You may have noticed that the tower clock isn’t going. This isn’t because of laziness on the part of those who wind it, but is because the pendulum has dropped off. In the picture you can see that the piece of spring metal which supports the pendulum and allows it to swing has sheared off where it connects to the clock’s frame. This is normal wear and tear: the spring is reckoned to last 50 years or so.
The good news is that the remains are now in the hands of Smith of Derby who maintain the clock. They will produce a replacement and return to fit it. At the same time they will also replace a worn brass cam follower that controls the chimes every quarter or an hour: these have been rather erratic recently.
