- The recoil escapement of a Birge, Peck & Co., Bristol, Connecticut shelf clock ca. 1850 - 1855. Shows the escapement with too much entrance drop and then the correct drop.

This clearly shows how the wheel is gently nudging the fork to transfer energy to the pendulum. Thank you 🙏
This is exactly the kind of thing I would not quite grasp without something like a video. I'm a very visual person. This will certainly help the next time I need to make any verge adjustments.
Very useful and clear but would be clearer if the text just appeared at the bottom of the screen.
Thanks so much! Been "mentally" designing my own clock, and the escapement seems to be the hardest thing to really understand. That helped.
Excellent and most usefull clips, Many thanks.
So simple yet so unknown to so many.
If one goes to the "Setting" icon at the bottom of the TH-cam screen and selects "speed", one can slow the excellent closeup down to the lowest setting and feel the action. Remember, the wheel is driving the pallet! not visa versa.
@veritasottawa It is a recoil escapement. Deadbeat and half-deadbeat (or semi-deadbeat) escapements have separate locking and impulse faces. This escapement has only one face on each pallet.
Super! Thank you very much!
@pennyf9 On most of these, the speaker is mounted to the bottom or back of the case facing outward, making the sound project well. Clocks with internal speakers don't sound nearly as good.
good demo
Another simpler way of describing this, is that the escapement is too shallow and needs to be deepened to improved the action or swing of the pendulum. By deepening the escapement it also makes it easier to get the clock in beat. :o)
Galileu; Thomas Mudge around 1754, and improved by Abraham-Louis Breguet (1787), Peter Litherland (1791), and Edward Massey (1800).
@pennyf9 It is a Hermle battery operated chime clock.
Good video sir
If there is too much or too little, will this have any adverse effects on the gear - excluding the effects on the pendulum??? Making sure that the one I own and repaired does not do something funky ;p . Thanks ^^ !!!~
What clock is chiming at 0:33? it sounds nice.
I wish the text wasn't in the way of what we need to see.
@Clockhistory what is the name of the clock? Wait, its a speaker? really? I thought it was chime rods.
@Clockhistory really? Its battery? wow, not bad for a battery operated chime clock.
does excess entry drop makes clock run faster ? i have mauthe movement, bob of pendulum is at very bottom of the rod, and still gaining time 5 minutes in hour, tks
Do you have a picture of the movement
I really don't understand. It looks pretty similar to me. Maybe less shock after adjustment
👍
I can't get the escapement on my clock properly adjusted. Its either too tight and the gear won't turn, or its too loose and the gear flies.
Does anyone have any suggestions?
Thanks :)
Look for "how to adjust the beat on a mechanical clock".
It should not go tick tock....tick tock.... but should go tick...tock...tick...tock. if its not tick tocking in a nice pattern you need to adjust the beat.
Mark on a piece of tape where pendulum swings. Mark center and where it ticks and where it tocks. Out of beat clocks tick
Way to one side then tock at center instead of equally far on the other side of center.
Good grief!
I've been searching Google AND here on TH-cam all evening to see if I might find someone with a similar problem.
I'm struggling with what seems to be the same issue on my 30-hr. weight driven S. Thomas half column clock.
I have learned that the part I'm needing to carefully adjust is called the "Pallette Cock."
Sure hoping to learn how this might be adjusted properly!
Alicia Brandt...
Same problem; either the pallet/escapement gear "Spins" too "Loose," or "Locks" up.
Hope you've by now learned how to solve this...
This is a half dead beat escapement.
