DEFINITION

Classification: 416/98

(under the class definition) Apparatus comprising a working member* which rotates about a "fixed" axis and undergoes at least one different and distinct movement concurrently with the rotary motion.

(1) Note. The different movements for purposes of this subclass may be any combination of differing types, as rotary and oscillating, the same type movement about different axes, as plural rotary.

(2) Note. One of the movements may be of the unitary device such as a rotary fan supported* for oscillation, however, movement of an art device with which an impeller* may be combined does not comprise one of the motions for this subclass where such motion is incidental to, or the resultant of, impeller operation such as the motion of an impeller powered vehicle.

(3) Note. An axis is considered "fixed" even though it may be movable for purpose of adjustment or support on a movable art device such as a vehicle.
