Still used as a murder weapon in Clue, too. 

It isn’t a Stillson (pipe) wrench.

There is a fundamental difference between a pipe wrench and an adjustable wrench. The monkey wrench, the predecessor of the Crescent wrench has straight smooth jaws with a fixed top jaw and an adjustable bottom jaw.

The pipe wrench has a fixed lower jaw and an adjustable upper jaw. Both jaws have angled serrations to dig into the pipe. The upper jaw of a pipe wrench requires a certain amount of slop or pivot so the serrations can dig into the pipe.

I believe the monkey wrench is also often referred to as a Ford wrench because they were supplied with model Ts and perhaps others back when drivers were expected to know how to maintain their vehicles. 

I have one that belonged to my grandfather. It’s the best wrench for wheel nuts.

The wags I grew up with referred to adjustable wrenches, essentially Crescent wrenches, as "Mexican metric wrenches".    When I was learning Spanish names for tools I discovered that a Crescent wrench is a "llave Inglesa", or "English wrench".    I still find that amusing.

A pipe wrench is designed to that the upper jaw arm pivots, so that as you apply force to the handle, the jaws grip tighter.
