I have acquired what is apparently a Friedrich Mauthe, Schwenningen clock that hung on a wall in an antique store for over a year. I know that it needs a thorough cleaning but was surprised when I put the pendulum on and it started running. In fact it is keeping very good time for over a week now.
However, I have a couple of questions if some of you experts can help me.....
1. The clock strikes the hour and half/hour. But over the course of a day, it will get out of sync and it might strike once on the hour and the number of hours on the half hour. Also, it will get to a point that it strikes the wrong hour, not just an half hour off but it might strike four times one hour, five the next then eleven or nine or sometimes even fourteen times. I have not disassembled the clock yet but can somebody give me an idea what to look for that would cause that.
2. The other question is simply something I do not know or understand about the pendulum. As you see from the photo, there are two horizontal rods above the bob. The top rod is attached permanently but the bottom one has an adjustment screw. What is that for? There is also a "time adjustment" screw on the bottom of the bob, which I understand the function.
Thanks in advance for your help.....
