Bill,
This exact same question was posted several months ago but I don't
remember the sollution that they came to. This is my Idea:
Ok you take two pulleys, pulley (A) is smaller then pulley (B).
You then conect the 2 pulleys via a linkage so that when you turn pulley (A)
pulley (B) continuosly changes directions.
Now you take this two way motion and convert it back to one way and you
have your desired effect.
To better illustrate the conversion of 2 way motion I have uploaded a
.dat file I did't create this .dat, but I did build from it and the model
is compact and works well. If anyone knows the author please respond to
this post so they will get the credit they deserve.

| (...) Thanks - but that's not what I'm after. I want the input shaft to be rotating continuously - and the output shaft to be stationary for some relatively large amount of time - then suddenly rotate for a short time. This cycle should be repeated. (...) (22 years ago, 3-Apr-02, to lugnet.robotics)
