Patent No. 1015443A: Apparatus For Macerating Wort

By

patent-logo
Today in 1912, US Patent 1015443 A was issued, an invention of Robert Hoffmann, for his “Apparatus for Macerating Wort.” There’s no Abstract, but in the description he explains the problem and his solution:

In macerating they wort in making beer the sparging water has hitherto been poured on to the wort by means of a rotary sprayer spraying over or sparging the wort. As the sparging water falls from a certain height on to the surface of the wort it is not only impossible to avoid unintentionally mixing the wort with the sparging water,’but the latter is also undesirably cooled. Both disadvantages thus involve a loss of yield from the grain and thus mean an incomplete’ working.

Now as compared with the ordinary apparatus for maceration this invention consists in the sparging water not being, allowed to fall from a height on to the surface of the wort but being introduced in layers on to the surface of the wort, so that the grain during maceration is slowly compressed by the sparging water and does not mix therewith.

This improved apparatus consists in other’ words in the sparging water being allowed to flow on to the wort in a continuous stream without first having to fall through the air — on to the surface of the wort.

Patent No. 4494451A: Brewing Apparatus

By

patent-logo
Today in 1985, US Patent 4494451 A was issued, an invention of John F. Hickey, for his “Brewing Apparatus.” Here’s the Abstract:

Brewing apparatus which comprises a first vessel including heating means, a second vessel including strainer means, a third vessel, and a valve means and pump arrangement by means of which the three vessels can be coupled as necessary for fluid transfer purposes so that the first vessel can be used firstly as a hot liquor tank to produce hot liquor which is transferred to the third vessel which serves firstly as a hot liquor container, from which in use the hot liquor is transferred to the second vessel wherein it is mashed with malt to produce a wort and which serves firstly as a mash tun, from which the wort is transferred to the first vessel therein to be heated with hops whereby the first vessel serves secondly as a brewing kettle from which the resultant brew is transferred to the third vessel which serves secondly as a fermenting vessel.

Patent No. 2393518A: Fermentation Of Beer

By

patent-logo
Today in 1946, US Patent 2393518 A was issued, an invention of Stephen T. Clarke, for his “Fermentation Of Beer.” There’s no Abstract, but the description explains that the “object of the invention is to provide’a process and apparatus of the top fermentation type which will produce a very full drinking beer of high stability and character.” It continues:

The whole process of fermentation is carried out under pressure in a single enclosed vessel having at the top thereof a detachable cone or dome provided with an outlet pipe of small diameter terminating in a device such as a nipple for controlling the pressure. The outlet of the pipe is at or near the top of an enclosed yeast-back provided with a cock or valve which normally is open to the atmosphere to relieve pressure in the yeast-back. The yeast-back is also provided with a draining tube for returning the yeast drainings to the fermenting vessel.

Patent No. 2414669A: Art Of Brewing

By

patent-logo
Today in 1947, US Patent 2414669 A was issued, an invention of Gustave T. Reich, for his “Art of Brewing.” There’s no Abstract, but the description explains that the “invention relates to a continuous process of brewing beer from malt and cereal. Among its objectives are the securing of the maximum diastatic action in the minimum time thus permitting advantageous continuous saccharincation, the preventing of the destruction of the diastase and peptase by heat prior to the sacchariflcation of the mash so that the full effect of all the diastase is released in the sacoharifying step, the effecting of the maximum digestion of the malt by the peptase largely prior to the saccharibody of the hulls is not fication, the avoiding of dissolving objectionable soluble materials found in the malt hulls by digesting the malt while the hulls are largely intact.”

Patent No. 553269A: Method Of Manufacturing Beer Or Ale

By

patent-logo
Today in 1896, US Patent 553269 A was issued, an invention of Gustave Sobotka and Adolph Kliemetschek, for their “Method of Manufacturing Beer or Ale.” There’s no Abstract, but the description explains that the “invention relates to methods of manufacturing beer and ale, and the objects are mainly to provide an improved process whereby a superior quality of beer or ale may be produced and in a much shorter time than is required when made according to methods heretofore in use, thereby effecting a saving of both time and labor, and also to avoid the loss of the aromatic principle or constituents of the hops, which necessarily results from ordinary methods of boiling the hops with the Wort in the copper, and further to reduce the quantity of hops usually required for the manufacture of a given quantity of beer or ale by utilizing the flavoring, disinfecting, and preserving qualities of the hops to better advantage, and thereby also effect a saving of material.”

Patent No. 2028283A: Foam Controlling Beer Faucet

By

patent-logo
Today in 1936, US Patent 2028283 A was issued, an invention of Jules Howard and Sanford E. Richeson, for their “Foam Controlling Beer Faucet.” There’s no Abstract, but the description explains that the “invention relates to beer and like taps or valves for drawing off foamy liquid from a cooler or other container.” It was designed “to prevent loss of the liquid incident to foaming in the glass after standing for some time in the cooler or container, and at the same time to regulate the depth of the head or cap of foam at the top of the glass.”

Patent No. 3933282A: Universal Tavern Unit For Keg Tapping Device

By

patent-logo
Today in 1976, US Patent 3933282 A was issued, an invention of Frederick F. Stevens, Jr., and assigned to Hoff-Stevens, Inc., for his “Universal Tavern Unit for Keg Tapping Device.” Here’s the Abstract:

A universal tavern unit for a keg tapping device comprises a basic tavern unit for connection to a keg unit permanently or semi-permanently connected to a keg. The basic tavern unit is adapted to cooperate with the keg unit to provide inlet and outlet passageways which communicate with the interior of the keg for the introduction of gas under pressure into the keg and the discharge of beer or other liquid therefrom. The universal tavern unit further includes a pressure relief check valve adaptor assembly for connection to the basic tavern unit to adapt it to the requirements of an associated beer or liquid distribution system.

Today in 1915, US Patent 1125735 A was issued, an invention of Frank A. Schaum and Eugene F. Wales, for their “Keg or Container.” There’s no Abstract, but the description explains that the “invention relates to kegs or other containers and has for its object reinforcing devices for strengthening the container.” They continue. “A further improvement is devices for holding the hoops in place. These devices may be made part of the reinforcing structure.”

Patent No. 4720076A: For A Carbon Dioxide Gas Pressure Dispense System For Beer

By

patent-logo
Today in 1988, US Patent 4720076 A was issued, an invention of Roger J. Hyde, for his “Carbon Dioxide Gas Pressure Dispense System for Beer.” Here’s the Abstract:

A dispense tape (10) to control the flow of carbonated beers is configured to minimize pressure drop and turbulence in beer flow to an outlet nozzle (14) when open, the tap having flow restrictor means (52) operatively connected as a downstream extension of the tap valve (30), located in the path of beer flowing from the valve, arranged only to affect beer flow when the tap is nearly closed and configured to substantially restrict beer flow to maximize pressure drop and turbulence; choice of nozzle length/bore ratio enabling either a creamy flow or a squib of beer to be dispensed.
