That is neat. I would like to see a video of that in use. Good find.

Yeah me too! It almost looks like a joke, but maybe it really does work. I'm trying to figure it out. It must have a couple of cams on either end, thats the only thing i can figure.:dunno:
 
It's pretty cool in action... the bent fingers pump up and down. I will see what I can do about posting a video.
 
To XALKY.
There is no cam inside. I have seen this explained in a book years ago.
The 'fingers' pumping up and down provide the rotation.I can imaging
that they must be quite stiff,almost unbending.
My 2 cents

I can visualize that now. I still want to see it in action. I wonder how much torque you can put on it before you twist it up?
 
I have to admire those thinkers of old. now everything is so homogenized as to get boring.
That's why I like this site and you creative folks so much. As I always say "think out of the box".

That's interesting. Google "Hobson's Coupling" and "Elbow Engine" to see other applications of that action.
