June 30, 2016 By Jay Brooks

Today in 1903, US Patent 2085186 A was issued, an invention of Jacob Frederic Wittemann, for his beer “Filter.” There’s no Abstract, although in the description it includes this summary:

My invention relates to improvements in filters or filtering-presses designed particularly for use in filtering beer and the like. In devices of this nature it is the general aim to provide as large a filtering-surface as possible, and this is usually done by multiplying Heretofore each element has generally consisted of several separate parts which must be assembled and also separately handled when it is desired to change the filter, as by substituting a fresh filtering mass and adding new elements.

The objects of the present invention are to produce a filter composed of interchangeable elements all the parts of each of which are combined in one fixed construction and to so construct these elements that when assembled the beer or other fluid to be filtered has ready ingress to and egress from the filter, while the air, water, or other foreign matter in the filter is readily discharged.
