An Interesting Polygraph (Dupicator)

[chris paulick]

Does anyone else find this interesting or is it just me? It's Thomas Jefferson's polygraph used to copy his letters.

It's not just you. I like this pre-Xerox copier! Certainly some of us would like to see a dremel attached to it...

Thanks for the link.

Thats a beauty Chris, do you know if he made it ? or did he get someone to build it ?

I've seen a musical instrument that I think had something to do with TJ, dont know if he made it ,but it was a set of crystal bowls that rotated and it had a key board

hang on , better google it

Just looked it up, a Glass Armonica ,no keys just fingers on rotating glass bowls,invented by Benjamin Franklin, Thomas Jefferson liked it but did not buy one.

here is a link to a picture
