ABSTRACT:
The controlling lever of the mechanism for use in civil work machines or cargo winches is supported by a spherical bearing so as to be tiltable in any direction by any inclination angle. Four horizontal shafts are provided to extend in the +X, -X, +Y and -Y directions of a rectangular coordinate about the center of rotation of the controlling lever. Four arms are rotatably mounted on respective shafts and are biased by torsion springs wound about respective shafts. Slidable contacts are mounted on respective arms to slide along rheostats, thus producing electric signals proportional to the direction and angle of inclination of the controlling lever.
