. American engineer and railroad journal . ery of alarge number of steel rails which were sunk in the Ohio Electrical World states that a crane boat will be equip-ped with waterproof magnets capable of lifting 4,000 poundseach. The work will be done by the Langton Electric Com-pany, Pittsburg, Pa. The illustration of side rods herewith, represents the prac-tice of the Philadelphia & Reading, as applied to consolida-tion engines, and Is printed by courtesy of Mr. E. E. Davis,Assistant Superintendent of Motive Power and Rolling Equip-ment. Evidence of careful thought Is seen in this design, par-ticularly in the ribbing over the ends, a place where a com-bination of strength and lightness is required as much as inany part of the rod, for the reason that a very light sectionmay be made here, and one that will successfully resist allpiston stresses, but at the same time the bushing may getloose. The rib should prevent this action while still preserv-ing a proper degree of lightness at the end. There are now ■fi-tti-. Cast Steel Side & Reading By. 50 sets of these rods in service, and they are so satisfactorythat all consolidation locomotives on the road are to be fittedwith them. A comparison of the cost of these with wrought iron rodsfor the same class of engine shows the steel rods to be some-wuat higher than wrought iron by the figures furnished byMr. Davis. Cast set of cast steel rods, finished, weight, 820 pounds. Cost of labor, finishing rods $ Total cost of rods without brasses Wrought set of wrought iron rods, finished, 810 pounds. Cost of labor, finishing rods | Total cost of rods without brasses The cost of labor for the steel is less, and the difference inthe total cost is therefore to be ascribed to the present highprice of the steel, which was due in part to rigid specifications for this material called for tensile strengtobetween 60,000 and 75,000 lbs. per square inc
