  • Patent number: 5190492
    Abstract: A mechanism for dolls which allows for crying, movement of the lips and swivelling of the eyeballs. The mechanism includes a control circuit and timing element which is connected to a switch placed in the mouth of the doll, a magnetic field detector placed in the proximity of the mouth, a voice apparatus, and a motor attached to a mechanism for moving the lips and eyes. The latter mechanism consists of an eccentrically mounted shaft which is attached to one end of a spring having its other end connected to a piece that ends in the shape of an arrow-head connected to the doll face in the proximity of the mouth of the doll. A pacifier inserted in the mouth of the doll, opens the switch to maintain inactive all the devices. If the pacifier is removed the voice device is activated. A bottle having a magnetic element can be inserted into the mouth, and operates the magnetic field detector to start the motor and operate the lips and the eyes.
