Patent No. 2847309A: Brewing Process

By

patent-logo
Today in 1958, US Patent 2847309 A was issued, an invention of Harold Howard Rohrbeck, assigned to the Olympia Brewing Company, for his “Brewing Process.” There’s no Abstract, although in the description it includes this summary:

Heretofore, in the conventional brewing process, it has taken considerable time toV filter the wort through the lautering bed provided by the grain in the lauter tub and also to sparge the bed. I believe the reason for this is that the lines, which are microscopic glutinous protein matter, have collected in the interstices of the filtering bed and have restricted and even completely closed them thus slowing down the filtering step.

It is a main object of the present invention to provide a brewing process overcoming the above disadvantage.

A further object of the present invention is to provide a process in which all or part of the fines are removed from the mash prior to the mash entering the lauter tub whereby to speed up the filtering operation.

A further object of the present invention is to provide an apparatus by which the method of the present invention may be carried out.

The process -of the present invention is characterized by the steps of separating the fines from at least a part of the mash prior to the mash being conducted to the lauter tub so that the filter bed is not nearly as congested or restricted by the presence of the fines as heretofore has been the case and thus the filtering action of the bed is much more rapid than heretofore.

Patent No. 1000086A: Straining-Tank

By

patent-logo
Today in 1911, US Patent 1000086 A was issued, an invention of Fred W Goetz and Claes Flodin, for their “Straining-Tank.” There’s no Abstract, although in the description it includes this summary:

Our invention relates, more particularly, to an improvement in tanks for straining hopped wort from the hops after the wort has been boiled with them for the requisite length of time in the brewing-kettles provided for the purpose.

In the process of brewing beer it is necessary, in order to prevent the beer from becoming bitter, to drain the wort from the hops as quickly as possible, after the boiling operation above referred to has been completed; and it is highly desirable that as much of the wort as is loosely held in the hops by absorption be drained 0H and recovered for further treatment.

One of our objects is to provide a construction of straining-tank which will enable the hopped wort to be quickly and effectively washed and drained from the hops and cause the latter to be freed, up to the maximum practical extent, of its wort-contents.

Another object is to provide a construction of straining-tank whereby the spent hops may be discharged therefrom in a simple and effective manner.

Patent No. 2757785A: Vertical Hop Picker Having Endless Carrier Chain For Hop Vines, Moving In A Vertical Plane

By

patent-logo
Today in 1956, US Patent 2757785 A was issued, an invention of Florian F. Dauenhauer, for his “Vertical Hop Picker Having Endless Carrier Chain for Hop Vines, Moving in a Vertical Plane.” There’s no Abstract, although in the description it includes this summary:

An object of my invention is to provide a vertical hop picker having endless carrier chain for hop vines, moving in a vertical plane, which is an improvement over the vertical hop picking machine shown in my copending application, Serial No. 179,722, filed August 16, 1950, and now Patent No. 2,677,378. In the copending case, I show an endless hop-carrying chain conveyor that has a portion for conveying hop vines between pairs of vertically movable hop picking fingers. The return portion of the endless hop-carrying chain that extends along the hop picking fingers, lies in the same horizontal plane as the portion that carries the vines between the picking lingers, but the return portion is spaced laterally therefrom. Moreover, I also disclose in the copending case, the endless hop-carrying chain as having an inclined portion extending from a hop vine feeding ‘platform up to the hop picking finger part of the machine. Here again, the return chain part passing along the inclined portion is spaced laterally from the inclined hop vine carrying portion. This necessitated the use of cam rails at the feed and discharge ends of the machine for opening the jaws of vine grippers, carried by the chain, for permitting an operator to attach vines to the grippers at the feed end and for automatically releasing the vines at the discharge end of the machine.

In the present case, the endless hop-carrying chain conveyor has both of its reaches lying in the same vertical plane. This causes the jaws of the vine grippers to open automatically at the discharge end of the machine and release the vines that have had their hops removed. The jaws remain in open position as the vine grippers travel from the discharge endV of the machine to the feed end. No cam rails are necessary at the feed and discharge ends of the machine.

A further object of my invention is to provide a device of the type described in which a swingable elevator boom is placed at the feed end of the machine for supporting the feed end of the carrier chain for hop vines. The boom can be swung so that its free end can be positioned adjacent to a hop vine carrying truck and this will permit an operator to unload hop vines one at a time, directly from the truck and attach `them to the vine grippers at the feed end of the machine. After the truck has been emptied, the boom can be swung to another truck and the vine unloading and attaching process continued. The unloading platform at the feed end of the machine may be dispensed with if desired.

Patent No. 206825A: Improvement In Beer-Pump Valves

By

patent-logo
Today in 1878, US Patent 206825 A was issued, an invention of John A. Prindle, for his “Improvement in Beer-Pump Valves.” There’s no Abstract, although in the description it includes this summary:

My invention relates to an apparatus for pumping fluids from casks, and is intended as an improvement on the device shown and described in Letters Patent No. 191,656, dated February 6, 1877, granted to Wm. F. Glass.

My improvement consists, principally, in the peculiar construction of the bung, provided with valve or valves, which close the bunghole hermetically and automatically by the pressure of gas from within, while air or gases may be easily forced through it into the cask, barrel, or other vessel.

It also consists in constructing the air valve proper of rubber or equivalent elastic material, forming it conical or conoidal, and causing it to rest upon a sharp-edged seat, whereby slight pressure will be sufficient to insure good results, and heavy pressure the same results, without liability of damaging the valve.
