Utica wrench disassembly

[netbrad]

I'm trying to clean up a Utica Tools 93-10 adjustable wrench but can't figure out how to get it disassembled. I don't see a way to access a set screw. I tried locking/turning the small knob but that only locks the jaws in place.

I'm sure I'm missing something obvious but I thought I would ask the experts.

Is there a tiny lock ring between the thumb wheel and the body of the wrench?

Not that I can see. The space is not big enough to be able to fit any sort of screwdriver or pliers in there anyway. Good thought though.

Darn.
Reason I thought that is because some Williams wrenches also had an adjustable pin through the thumb wheel and it was held in with a lock ring.
On Proto brand "Click Stop" model wrenches, one end of the spring that gives the thumb wheel tension sits in a pocket in the conventional manner but the other end spirals into a groove in the pin.
Yammering mode off.

Well, you might be right after all. I poked around Alloy Artifacts and found the patent which shows a lock ring but I still can't figure out how to get to it. I thought maybe I could unscrew the button head but it is apparently riveted in place.

I was working on disassembling a GearWrench over the weekend and a piece of spring steel can be beaten pretty thin to get into crevices and still be strong enough to pry. Might help ya.

Thanks. I think the ring is inside the thumb wheel which is adding an extra level of difficulty.
