Description: |
| The patent is for a quick-adjust wrench with spring-loaded catches between the two jaw segments.
Two wrench forms based on this patent are known. In one form, the "lower jaw" and handle are combined as indicated in the patent drawing, and the overall length of the wrench increases as the jaw opening enlarges. In a second form, the "movable jaw" slides on a toothed shank that has the fixed jaw on one end and a wooden handle on the other. |
