Does anyone know how to set up this chime sequence? I thought it had an auto-correct function but if it does It's not working. I just today got the motor working properly so now I can watch it go through the sequence and maybe learn how to set it but any information would be appreciated. Thanks, Danny

Silverdollar Productions shows the Revere service manual on their website and that manual may include the information that you need. Here's the link:

Pat, thank you very much. That is exactly the clock I'm working on. This is a very complicated mechanism. I think I was getting close but this manual help me get right in just a short time. Have you ever set one up?
Thanks again, Danny

Danny,
No, I haven't set one up. I do have several clocks with that type of movement, including one running very well in my living room right now.

Thanks again, Pat. That was the answer I needed. I was able to get it set up but still having some issues with the motor. I think I can it back in working order.
Have a great day. Danny

Hello, Will. This motor is very hard to hear when it's out of the movement. It makes a little bit more sound when under a load.
Are you familiar with this movement? It is very different from any I have work on. It has only two pivots in the train. Most gears are on posts. The chiming mechanism has more pivots and is very complicated. I'm having trouble getting it set up. Also, the motor gets jammed when installed. Out of the movement, it runs well but installed it seems to jamb when under the load. I'm looking to see if it is the motor or the movement jamming but I think it's the motor.
I have almost finished the Hamberg American. Stay tuned. I'm selling it for what I have in it. Initial cost 90.00 and hours of repair, 3,751.00
God bless, Danny

It’s probably the rotor. They can be rebuilt but it’s not easy. David Labounty has a tutorial on his website explaining the rebuild. I send them out. davefr, a member of NAWCC , is the expert on these. He has rebuilt ones or will rebuild yours.

Do you have any idea how much he charges? From what I can tell these clocks don't bring in a lot, under 100 for the common ones. It's all about sentimentality.
Thanks for the links. I think I'm going to try to repair this one. I have the owner's consent. I'll let you if I do and how it turns out. Thanks, again. Danny

Contact Dave (davefr) and tell him what rotor you have and he may already have a rebuilt one. He sells them reasonably. I don’t know what those sell for these days.

I'm back to this Revere now. I got the service manual from eBay I think it was.
1629661457764.jpeg
It is very detailed in the description of the parts but I'm unclear on just how to set it up. In the book it is called locking disc. I'm reluctant to show a picture of the page for fear of copyright infringement. Is that permissable? I can't find a copyright warning in the book.
I did as the book says and lined the holes in the chime wheel and put the rod in and tightened the set screw on the locking disc. I ordered a rebuit B3 from Dave over at Telechron. It should be here in a couple weeks so I'll be turning and looking from every angle.
Does anyone have a simple explenation of the initial set up? I'm thinking 1234 hammers on the first quarter.
Thanks, Danny

My question has to do with the relation of the locking cam on the front bottom right and the hammering wheels. It also strikes using that geared wheel on the outside of the chime mechanism.

Why is the hammer tail spacing uneven in photo #4? Shouldn't they all be more or less centered on the pin?

That big correction wheel (external) on the front of the movement often has a worn bushing.

There is a replacement (much more powerful) rotor available. This rotor will require various mods, some more complex than others. It also normally runs hot and is a bit noisy for my ears. Merritt's P-1492, I've replaced a lot of B-3 rotors with this item and never had one come back.

I think that's by design because the pin barrels go between the outside tails (right and left.)
Thanks, Willie X. I've had it apart and put one bushing in but I don't remember if it was that one, I'll check. I've ordered an original replacement rotor for it. I'm just trying to make sure I understand the chime setup. The book is great but somewhat of a puzzle to figure out. Like "pin M contacts lever L and trips gear Y, you know. I'll get there when the motor comes and I can watch it in operation. Thanks, Y'all, Danny
I'll still accept ideas from any that has one.

Yeah, when you have one motor trying to do three things, it gets complicated. Think of it in terms of "this has to start and when it ends it has to set this up over here" There is usually some weird shifting of components that takes place between the chime and strike cycles. I believe it is legal to show a small portion of a copyrighted page as long as you state the book name, author and page number in your post.

What does this indicate? Is it the chime-off indicator?
1631229080094.jpeg
I don't see anything that cause's it to rotate. I didn't get a pic of it before. It has this clip that seems to be weighted to make it stay in position but I'm not sure of that.

It's a power loss indicator.

If you come home from work and see that little hole in the dial has turned red. That means there has been a power loss, maybe a second, maybe hours but you know (at a glance) to check and re-set the time and manually reset the dropped indicator flag.

So, what causes it to rotate to the red? Is it magnetic? There are no levers or anything that I can see to move it. Thanks, Danny

Gravity. The magnetic field created when the power is on keeps the red out of view. When the power goes off it rotates into view.

So, in post #19 pic #2, do I need to use that as the counterweight? There is nothing connected to that component. I'll do a little experimenting with this new info. Thanks, Danny

There's a pin on it that probably needs to be moved to the other side after you get it set. The magnetic field should hold it there until the next outage.

Ok, I'm back at this Revere. Here is the instruction manual I got for this model.
20210927_145129.jpg
The top instruction says to set the hour control wheel. See the top illustration. Figure 3. Now if you look at the pic of the movement you can see that the holes do not line up. The wheels on that shaft are fixed and do not spin in a way that I could move them to line up the holes. See the wire I'm using in the middle of the pic? It's supposed to line up with the hole in the first pinwheel. There's a nut on the back there. Do you think that might be how you would turn the pinwheel?

Thank you, Danny

Where do you get this stuff, Dan? :D
It looks like the notches line up, and that must be significant. Does that train run both chime and strike? Does anything slide in and out as the clock operates?
The setting wire appears to go into the first four disks. From what I can see in your pics, you seem to be on the right track. There should be only one way for all of them to line up together.

Sorry, I miss spoke, the top illustration is for the chime setting.

I'm not sure how it happened but I had to realign the hole in the large front gear wheel with the small hole in the first pinwheel. See post #26. I had to take the chime wheels out and hold the large front wheel and turn the nut until the pinwheel with the hole came around. (scary job) Once I got that back to good I was able to follow the instructions to get the chime and the hour set. It is working great so far and I'm putting it back in the case today. If all is well I will be sharing a final video in the near future. This clock has to be back in Alabama to its 96-year-old owner before it's too late. :rolleyes:

Does anyone know if these movements had hammer springs? The manual I have doesn't show them are even mention them so I assume not. This hammer system is very weak and is easily upset. It runs slow and just isn't very loud. I'm wondering if there is something I can do? Thanks, Danny
