Description:
The claims include the combination of hinged jaws with triangular teeth, the "gum-band spring" and the handle. The sheller is rotated, while the hand holding the ear is stationary.

The specifications call this an improvement on the Patton & Middleton patent 99,106.

Two variant examples and an advertising flyer are shown in "The Hand Held Corn Sheller," by Jim Moffet. The form of the handle and sheller jaws as manufactured are echoed in design patent D70,218.
