Adjusting speed of Herschede 8 day model newton

by Kirk
(South Central Wisconsin)

My clock runs fast. It gains enough time that it has become more like a three day clock.


The chimes play much faster than they used to.

Is there a way to adjust the speed of the movement?

Hi Kirk

To adjust the speed of the clock you adjust the weight at the bottom of the pendulum.
When you let the weight slip down, the clock will slow down.
You will have to repeat the process to get the clock running the right speed.

I recently purchased a Newton at a resale store. It has had a rough life. I am in the process of restoring and can find little information on the clock. Could you please post pictures of your clock?

Hi Kirk,
If the weights are hung in the correct order, then your movement needs to be overhauled. I just sent mine out to Mark Butterworth @ butterworth clocks. He invented a bearing that inserts like a bushing so that your pivots never wear out again. Plus the meshing and smoothness of the running movement is better, in my opinion, than a new one. See the problem you run into is that if your movement is the same as mine, it is a special edition Urgos that is no longer made. And, if you put in a different movement, you risk hurting the value of your clock. All I can say is that I am very happy that my clock is all original and running beautifully.

starstarstarstarstar 		correction of weight information.. NEW
by: Anonymous

Yup. I messed up. The first weight is the Strike Train weight, this is the part of the movement that counts the hours. In the center is the Time train weight and it is responsible for powering the hour and minute hands and is regulated by the pendulum. On the far left is the Chime train weight. It is the heaviest weight and is responsible for powering the train that moves the hammers to strike the melody. most common is 4/4 or the quarter hour chime. Some models only play the melody on the hour and the half hour is struck by a single chime, like a mariner clock. Others are called bim bam and count the hours with one strike on the half. Most bim bam are key wound, but hermele makes a few with weights.

It is more likely that the weights are hung in the wrong order. on the bottom of the weight shells is on which reads CT, this should be on the far left as you look at the clock. the other two are the same weight and don't matter, but if you are wanting the information anyway, the St, is on the left and the weight marked TT is in the center.


So is the ST on the left or is the CT on the left? I think Chris meant to say that the ST is on the right, I think?

Two things to note: Temperature affects speed. The clock will run slightly faster when warm as the bearing plates expand more relative to the pinions and gears. Second, clocks run faster with wear. If you can't regulate your clock to within a minute or so a day, then the movement may be in need of a full restoration, in which it is disassembled, bushed, re-pivoted - where needed- polished, then reassembled and lubricated. You can tell that the second case is true when you have the timekeeping close to right, but still have to rewind, or raise the weights more often than it used to. Now, for an eight day clock that is around 40+ years old, then raising the weights at 5 days is typical, but the movement does need attention. If you wait until it reaches every other day or two, then you increase the likelihood that more damage to the movement will occur, sometimes meaning that it can't be put back to "perfect." (without a ton of money)...
