Description: |
| "My invention relates to automatic knife-grinders for planing-mills, box-factories, furniture-factories, &c.; and it has for its object to provide a grinding-machine which will automatically carry the knife back and forth in contact with the grinding-wheel, and which can be so adjusted that when the knife has been ground to the desired degree the knife will be automatically held from contact with the grinding-wheel." |
