Link driven by crank:

(under subclass 330) Apparatus wherein the second member causing the rigid connecting member to move is adapted to turn about an axis and is pivotally connected to the connecting member at a location offset from the axis so that rotation of the second member causes the end of the link connected thereto to orbitally swing and drive the cutting tool.
