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.
