Joseph Buford Cox (1905 - August 10, 2002), invented what is now known as the chipper type chain for chain saws. He based his design on the C-shaped jaws of the larva of the timber beetle.
Joseph and his wife, Alice, founded "The Oregon Saw Chain Co." in 1947. Cox later started a small casting company called OMARK, now known as "Omark Industries". In time, Oregon Saw Chain became a subsidiary of Omark Industries which was in turn acquired in 1985 by Blount, Inc., of Montgomery, Alabama. Blount merged in 1999 with Lehman Brothers Merchant Banking Partners. The company is known today as the Oregon Cutting Systems Division of Blount, Inc. Most chainsaws, with the exception of some Stihl saws, use an Oregon chain based on the invention of Joseph Buford Cox.
Joseph Buford Cox only reached the fifth grade in his formal education.
They had no children. The value of the estate was donated to a charity in central Minnesota.
