(under subclass 400) Devices in which one or more of the vehicles has wheels movably mounted thereon for steering movements and such steering movements are controlled by a change in articulative relationship between the vehicles.
(1) Note. Merely a single swinging axle which is directly connected to the draft connection between the vehicles to be swung thereby is excluded from this and indented subclasses.
(2) Note. The turning of a single dirigible wheel or closely paired wheels of tricycle running gear is included here.
