|
Description: |
| An improvement over Henry Disston's patent, 70423, which was apparently put into use at the Disston works and this patent reflect the experience with the earlier patent in use.
The swage is hung loosely to the bar and its movement is independent but limited by a pin in the bar. Disston's patent had the swage secured to the bar when used. |
