Grandfather Clock Chimes Forever Correction
When the clock misses the stopping point sometimes and chimes more than one quarter at a time, or just chimes forever, this is the correction.
There is a cam with graduated humps on the top right of the front plate of the Movement. There are 4 lower portions with a small hump and the next one is bigger and then so on. The smallest hump is the 15 minute mark where the hammers strike each one time each right down in a row. So this round brass piece with the humps on it, controls when the movement is to stop chiming. The small hump represents the first quarter as this is the shortest chime of them all. The hourly chime is in turn represented by the longest hump as it is the longest song of the four quarters. This same largest hump has an even higher hump at the end of it, this will drop the saw tooth rack to fall so when it’s done chiming the top of the hour, it can start striking out the hours with help of the saw tooth rack counting system.
If the clock is chiming forever it is these two areas where the arrows are pointing. If the left hand cam is in the deep slot at the same time as the right hand cam is in the deep hump, it will not chime forever. Please note if turning the left cam to be in the lowest hump independently of the gear train (by holding the gear train still with fingers) it will be require resetting the chime song.
