In referring to the large motor-driven Bement-Mlles wheellathe at the West Milwaukee shops of the Chicago, Milwaukee& St. Paul Railway on page 1S5 of our May, )&03, Issue, wewere inadvertently in error in stating that the motor usedfor the drive a General Electric motor; we take pleasurein stating that this motor was built by the Milwaukee Elec-tric Company, Milwaukee, Wis. We are informed that this driving-wheel lathe, the photo-graph of which is reproduced herewith for reference, has madea remarkable record in operation. This tool is one of theheaviest driving-wheel lathes ever built, having a capacityfor turning tires up to 100 ins. in diameter. The size of thelathe may best be judged from the fact that it weighs, exclu-sive of the motor, 112,000 lbs. The motor is one of the stand-ard direct-current machines built by the MilwaukeeElectric Company. It is equipped for a 30 per cent, speed. 100-IN. DRIVING-WHEEL , MILWAUKEE & ST.

The interesting test was made upon this lathe last pair of 84-in. tires were turned simultaneously with anaverage depth of cut at each tool of 5-16 in. and a feed of3-16 in. The cutting speed was 18i,i ft. per minute. The aver-age horse-power required at the motor was I6V2 , but whencutting through hard spots on the tires the power requiredjumped up as high as 22V2. Under this heavy duty the timerequired for the work was 63 minutes. It is to be noted that the power required during this per-formance was very high, as the majority of motor-drivenwheel lathes in use in this country are equipped with We are pleased to learn also that the method of driv-ing through cone pulleys, arranged with close centers and noadjustment for tightening the b
