different type of escapement

[watchthebear]

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:

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:

😯 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. Keep on keepin on, William
