DEFINITION

Classification: 172/400

(under subclass 395) Apparatus in which a plurality of wheels are independently mounted on different axles and there are additional means interconnecting the wheels whereby they may be moved simultaneously vertically with respect to the frame or so that the movement of one vertically with respect to the frame influences movement of the other, and there is an actuator for moving a wheel.

(1) Note. Plural wheels mounted at different ends of a crank axle or other axle whereby the wheels move together without use of any connecting links or separate power units are considered not to be independently mounted on different axles. Wheels so mounted do not come under the definition even if they are adjustable with respect to each other.
