Description: |
Claim centers on the detachable cutting lip held in position by a pin in the body of the bit, a dovetailed recess and a screw.
A _Scientific American_ article (Vol. 10, Issue 37, May 26, 1855) about this patent claims a partial assignment to John W. Hawkes, Washington Market, NYC. It also describes this auger bit as potentially being of greatest value to ship's carpenters boring holes for trenails. |
