The maximum use of the high speedis made possible, resulting in a larger production; the cost ofmaintenance and repairs is reduced; operation is simplified andmade more convenient. An individual motor drive may be applied by the substitutionof a driving gear in place of the driving pulley and the additionof a motor platform and support, with the motor and the con-troller. Either direct or alternating current motors may be usedNo additional floor space is required and the motor driven ma-chines are symmetrical and compact in appearance. These ma-chines are manufactured by The National-Acme ManufacturingCompany, Cleveland, Ohio. Dinner to Hugh A!.
