DEFINITION

Classification: 72/303

Along curved path (e.g., tire upsetting):

(under subclass 302) Subject matter wherein the restriction of the path of motion is to a nonlinear or slightly curved line.

(1) Note. A typical device of this subclass is a tire upsetter comprising clamps for gripping spaced portions of a metal tire and means for urging the clamps toward each other along a path corresponding generally to the curvature of an average tire.

(2) Note. For apparatus affording truly pivotal motion of a clamp in metal deforming, see preceding subclasses 298+; in such devices, there need be no translatory motion of the clamp; the deformation is usually of a bending or twisting nature.

SEE OR SEARCH THIS CLASS, SUBCLASS:

298+, for metal deformation by rotation of a work-gripping clamp about a fixed axis with respect to a fixed clamp, and see (2) Note above.
