In many cases of electrical opera- one of great advantage for economical operation, particularlyas the improved Pond steel-tired car-wheel lathe, illustratedherewith, is capable of truing 42-in. wheels, with the hardestKrupp tires, at an average rate of six pairs per day of ten hours. The general view below shows only a portion of the en-tire equipment in this shop plant, there being installed herethree of the large 42-in. lathes, one of which appears at the the right of this is a smaller car-wheel lathe which differsfrom the 42-in. center-driven lathe, in that it is arranged for. A TYPICAL WHEEL SHOP FOR MACHINING STEEL-TIRED CAR WHEELS, SHOWING ARRANGEMENT OF AIR LIFT OPERATEDBY FOOT VALVES IN FLOOR FOR QUICKLY HANDLING WHEELS TO THE RIGHT-ANGLE TRACK don that might be cited, wheel problems of the magnitude ofthose met in steam railroad practice are incurred, which havecome to demand careful study. For the best results it hasbeen very generally found that this problem must be given very1 borough treatment, including frequent inspections of wheelsand truings in the lathe when worn badly in the face or flange;many economies may be ef- face-plate driving; this allows of truing sets of wheels withmotor gears in place upon the axles. Still, to the right of thelatter tool, may be seen an axle lathe, a wheel press and, lastly,a car-wheel borer. A noticeable feature of the arrangement ofthis shop is the absence of overhead crane or hoisting facilities;the scheme of handling: the wheel, as here arranged, entirely ob- fected in the handli
