DEFINITION

Classification: 601/67

Unbalanced weight:

(under subclass 46) Subject matter in which the vibration is caused by a weight which is placed eccentrically on a rotating shaft.

(1) Note. These subclasses are for vibrators having unbalanced weights which do not answer to the other structural limitations of this class. Search subclasses which have specifics of the device before searching here for the motor structure.
