Black American invention corn sheller

In 1884, Lackrum Blue, a black American inventor, was issued a patent for a “Hand Corn Shelling Device” (U.S. No. 298,937). It consisted of an oblong blade or plate of metal, such as cast-steel, having its shank formed with screw-holes, by which it can be secured to a bench, or any other suitable support. At the outer end it is formed with a semicircular, concave portion, the lower edge of which is slightly sharpened, and at its extreme outer end is a tooth or projection. The tooth would assist in the removal of two rows of grain when an ear is started for shelling. The ear is then placed in and turned around and against the concave knife-edged portion, and the remaining grain is thus shelled off rapidly.«
