        Description: |  
| The inventor was a prolific designer of sawmill machinery. This jack was designed to lift low loads but keep the operator a safe distance from the load, e.g., when positioning the jack. The jack also lifts across a width so that one jack can safely lift a load prone to tipping, such as a lumber stack. |
