Description: |
| The clevis design includes a "wrench-head pin" and is clearly related to Darrow's Aug. 21, 1866 patent (no. 57,436), and June 18, 1867 plow clevis design patent (no. D2,674).
A known example is marked with the patent date.
According to Jack Devitt's "Ohio Toolmakers and Their Tools," James L. Haven & Co. and successor firms produced a variety of ironware from the late 1850s well into the 20th Century. |
