DEFINITION

Classification: 72/462

TOOL AND/OR TOOL HOLDER:

(under the class definition) Apparatus comprising a tool*; or comprising a device connected to a tool* for mounting or supporting the tool against gravity, which device partakes of all the motion of the tool during deformation.

(1) Note. With respect to the definition of tool-holder (i.e., the supporting device) an original patent claiming relative movement of a tool and it tool-holder for purposes of adjustment of one relative to the other may be placed in this or an indented subclass.

(2) Note. This and indented subclasses are the residual loci of patents disclosing metal-deforming tools of general or unspecified use. Patents disclosing a specific tool, (e.g., fluent tool, roller-couple, closed-die) will be found in corresponding subclasses higher in the schedule than this one. Those patents claiming a tool particularly identified by disclosure as usable in a specific environment have been cross-referenced into the subclass pertaining to that environment.

(3) Note. During the analysis of patents to be placed in this and indented subclasses, the names applied to tools, (e.g., "anvil", "die", "mandrel", etc.) and the functions attributed to such tools, (e.g., "threading-die", "wedging block", etc.) were found to be arbitrary or not pertinent. Art terminology was found to refer to essentially similar structures by different names or functions, or to apply the same names or functions to widely divergent structures. For these reasons, the traditional names for the tools placed herein have been disregarded, and classification thereof has been based on structure without regard to function.
