Number: 83
Name: Cutting >
Description: Class 83 is the residual locus of patents directed to methods and machines for penetrating material, without substantial reshaping flow of such material, by means of (1) a solid tool, or fluid current, either of which applies mechanical deforming force to the material by direct physical contact therewith, the fluid current forcing the material against a solid tool whose edge defines the line of cut; (2) a heated solid tool which directly engages the material (to effect penetration thereof by melting, or by transmission of mechanical energy, or both); or (3) opposed, controlled fluid currents.
