DEFINITION

Classification: 72/116

Plural, selectively usable fixed tools:

(under subclass 115) Subject matter wherein the stationary

tool is one of a multiplicity of such tools alternately usable to cooperate with the tool that is in motion.

(1) Note. Included in this subclass are patents disclosing a plurality of stationary tools of various sizes or shapes to accommodate variously sized or shaped workpieces and/or to produce products of varied size or shape.

(2) Note. Usually the work is a tube which is to be flared or flanged at an end by diametrically outward pressure of an orbiting or rotating tool inserted into the tube end. The stationary tool coacts with the rotating or orbiting tool by clamping the tube around the exterior circumference, thereof, in generally opposed relation to the interiorly positioned orbiting or rotating tool, whereby at least a part of the shape of the stationary tool is imparted to the flared or flanged tube end.
