Description: |
A major feature of the patent is the adjustment lock slide on the back. Turning the handle moves the "outer" jaw. The drawing show options for nut or pipe jaws. Known examples do not include the adjustment lock, or pipe gripping jaws. They do include a spring / ball detent between the handle and lower jaw which provides a type of "adjustment stabilizer." Some have SUNAPEE, N.H. as the company location. |
