INCLUDING MEANS TO VIBRATIONALLY ISOLATE A DRIVE MEANS FROMITS HOLDER:
(under the class definition) Subject matter having structure which a) is positioned between an apparatus causing motion of a tool, i.e., tool drive means of the apparatus, and b) functions to attenuate oscillatory or shock motion originating in the tool drive means hindering its transfer to the manipulating or supporting means.
(1) Note. A means to dampen transmission of vibrations
within the tool drive means, i.e., between a power source and the tool, is not included under this definition.
