Title: Well done? Medium Rare? Rare?
Post by: lptools on August 08, 2022, 05:55:28 PM: I had help finding the Patent Number on this one, but I can't seem to find anything else!! Not a sold listing anywhere, not even a photo!! 1,026,040 William A Hyle

Datamp has Barcalo -Buffalo as the manufacturer of this, but they only formed the business in 1914.
Speculation could imply that your"Find" could have been made by MacDonald and Sons, Ltd. - Toronto, ON Canada, the Assignee's listed on the Canadian patent prior to Barcalo manufacturing the unit after 1914.
Cheers

Post by: Danks on August 09, 2022, 10:28:40 PM: I doubt it, but it does have some similar Stillson attributes like Fixed Jaw on straight handle, hooked movable Jaw with adjustment thread along the shaft, adjustment done with a knurled cylindrical nut that is held captive in a cage. If you look up the patent for this wrench (USPN- 2,555,395) it cites the patent number for you wrench (along with approx 10 other patents) as relevant prior art. Cheers
