DEFINITION

Classification: 446/168

INCLUDING UNATTACHED GRAVITY-FED ROLLING, TUMBLING, OR ENERGY-IMPARTING FALLING ELEMENT, OR PATHWAY THEREFOR (E.G., MARBLE RUNWAY):

(under the class definition) Device including an unattached element which either (1) moves down an incline under the force of gravity by turning over and over along the surface of the incline, or (2) drops through the air or travels down an incline to supply energy to a movable portion of the device to cause movement thereof, or (3) a track or guide for such an element, in (1) or (2) above.

(1) Note. Devices having pivoted parts and adapted to move down an incline (e.g., "walking" dolls) are not considered to be elements as defined above, nor are wheeled devices adapted to move down an incline.

(2) Note. Devices having a supply (e.g., magazine) in which elements are successively presented, or incrementally roll down an incline toward a dispensing outlet are not classified in this subclass on that basis.
