Description: |
| Claim:
It is the object of my invention to improve upon jaws of the above class in several important particulars, the first of which is to provide a jaw which will grip and hold an a5 article firmer than those now in use; second, to construct said jaw in a way that the entire load will not come entirely against the clamp- ing-screw, but may be deflected against the ways in which the jaw is mounted; third, to so arrange the device that the adjusting- screw will not set up against the jaw and project therefrom, but will be arranged to one side below the plane of the jaw and at an angle thereto other than a right angle to the line of movement of the jaw, thus making the article more compact and requiring less space upon the table, all of which are very important features. |
