The invention primarily contemplates a machine provided with a rotatable and disappearing nozzle for applying the cleansing medium, the latter actuating the nozzle when supplied to wash or rinse an article gravity when the cleansing medium supply is cut off, thereby permitting the article to be readily removed after it has been washed or rinsed without in the least damaging the nozzle.

The invention further contemplates a machine provided with a support for the article to be washed or rinsed, said support being capable of rotation upon a vertical axis, and provided-with means for opening a hot or cold cleansing medium supply. The nozzle by its rotation projects the cleansing medium outwardly in all directions, and it is thus rendered more effective in treating a greater surface area of the article cleansed. The movement of the nozzle is rendered easy and Without obstruction when rotated by providing a ball bearing therefor, all of which will be more fully hereinafter set forth.

Patent No. 20110206487A1: Keg Handling Equipment

By

patent-logo
Today in 2011, US Patent 20110206487 A1 was issued, an invention of Terry George Morgan, for his “Keg Handling Equipment.” Here’s the Abstract:

A keg conveying trolley has a pair of wheels, a central post and a slide which carries a hook for grasping the keg rim. The slide is lockable at different keg heights. A foot plate assists in tipping the trolley to an inclined position for wheeling the keg from one place to another. The keg stacking version has a winch worked by hand or a cordless drill. The keg is supported by a rise and fall carriage. The carriage can be modified to be multitask. Variants can lift gas bottles on their side, truck tires for placing on wheel studs and odd shaped loads.

By

patent-logo
Today in 1972, US Patent 3685508 A was issued, an invention of Le Roy W. Heilmann, for his “Tank Construction.” Here’s the Abstract:

A tank bottom having spaced inner and outer members, said inner member being made of relatively thin material having good heat transfer, said spaced inner and outer members forming part of a pressure chamber for heating the contents of said tank, said pressure chamber being subjected to relatively high pressures and temperatures, said inner bottom having strengthening means connected to the outer surface thereof, said strengthening means not being connected to said outer member, said inner member being strong enough to hold the contents of the tank but not strong enough to withstand the cyclical pressures within the pressure chamber over a period of use without said strengthening means.
