. Machinery and processes of the industrial arts, and apparatus of the exact sciences. Chollet-Champions Mechanical Press. the crank on the axis of the vertical wheel E, which, by the Fig. Chollet-Champions Mechanical Press—enlarged view of upper portion. conical gearing and the gearing of the internal pinion and the wheel D,gives one turn of the nut of the press for twenty-seven turns of the 216 PARIS UNIVERSAL EXPOSITION. crank. When the resistance becomes too great to continue with fifteen-toothed pinion is brought into gear with the wheel E, andthe crank transferred to its axis. This combination gives one turn ofthe nut to eighty-one turns of the crank. Afterwards the fifteenTtoothedpinion is thrown out of gear and the nine-toothed pinion thrown gives a turn of the nut to one hundred and thirty-six and a halfof the crank, and is the largest multiplication of force of which themachine admits. With this combination a man, by applying to thecrank a force of fifteen kilograms, or about thirty-two pounds, can exerta pressure of nearly fifty tons on the entire surface of the body com-pressed. This press, for its neatness, compactness, and strength, iswo
