<p align=LEFT> <A HREF="doll6.html"><img src="fig/h5.gif" alt="doll5"></a> The mechanism for turning back. You can see a small wheel at the bottom left of the photo. The wheel turns along with the handle pushed by a cam mounted to a driving wheel. As the left side of the handle is pushed to the right by the cam, the wheel turns right with the handle. It is just like the interlocked combination of the front wheel and handlebars of a tricycle. The mechanism for turning at predetermined intervals. The handle is pushed in orderly sequence by the cam. The doll turns right when dents in the cam catch, and it moves straight when the dents do not catch.
