ABSTRACT:
A directional starting spring which ensures that an AC synchronous motor is rotating in the proper direction is disclosed. The AC synchronous motor includes a circular magnet rotating in "synch" with the frequency of the alternating current. The magnet rotates a worm gear attached to the center on its axial face. This worm gear drives a second worm gear positioned perpendicular to the first worm gear. The second worm gear drives a series of gears which display the elapsed time. Attached to this second worm gear is the directional starting spring. If the motor is rotating in the proper direction the spring contacts the housing of the meter and slides on the second worm gear. If the motor is rotating in the wrong direction the spring contacts the axial face of the magnet stopping the rotating magnet and pushing it in the proper direction.
