A power tool is a tool that is actuated by an additional power source and mechanism other than the solely manual labor used with hand tools. The most common types of power tools use electric motors. Internal combustion engines and compressed air are also commonly used. Tools directly driven by animal power are not generally considered power tools.
Joseph Buford Cox, was an American inventor and businessman. He 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 timberman beetle. Cox watched the destructive larvae of the timber beetle for many hours. The beetle's cutting action was left and right, side to side, rather than scratching or burrowing straight ahead. Cox adapted this concept to a new chain saw of his own design put into production during the late 1940s.
