Abstract
Abstract A control device for a loading arm of a machine tool includes a cam coupled to the loading arm for moving the arm into two positions. A piston is also provided which is in communication with the loading arm and the cam. The piston maintains the arm in communication with the cam in the two noted positions and moves the arm out of communication with the cam and into a third position.
