: A steelworker plugs the cinder notch in the cast house at the Youngstown Sheet and Tube Company's Campbell Works, East Youngstown (Campbell), Ohio, ca. 1930-1939. Workers first flushed the slag out of the blast furnace at the cinder notch. Then they used a long steel bar called a bott to plug the cinder notch. At the end of the bar was the cinder notch plug, or the monkey bott. Later, at the end of the monkey bott was an oxygen lance. The worker operating the monkey bott was called a keeper.
