Look familiar?

I was looking through a very old Model Engineer volume when I came across this. From April 23, 1903 M.E.:

Very little in the mechanical world is truly new. I suppose that there are just so many ways to do something and usually someone has done it before.

Wasn't the diamond tangential toolholder patented recently?.
This holder is 111 years old, and has an angle adjustment capability as well.

A similar one was featured in Edgar Westbury's book "Lathe Accessories" first published in 1943

I had a quick Google for both "Diamond tool holder patent" and "Tangential tool holder patent" and came up with nothing. I suspect that it was Patented before it's "re-issue" and the Patent is now lapsed. The "Eccentric Engineering" web site makes no mention of a Patent and there are so many instances of this showing up since the second world war that I doubt that there is a patent covering this particular "invention"!

shows an 1879 patent which looks like the one Steve found!
I've often thought about making one, maybe I'll get a roundtoit one day!

Hi Steve
What I like about this version, is its ability to be rotated, a nice feature.
Cheers David

I have old machining books and they depict bewildering different types of tool holders.
Ifanger has produced ages very nifty HSS "tangential" tools. They use special holder and HSS. But they look very well designed.
