DEFINITION

Classification: 416/54

(under the class definition) Apparatus wherein an impeller* is mounted on or proximate an "art device" and is powered by the relative motion of the device or parts thereof, the device being of special construction or adaptation to perform a particular function other than that directly related to the support or operation of the class subject matter.

(1) Note. Patents in which more of the "art device" is claimed than is necessary to operate the impeller do not come within this definition, being properly classifiable with the art device, except in those cases in which there is no other suitable classification and the claim would be classifiable is subclass 146 as a "combined" apparatus in the absence of this or other pertinent superior subclass.

(2) Note. A particular object may or may not be an "art device" for this subclass dependent upon the impeller relationship therewith. For example, a vehicle may be an "art device" under the subclass definition when an attached impeller is arranged merely to cool the occupant but would not be so considered when arranged to propel the vehicle or to perform an essential function on some part thereof, as to cool the engine.

146+, for the combination of an impeller with an "art device" not involving operation of the impeller by the device and see (1) Note above for a general statement of the line with other classes.
