This tool is equipped with a type Aft. multiple-volt-age system controller and the type 3 F., M S., C. M. variablespeed motor, to develop 4 horsepower at 240 volts, built by theCrocker-Wheeler Company. The range of spindle speeds and the power provided through-out are the same as for the vertical drill presses described inthe fifth article of this series (see pages 441-2, December, 1903,issue), and the diagram shown on Fig. 25 of that issue showsthe variations of power at the various speeds. Because ofthe large number of speed steps provided and because of theease with which speed can be chan
