Definition

This class includes machines, tools, and processes not otherwise classified for operating upon stone or stone-like substance, which has previously been removed from its native position in the earth, and also some miners" hand-tools. This class does not include:

(1) Inventions classifiable in the class for Mining or In Situ Disintegration of Hard Material, for mining valuable material or disintegrating hard material in situ (See Search Notes below for specific class reference.);

(2) Inventions classifiable in the class for Abrading, for operating upon the surface of the material with an abradant; (See Search Notes below for specific class reference.);

(3) Processes and apparatus for comminuting stone and stone-like substance, classifiable in the class for Solid Material Comminution or Disintegration. (See Search Notes below for specific class reference.) Class 125 includes some patents for working stone or stone-like comminuting elements (e.g., millstones) to prepare them for use. See particularly subclasses 27+ and 42.

(4) Inventions which are equally useful for operation upon metal and are classifiable in classes for Metal Working; for Turning; for Cutting; for Cutting by Use of Rotating Axially Moving Tool; and for Gear Cutting, Milling, or Planing. (See Search Notes below for specific class references);

(5) Inventions which are equally useful for operation upon softer material, like wood and are classifiable in classes for Cutting; for Wood Turning; and for Woodworking (See Search Notes below for specific class references);

(6) A process or means for boring into the earth, concrete, stone or the like in situ is classified in the class for Boring or Penetrating the Earth, as is a hammer or impact device for impacting an earth penetrating means. (See Search Notes below for specific class reference.);

(6A) The class for Tool Driving or Impacting provides for subject matter directed to driving or impacting a tool, when such subject matter includes combined features peculiar to tool driving, but which does not include features limiting the subject matter to a specific tool art, such as specific shape of the work contacting portion of a tool, related tools, or an opposed work support. Class 125 has not been cleared as to subject matter in conflict with this line. (See Search Notes below for specific class reference.)

(7) Tools in which the invention resides merely in the means for securing the operating portion of the tool to the handle or holder. These are classified in the class for Chucks or Sockets. (See Search Notes below for specific class reference.)

(8) The subcombination of cleaning stone or brick by detergent, for which see the class for Cleaning and Liquid Contact With Solids. (See Search Notes below for specific class reference.)

(9) Ice picks and chippers, for which see the class for Cutlery Cutlery. (See Search Notes below for specific class reference.)
