Among the machines equipped may be mentioned cranes,power presses, lathes, planers, drills, milling machines, pro-filers, emery grinders, hydraulic presses, boring mills, etc. Themotors used for driving these various tools are designed andadapted for the tools mentioned, and are built into the head-stocks of lathes, while in other tools they take the place of thedriving pulley and require no additional room. The motorsare of the Bullock slow-speed type with the variable speed con-trol governed by the Bullock multiple voltage system. Thetools may be operated in six varying speeds in either direction,without the ttse of back gearing or any resistance in the elec-trical Machine Shop.
