    Who's up on the Schatz W3 movement. I've just acquired a Schatz triple chime mantel clock and one of the selector positions is to silence the chimes but I don't see any device that arrests the train.

    I don't know about Schatz specifically, but there are some movements with "silent" levers that move the chime drum to an area without any pins. This allows the chime train to continue to run and trip the strike train at the hour. The strike train would then have its own "silent" lever.

    Modern German movements with silent features which arrest the chime train completely will silence the clock and no striking occurs.

    Yeah I thought about that but there is no blank area on the drum. The only thing I can think is the selector arbor goes through both plates directly under the stop wheel(works like an Urgos) and thought there may have been a lever that swung over in the path of the warning pin when the silence option was selected. This poor ole clock has been in the hands of monkeys with tools so I will be busy un-doing their handy work.

    Hey Jay-

    I've seen some where a taper pin was inserted into a hole in the selector arbor and, when the arbor turned, the taper pin would catch the stop pin, warning pin, or butterfly.

    Can you post a photo of the movement?

    Here's the beasty,purdy thing huh! Love that engine turning!

    If you look in the 4th pic down past the stop wheel you can see the selector arbor,there's no holes in it.
    If there was a lever it would have had a collet and screw but I don't see any screw tracks either unless it's on the bottom. The direction of rotation works out,as you lower the selector the arbor would rotate away from the stop pin. The lever on the front is just a pointer,the selector is the lever on the back.

    Interesting! I'll see if I have an example of this movement laying around and try to give you a better answer. In the mean time, maybe someone else can help...

    Looking at the third picture there looks like a bend in the bottom of the lever that might push the drum in far enough that it is suppose to disengage the drum gear from it's drive gear when in silent. Is this possible?

    Randy, wouldn't that throw the drum out of sync, requiring someone quite knowledgeable to reset it?

    Yes sir I suppose it would, I was just looking for some off the wall possibility because I knew Jay would probably see it if it was something more familiar.

    Schatz and especially Junghans engineers came up with some pretty unique(goofy) solutions.

    I wonder if the lever somehow disengages the drive wheel on the back side?

    It might be possible for that lever to put enough pressure on the arbor to stop the train from turning, which is basically all that is needed to silence the chimes.

    Hi Jay
    How about a bottom shot of the drum. I still think there is
    a blank track on the drum and it works like David says.

    Here's a good shot of the barrel.

    w3 009.jpg
    This is the position of the barrel in the silent selection.

    w3 011.jpg
    This is St. Micheals,only the lever has moved,the barrel is still to the far right.

    w3 012.jpg
    This is Whittington and the barrel has been moved to it's center position.

    w3 013.jpg
    This is Westminster and the barrel has been shifted to the full left.

    Hey Jay-

    I didn't find one in my inventory and the only way I can see that the lever in the "silent" position would actually do anything is if you rotate the collar on the back plate for the chime release lever so the set screw flirts with the select lever extension. So, when the lever is in the "silent" position, it will lift/hold the chime release lever and nothing will happen at the quarters.

    Let us know if that works :).

    Check this out! After you mentioned that I did a google image search and found this;

    The regulating arm is kind'a in the way but that screw is oriented just as you suggested. Kind of a silly way of getting it done but cost effective seeing they just got hammered by the fall of the torsion clock era.

    David,if your ever doing one of these you set it up so that it's holding the lifting/warning lever just as it touches the cam follower/release lever. That way it holds the chime train in warning. The screw in the collet is offset and goes towards the plate or it makes it hard to pull out on the selector lever,it gets hung behind the screw head.Yeah,it was on backwards too:screwball:.
