Description: |
| The 1864-12-03 Scientific American contains an illustrated article on this invention: "This ratchet drill is the most novel one we have ever seen. It is self feeding, and has the details of the ratchet portion arranged in a very ingenious and durable manner..." The article concludes by mentioning that is was being manufactured by Davenport & Betts of Stamford, Conn., which is a bit surprising since the inventor was manufacturing oil cans and other products. |
