429  DF  WITH MEANS TO DRIVE TOOL {11}
430.~ Including magnet, solenoid or explosive


DEFINITION

Classification: 72/430

Including magnet, solenoid, or explosive:

(under subclass 429) Apparatus wherein the tool moving means includes (a) a body capable of attracting ferrous material, or (b) a charge of chemically reactive material that rapidly expands upon actuation.

(1) Note. This subclass is not the locus of patents disclosing an electric motor (i.e., a stationary part and a continuously rotating part, the rotation occurring as the result of passing a current of electricity through one or both of the parts), which motor is the drive means for the tool. This type of disclosure of a tool and an electric motor

to drive the tool is located in other subclasses on the basis of the tool and its movement.
