Electric Locomotines for ; Coal Mine.—The 50-ton electric locomotives for use by the Fushun col-lieries for freight handling are the first of the kind ever builtat the South ^Manchuria Railway workshops. They are forthe standard gage. Each locomotive is designed to haul 580-ton trains at the speed of miles per hour on the leveltangent track, exclusive of the weight of the locomotive, thetrolley voltage being 1,200 volts. They are of the two-bogietvpe, each bogie carrying 125-horsepower motors. The totalweight is 97,200 lb.; ballast weight, 15,200 lb.; weight ondrivers, 112,400 lb.; weight per driving axle, 28,100 lb.; andweight of a motor, 5,000 lb.—Commerce A NEW AXLE LATHE The Xo. 3 axle lathe illustrated in Fig. 1 is a high pro-duction machine recently placed on the market by the Niles-Bement-Pond Company, 111 Broadway, New York. Il isdesigned for machining forgings, as well as roughturned axles, and being center driven is adapted for turningwheel seats and journals at both ends of car axles simul-taneously. The bed is of rigid construction reinforced by cross-girtsof box section 8 in. wide. The tracks for the carriage con-sist of a wide flat way at the back of the bed and a track ofan improved compensating V shape at the front. ThisV track has an angle of 15 deg. at the Ijack and an angleof 70 deg. at the front. The 15 deg. angle on the back of herringbone gear provides a smooth, powerful drive, and allobjectionable noise is eliminated when running at high veloc-ity. The axle is driven by a steel equalizing driving plate,having lugs cast integral which engage both ends of thedouble driver dog. By m
