Mechanism of clutch of the movement of a milling machine carriage that includes an inverter clutch with central neutral position, driven by a fork applied elastically to the neutral position, characterized in that said fork is driven by a rod dragged by a first arm that rotates around a shaft, said first arm being in turn driven by a second arm that rotates about the same axis, and actuated by the control lever subjected to the action of the operator, the two arms being dragged to each other with a predetermined angular clearance, the first arm cooperates with a bolt held taut by a spring and tends to lock the rod in the clutch position, said bolt being able to back off, on the one hand by means of a pressure rod that can be operated by a stop supported by the carriage and, on the other hand, by a cam mounted on the second arm and functioning at the beginning of the angular stroke of this arm, at a torque pull from the clutch positions and within the angular clearance between both arms.
