Description: |
| My invention ... consists in a monkey-wrench having pivoted thereto a jaw which is adapted to engage with pipes and round rods, and which jaw is a permanent attachment to the wrench, but which can be moved back out of the way when not needed.
It also consists in a monkey-wrench provided with a sliding jaw, and a screw for operating the jaw, both the jaw and the screw being detachable, combined with a movable and adjustable jaw which is pivoted upon the monkey-wrench, and a spring for holding the jaw normally in contact with the stationary jaw." -- from the specifications.
Ken Cope's "American Wrench Makers 1830-1930" reprints an 1895 ad indicating the manufacturing rights were for sale.
The drawing in the 2nd image appears in an April 15, 1896 HEATING and VENTILATION description of a new wrench produced by Edward Barnes of Dorchester, NE. |
