Patent No. 409056A: Water Coil Boiler

Today in 1889, US Patent 409056 A was issued, an invention of Everett D. Moore, for his “Water Coil Boiler.” There’s no Abstract, although in the description it includes these claims:

The object of my invention is to provide an effective and convenient means for steaming, flushing, and thoroughly cleansing the pipes that are frequently employed for conducting stood that I do not confine myself to a burner beer, wines, and other liquids from a keg, of any particular form of construction. barrel, or other source from a keg, barrel, or other source to the tap or faucet of a beverage-drawing apparatus, which pipes are liable to become fouled and internally coated with sediment from the liquors or beverages passed through them, especially when standing therein over night. The impurities that are thus deposited in the pipes of a beverage-drawing apparatus are liable to taint a series of perforations 12 for the exit of gas. the liquor and are often injurious to health.

Heretofore the pipes of a beverage-drawing apparatus have been cleansed to some extent by forcing through them solutions of potash, lime, and other substances, which, however, are liable themselves to form injurious compounds in the pipes. My invention obviates these difficulties by providing a means for thoroughly cleansing the pipes with steam and hot water, as hereinafter described.


Patent No. RE10509E: Mash Cooler

Today in 1884, US Patent RE10509 E was issued, an invention of Frederick O. Kunz, for his “Mash Cooler.” There’s no Abstract, although in the description it includes these claims:

This invention relates to an apparatus for cooling mash to the fermentation temperature, which is simple in construction, effective in operation, and capable of being thoroughly cleaned with facility. The apparatus comprises a vertical column or chamber, which is traversed by a series of water conducting pipes, and is provided with detachable outer walls and doors for gaining access into the interior of the column and the tubes, for cleaning and other purposes. The water-tubes extend through the shell of the vertical column and lead into small non-communicating chambers formed between the shell of the cooler and the outer walls. The object of these chambers is to cause the water circulating through the tubes in an upward 0 direction to take a circuitous or zigzag course and flow out at the top of the cooler. The mash to be cooled flows into the cooler at the top thereof, and is strained and thrown down over the pipes in the form of a shower, and it makes its exit at the bottom of the cooler and passes through a vertical stand-pipe and escapes at the top of the latter, being then of a temperature suitable for immediate fermentation in the customary fermenters.

Patent No. 1969643A: Beer Cooling And Dispensing Apparatus

Today in 1934, US Patent 1969643 A was issued, an invention of Gottfried Fuchs and Hermann Spath, for their “Beer Cooling and Dispensing Apparatus.” There’s no Abstract, although in the description it includes these claims:

This invention relates toan automatic cooling and pressure plant for beer conduits and cold storage rooms with employment of frozen carbon dioxide.

It is already known, to employ frozen carbon dioxide for cooling chill rooms. These plants, however, are open to the objection that the carbon dioxide becomes lost as soon as it is no longer frozen. This circumstance renders very l0 questionable the economy of this cooling method, because, as is known, carbon dioxide is very expensive.

The invention relates to a plant, in which the gaseous carbon dioxide liberated by evaporation cools the chill room and also the beer conduit in the tapping device and at the same time serves as pressure medium for the beer in the barrel. ‘The dry ice is accommodated in the cold storage room in a. receptacle with insulated walls, from which go vessel the gaseous carbon dioxide liberated by evaporation is conducted into the beer conduit cylinder through a cooling pipe conduit extending through the cold storage room. The beer conduit cylinder is surrounded by a jacket accommodating the cooling water. The gaseous carbon dioxide is conducted-as pressure medium from the beer conduit cylinder in to the barrel. Posterior the receptacle accommodating the dry ice and anterior the cooling pipe conduit a known thermostat is arranged, by means of which the passage from the ice receptacle to the cooling pipe conduit is automatically regulated.

The jacket of the beer conduit is surrounded by a further jacket, the internal space of which is filled with cooling water which, owing to the expansion of the carbon dioxide in the cylinder, is cooled to freezing point, so that an ice jacket is formed around the beer conduit. The ice jacket is surrounded by a further jacket the internal space of which is filled with cooling water in order to protect the ice jacket against the external heat.

