Basically it's a goniometric collet holder, intended for electrolytic grinding. The text on sheet 5 of the patent sort of explains it.

tks, I read thru that, but its above me. Does it have any use today, besides a museum?

Like any specialized tooling, people who happen to need it, need it really bad. ... but people who don't happen to need it right now would have no interest.

Take some photos and put it on eBay.

I showed the item in question to a retired toolroom machinist and his immediate response was it was a device to facilitate the sharpening of tool bits. His opinion was that it was made for sharpening milling cutters.

tks, think it still has a use? I might try to sell it, maybe 100$?
