Mechanical Chime Sequence ReSetting Instructions

The Westminster mechanical clock does not sound like Westminster when it plays? This would require these Mechanical Chime Sequence Resetting Instructions

There is a cam with humps that graduate 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 so on. The smallest hump is the 15 minute mark where the hammers strike one at a time right down the row. 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 the longest hump as it is the longest song of the four quarters. This same large 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. This is with the help of the saw tooth rack counting system.

Run the chime by turning the hand (mounting with the nut is not necessary, just put it on there so you can turn the hand shaft and make it chime). Notice the cam with the humps spinning and wait until it gets to the end of the smallest hump and stop the gear train from moving with your fingers and hold it. This is the end of the first quarter, the first 15 minute mark. Now set the hammers to match this from the back of the movement.

Please now look at the back of the movement. There is a big gear on the OUTSIDE of the back plate of the movement. It has a set screw but loosening it is usually not necessary. Anyhow, while turning this gear and at the same time not letting the gear train run, it will turn around and move the hammers until the hammers strike each one time right down in a row, representing the end of the first quarter.

Use your left hand and put one finger on the top of the left gear train as to not let it spin. At the same time, use your right hand and turn this gear on the back of the movement until that very last hammer drops down after the 1-2-3-4-5 hammers drop in a row.

With this set to the position where the last hammer drops, tighten that cam (this explanation was in the first paragraph) so the bar that rides the cam is in the down position just after the smallest hump on the cam. Now the chimes are set correctly.

How do I make the chimes louder on my chime clock. I can barely hear them?

I have 1161-053 3 chime movement on my 30 + year Howard Miller Grandfather clock. It chimes with a slightly inaccurate chime and will not stop chiming unless I turn it to the silent position. It’s been like this for at least 20 years. I haven’t bothered to have it repaired or replaced. I’ve talked to a clock repairmen and his comment was due to its age it would be best to replace the movement. The time part of the clock works normally, but it’s been silent for many years. Now I would like to have it working with all three chimes. I would appreciate any suggestions you might have.
