Description: |
| Plane designed to use inexpensive razor type blades and specifically mentions Gillette safety razor blades. Nineteen claims compose the patent all prefaced with "In a plane,..." This appears to be more of a patent of a concept rather than a idea ready for production.
This patent along with three others: 1,553,642, 1,651,634, and 1,662,005 were the basis and improvement of Stanley's Ready Edge blades. |
