Today in 1907, US Patent 860390 A was issued, an invention of George Edward Laubenheimer, for his “Hop-Jack.” There’s no Abstract, although in the description it includes this summary:
The Object of this invention is to provide a hop jack in which the screen or strainer is so constructed that the wort quickly drains oh and the hops are quickly and, thoroughly sparged and removed from the greater portion of the surface of the screen by mechanical means, thereby obviating n great deal of the manual lahoi’ usually required where a lalsc bottom is employed.
