Description: |
| Examples of this auger bit have been reported—see photo. The smallest example is marked "Star Bit & Tool Co. / Rockford, Illinois" and the other two are marked "Greenlee / Rockford, Illinois". None is marked with a patent date which suggest that they were manufactured after the expiry of the patent. In fact, Star Bit & Tool Co. was established in 1911, decades after patent expiry. We cannot find any mentions of Greenlee auger bits before 1884, i.e., before patent expiry, but Greenlee Brothers & Co. of Rockford was a large business with a broad product line, and "auger" is a common enough word that it is difficult to be certain.Co-assignee H. H. Coe was a partner in machinery manufacturer Coe & Wilkes; we have found no evidence that that firm ever manufactured augers. As for inventor Calvin Wardwell, we can find nothing beyond this patent to tell us what he did for a living around this time. |
