Hi - apologies I'm sure I should and will read a bazillion articles. But it's hard to come from zero, I don't know exactly where to start or whether my problem is a no-brainer or super-complex. I don't even have the language. Ordinarily it's polite to read more before posting but I have little time. I'm visiting my mom with a Colonial Mfg Company (Zeeland, MI) g-father clock that has stopped working. I think I have some ideas of what is wrong, no real idea how to fix it and no idea if I'm really messing it up. I apologize enormously in advance if any of the above is offensive. I really appreciate suggestions anyone might have. The clock was moved, and survived the move for a few months then stopped. Now what seems to be going on is the - again, apologies because I know the name of none of these parts - there is a seconds arm and a separate clock face for that small hand. It goes to a rocking "v" shaped - what would it be called, a device that halts the movement of a gear - right, left, right left, it allows the gear to click around one bit at a time. Is this a cam?? And this V-cam or whatever, is attached to a lever that that fits over a post that attached to the pendulum. So when the pendulum goes back and forth it moves this lever which clicks this cam in and out of the gear that controls the seconds hand and should result in the seconds-arm going around. It will for a while, then the cam sticks a little, the lever arm doesn't rock as it should and the pendulum goes to the side; it's inhibited from its full straight arc. The whole thing stops then, it just slows down. And of course the seconds hand doesn't progress because that gear doesn't click through. It *can*, it just doesn't. And here's perhaps a real no-no, but I can get it to proceed correctly by (a) manually moving that lever attached to the cam myself - when I do this gently I don't feel anything that prevents the gears from fully moving and halting the process. Alternatively (b) I can apply a teeny bit of pressure to the seconds-hand when it gets stuck and this seems to be enough to cause the gear to move just enough to not get hung up and keep going. So I don't know what's *causing* that gear to hang up - if either the cam or the gear were inhibited, that would do it. A question: is there a spring that keeps the gear going around? Could that be insufficiently wound? Another probably no-no I did. In fiddling with the seconds hand, I wondered whether that just wasn't pushed in enough, or somehow its shaft was slipping. The hand can be gently moved in and out from the front of the clock face. I didn't try to remove it altogether. I was wondering whether there was a spring in there someplace? I observed no difference whether that seconds arm is pushed all the way in or pulled a bit out. Slight pressure on the arm to get it to keep the gear moving seems to work. And I was worried the arm was somehow getting stopped by the clock face, that's why I pulled it out a bit. But seemingly it doesn't affect anything to move the seconds hand in or out a tiny bit. Here's another probably bad thing I did. I was able - working on the theory there was a spring back there that needed tightening - I was able to get the gear to skip a couple cam teeths, if you follow. And indeed that does change the lever arm. It seems to be tightenable this way because the lever arm "skews" more leftward than right. So much so that the bit that fits into the pendulum no longer does. There's an adjustable wheel on the pendulum where the two articulate; even on its furthest bit it won't go. So that was obviously wrong but interesting -- I'm sure that lever should be approximately straight up/down. So I did get to put it back. But then it seems to have not enough "umph" to keep going around. So .... I don't know if what I've learned is symptomatic or a problem. Is there anyone willing to help me with ideas of something to try? Thank you very much!!! Again, apologies for asking this prior to reading and knowing more. I'm just pressed for time... many thanks!
