SELF ADJUSTING VERGE
The self adjusting verge is used on many of the modern mechanisms.
The idea is that if the tension of the verge clutch is set just tight enough to push
the pendulum ; but loose enough to allow it to split the difference between each
side of the impulse with a specially designed escape wheel that has indentations on
the teeth. After running for ten or fifteen minutes and having the difference split minutely at each tick , the clock will be in beat. Its a good idea and it does work usually.
The most common problem with this kind of verge is stopping. Typically they will not stay in beat if they are too tight, and then they will stop. If they are too loose, they may stay in beat , but will
not run dependably. DO NOT EVER OIL ONE OF THESE SELF-ADJUSTING VERGES. YOU WILL RUIN IT
IF YOU OIL IT. DO NOT EVER PUT ONE OF THESE IN AN ULTRASONIC CLEANER ; THIS WILL DO THE SAME TYPE OF DAMAGE AS OILING THEM.
