DEFINITION

Classification: 83/861

OTHER THAN COMPLETELY THROUGH WORK THICKNESS OR THROUGH WORK PRESENTED:

(under the class definition) Method or apparatus utilizing a tool which: (a) is disclosed as limited to engage operatively only one of the nonthickness work surfaces (and which may or may not engage operatively a thickness work surface), or (b) has operative (i.e., cutting) engagement with only a thickness face and which is constrained to an operative path lying between the nonthickness faces, or (c) has a tool stroke* in a single rectilinear path, which stroke fails to completely cut all the work lying before it in the direction of its cutting path (even though the resulting line of cut may extend entirely through the thickness of the work).

(1) Note. A thickness surface is one along which the "work thickness" may be measured. See the illustration below. [figure] [caption]"Nonthickness Surface"; "Thickness

Surface"; "Work Thickness Dimension"

(2) Note. For a patent to be placed originally in this or indented subclasses, it is not required that the contemplated type of cutting be distinctly claimed. It is sufficient that the claimed means be disclosed as functioning within the limitations above defined.

(3) Note. Where the tool operates to produce a mere indentation or distortion of surface material (i.e., without severing the work surface fibers), as for instance, by creasing, forging, or metal rolling, or combines cutting with a significant material flow, as for instance in sheet forming and in plastic working, then the patent for such defined subject matter is excluded from this class and will be classified in other classes according to material worked on, type of operation performed, or machine disclosed.

(4) Note. Where the disclosed apparatus is directed to subject matter as above defined but the claimed recitation is limited to a cutter, per se, then the patent for such is originally placed in a subclass of tools, per se (651+).

(5) Note. Where a tool element penetrates partially through the thickness of a workpiece and thereafter continues to coact with an opposed tool element, which opposed tool element completes the severance of the workpiece in the cutting plane extended of the first tool, then the combined cut through the work is considered the same as the product of a single coacting tool pair and the patent directed to such subject matter is excluded from this subclass and those indented thereunder and will be found elsewhere in the schedule. However, if the first said tool is withdrawn from the workpiece before the complete severance occurs (i.e., no coaction occurs between said elements) then the first tool element is considered to be a scorer means and the opposed tool element a through cutter, and a patent disclosing same is placed as an original copy in this or indented subclasses.

(6) Note. The main body of the class (subclasses 13+) always should be included in the search for a particular process, or apparatus, for cutting partially through the thickness of the work, which process or apparatus additionally may be applied to cutting entirely through the work thickness.

9+, and 21.5 the generic loci of patents directed to apparatus and process, respectively, for splitting or skiving of leather.

72, Metal Deforming, appropriate die-pressing subclasses; e.g.,

343+, for channeling, grooving, or partially penetrating with a punchlike tool

101, Printing,

3.1+, for related art in printing.

493, Manufacturing Container or Tube From Paper; or Other Manufacturing From a Sheet or Web, appropriate subclasses for combined operations in making a product from a sheet or web including cutting other than through the thickness of the material.
