to a light vehicle, it is attached in front, thus transforming the same into a tricycle. In the case of hansom cabs it is attached at the rear. When it is applied to the heavier vehicles, such as express wagons, coal carts. etc., two idle wheels are attached to the motor wheel and work in unison with it.     One material advantage claimed for this system is that no reversing mechanism is necessary, the motor always running in the forward direction. If it is desired to back the car, the motor wheel is turned completely around in the steering socket and the motor started. It will be noticed that as the motor wheel is entirely self contained and has a single point of attachment to the car none of the twisting strains due to the irregularity of the road are thrown upon the motor. Moreover, in case of disablement of car or motor, the ease with which a change of motor wheels from one car to another can be made conduces to facility and rapidity of repairs.
