I looked at that link and then went and looked in my book, chassis engineering by Herb Adams and found nothing. I read about the Watt's linkage and then looked at the pics again. I still don't get it.
Edit:
Dug out my book "competition car suspension" by Allan Stanforth and found only one reference to "Mumford" and I'm not even sure it's the same guy.

One other approach to roll, currently under serious development for the car industry, is invento Mike Mumford's answer to the question, "What does a car really need?" Given the answer, "Better ride, less roll", computer/hydraulic control of an otherwise orthodox tube or bar is a solution if it can be produced simply and cheaply enough.
I just read a review of this book on Amazon that ironically said:

For example, while this book had descriptions of solid rear axle suspension types (the same ones covered in his previous book,) it left out the "Mumford link" suspension. Surely the newer book should have described the most recent suspension, but it isn't to be found. I guess there's only so much to automotive suspension design, yet I assumed the new book would have "new" information, necessitating it's publication. I just don't see it
No answers there either. A Google search revealed that Michael A. mumford applied for a patent for a "anti-roll" suspension in 12/04, but that could be something different.
Well, after staring at it for a while (I made it smaller so I could see it better
) I think I at least have a vague understanding of how it works. It looks very enticing to me. If I go live axle I may have to try it. Nice find!
