Today in 1903, US Patent 724100 A was issued, an invention of Max Henius, for his “Wort-Separator.” There’s no Abstract, but in the description claims that the “object is to provide a wort-separator of novel as well as comparatively simple and inexpensive construction, whereby the filtration of wort, both from grains and hops, may be effected more thoroughly and with greater economy both of time and labor than by any other filtering means hitherto employed and of which I am aware.”
