Need strike assistance

[bangster]

Remember this clock?

Now I've got another problem: the strike starts before the chime is finished, and I cain't figure out what to do about it.

Here's the setup: the chime locking hook is on the same arbor as the long lever that has the strike warning detent on its other end. So the locking hook and the warning detent fall together when the projection at the chime end falls into the notch of the locking plate.

To avoid my problem, the locking hook needs to grab the chime locking pin and stop the train BEFORE the strike detent releases the warning wheel and starts that train. But that seems impossible, given that the two events happen simultaneously at opposite ends of the lever.

Got any ideas?

Interesting. There should be enough of a gap when the chime locks, releasing the strike, to not have any striking while it still chimes. It should be physically impossible to have striking while it chimes, unless the strike warn lock isn't locking. Can't tell without having the movement in my hands where your problem is, but it is minor.

On the hour chime, the high spot on the locking plate lifts the long lever some more; the rack drops, strike train unlocks, warning pin stops on the detent at the end of the long lever. So far as I know, that's exactly what it's supposed to do.

Meanwhile, locking plate continues to turn, chime continues to play. Thingummy drops into notch on locking plate, strike train is released and starts, but chime doesn't stop RIGHT then. Plate continues to turn (with thingummy bottomed in notch) until chime lock hook snags the locking pin: two or three notes worth of chime. If I'm supposed to adjust the locking plate, I can't figure out how; likewise if I'm supposed to adjust the lock hook I can't figure out how. If I'm supposed to adjust something else, I can't figure out what

I tried adjusting the LP so's the leading edge of the notch meets the thingummy just as the pin it almost at the hook, but had no success. Maybe I should try that again.

Bang, It sounds like it's going into strike as soon as the warning lever drops off the lobe,it shouldn't go into strike untill the lever drops into the notch. Is part of the warning lever broken off so that it's releasing the wheel to soon? Take a pic with the rack removed.

Maybe the lever is bent in. Did you have to bend it to get it out of the plates. Some have to be bent and if you don't bend it back you'll get this type of problem... And take some pics Thing a ma-jigger doesn't work well for most Or whatta ma callitOr Thingummy << really

Bang each chime sequence (4 notes) has a gap til the next sequence. Between that, and the pin locking the chime as soon as the lever drops, you should have sufficient gap between chime and strike. Just a little fine tuning on the locking plate, and maybe the chime drum required.

Nope; I didn't make the description clear. It doesn't go into strike until the long lever drops into the notch. But after it first descends into the notch, it continues to play a few notes until the locking hook stops things. While it's playing those few notes, the clock is striking.

 

[Randy Hirst]

Can you adjust the drum forward so it plays the last note just as it falls onto the notch, or will that cause it to raise hammers when it goes into warn the next time?

 

[Mike Phelan]

That's what it should do and means that there's the longest "space" on the next chime before the first hammer lifts.

Bang, on your clock is the chime train locked using the warning pin or a pin or notch on the wheel below?

Sounds as if it's just a timing issue on the count wheel unless something is bent. It should lock immediately when the detent drops into the count wheel notch.

Harold nailed it then. Got 'er fixed yet?

 

[bangster]

Jewels, you're right. Harold and Mike have joggled my brain in the right direction. Adjustment needs to be made on the back side (chime drum side) rather than the front side (count wheel side).

Thanks friends; I shall report back.

(Mike: It locks on the chime lock pin on the next-to-last wheel in the train, when the pin is grabbed by the locking lever/hook. Same pin the chime correction uses.)

I would also adjust the locking plate to have less movement after the lever drops (catch the pin sooner).

 

[bangster]

Yup. Easier said than done, but I shall do.

Sounds to me that you need to rotate the 1/4 hr wheel ever so slighty ccwise, if it is still advancing to the nexr 1/4 hr chime. The strike flirt drops and the strike begins, but the chime is trying to chime the next ,or the 1/4 hr chime, at the same time. Fix the 1/4 hr wheel and you will fix yout trouble,,, good luck TTD
