  • Patent number: 4224760
    Abstract: A bubble-blowing doll has a body which includes a trunk, two arms and two legs movably connected to the trunk, and a head also connected to the trunk and having a mouth opening. One of the arms rotates a ratchet wheel of a ratchet mechanism which, in turn, rotates a pulley about which a rope is wound during the operation of the ratchet mechanism. A bellows is mounted in the trunk, its upper end being stationary and its lower end being movable toward and away from the upper end, and the rope is connected to the lower end of the bellows, while a spring biases the lower end away from the upper end of the bellows. A conduit communicates the interior of the bellows with the interior of a balloon an open end of which is mounted on a reed and a distensible end of which is located at a free end of the reed and at the mouth opening of the head in a deflated condition, and at the exterior of the head next to the mouth opening in the inflated condition of the bellows.
