Patent No. 1299379A: Wild-Oat And Barley Separator

Today in 1919, US Patent 1299379 A was issued, an invention of Robert J. Owens, for his “Wild-Oat and Barley Separator.” There’s no Abstract, although in the description it includes this summary:

The object of my invention is to provide a separator which will dispense entirely with fans and air currents and wire sieves and of such devices as flannels, carpets and the like, frequently found in machines of this type for separating and grading grains.

A further object is to provide a machine by means of which not only wild oats but small, imperfect kernels of grain can be separated from the full, plump kernels that are suitable for seed.


Patent No. 2633251A: Palletizer

Today in 1953, US Patent 2633251 A was issued, an invention of John K. Bruce, for his “Palletizer.” There’s no Abstract, although in the description it includes this summary:

My invention provides a completely automatic machine for loading pallets. Empty pallets may be fed into one end of the machine, and cartons or boxes fed in from the side and loaded pallets may be delivered out the other end. Not only does my palletizer accurately layer and stack the cartons and boxes, but in addition arranges non-cubic boxes in any selected pattern so that the boxes of different layers will interlock or overlap and provide a stable and rigid stack on the pallet.


Patent No. 2035962A: Brew Kettle

Today in 1936, US Patent 2035962 A was issued, an invention of Alvin Hock, for his “Brew Kettle.” There’s no Abstract, although in the description it includes this summary:

My invention consists in providing a closed kettle or receptacle preferably having a downwardly converging bottom provided with a central outlet therein and having above said bottom a series of U-tubes extending into and out of the kettle and connected to steam inlet and exhaust outlet tubes whereby steam will circulate through said U-tubes which are immersed in the liquid and whereby heat is given off to said liquid from the entire surface of said tubes, so that all of the heat thus transferred is fully utilized.


Patent No. DE3235563A1: Siphon Bottle Filling Apparatus

Today in 1984, US Patent DE 3235563 A1 was issued, an invention of Karl Horst Knopf, for his “Siphon Bottle Filling Apparatus.” Here’s the Abstract:

Traditional German siphon bottles are for the most part filled at the publican’s beer dispensing tap. In order to make possible filling without foaming and release of carbon dioxide, according to the invention a filling closure has been created which allows the bottle, prior to filling, to be put under pressure by means of a hand pump attached to the filling closure. No foam can form as the beer flows in, since the beer enters under counter-pressure and cannot expand. To regulate further overpressure building up as the beer flows in, a vent screw is provided.


Patent No. 1177117A: Method Of Preparing Beer

Today in 1916, US Patent 1177117 A was issued, an invention of Oscar M. Lamsens, for his “Method of Preparing Beer.” There’s no Abstract, although in the description it includes this summary:

In beers which are brewed in the ordinary w manner, there is a’tendency to cloud or become turbid when they are chilled; specifically after pasteurization. Such beer or beer that has been bottled for sometime and is consequently in such condition otherwise as to become clouded when chilled, is found on examination to contain coagulated albuminoids. In other words the albuminoids that are ordinarily carried in the beer in such condition as to be invisible, become coagulated when the beer is reduced in temperature. and so impair the brilliancy and clearness of the liquor.

This invention relates to the preparation of beers and ales, and more particularly beers for bottling, whereby the product possesses great stability and does not tend to become clouded or turbid. even when chilled to a considerably lower than normal temperature, the liquor in fact being what lazily be termed chill proof beer or the According to the method herein described, advantage is taken of the fact that the yeast which is present in greater or less quantities in the beer before it has been thoroughly settled, carries or contains proteolytic enzymes but in such manner because of the organization or structure of the yeast cells that the class of albuminoids in beer which 40 tend to become coagulated; under reduction of temperature, do not get into contact with the enzymes and are not affected thereby;


Patent No. 4112: A New Or Improved Method Of Drying And Preparation Of Malt

Today in 1817, British Patent 4112 was issued, an invention of Daniel Wheeler, for his “A New or Improved Method of Drying and Preparation of Malt.” According to one account, “Black patent malt changed the game in beer history, as it allowed darker beers to be brewed without the use of adjuncts that would adulterate said brew. By 1828, Guinness had replaced their entire stock of brown malt with black patent malt, and their own stout porter started eliciting competition from other notable breweries such as Beamish, Crawford, and Murphy’s.”

Here’s a short description of his patent, from an 1881 book, “Abridgments of Specifications Relating to Brewing, Wine-Making, and Distilling Alcoholic Liquids.”


Here’s more of the background to Wheeler’s patent, from Ron Pattinson, in a post entitled Patent malt in the early 19th century:

When all forms of colouring were made illegal in 1816, Porter brewers had a big problem. How could they brew a beer of the right colour when using mostly pale malt? The answer was provided by Daniel Wheeler, who, by roasting malt in a way similar to coffee beans, created a malt capable of colouring a large quantity of wort. Pale malt was roasted at 360 to 400º F in metal cylinders, which revolved over a furnace. (Source: “The Theory and Practice of Brewing” by W.L. Tizard, London, 1846, page 90.) Wheeler acquired a patent for the process, hence the name patent malt. It was also known as black malt, porter malt or roast malt.


And here’s another account of his patent, and its effect on the history of brewing.

In 1817, Daniel Wheeler obtained British Patent No. 4112 for a “New or Improved Method of Drying and Preparation of Malt.” His invention of the Drum Malt Roaster allowed maltsters to roast malt to the point where a small amount of malt could darken a large amount of beer without imparting an overly burnt or tarry taste to the entire brew. Before Wheeler’s invention, brown ales were made exclusively from brown malt, but the advances in kilning technology gave way to the use of pale malts, which became a cheaper and more reliable alternative. Therefore, the color and flavor profiles of brown ales were subsequently determined more by modern style dark malts, crystal malts and caramelized sugars.

And one more, partially from H.S. Corran’s A History of Brewing:

The malt bill is a combination of new and old but truly british malts (minus the 6-row). Black Patent Malt leading the way to the creation and evolution of porters by helping differentiate it from brown ales. From H.S. Corran’s A History of Brewing (1975), “On March 28, 1817, he obtained British Patent No. 4112 for “A New or Improved Method of Drying and Preparation of Malt. The adoption of malt made according to Wheeler’s patent, and called ‘patent malt,’ marked the beginning of the history of porter and stout as we know it today, and put an end to the period during which the term ‘porter’ was probably applied to any brown beer to distinguish it from pale ale. The new process was effective, economical, produced a palatable product and freed brewers from charges of adulteration. It was quickly taken up throughout the British brewing industry. Whitbread’s Brewery recorded stocks of Patent Malt in 1817, as did Barclay’s in 1820, and Truman’s showed stocks of ‘Black Malt’ in 1826.”

Patent No. 1995814A: Steam Boiler

Today in 1935, US Patent 1995814 A was issued, an invention of Thomas J. Parker, for his “Steam Boiler.” There’s no Abstract, although in the description it includes this summary:

This invention relates to boilers and more particularly to electrically heated boilers for generating steam. The boiler herein shown and described is a miniature boiler particularly adapted for generating steam for cleansing and sterilizing fluid conduits, such as beer coils, but obviously the invention may be applied to various uses requiring steam under pressure.

One of the objects of the invention is to provide a boiler in which steam of desired pressure may be quickly and efficiently generated. Another object is to provide for heating the water in the boiler to generate steam by means of a novel and very efficient electric heating element mounted in direct heat contact on and surrounding a generating cylinder which is part of the circulatory system of the boiler.
