DEFINITION

Classification: 72/403

With means to actuate tools in sequence:

(under subclass 394) Device, not provided for in preceding subclasses, comprising force-transmitting drive trains for

the two or more movable tools, said drive trains being so interrelated that one tool after another is forcibly driven into engagement with work and caused or permitted to remain in such engagement during an operation of the class type.

(1) Note. A device in which tools are to be successively applied to work by an operative following a manipulative routine may be found in subclass 394. For subclass 403, interrelated tool drive means is required. An interlock device for releasing tools only in a predetermined sequence would be regarded as constituting such interrelationship.
