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 connect- 

 ing 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
