The remaining pngravings on this page illustrate the applica-tion of the motor drive to a 200-ton, 48-in. hydrostatic wheelpress, built by the Niles Tool Works. The motor, which is a10 multiple-voltage Crocker-Wheeler motor, is geareddirect through a single-reduction to the eccentric shaft fromwhich the pumps are actuated. This is an excellent exampleof the compactness and simplicity ottered by the motor drive. Mr. E. B. Thompson has been appointed master mechanicof the Iowa & Minnesota division of the Chicago & North-. 1^/^
