Patent No. 700833A: Manufacture Of Fermented Liquors

patent-logo
Today in 1902, US Patent 700833 A was issued, an invention of Joseph Schneible, for his “Manufacture of Fermented Liquors.” There’s no Abstract, though it’s described this way in the application:

This invention relates particularly to the carrying on of the fermentation of liquors such as malt beverages, for example and to the culture, propagation, and separation of yeast for further use As the fermentation of such liquors is now commonly practiced the yeast propagated for further use is separated and collected under conditions which are liable to result in contamination of the yeast by contact with air,usually teeming with wild ferments and very often with fungi, and in subsequent injury to the finished product.

It is the object of this invention to provide for the carrying on of the fermentation and the separation of the yeast in such a manner as to avoid exposure of either yeast or liquor to such contaminating and injurious influences, while at the same time the fermentation is carried on under practically normal conditions as to pressure.-

In accordance with this invention the newly-fermented liquor containing the yeast in suspension for further inoculation is transferred from the vessel in which the fermentation was carried on to a clean vessel, in which the separation of the yeast intended for further work from the liquor takes place and from which the liquor is withdrawn, thereby leaving the yeast in the clean vessel. The further quantity of liquor to be fermented is then introduced into the vessel containing the yeast and is inoculated thereby,thus avoiding altogether the removal of the yeast from the vessel in which the same has been allowed to separate from the fermented liquor and avoiding its exposure to the contaminating influences above referred to. This process is carried on successively in the manner referred to, the newly-fermented liquor being transferred from the vessel in which the inoculation has taken place and the main fermentation was carried on to a clean vessel, as before.

Patent No. 5906151A: Apparatus And Method For Brewing An Alcoholic Beverage

patent-logo
Today in 1999, US Patent 5906151 A was issued, an invention of Adam Firestone, Jeffers Richardson, Donald E. Othman, and Michel A. Blom, assigned to Firestone Walker, LLC, for their “Apparatus And Method For Brewing An Alcoholic Beverage and Beverage Brewed by Same.” Here’s the Abstract:

An apparatus for brewing an alcoholic beverage includes a plurality of wooden barrels including at least one first wooden barrel, at least one second wooden barrel, and at least one third wooden barrel; an enclosed trough; a plurality of first conduits providing flow communication between each of the plurality of wooden barrels and the enclosed trough; an enclosed catch pot in flow communication with the enclosed trough; a plurality of second conduits providing flow communication between the enclosed catch pot and each of the plurality of wooden barrels; and devices, such as valves, for controlling flow between each of the plurality of wooden barrels and the second conduit. The at least one first wooden barrel is a new barrel that has been filled with an alcoholic beverage up to 5 times, the at least one second wooden barrel is a middle aged barrel that has been filled with an alcoholic beverage from 6 to 12 times, and the at least one third wooden barrel is an old barrel that has been filled with an alcoholic beverage from 13 to 30 times.

This is essentially a patent for Firestone Walker’s modified Burton Union System that they pioneered when they first started, and then scaled-up when they bought the old SLO Brewery in Paso Robles and increased the size of their beer production. Jeffers, of course, is still there is the Barrelmeister, or Director of the Firestone Walker Barrelworks. That system is one of only two such brewing systems left in the world, the other being at Marston’s in Burton-on-Trent in England.

Patent No. 2420708A: Beer Meter

patent-logo
Today in 1947, US Patent 2420708 A was issued, an invention of Clifford S. Hutsell, for his “Beer Meter.” There’s no Abstract, though it’s described this way in the application:

To carry out the principles of my invention, the liquid is passed through a cooling coil which is immersed in some suitable cooling medium, the length of such cell can be varied so that the beer or other liquid can be passed through one loop or many loops of the coil; in this way the beer is brought under constriction in which its velocity is dissipated by frictional losses without the liquid itself being agitated. The liquid is then led through a discharge opening from which it may be drawn into a glass or other receptacle. This whole dispensing action is controlled, except for the adjustment of the length of coil used, by a single operating lever. My device will control the delivery of beer so that its included gas will be properly handled. The volume of the liquid is accurately measured. Each portion dispensed is accurately counted. The control and serving of beer on draught has always presented a difficult problem due to the beers susceptibility to the influence of three ever-present, variable factors; pressure, balance. Beer in its making is charged with carbon dioxide, the retention of such charge is essential to maintain its quality. When the beer is quiescent, at a sufficiently low temperature, the carbon dioxide is inert. This temperature is below the desirable serving temperatures and as the temperature is raised for serving there is a area sufficiently small to form a restriction to the temperature and agitation or tendency to discharge the carbon dioxide from the beer. To offset this tendency to dissipate its included gas and also to raise the beer to the discharge faucet, gas or air pressure is applied to the beer in the keg. The amount of pressure necessary to hold the carbon dioxide charge in the beer is in direct proportion to the tempera considerable degree, destroys the essential quality of the beer and in addition frequently causes excessive foaming at the faucet and a consequent wastage of beer.

A certain degree of refrigeration together with some form of constriction between the beer keg and the discharge tap would effect adequate control of the beer if the composition and condition of the beer were constant. However, no constant amount of restriction of the line is equally effective at all times because the beer may vary in its gaseous content, in its temperature, or it may have been recently agitated.

Patent No. 2348797A: Crown Cap Selecting Machine

patent-logo
Today in 1944, US Patent 2348797 A was issued, an invention of Louis A. Fischer, assigned to the Schaefer Brewing Co., for his “Crown Cap Selecting Machine.” There’s no Abstract, although in the description it includes this summary:

This invention relates to crown cap selecting machines, and has for its object to provide means for inspecting the interior of such machines while the same are running, and also provide means for preventing the caps from clogging during the operation of the machine.

In the use of such cap selecting machines, it frequently happens that inspection of the interior of the same becomes necessary and also that certain caps which have become clogged be removed. Also certain foreign matters must be dislodged.

This requires a shutting down of the machine and a re-starting, this requiring several hours of non-use of the machine.

The invention consists of a door closed opening which permits the caps to be ejected from the machine, capable of being opened and closed during the operation of the machine, and the invention also consists in the means for preventing clogging of caps.
