DEFINITION

Classification: 180/9.26

(under subclass 9.1) Motor vehicles wherein (1) a flexible track is always carried by a vehicle provided with ground wheels but by an adjustment of parts the vehicle is either a flexible track vehicle (i.e., a vehicle in which a flexible track engages the ground) or a wheeled vehicle (i.e., a vehicle in which all of the supporting means are wheels) or (2) a frame carrying a flexible track apparatus is mounted on a wheeled vehicle without removing any of the wheels from the vehicle.

(1) Note. Devices in which the drive wheel of a vehicle is removed and a flexible track apparatus substituted therefor, and devices in which a flexible track is applied to the drive

wheel of a motor vehicle to extend between such drive wheel and an idler wheel to convert the wheel vehicle into an endless track vehicle are not included in this subclass. Such devices are classified on other features in other subclasses under subclass 9.1.
