Today in 1890, US Patent 428101 A was issued, an invention of John Irlbacker, for his “Apparatus For Extracting Hops.” There’s no Abstract, though it’s described this way in the application:
My present invention has general reference to improvements in hop-extractors; and it consists in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, and then pointed out in the claims.
