To quickly assess the difficulty of the text, read a short excerpt:
All the gears, including the scrap gears, are quenched direct from the pot in this manner. The gears then go to the reheating furnaces, situated in front of a battery of Gleason quenching machines. These furnaces accommodate from 12 to 16 crown gears. The carbon-steel gears are heated in a reducing atmosphere to about 1,425°F. (depending on the carbon content) placed in the dies in the Gleason quench- ing machine, and quenched between dies in mineral oil at less than 100°F. The test gear receiv...es exactly the same treatment as the others and is then broken, giving a record of the condition of both case and core. Affinity of Nickel Steel for Carbon. — The carbon- and nickel- steel gears are carburized separately owing to the difference in time necessary for their carburization. Practically all printed information on the subject is to the effect that nickel steel takes longer to carburize than plain carbon steel. This is directly op- posed to the conditions found at this plant. For the same depth of case, other conditions being equal, a nickel-steel gear would require from 20 to 30 min.
