WITH MEANS TO EFFECT COMPOUND MOTION OF TOOL (E.G.,ROCKING):
(under the class definition) Device comprising means to move or guide a tool* in a generally tortuous path (i.e., neither wholly rectilinear nor wholly rotary about a fixed point) during a deforming operation.
(1) Note. This subclass is the residual locus of any metal-deforming device or portion thereof, not provided for in preceding subclasses, which comprises a tool guided or driven toward its effective position in a nonsimple path; such path may be, for example, a succession of broken line segments or a smooth (but nonarcurate) curve such as a spiral or an ellipse.
(2) Note. For placement in this subclass, the device must comprise means to cause the tool to depart from simple rectilinear or circular motion; e.g., if the tool is merely deflected from an otherwise simple path by the resistance of work, whether this be an intended or unintended condition of
operation, the combination does not meet the terms of the subclass definition.
(3) Note. This subclass accommodates a "rolling form" which picks up and bends or curls work as it travels thereover; the motion of the effective tool-face* is cycloidal, and the operation does not constitute "rolling" for subclass 199, because the tool-face remains in contact with the deformed work (see ROLLER* in the Glossary of this class).
