I just posted an image and link for an Arnfield escapement built in Meccano, in its own thread.  Maybe it will help?

There is a nice animation of the Arnfeld at http://images.google.com/imgres?imgurl=http://www.clockmaker.it/fotoorologi/regolatori/42/Arnfield3.gif&imgrefurl=http://www.clockmaker.it/ingle42animaz.htm&h=375&w=500&sz=292&hl=en&start=4&tbnid=LJr0zhhZDyLMLM:&tbnh=98&tbnw=130&prev=/images%3Fq%3Darnfield%2Bescapement%26svnum%3D10%26hl%3Den%26lr%3D%26rls%3DGGLR,GGLR:2006-06,GGLR:en%26sa%3DN

There's the short version of that URL.  And, you're right...that is a VERY nice animation.

The Meccano diagram I mentioned above is at http://www.bealltool.com/clockforum/index.php?topic=252.0
