If you haven't done anything to the clock between the first video and the second, then the two cam disks--the lumpy one and the round one with the single pin--are slipping on their shafts. There are two setscrews on each, and they can indeed get loose.Here is what it is doing now, arrrrrghh!
Looks like the chime locking cam is too far advanced. The pin should be at the bottom of the valley, approximately in the center when the chime stops. The way the clock is set up now, the pin that rides on the cam is moving up the ramp before the chime train locks.I have puzzled over this for a week and can't figure it out on my own. The lift levers are raised but it never goes in to warning, either for the chime or the strike. Here is a video.
Appreciate any assistance!
But I like Willie X's analysis as well: the Chime 3 and Chime 4 wheels wear out their pivot holes in these Hermle's, and that will allow the cam disks to wobble enough to mess up the chimes. In point of fact, the clock may have both problems. I've bushed quite a few of these, but I wonder if Butterbearings wouldn't work better on these fast, heavily-loaded wheels.Something could have slipped as already mentioned by kins.
When the chime is stopped the warning pin should be at 11 o'clock and the chime sequence disk pin should be centered in the bottom of one of the troughs/gulletts.
The train cannot be released because the chime assembly is out of sync. The chime correction lever (hook) will not let go of the locking pin. Only on the high lift does the train release but does not stop until the correction lever drops to catch the pin again on the 3/4 chime.In your video at post #5, the train should release as you pass each quarter. But it only releases on the 4th qtr, when the lifting piece is raised by the tall lobe on the center cam. The other three lobes aren't raising the long lever high enough to release the train.
Well . . . it wouldn't be the first time one of my clocks wouldn't run because I failed to wind it, that's for sure! This one is wound, all three trains, let all three down and rewound them just to be sure a spring wasn't sticking. I'm guessing there is more than one problem. Seems if the levers are raised manually it ought to run but it doesn't.If the train doesn't run even if you raise the long lever manually, you have more than one problem: (1) Not enough lift from the center cam (see video); (2) Even if there were enough, it still wouldn't run.
Are you sure the mainspring is wound?
It will not start manually lifting any of the levers. I think I'm just going to have to sit and examine this thing until I find out why it won't go into warning. I flick the fly on either side of the movement, they turn freely but will not activate the strike or chime train.Can you manually make the chime start by lifting the long lever as high as it will go and flicking the fly wheel or finger pushing the warning wheel?
Doug I have read through some of the posts again but didn't find out what the starting point is. Is this a movement that just stopped working, or is it one that you took apart for servicing and now it doesn't work. If you did service it, did the strike and chime work before?
It looks like it is in continuous auto correct mode.
