DEFINITION

Classification: 416/83

(under subclass 79) Apparatus wherein the oscillatory working member concurrently undergoes some other diverse motion during the member operation.

(1) Note. The additional motion may be somewhat distinct from the oscillatory motion such as cyclic feathering, or may be integral therewith such as continuous rotation concurrently with oscillation to produce a resultant wave-like motion.
