This sheller is No. 5 in the book, Field Guide to Patented Hand Corn Shellers .
Pressure is applied to the jaws by two coil springs fitted on a pin through the jaws.
The jaws are shaped so as to pull the ear through the sheller as either the cob or the sheller is rotated. The design is extremely efficient, however, as with most hand shellers, the kernels fly in all direction when the tool is used vigorously. The wood handle shows substantial aging, but is still solid and safe to use. The iron and brass are in fine condition.
