Normally I know the purpose of woodworking tools, but not of this odd clamp that I found in an old garage. I have not seen one before and wonder if anyone knows its purpose. I suspect it is for carpentry rather than fine woodworking.

At first I thought it might be one of the old attachments that was used to turn a 2×4 into a long panel clamp, but I have a few of those and they are different. This seems designed to clamp onto a board 1-1/2” wide with great force and then do something else, also with great force and with no concern about marring the wood. The “X” that is cast into each of the two clamp pads seems designed to dig into rather than protect the wood.

There are no markings except the “No. 1” and “1 1/2” shown in the photos.

Seems like the intent is to grab this and push on that. I bet it could come in handy sooner or later if you can find it when you need it ( or even remember that you have it). <grin>

Slide it along a workbench and clamp it where you you need it.

Could it possibly be a “wood stretcher”??? Lol.

It looks like something that might be used to pull a tenon out of a mortise.

If you clamp this fixture onto the end of a 2×4 and nail a block onto the the opposite end of the 2×4 (at just a bit more than the width of the boards you wish to clamp) you have a wooden “bar clamp” of sorts.

Least ways, that’s my guess.

There’s always a chance that the famous carpenter Xavier used it to sign his work.

I’ve never seen one but it would work very well in carvel boat building to clamp on to a rib and force a piece of planking down tight. We used another method involving wedges but this or something similar may have been it’s purpose.

The crank handle looks exactly like the ones on my E.C. Sterns clamps from the 1800s. They also made a lot of other styles and after long searching I did one time find one of their clamp catalogs online. They were from Syracuse, NY to help with the search process.

It looks like it was made to clamp onto a joist and push a warped floor board into line for nailing or screwing
down. I could have used it when I was putting the deck boards down last week. Anyone working alone
would really appreciate it. The mark in the joist would not matter or show, and the mark on the side of the
board would be covered by the next board.
