The Works Of Messrs. Schneider And Co.

338 MESSRS. SCHNEIDER AND CO.’S WORKS. platform which rests, with the interposition of springs, on four driving axles each worked by a 200 horse-power dynamo. It contains ail the apparatus necessary to the good working of the motors; and to insure the safety of the electrical devices, it is fitted with a Wenger brake and with a screw brake. The eight wheels of the locomotive are 1.60 metres (•5 ft. 3 in.) in diameter ; each axle is worked through toothed-wheel gearing, by a separate motor. The four motors are of the ironclad type, with 6 pôles, of 550 volts, All arrangements have been provided in Order to । obtain an easy and progressive starting, and to prevent sparking, or to cut the sparks should they be produced । at the breaking of the current. The apparatus for reversing the current and coupling the motors is fitted i with double couplers, to secure efficiency. 1500 HORSE-POWER ALTERNATOR, TYPE O, CLASS 23. This three-phase alternator produces part of the Fig. 1096. 1500 Horse-powei’ Alternator. 423 revolutions, They are so iitted that all shocks are completely deadened ; they are joined to their respective axles, around which they can turn. The starting mechanism placed in the eab is provided with double levers, so that. the driver can always place himselE in the direction in which the locomotive travels.

At 70 revolutions per minute it has a frequency of fifty periods, and a tension of 3000 volts per phase. It consista of a fixed, laminated armature, 6.400 m. I (21 ft.) bore, held in a cast-iron shell, in two halves, whicli rests on two frames. (Fig. 1096 shows one of these J halves.) The armature coils are in recesses, cut along i the inside circumference. The magnet acts as a flywheel ; it contains 84 poles of j solid wrought iron, recessed in a cast-iron ring, weighing j 50 tons, keyed on the engine shaft. The magnet coils take I up the exciting current at 140 volts through two rings driven by the shaft, and fitted with bruskes (rubbers).
