DEFINITION

Classification: 83/471

(under subclass 469) Device including means adjacent the defined cutter for sustaining the work against the force of gravity in the vicinity of the cutter or against a radial force exerted by the cutter action on the work.

(1) Note. For a patent to be placed herein, the work-supporting function of a table or other element must be recited in the claim or be clearly inferred from the context of the claim. For patents in which a table is claimed as supporting a guide for a tool carrier, see subclasses 485+.

(2) Note. For other devices including a cutter and a related work table or work-support, see the subclasses indented under subclass 425.

(3) Note. Included in the indented subclasses are patents in which the cutter comprises a radial face and a frusto-conical or cylindrical surface, in which the surface is claimed as a work-supporting surface. A disc-blade and cylindrical backup anvil, combination, wherein the cylindrical surface is, in effect, a cutting element as well as a work-supporting surface, is not proper for this subclass; see subclasses 505+.
