DEFINITION

Classification: 72/324

WITH CUTTING:

(under the class definition) Subject matter comprising method of or means for systematic cutting* of the material which is the subject of metal deformation.

(1) Note. See section VI, paragraph B, of this class for the relation of this class to other classes involving cutting, for a statement of the subject matter included in this class, and for examples of included and excluded combinations.

(2) Note. This subclass and the subclasses indented hereunder are the locus for (a) combinations of metal-deforming machines (or subcombinations thereof), or metal-deforming implements or tools; with actuatable cutters or organized cutting devices; and for (b) methods involving metal deformation and cutting, if not excluded by the class definition or provided for in preceding subclasses relating to specialized methods or apparatus (e.g., rolling, extrusion, etc.).

(3) Note. The presence of sharp points or edges on tools is not sufficient to identify the tools as "cutters" for any cutting subclass in Class 72, unless as disclosed (a) they

effect complete penetration of the work (with or without severance or removal of material), or (b) they effect a claimed cutting, incising, piercing, splitting, breaking, etc., as distinguished from mere deformation of material.

(4) Note. A claimed tool for cutting and deforming metal, but constituting less than an organized apparatus (e.g., lacking actuating means or coacting tool, etc., is subject matter for subclass 464.

SEE OR SEARCH THIS CLASS, SUBCLASS:

40, for cutting (e.g., grinding or turning), in mechanical cleaning combined with metal deformation. 55, for cutting combined with metal deformation by pressurized fluent material.

70+, for cutting combined with metal deformation by a tool rotating relatively to work about a motion center within work.

129+, for cutting combined with metal deformation by deflecting bodily moving work.

185+, for cutting with metal deformation by a "flying" tool.

203+, for cutting with roller or similar operation.

254+, for cutting with extrusion.

275, for cutting with rod, wire, or tube drawing.

294, for cutting with metal deformation by use of work-gripping clamp and relatively movable clamp or tool.

464, for a combined or composite metal-deforming and cutting tool; and see (4) Note to this subclass above.

29, Metal Working,

33+, for a "combined machine" excluded from this class (72) for reasons outlined in Lines With Other Classes, Relationship to Combination Classes, With Cutting of this class. 30, Cutlery, for a cutting implement or a work-supported cutter.

82, Turning, for cutting rotating work.

83, Cutting, for method or apparatus for cutting in general; see the class definition and notes for the locations of disclosures of various kinds of cutting and combinations with other operations.

225, Severing by Tearing or Breaking, for breaking or tearing apparatus.

227, Elongated-Member-Driving Apparatus, appropriate subclasses for a disclosure of cutting and deforming apparatus associated with a nail-driving device.

408, Cutting by Use of Rotating Axially Moving Tool, appropriate subclasses for cutting of that class type. The combination of cutting in a Class 408 manner with metal deforming of this class (72) will be found in this class.

409, Gear Cutting, Milling, or Planing, for other machining process or apparatus.

425, Plastic Article or Earthenware Shaping or Treating: Apparatus,

289+, for apparatus for shaping or reshaping nonmetals not otherwise provided for combined with preform severing means.

451, Abrading,

38+, for a process of sandblasting and subclasses 75+ for a machine for sandblasting. 470, Threaded, Headed Fastener, or Washer Making: Process and Apparatus, appropriate subclasses for metal deformation associated with cutting in the art of fastener making, except as provided for in Class 408.
