(under the class definition) Device including structure to
sustain a tool against gravity during the cutting operation, and mechanical means to displace the tool and hold the tool in position relative to the sustaining structure.
(1) Note. It is to be understood that the "means to move" of this subclass requires merely that the structure reasonably may be utilized to force a tool to move relative to a tool-support.
(2) Note. A simple spring or gravity-type tool-urging device is not considered to be "means to move" as required herein.