By means of this plant the dry ice is employed for three purposes, i.e. to cool the cold storage room and the beer conduit and to place under pressure the beer conduit, so that the dry ice is utilized in the most economical manner.


Patent No. 655330A: Hop Bleaching And Drying Kiln

Today in 1900, US Patent 655330 A was issued, an invention of James Dowdell and Arthur B.C. Dowdell, for their “Hop Bleaching and Drying Kiln.” There’s no Abstract, although in the description it includes these claims:

Our invention relates to a means for bleaching and drying hops or other material.

It consists, essentially, of a room or compartment having a foraminous floor adapted to support the hops to be dried and in conjunction therewith a covering which may be drawn over the surface of the hops to confine and prevent heat and moisture from escaping therefrom during the process of bleaching. The sulfur fumes produced in any usual or suitable manner are caused to rise into the hops and are there retained until the bleaching is perfected, after which the covering may be removed, and heat being applied the drying will be completed.


Patent No. 1034557A: Beer Spraying Device

Today in 1912, US Patent 1034557 A was issued, an invention of Max Adamowski, for his “Beer Spraying Device.” There’s no Abstract, although in the description it includes these claims:

My invention relates to improvement-s in spraying devices for faucets and more specifically to devices of this character especially designed for use in beer faucets. a

Ordinarily spraying of beer at the faucet as it is drawn is not desired since such spraying results in the formation of foam. However, Where a large bucket or can trade is carried on this spraying to facilitate the formation of foam is desired since the buckets or cans brought by the purchasers are of greater capacity than the amount which is purchased. The bartender in catering to this class of trade is desirous of filling the can or bucket irrespective of the size thereof for-.the amount tendered. This being so the object in forming a large amount of foam in the top of the can or bucket is obvious.

The object of my invention then is the production of the spraying device of the character mentioned, which will be effective in the formation of foam in the receptacle into which the liquid or beer is disposed, and further, a spraying device which will be of simple and economical construction, hence of low cost to manufacture.

Today in 1880, US Patent 230815 A was issued, an invention of Alvin D. Puffer, for his “Beer Cooler.” There’s no Abstract, although in the description it includes these claims:

This invention relates to improvements in a class of apparatus for reducing the temperature of soda-water or other liquids manufactured by myself, and shown and described in Letters Patent of the United States issued to me on the 6th day of December, 1870, and the 3d day of April, 1877, respectively, the purpose of the invention shown in the first-named patent being to economize the waste of ice used in cooling liquids; and it consists, primarily, in conducting the liquid to be refrigerated through a preliminary or auxiliary series or coil of pipes or cylinders situated within the ice-water which accumulates from the melting of the ice with which the primary cylinders or coolers are packed, or otherwise taking advantage of the low degree of temperature of such ice water to reduce the temperature of the soda water or other liquid previous to its entering the primary coolers, which receive cold directly from the ice, while the invention embraced in the second-named patent consists in a new or peculiar manner of conducting ,soda water through a cooler or refrigerating apparatus, the purpose of the invention being to thoroughly and effectually carry or force the water, in its passage through a series of cooling-cylinders, against the refrigerated sides or inner surfaces of such cylinders, or to prevent the formation of a central or inner current through the body of water in such cylinders.


Patent No. 6769981B1: Hop Vine Processor

Today in 2004, US Patent 6769981 B1 was issued, an invention of Kenneth J. Perrault and Charles J. Perrault, for their “Hop Vine Processor.” Here’s the Abstract:

A method and apparatus for the processing of hop vines. An automated hop processor cuts bulk-harvested hop vines into manageable segments with a minimum of handling operations. The bulk of hop vines are off-loaded onto an in-feed conveyor by positioning a transport on the in-feed conveyor. After verifying proper position of the transport a fork can be inserted into the transport. The transport is moved off of the in-feed conveyor and the fork removed from the bulk of hop vines. The Hop vines are then moved on the in-feed conveyor to a cutter, after verifying the transport is clear of the in-feed conveyor. The in-feed conveyor is stopped when the hop vines are in position for cutting and the hops are cut with a cutting mechanism. The cut hop vines are then conveyed to a shredder for shredding and further processing into component hop cones and hop vine silage.
