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.
 US patent 510263.

    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!
