DEFINITION

Classification: 494/75

And each extending outwardly in curve of changing or constant radius:

(under subclass 74) Apparatus wherein that dimension (i.e., width) of each element which extends outwardly describes, in a horizontal section, a nonlinear path in the nature of either a spiral or an arc of a circle.

(1) Note. By virtue of their curvature, the elements of this subclass intersect radial lines of the member.

(2) Note. The elements may be resilient in nature, in which event their curvature may be the result of their being forced, distortably, into position within the member.
