I commented incorrectly on a recoil click in another thread that I had thought was Fitch's patent, but is really Aune's patent. That got me to thinking about these little mechanisms and what their history might be. Some of us are really fond of these little mechanisms. There can be almost as interesting as patent regulators. What is the earliest patent for a recoil click that we know of? What are your favorite examples? I will post Fitch's patent here and perhaps Jerry will repost the Aune patent here also.
