DEFINITION

Classification: 267/259

Compound:

(under subclass 2) Spring device having individual diverse spring elements each of which serves to cushion relative movement between parts of the vehicle.

(1) Note. The original basis of classification in this and indented subclasses was by total disclosure rather than by claimed disclosure; i.e., if a claimed spring element was specifically intended to be used in combination with a leaf-spring, the leaf-spring is considered to be part of the device for classification purposes, even though not actually claimed.

(2) Note. An elastomeric or rubber bushing employed to mount a spring element in most cases is not considered to be an "individual" spring element itself, particularly where its cushioning effect is negligible when compared with the spring element itself. However, where the disclosure clearly indicates or implies a cushioning effect upon the vehicle parts, an elastomeric or rubber element has been considered to be a separate spring element proper for classification in these subclasses. Analogously, a torsion tube assembly comprising a steel torsion rod with a surrounding elastomeric or rubber sleeve to cushion the vehicle parts is not considered to be diverse spring elements for classification in these subclasses, but rather has been deemed an individual torsion spring proper for this class (267), subclasses 273+, provided later in the class schedule.

124.1+, for a general utility wheeled land vehicle running gear suspension arrangement which may or may not involve plural spring devices or elements, especially subclasses 124.162+ which are directed to a residual fluid suspension combined with a mechanical spring device or element or subclass 124.165 which is directed to a combination of plural, diverse mechanical spring devices or elements; or subclasses 275+ or 283+ for a general utility occupant propelled-type wheeled land vehicle including yielding framework or running gear which may or may not involve plural spring devices or elements (it is noted that in accordance with the (2) Note of Class 280, subclass 200, motorcycle frames and running gear, without features causing classification in Class 180, Motor Vehicles, are included in these subclasses).
