Description: |
Improvements to patent 31,257, issued to N. F. Newell on 1861-01-29. The assignee partnership, Dodge & Wellington, was a wrench manufacturer. An ad in the 1867-10-26 Scientific American says that Dodge & Wellington were "sold proprietors and manufacturers" of "Jillson's patent animal trap", but we could not find any evidence that they manufactured this chuck. |
