Correct. The name is stamped on the handle, "Stillson Wrench."

Note that the Stillson Wrench in question was not made by Walworth but by The Erie Tool Works.

You can still buy Stillson Wrenches.


All of mine are of this design:


The pivot point on mine is at the knurled adjustment nut.
The Stillson pivot point is about an axle very close to the jaw.
Which one do you think grips a pipe tighter?

The wrench with the longest handle.
-----
(Toy train} wheels rotate upon an axle, fixed or rotating.
In the words of a search engine, " Did you mean 'axis' ?"

Pivot point(s) changes when the wrench grabs/locks on to the pipe/or fastener,
and changes again when the wrench is moved in the opposite direction.

But, you probably already knew that...

Just for conversation, and because I am curious, what sort of situations or tasks do you find yourself facing that require such a tool?

I had a couplie of those, decades ago, from my father's cache of tools in his workshop (as we called it,) in the basement of my childhood home, and never could figure out what to do with them. So, I gave them to a maternal uncle, who was thrilled. I never checked back to learn what he used them to effect, as I was on my way to college and never looked-back, in the direction of his workshop.

You can use them for dental work. Especially someone in need of an addytude adjustment. That's why they are called adjustable wrenches.
Those red wrenches are used on black iron pipe. They are able to bite into the pipe. Once it grabs hold. You can unscrew a length of pipe. Remember that iron pipe in your parents basement? It ran into the boiler for hot water heat. If that pipe broke it needed to be replaced. With a few pipe wrenches you could do the job.

Myron, let me rephrase the question...
The pivot point on mine is at the knurled adjustment nut.
The Stillson pivot point is about a pin close to the jaw.
These pivot points do not change as the wrench grabs/locks on to the pipe or fastener.
Don't be concerned with the wrench/pipe or wrench/ fastener system pivoting about the pipe after the jaws lock onto the pipe. Only consider the action of gripping the pipe before the pipe or fastener begins to turn.
For a same length handle, which design would have a greater grip on the pipe?

They are used to turn threaded steel gas or water pipe and the fittings for such pipes.

Task 1: Gas pipe to house rusted and leaked where it entered the house. I turned off the gas at the gas meter, dug up the old pipe between house and gas meter and used a pipe wrench to remove the pipe from the meter. From there I used two pipe wrenches to unscrew the rusty pipes all the way back to the house. At that point, I screwed and taped new pipe and couplings all the way back to the meter, connected the meter, turned the gas on, checked to leaks, buried the new pipe and relit the piolet lights.

Task 2: Water pipe leaked near the water meter. Did the same as above except water pipe does not get taped.

Task 3: Water valves (hose bibs) burst their tops the year it was 15 °F two days in a row here in Tucson. Used two pipe wrenches to replace the valves.

Task 4: Water heater got full of calcium rocks. Used two wrenches to remove the water heater, shake rocks out, and replace the water heater.

Task 5;' Water heater tank sprung a leak. Used two pipe wrenches to remove and replace old water heater with a new water heater.

Wow. You certainly are handy and adept at a whole lot of things. Your neighbors must love you because I would imagine you are quite helpful to them when needed, judging from your helpfulness and outreaches here on this forum on a wide variety of topics .
