Modern mechanism, exhibiting the latest progress in machines, motors, and the transmission of power, being a supplementary volume to Appletons' cyclopaedia of applied mechanics . re equivalent in conductivity to No. 7wire, so that there is little danger of undueheating under the severest strain of service. The Lae electric railivay system presentssome radical differences from any of theothers heretofore mentioned. A single motoris used, rigidly attached to the truck, andthe armature spindle is parallel to the lengthof the car. The power is transmitted to bothaxles from the same motor through beveledgearing. Fig. 12 gives an idea of the princi-pal characteristicsof the system. The motor is placed cross-wise of the car midway betweenthe wheels, and fastened rigidly to the framework of the truck. The armature pinion drivesan intermediate gear that, through the bevel-wheels, turns the axles. The motor is ot dOhorse-power, with a Siemens armature ; it is thoroughly insulated at the sides by oak-bars saturated with asphalt, and the employment of raw-hide or fiber armature pinions stilfurther frees the machine from danger of a ground. The whole truck is _put togethei. 12.—liae motor.
