Clock chime went insane

[bsg]

Hi,

I restored and had this clock for a couple of years, and now all of a sudden the quarter chime will not stop. We did just switch back from daylight savings, so I moved hands backwards an hour. Did I mess it up by doing this? Here is a video:

Thanks in advance,

Also,

I just noticed this piece of metal laying at the bottom of the case. Am I right to assume that this was attached to a wheel somewhere as a stop, and now it is broken and that's why melody keeps running?

Still, did it break due to me moving hands backwards, or just due to age?

And then, how do I fi it?

Sorry for sounding like an idiot.

Yes, It is the stop pin for the chime. It goes on the cam on the top right. The small round one with the hook above it. You can probably find one at the supply store.

Thanks!

So was it due to me moving hands backwards, or just time?

It broke off the back of the chime stop disc and probably just coincidence.

That's the old style stop disc and no longer available (as a new part) but the old one can be repaired by removing the rest of the broken pin and replacing it with a small tapered steel pin. Filing the leading face of the new pin flat, radial to the shaft, will make for good action.

This is a very common repair with lots of prior post. Search 'repairing Hermle chime stop disc'. Willie X

Does the pin have to be hardened, or can I make it out of e.g. filed down small nail?

 

[Willie X]

It needs to be slightly tapered and soft steel. Regular tapered clock pins are good. Willie X

I'm not sure this will fit yours but it is all brass. No pin to break off.

 

[Willie X]

That's a later design and won't fit the shaft. Old junkers are everywhere, so it shouldn't be to difficult to find a good replacement. Repair is a good option but not especially easy. Willie X

Turning it backward may not have caused the break, but for me turning backward is just a recipe for disaster down the road. Even when the manufacturer says to do it I don't recommend it.
My method in Autumn is to set a timer for one hour, go through my clocks in order, stopping each one. One hour later I start them again in the same order. Works out pretty well with only a few seconds one way or the other in time change.

Got a junker of ebay, took a part from it, replaced and it seems to work just fine. I was afraid there is a particular orientation on the axis, but apparently it is self-regulating, so doesn't seem to matter. Thanks a lot for the help!

There is, but maybe you got lucky.
