    I don`t have a camera to take a picture. I have a A Schneider regula cuckoo clock with musicbox and rotating dancers. circa 1960s It was missing the chains . Got chains but cannot figure out how to position the chains for the musicbox/ spinning dancers. There are a double pulley /gear attached to the musicbox and a double pulley/gear above the music box and a single pulley/gear for the dancers. I`ve tried different combinations but nothing works. I do have the fly open and free to test the musicbox but I just don`t have the position of the chain to grab and turn the various gears./pulleys. I can just wrap the chain around the music box gear and it works fine but then don`t have the dancers attached to the chain.

    WIN_20171116_16_55_56_Pro.jpg got a friend to take a pic. I know it`s a terrible picture. Perhaps someone has a similar anton Schneider setup and can take pictures of how the music box chains should be around the dancers, and the other double pulleys/gears. Thanks

    Can't take a pic right now, but it's not one continuous chain that runs everything. There should be one 'loop' of chain that goes around the fixed chain gear on the end of the music box arbor up and around the dancer table. And then another chain that goes around the click wheel to power everything.

    Not sure I quite understand. I thought the musicbox dancers worked off one continuous chain. Your replay suggests That I need 4 chains --1 for time, 1 for cuckoo , and 2 for the musicbox and dancers. I`ve never seen a 4 weight cuckoo, so will wait for your pictures to see how this works.

    There is no weight on the 4th chain. It is a closed loop that goes from the music box up to the dancers. Hope the pic helps.

    I recall that some used an "o" ring type belt for the upper piece. I haven't seen that particular movement.

    What Chris said. The weight chain hangs on the MB, just like the time and cuckoo call chains. And the dancer platform is driven by a loop of chain, or rubbet belt.
    Note, if a chain loop is used from the MB to the dancer platform, it needs to have an even number of links and every other link has to be in the same plane. IOW, any twist in the chain can cause an intetmittent stoppage. An "O" ring type belt needs to be a snug fit but definately not tight.

    Four chains, three weights, two sprockets on the drum shaft. One chain is a closed loop. It goes from one sprocket to the dancer table. The other is a regular chain with a weight on one end. It goes over the other sprocket, and drives the music box and dancer table at the same time.

    Chris D's pic shows it perfectly.

    Thank you for the pictures and instructions. It now makes sense. But seems like a poor design and pretty tedious to get the closed loop chain just right.
