DEFINITION

Classification: 192/213.2

Plural radially spaced springs in a common radial plane:

(under subclass 213) Subject matter wherein a first helical resilient member has a centerline disposed a predetermined distance from a centerline of a second helical resilient member in a common plane perpendicular to the axis of rotation.

(1) Note. If the centerline of the first and second resilient members are also spaced from one another in a direction parallel to the axis of rotation, classification in subclasses 213.1+ is proper.
