Trimont Monkey Wrench ???

[HeelSpur]

First one of these I have owned and the nut only turns about an 1/4 turn. It looks like the threads are flattened equally on both sides but others that I looked at have the same flattened looking threads. Is this normal???

And, there is a small screw or pin hole, is that a screw or pin???

I looked at it with a jewelers loupe but can't tell if its a screwdriver slot or just an indentation from a pin punch.

I'm thinking if I can take the spacer out I can get a closer look of the problem.

Neat wrench! I've not seen one quite like it before.

I think the threads are intended to be that way. That piece has a rectangular shape. Only the broadest areas reach deep enough into the threading die to be cut with threads. Most pipe wrenches are threaded that way, come to think of it.

I'll bet that pin you see holds in the spacer at the bottom of the threaded section.

Since the nut won't turn much, as you say, I'll bet the threaded section is gummed up/ rusted up in the housing of the wrench. It looks like the threaded jaw sandwiches around the frame of the wrench- a novel design that might be susceptible to jamming, depending on how tight of a fit it is.

I would turn the nut as far as it will go (in either direction) and tap with a mallet in the opposite direction to see if you can gently free the jaw.



Nice find, that's a keeper!

I got it moving and all it took was a tap on the back side of the jaw. The threads do look like they were milled even with the body. That spacer is what holds the jaw on.

Nice find, that's a keeper!

Those jaws are really parallel for a wrench from the teens, which I'm pretty sure that is(or earlier) judging by lack of a nut guard.

Ooooh nice!
That was their automobile wrench.
