Description: |
| Thomas P. How - patent attorney
In the previous construction adopted in the manufacture of chucks, the resolution of the force between the power applied and the resistance encountered as the chuck was drawn up, has had a tendency to throw the article chucked away from the face-plate of the lathe, or the bed, of the planer or shaping-machine, which tendency has rendered it very difficult to keep articles being chucked snugly to the face-plate or bed, and consequently difficult to secure them truly in position. My invention consists in the construction of the jaws of the chuck, and the nuts or their equivalent by which said jaws are connected to the screws or other device by which these jaws are operated, in two parts, so connected to each other that the action of the nut or its equivalent upon the jaw of the chuck shall have a tendency to keep the work snugly to the face-plate or bed, instead of crowding, it therefrom, substantially as herein more fully set forth.
