    Hello all, hope you are well. What is the escapement called where the escape wheel also serves as the pallet? I have run into quite a few of them. the ends of the wheel are turned upward, and there are more than on a regular escape wheel. It spins and must catch a roller jewel, or something else on the staff. Since i am still working w/ broken watches I have not seen one of these work. I figured many of you would know all about this. Thanks for any help. Stay well…………………….b

    Hello all, w/out a picture I will make another try. What would normally be the escape wheel has the “points” curved upward (like the stylized lotus flower) and connect directly w/ the balance. There is a notch in the balance shaft where the pointed parts of the wheel must strike the shaft. I have seen a lot of these lately. take care…………..b

    Hey b, i will try again, pictures will realy help out ;) , But as you said @watchthebear wrote:

    , or @watchthebear wrote:

    would almost sound like a “verge” escapement, but then again when you said, @watchthebear wrote:

    There is a notch in the balance shaft where the pointed parts of the wheel must strike the shaft.

    sounds to me like a “cylinder” escapement. which when you said, @watchthebear wrote:

    starts to make even more sense, but when you said, @watchthebear wrote:

    (like the stylized lotus flower) and connect directly w/ the balance

    😯 I had no clue, BUT then again that is usually the case, so in my limited knowledge and the desire to help others out, my best guess would be a cylinder escapement. I found a small book on escapements by, F.J.Britton called “the escapements” their action, construction and proportion. very inexpensive yet yields good information, I am sure there are many other books on escapements and the theory behind each and they would be good for any of us to get ahold of. :D Keep on keepin on, William
