Recoil Escapement
Posted: Fri Sep 06, 2013 2:58 am
I would like to suggest one more item to add to the list. That is a Recoil Escapement. The Recoil Escapement is, I believe, an American variation of the dead beat escapement. The difference is that there is no lock and the escape wheel teeth are allowed to slide along the pallet face for a short distance after the actual "escape". This is a much more forgiving escapement than the dead beat. If you've ever hear the uneven beat of a cuckoo clock you'll hear what I mean, that unevenness is because a recoil escapement has been used.
Since the math of calculating the pallet angles is identical the conversion from dead beat to recoil should be "fairly" easy (can you can tell I'm not a programmer?) The only real difference is in the length of the pallets. The teeth of the escape wheel also "lean" away from the direction of rotation instead of "into" the rotation as they do in the dead beat.
You're probably a very long way from implementing new suggestions but I though you might put it on the list. I can send you a write up from a 1906 book on the escapement if that would help.
