I dug out a diagram of the Erard action that I'm trying to get a  handle on.  
Any suggestions on regulation of this would be welcomed!   Quentin and Pierre 
have been most helpful.
 
I don't know if the 1821 on the diagram is the year this action was  patented 
or not.  
 
Curious animal, that's for sure.
