• 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!

Please see pics. The steel spring that keeps tension on a gear controlling the clock weight has broken. The result is the weight falls to the floor, and the clock no longer functions. Any idea on where I can purchase parts such as this; someone who manufactures these types of parts, or someone who repairs these types of clocks/issues. Thanks for any suggestions!

Sounds like you may be describing the 'click spring'? But the photos don't show anything that looks like a click spring??

I believe Willie is spot on.
The click is the small dog that clicks when the clock is wound. It has a spring that pushes the click into a ratchet wheel to lock the train.
Most likely the problem will be more than replacing that click return spring.
The clock has two trains that have probably been wound the same number of times in the last 100 years or so.
The click assembly on the other train likely is due for service and is due to fail soon.
In addition, the rivet that the click rotates on is probably worn to the point that the click does not fall properly into the ratchet wheel.
It is also likely the tip of the existing click has been chewed up due to not returning properly.
Mauthe may be one of the German manufacturers that used brass ratchet wheels.
Those are prone to getting chewed up as well.
The solution for that is to substitute a steel ratchet wheel.
If so, a modern Hermle ratchet wheel will be a close fit.
Last but not least---That movement is probably worn from many years of use.
It might be time to solve the wear in the rest of the movement to assure reliable operation for another 100 years or so.
That is how I feel,
Dick

Timesavers has a big selection of click springs but I’m not sure they have that one. That is a nice heavy movement and the click springs are pretty hefty. Check their website.

Look carefully at your photo. The point is broken off of the click.
You have more problems than a broken click spring. I stand by all that was said in post number 3.
If you value the clock, find a qualified clock repair person to help solve your problems.
Replacing the click assembly is well beyond the capabilities of a novice.
This board is populated by all levels of repair people.
You may get some bad advice here along with some good advice.
