  • Patent number: 4413441
    Abstract: A multiple function doll is disclosed which includes a controlled wetting function. Wetting is effected automatically whenever the doll is placed on a toy toilet. The wetting function is controlled by a pinch valve which prevents the flow of water from a reservoir to a wetting orifice. Placing the doll on a toy toilet automatically opens the pinch valve. The doll also includes a hand clapping function which is driven by a spring motor. The spring motor is in turn controlled by a switch mechanism which permits a child to start and stop the hand clapping.

  • Patent number: 4339889
    Abstract: A multiple function doll having a unitary drop-in internal mechanism including a motor which rotates a cam to cause an arm of the doll to wave and rotates a drive shaft to reciprocate a pump which causes the doll to tear. The simplified mechanism is constructed to provide conduits for liquid from the doll's mouth to a reservoir and from the reservoir to the doll's eyes so that internal tubing is eliminated. The elimination of tubing and reduction of components reduces substantially the tendency of the doll to failure.
