DEFINITION

Classification: 83/298

(under subclass 284) Device in which both the work-feed means and the means to move the tool through a cutting action or cycle are provided with independent power trains, each of which trains has a speed changing means which is adjustable to vary the speed of its driven element (tool or work respectively), and a common mechanism is provided to interdependently regulate the several speed changers so that an adjustment of one will be accompanied by an adjustment of the other.

(1) Note. A mere common drive does not fall within the meaning of this subclass, and will be found below; e.g., in subclass 339.
