Description: |
| The inner movable jaw of the wrench is positioned by the cam action of the end of the handle. A hook in the movable jaw rides in a groove in the cam, and studs on the movable jaw ride in slots on the bar(s) connecting the outer jaw to the handle. The specifications note the similarity of the mechanical action to Martin Payne's May 12, 1863 railroad rail punch (patent no. 38509). |
