Description: |
| The patent claims the two set screws located in the sides of the stock near the mouth. The set screws bear on the cutter and provide a fulcrum for the lateral lever. Traut never explicitly states an advantage for this mechanism.
John Walter reports that this date is stamped on Stanley benchplanes, and the well known type study by Roger Smith shows it appearing at type 5 benchplanes, but according to the History of Stanley R&L Co. written by James Burdick c. 1930, this patent was never used. Lee Valley's Veritas Tools does currently produce bench planes with this feature.
This patent date is marked on the lateral lever along with the patent date for 173,177, and 386,509 on type 5 planes. |
