axle is that the carriage can be turned round in a very small space, and on that account the construction is well adapted to cabs.
Several arrangements have been devised by means of which the power can be applied to the front wheels, while these may at the same time swing round independent centers. One of these constructions is illustrated in Fig. 13, the first drawing presenting the appearance when seen from above, the second being a view from the front. In the first diagram the motor is shown at A, and by means of pinion B and gear C, motion is transmitted to the axle, which is shown more clearly in the right-hand figure. On the ends of the axle are bevel gears FF,

and these mesh into other bevel gears which revolve round the vertical studs D. Through this train of gearing the bevel wheels E are driven, and these are attached to the hubs of the carriage wheels. From the first diagram of Fig. 13 it can be seen at once that the gears EE can swing round D in either direction without in any way interfering with the transmission of motion from gears FF. The levers HH are secured to the sleeves GG which swing round the studs DD, hence, by connecting these with the rod J and moving the latter to one side or the other by means of the steering handle, the wheels are turned in any direction desired.
While this construction renders the carriage as easy to steer as those in which the motors are connected with the rear axle, it sacrifices the
