Letting YouTube do the culling for you.

I had been searching and learning about clocks and specifically the escapements. Quite frankly I didn't know one escapement from the other. But YouTube tracked me and when I logged on there was all the escapements I was looking for. 13 to be precise. Amazing. It culled the clock world for me. So here they are.
1, Deadbeat escapement
2. Club tooth escapement
3. Hermie carriage clock escapement
4. Pendulum lever system escapement
5. Grass hopper escapement
6. Single pivot grasshopper escapement
7. Galileo's escapement
8. Double pin wheel escapement
9. Sir Edward Beckett Dennison three legged escapement
10. Involute escapement
11. Two wheel walking escapement
12. Beeler escapement
13. Recoil clock escapement

Thank you YouTube It's took me 15 minutes. Well collectively two hour over several occasion of me culling to get a feel and then it figured out what I wanted and wha la! I got it.
