✅ SOLVED Anyone recognize this early tool?

[Paleopilot]

It is some kind of clamp obviously, but for what? It is nickel plated steel, marked with either a "w" or "m" inside a diamond, logo. Pat date, 1915. I did an exhaustive search of old Williams tools and just about everything else I could think of. Still a mystery? Maybe a medical device? Any help would be great.

It almost looks like a nut splitter but it doesn't appear strong enough. The jaws don't look like clamping jaws but more like cutting or separating jaws. It might be an early version of a ball joint or tie rod end separator.

Maybe some kind of spring compressor?

Good work daroofa! Often called leaf spring spreaders (done by compressing). Note the patent date match from the ad shown in the link:
