patent-logo
Today in 1865, US Patent 48791 A was issued, an invention of Justus Chollae, for his “Improved Cooler For Beer and Other Liquids.” There’s no Abstract, although in the description it includes this summary:

Our invention consists in a peculiar construction and arrangement of portable cooler for beer, cider, and other liquids.

In the construction of our improved cooler a common Water-bucket or other suitable vessel A may be used to receive the cooler proper, B,which consists of an annular chamber nearly fitting the bucket. This annular chamber B is made of galvanized iron or other suitable material. It has a large central space, C, into which the ice is placed for cooling the beer or other liquid. This chamber B is closed at top and bottom, so that the beer is not exposed to the atmosphere, and may be kept under pressure, if desirable.

The beer or other liquid is admitted to the cooler through a tube, D, which is most conveniently made of india-rubber. The stop-cock E is to be inserted into a barrel or other vessel from which the beer or other liquid is to be drawn. A tube, F, extends from the top to near the bottom of the cooler B, and is provided with a stop-cock, G, for the discharge of the beer or other liquid drectly from the bottom of the cooler. The lower end of this tube is perforated with small holes, or otherwise provided with a suitable strainer

Today in 1944, US Patent 2354093 A was issued, an invention of Berthold Stein, for his “Brewing Apparatus.” There’s no Abstract, although in the description it includes this summary:

The present invention relates to brewing apparatus, more especially adapted for the achievement of certain improvements in the art of brewing beer, ale, near beer, or the like, with the principal object of making a more palatable and stable malt liquor, because a decided need exists for such improvement, inasmuch as a great many people do not. like to drink the present malt liquor of such general class particularly because of the unpalatable taste or odor.

Also, today in the same year, US Patent 2354092 A was issued, another invention of Berthold Stein, for his “Art of brewing beer, ale, or near-beer.” There’s no Abstract, although in the description it includes this summary:

The present invention relates to certain improvements in the art of brewing beer, ale, near beer, or the like, with the principal object of making a more palatable and stable malt liquor, because a decided need exists for such improvement, inasmuch as a great many people do not like to drink the present malt liquor of such general class particularly because of the taste unpalatable or odor.

The drawing file with this patent looks virtually identical to the other one, too.

patent-logo
Today in 1980, US Patent 4212950 A was issued, an invention of Robert P. Adams, assigned to The Virtis Company, Inc., for his “Fermenting Apparatus.” Here’s the Abstract:

Apparatus providing for the growth of cells in a nutrient bath under controlled conditions includes a pressure vessel with a surrounding dimpled jacket. The pressure vessel is adjustably mounted on three vertical mounting columns, from which it is thermally isolated. Temperature control for the pressure vessel is achieved by a closed heat transfer system which includes a pair of heat exchanger sections in series, one for heating and one for cooling the heat transfer fluid. A removable head or lid for the pressure vessel is lifted by three cables running through a common pulley mounted above the pressure vessel. Impeller blades for agitating the contents of the fermenting apparatus have a drive shaft that extends through the head and is connected to a gear box by a removable driving link. The gear box, and an associated drive motor, are affixed to a common mounting bracket that is pivotable to permit maximum displacement of the head.
