(under subclass 2) Spring device including a discrete swingably mounted, force multiplying link through which stress is applied to a spring element to compress, expand or laterally deflect a portion of the spring element.
(1) Note. Devices in which the link forms an essential part of the spring element are excluded.

5.5+, for a general utility land vehicle including an active suspension responsive to a force encountered while the vehicle is in surface traversing motion which may or may not involve a lever acting upon a spring device or element; subclasses 6.15+ for a general utility land vehicle including means, interposed between a vehicle body, chassis, or frame and running gear thereof, for altering height or levelness of the vehicle body, chassis, or frame which may or may not involve a lever acting upon a spring device or element; subclass 79 for a general utility wheeled land vehicle provided with springs between the wheel or wheels and the load-support, noting the search notes provided therein; subclasses 124.1+ for a general utility wheeled land vehicle running gear suspension arrangement; 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 a spring device or element (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). Patents classified in this class (Class 267) as originals may include vehicle parts directly related to vehicle suspension (e.g., fluid damper, upper or lower control arm) and vehicle parts which are nominally recited as either a reference or mounting structure for the spring.
