According to the U.S. Patent, the machine was described as a Device For Obtaining Intimate Contact With Engaging, Or Clamping Bodies Of Any Shape, or DFOICWEOCBOAS for easy. It contained 30 nested rotating jaws.
Application filed March 21, 1912.
Serial No. 685,288.
The invention purposes to effect by means of rotatable and oscillatable cheeks, an intimate contact, engagement with or clamping of bodies of any shape, the contact being effected at as many points as possible, Whereby owing to the reactions or the automatic adjustment to the position of equilibrium of all the cheeks, if the latter are symmetrically arranged, the pressure is uniformly distributed over all points of contact, while if the arrangement is unsymmetrical there is a greater pressure to one side.
Inventor Paulin Karl Kunze was a “subject of the Emperor of Austria-Hungary, residing at Vienna.”
The term fractal was coined by French mathematician Benoit Mandelbrot in 1973 and is defined as “never-ending pattern.” Jump to 34:00 for a silly but cool demonstration of the completed restoration.

Tacky Raccoons 
Your Google-Fu is outstanding Bunk.
Well done sir!
Even when I was looking around for it I never found the Mantle Vise.

I’m a DuckDuckGofer with a healthy bit of OCD I guess; I blame the drugs.
I couldn’t find any biographical info on Kunze. There’s another Paulin Kunze from Munich who patented a wire cutter possibly P.K.’s son, died in 1980. Age difference is too great to be the same guy.

Kinda hard for me to read with the low contrast font, but otherwise very cool.
I’ll have a look around – I love this stuff, but don’t tell anybody.

Sorry about that. I really should make a light version but I’m very adverse to bright white backgrounds. As a workaround, your web browser should have a way to override a website’s colors and/or styling.
