Description: |
| Double male-threaded "nut" parallel to the shank engages female threads on the inside of the handle ferule and the inside of the adjustable jaw. The specifications differentiate this design from Loring Coes' April 16, 1841 patent 2,054 and Nathan Whipple's May 24, 1854 patent (patent application denied; the patent application including drawing appears in: COLLINS COMPANY vs. LORING COES, et al: Pleadings and Evidence. Boston, 1879).
Ken Cope's "American Wrench Makers 1830-1930" identifies the partnership of George C. Taft and John Gleason as producers of this patent, but it was not included in a list of patents Taft "licensed" to Daniel Hawkins, Jr. in 1859. |
