ABSTRACT:
Toy apparatus is provided with delivery structure constructed to simulate a natural birthing process by imparting slow pulsating delivery motion to fetal dolls as they exit from a simulated birth canal. Such delivery structure includes an elongated cylinder which constitutes a birth canal, a piston mounted for longitudinal movement within the cylinder, a spring that biases the cylinder forward to push fetal dolls in a delivery direction through the open front end of the cylinder, and retarding structure acting on the piston in opposition to the spring. The retarding structure includes a seal function alloy engaged with the cylinder and carried by the piston, and metering structure to create a vacuum behind the piston by limiting the rate at which air is drawn into the cylinder behind the piston while the latter moves forward.
