Description: |
This type of jack was used for installing fences and for other purposes around the farm. An example closely matches the patent drawing and is marked with the patent date but no maker's name. The Bloomfield Mfg. Co. made very similar jacks but we are not completely certain that they were the manufacturer of this particular design. |
