Description: |
| The wrench has four jaw sections connected to a cap. Internal springs hold the jaws open. A screw collar adjusts the jaw size, and a side lever handle. The patent drawings show open end wrench openings on the end of the handle.
A known example is too rusted and pitted to see any markings. |
