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).

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.
