Unitarian church bells explained

How do the bell chimes work to sound on the hour?  This learning journey started while working with a vendor on security cameras. I was in the bell tower for the first time.  I looked at all the equipment and wanted to learn more.

 

This picture shows a motor coupling between a 220-volt electric motor and a gear drive assembly in the bell tower. It is connected to the equipment used to ring the bells. Notice the pile of brass shavings on the floor and the shredded gray connector belt. I had never seen a coupling like this before, but I knew it was not good. I showed the folks on the Building Committee the photo. They asked if I would help figure out what was going on. So, always curious, I wondered how it all worked, how it kept accurate time (probably not with NTP [Network Time Protocol] from the Internet), and how we’d fix it.
