• Upcoming updates
    Over the next couple of weeks we will be performing software updates on the forum. These will be completed in small steps as we upgrade individual software addons. You might occasionally see a maintenance message that will last a few minutes at most.

    If we anticipate an update will take more than a few minutes, we'll put up a notice with estimated time.

    Thank you!

I have cleaned and reassembled the movement, the first one of this manufacture I have seen. My problem is synchronizing the lift levers for the bellows with the lift lever for the hammer. When the movement stops, the short lever is partially raised so the bellow does not drop as it should. How do I synchronize the movement so it works properly. Thanks, Rod.

For the record, GM angem is not a make of clock or a type of clock.

GM angem is an abbreviation for Gebrauchsmuster Angemeldet, which is a German utility-model patent that has been applied for.

Use of the "GM" abbreviation (for Gebrauchsmuster ) is typically post WWII.

Regards.

What I need know is how the movement is to be assembled so that the cam, the pin wheel, and the count lever all line up so that the 2 levers and the strike lever are synchronized. The movement is the same as others which are shown online. Thanks, Rod.

What brand of movement is it? Herr? Schatz? Regula, and if so, what model? Baduf? Schneider? Euramca? Rombach and Haas? Hekas? Trenkle Uhren? Other? We need to know this so we can help you.

It is a G.M. Angem 1 day cuckoo clock movement. Rod.

Rod,
I don't think anyone here can help you without a photo of what you have there, along with a close-up photo of the problem area.

Usually the lift cam is friction fit and can be moved without taking the movement apart again. It sounds like yours just needs to be nudged forward a little. Newer movements have a screw on the cam that can be loosened to allow it to turn.

I did a Hubert Herr from the 50s and the cam didn’t seem to be friction fit. It wasn’t fun.

Rod,

There is no such thing as a G.M. Angem movement.

See my post, above.

You will need to provide pictures.

Regards.
1) On the back plate of the movement is "G.M. Angem"
2) On the Forum sites are MANY pictures of these movements.
3) Other folks have asked questions/made suggestions re these movements. So there seems to be much info about these clocks.
4) I just need to hear from someone familiar with these clocks to assist me.

Thanks, Rod.

It is not. See post #2. G.M. Angem. is not a make, as was clearly explained by new2clocks in his post.

Unless we see a photo of the movement no one can properly help. Otherwise you are just saying 'this is a movement by patent pending'.

Rod,

Are you unable to post photos? My crystal ball is still in the shop ... :)

With no real conversation, your thread will go dead pretty soon.

Hi Willie, I noticed your threads as you assisted other folks with these G.M. Angem movements. (So there are G.M. Angem movements). You have offered replies to their asks. All I need is to figure out a way to synchronize the lever movements when assembling the movement so the levers drop properly when assembled. You had pictures of these movements. If I am wasting your time, you do not need to reply. Thanks, Rod.

Don't get riled, Rod. Folks want to help you, but we're shooting in the dark. Pictures can be added to your posts by using the "Attach files" box in the lower left corner of the posting box ;)

There are all sorts of things, including clock movements, marked 'Pat. Pending', which is what G.M. Angem. means.

This does not identify the maker or the model.

Thanks, Rod.

I opened the movement and rotated the cam wheel a tiny bit, reassembled the movement and bingo, the clock is working well. Thanks, Rod.

Glad you got it, Rod! We hope you'll stick around, and have another challenge for us :)
You never have too many clocks :D

Hello
Probably I'm trying to synchronize the same model of cuckoo movement. I've disassembled the movement, cleaned, oiled and assembled again. The problem I have is synchronizing the hour number. I think that the problem is to know the procedure of adjusting de 2 bolts marked in the pictures. Any help would be appreciated.

I've got plenty of pictures and I know how to post them. I know that "G.M. Angem" is not the name of the manufacturer, does anyone has more information about the manufacturer?
How could I know when it was manufactured, may be in 1960's?
(Pictures before disassembling and cleaning.)

From what I've looked at in The Clock Repairer's Bench Manual, you appear to have a Regula 21 with plate dimensions of 66mm H x 71mm W x 17.5mm D and it should have 250g weights for time and strike. As to the age of it, I can't be of much help there. Hopefully Willie or someone else who commented above will have better insight as to a possible date of it.

Thanks rjdj2000

These are the dimensions. They are a little different from the Regula21 that you mention.
I'll buy the book you mention. I'm still trying to synchronize the cuckoo without success.

The only one that comes close to the dimensions you give is a Regula 25 according to the book but I am not sure if the back plate matches. One of the others that knows more on cuckoo's than I do may chime in here to help figure this out as they have in the past.

That is a regula 21.

It's usually a simple matter of working with the lower two mesh points, in most any one 1-Day cuckoo.

When correct, the hammer tails and the cam that pushed out the birdie, will be in the 'do nothing' position when at normal stop.

If someone has monkeyed with the wires/levers all bets are off. :)
