DEFINITION

Classification: 72/112

Tool orbiting or rotating about an axis:

(under subclass 67) Subject matter including (a) a tool* that turns about an axis internal to both itself and the work, or (b) a tool that turns about a first axis internal to itself, and is mounted on a tool-carrier*, which tool-carrier turns about a second axis extending through the work.

(1) Note. The notes to subclass 67 define various movements disclosed in the patents of these subclasses (67+). Disclosure of a rotating tool (defined in (a) above) or an orbiting tool (defined in (b) above) will be placed in subclasses 112+. Disclosure of a gyrating tool (defined in subclass 67, (1) Note) will be placed in subclass 67.
