Description: |
| A cam lever on the top of the pin, and notched and flattened tip of the pin, together with features on the body combine to form a latching clevis pin which would not work free or fall out.
Brought into production as the FERRIS SAFETY CLEVIS around 1901: the company formed to produce it appears to have failed within a short time. |
