Can someone explain about the mechanism in this folk toy:
See Video here: A "penny toy" of around 1900.
It has a spring and it converts linear motion in to rotational motion ( that drives the acrobat). Further the rotational motion is possible both anticlockwise and clockwise.
What exactly is going ne? I believe the mechanism is not uncommon and someone from this background could throw some light.
Thanks in advance for your help.
