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.

What clock is chiming at 0:33? it sounds nice.

[Clockhistory]

@pennyf9 It is a Hermle battery operated chime clock.

[pennyf9]

@Clockhistory really? Its battery? wow, not bad for a battery operated chime clock.

[Clockhistory]

@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.

This is a half dead beat escapement.

[Clockhistory]

@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.

@Clockhistory what is the name of the clock? Wait, its a speaker? really? I thought it was chime rods.

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.
