Jones's improved wrench, 1893
The common adjustable wrench with integral rack and worm had already been around for decades when Edward Jones proposed this idea which seems to require a second tool to adjust the jaw size. Not sure what the advantage is to this design.

Stranger still, the moveable jaw is at the "far end" from the handle, making a sloppy tool even worse.
I think maybe Mr. Goldberg was drinking one night and cursing Mr. Crescent! I wonder how long that tiny spring would last? And as for needing another tool for the tool I have several tools like that and I curse the day I bought them!
