Ratchet mechanisms

Although ratchets are mentioned as one of automata mechanisms I"ve hardly seen one automaton made with this mechanism. Does anybody  know an automata toy (paper or not) made with this mechanism? I would like to know, really.

Hi Hugo,

I d'ont know ift that is exactly what you are looking for, but you should have a look at Walter Rufflers hompage:

http://www.walterruffler.de/index1.html

especiallly at:

http://www.walterruffler.de/Galerie/Ruffler/sperrad.jpg

You can build this and four more automata out of :

"A Handbook of Paper Automata Mechanisms" wtitten by Walter Ruffler

ISBN-10: 1899618589
ISBN-13: 978-1899618583

Should be available at amazon or any other (online-) bookstore.

Best wishes

Ratchet

Thanks, Max for pointing me the link. It IS what I'm reffering to. I discovery that the model Counting Sheep from Rob Ives also uses a Ratchet. It's nice and kind from you showing the links. Thanks again.
