They were all important once, until about 1930, but are no longer used for precise timekeeping, just decoration.

The property of a pendulum which made it so is that, for a frictionless pivot and a massless rod with a relatively massive bob on the end, the swing period depends only on the length of the pendulum. Thus designs focussed on those factors.

In practice even the expansion of metal parts due to the heat of the day caused errors, and they could not be used in vehicles or boats. The search went on.

REGULATION TIPS FOR THE 400-day and 1000-day clocks


CLOCK REGULATION TIPS FOR THE ROTATING REGULATOR
These Regulations tips are useful for regulating the rotating regulator. This is to include most 400-day and 1000-day clocks.
The following information is copied from SCHATZ (tm) OWNER'S HANDBOOK.
Time Regulation Tip:
On the top of the pendulum is a disk on which numbers are engraved 1 - 16 and two arrows marked F - S. The small indicator hand will be pointing to a number on the disk at which the clock was regulated before leaving the factory. Should you find it necessary to regulate the clock, observe the number to which the indicator hand points. The distance between each number is equivalent to 1/2 minute in 24 hours + or -.
FRROM MY PERSONAL SHOP NOTES:
If your clock loses two minutes per day [24 hours] and the indicator hand points to number 8 on the disk - move the disk in the direction of the arrow marked F until the indicator hand will point to number 1.
NOTE:
Before attempting adjustments to the regulator disk, first lock the pendulums by using the lever located on the front of the base. By so doing, you will avoid damage to the delicate suspension wire while turning the regulating disk.
Keep A Regulation Record:
Keeping a short Record of regulation and maintenance on your clock will make it much easier for you to keep it well with in its optimum time-keeping ability. We have found that using the guideline below helps.
Date: +/- in min: How much adjust in Degrees +/-: Personal Notes:
We recommend logging only the times the clock was wound, and any time the clock is regulated or reset.
Times of regulation will include any time the clock has exceeded a 3 to 5 minute error.
Use only ONE form of time references for this, a QUARTZ clock that is known for keeping good time is recommended.
Over time you may find the clock needs only slight regulation; for example, if it has run for approximately 3 weeks and the error rate is under 3 minutes adjust regulator only slightly or simply RE-set.
TEMPERATURE and SEASONAL CHANGES
Temperature fluctuation can affect the time-keeping abilities of your clock.
Never allow direct sun light to come in contact with your clock. This will over heat the clock and it will not only affect the time-keeping qualities, but also dry out the oil and cause premature servicing requirements.
SPECIAL NOTES: REGULATION TENDENCIES
It is very difficult to look at the hands of an analog clock and still determine if the clock is running correctly, therefore I recommend allowing the time error rate on the clock to remain UN-touched until the error rate has exceeded + or - 3 to 5 minutes. This is because 1 minute is very difficult to observe and calculate effectively.
One little known fact about the Rotating Regulator: After the clock is restarted it can take up to 3 or 4 hours for the pendulum to settle down into regular beat rate. Example: If the pendulum is under rotated the clock will run fast and will take some time to bring it up to speed. If over rotated it will run slow. RECOMMENDATIONS ARE: Look at the actual clock time and reset it as closely as possible to real time after the clock has run for about 3 to 4 hours but don't disturb the pendulum. ONLY RESET THE CLOCK IF the actual clock time is off by 1 or 3 minutes.
If you must reset the clock every 3 to 4 weeks, and it is FOR EXAMPLE always slow, Slightly RE-Regulate the clock to compensate for this rate of error. Simply reset the clock several times just to make sure that no mistakes are made.
How to Calculate the Adjustment:
Calculating how much to turn the regulating nut on the rotating pendulum by using the following calculations.

I purchased a Howard Miller grandfather clock and the clock is keeping time but pendulum is barely moving. What's the problem?


Hi Pam,
I have a Howard Miller Grandfather clock and the pendulum swings very slowly and from far left to far right travels only about three inches at best. It doesn't need to move any more than that to make the "Verge" move the "Escape Wheel" to rotate the gears to keep the hands moving at the correct tick.

Re: Galleria / Metro Grandfather Clocck. W/ pendulum on lower hanger clock runs slow. W/ pendulum on upper hanger clock runs fast. How can I adjust so it will keep correct time, or should I take it to a...


Most grandfather/grandmother clocks have an adjustable screw on the weight to slightly extend it or shorten it to satisfy the equation of pendulum swing. the shorter the swing (arc distance) the faster the clock, the longer the swing the longer the time. Check to see if you can adjust the weight up or down on the hanger.

Coaster model 900723 grandfather clock doesn't keep time


Everybody should know that the coaster clocks discussed here run on batteries. The timing mechanisms, the chimes as well as the pendulum all are powered by a battery. Changing the speed of the pendulum is impossible because there is no adjustment. Besides, it wouldn't matter anyway. The pendulum has now affect on the clock's ability to keep accurate time. It is purely aesthetic. This is a pretty cool looking clock and even has weights, but those are also purely aesthetic and do not move the way a classic grandfather clock weight would move. The moments with these clocks are not designed to be worked on. These clocks are relatively inexpensive (approximately $300) but do add a nice look to your home. Grandfather clocks snobs would say though; this is not a true timepiece. They're right... Sorry._1513.jpg

My wall clock runs about 10 min utes fast per 24 hours. I has a pendulum with an ajustable screw at the bottom. Can I turn this screw to adjust the running time. If so, which way (shorten or lengthen)?


You have to lengthen pendulum as this will make watch tick slower. Can not say for how much as for every particular clock there are different adjustments.
Do it bit-by-bit unscrewing the screw thus lowering the bob. Observe time keeping day-by-day and eventually you will reach the right length of the pendulum for precise timekeeping.

Rate me, please.

What ports wind what?


On mine, the center one (@the 6 position) is the one that keeps the pendulum swinging. It is the one that lengthens the most during the week and if I forget to wind it, that pendulum is all the way down when the clock stops.

I inherited a grandfather clock which runs slow


You have to adjust the bob on pendulum. If the clock is slow, the bob on the rod must be pushed up. If the clock is fast, the bob must be pushed down. Do adjustments bit by bit, day by day till the clock is keeping time. If all this does not work, you may need to replace suspension spring (if there is any). If there are no suspension spring, the clock may need proffessional attention.
