I used to work for The American Tool Works Company in Cincinnati, OH. This afternoon I was lookign for an ATW Logo for a web site I am setting up and found a reference to: BOURN &N KOCH Inc. Never heard of them before today, but they claim to have purchesed the Intellictual Properties to American Tool Works. Hmmmm. Don't know where that came from. ATW Was eventually purchaed by Bullard and the remains of anythign left was move to Rock Island.
Anyhow, you may look at:

In Hamilton, OH there was a company who claimed to be American Tool Works. Another compay out there living off an old name. The American Tool machines are very well made and will remain running for years as long as people can get parts for them.
