    Default Rack and Gathering Pallet Issue

    I'm working on a German Gata Westminster chime movement. The rack and gathering pallet seem not to be working properly. Essentially, the pawl on the pallet does not seem to be lifting the teeth of the rack high enough or the locking piece on the "J" shaped lever is not locking on the rack. The rack teeth do look worn. I've included a picture.

    Your thoughts on how to make this right?

    Thank you,

    Dennis

    That pin looks so close to the shaft that it appears there would hardly be any lift during the period it is engaged with a tooth. Is the pin a replacement and is it in the right place? It is hard to tell from the photo.

    The pin might be bent, too. Try pushing it toward the edge of the GP more. The teeth do look worn, but not enough to cause an issue. It's also possible that the GP is positioned wrong, and lifts and releases a tooth before the hook can grab it. Double check that the hammer lever falls just as the train stops.
    A man with a clock always knows the time. A man with two clocks is never sure.

    Just for my own education: I have never heard of the German clock name Gata before. Please could you post a photo of the movement and (if possible) the name/mark?

    Thanks in advance.

    It just came to my mind that perhaps you meant to write GALA? (That might be Thomas Ernst Haller or Müller & Schlenker).

    Hello folks,

    I'm enclosing a few more pictures, one containing the manufacturer's name.

    The pallet and pawl look to be original. The pawl has not been moved, as far as I can tell. I bent the pawl a little toward the edge of the pallet and Bazinga! The contraption now works as intended. With perfect teeth, the rack and pallet should work with the pawl in the original position. If need be, some day I may have to address the worn rack teeth.

    On to making the adjustments to insure proper sync, etc. I have to put the clock on the stand and try to figure that out.

    Thanks,

    Dennis

    Thanks for posting the photos of the movement - and now we see it's not Gata, it's GUFA (Gütenbacher Uhrenfabrik KG).

    Mystery solved!

    Glad it's working, but I can't figure out how the rack teeth would wear much, if at all?

    Gufa? I guess that's why I couldn't find any references to Gata. Good Catch. Thanks.

    You might check for a worn bushing/pivot hole at the gathering pallet arbor. Not uncommon to find wear at this location and if bad enough it can affect the pallet-rack engagement.

    It appears as if I might need some help setting up the chime and perhaps strike sides. Are the pictures that I've posted enough, or will other pictures be needed?

    You'd need to tell us the issue.
    The front plate shows most things but it looks to have an
    internal auto correction lever. That normally catches after
    the 3/4 hour chime plays.
    You need to check that you have warning on both strike and chime.
    If the chimes are regular Westminster, you adjust the drum for descending chime
    on the first 1/4.
    Stops for the chime can be set by loosening or removing the chime
    plate and trigger it. The strike is similar. You pull the gathering pallet.
    The auto correction may be a pin on the back of the chime plate or
    internal. If internal, you need to trip it until it catches and then set
    the chime plate between 3/4 and the hour. I a pin, it is already
    right.

    At the end of the strike, the pin on the rack hook should be nestled in the hollow of the GP; hook should be completely under rack.

    Have a look at Chime Clock Basics.

    The strike side has no provision for a warning run.. The pin travels from one stop to another. The warning run as now set up on the chime side is rather long, perhaps 340 degrees. Seems to be ok, though.

    It's on a test stand now. I will need to sync the chimes.

    I don't have the clock in front of me but usually there is a warning
    run on the strike side.
    When the long lever is lifted by the bump on the locking plate cam,
    you are saying that when the rack hook is lifted the gathering
    pallet doesn't rotate a little?

    There is movement, however it is preset. The warning pin simply moves from one stop to the other. The run is between the two stops and cannot be changed.
