What's a self-adjusting double-driving centre chuck?

student123 · Sep 16, 2010

I've been reading about Joseph Clement , a machine tool pioneer who worked with/for Charles Babbage. In 1827 Clement won an award for his "self-adjusting double-driving centre chuck".

Can't find much on the web about it.

Any idea what one of those is /might be?

Just curious, thanks in advance.

Interesting reading, anyways. Sounds like 180 years ago Joseph Clement had a lot of influence on modern machine tools.
