.~ Reciprocatory drive and advance originate from same mechanical element
DEFINITION
Classification: 173/144
(under subclass 141) Apparatus in which one mechanical motion converting element transmits motion from a source of power to cause cyclic to and fro rectilinear motion of a tool and to simultaneously cause or control forward movement of the tool.
