Description: |
| The patent is for a wrench-head clevis pin with a swing-out lug instead of threads, and the corresponding toothed tapered surface on the clevis.
An example in a March 2012 mjdtools.com auction shows the tapered surface on the clevis body and wrench head of the pin, but does not have the swing-out latch on the end of the pin. That clevis is marked with the patent date. |
