(under subclass 9) Subject matter in which the power transmitting mechanism is a mechanical gearing or gear.
(1) Note. For purposes of this class, "Mechanical Gearing" is described as a device comprising two or more relatively rotatable solid bodies each provided with interengaging
elements or frictional contact surfaces whereby one or more of the relatively rotating bodies, operating in rolling contact with another of said bodies, will transmit to or receive force or motion from said other body by virtue of such rolling contact. This includes belt gearing. Also a "gear" is described as one of the relatively rotating bodies in the preceding paragraph.
(2) Note. See the combination of an electric motor system of the type classifiable, for a reference to the electric motor driven gearing in this class.
