Example text

When in motion, the forces due to movement, (dynamic loading) are outwards, so that the direction relative to the frame varies as the bell turns. In other words, the direction of the dynamic forces rotates with the bell, whilst the static forces are always downwards. The combination of these two forces acts upon the frame when the bells are being rung. At the top of the swing the dynamic loading falls to zero as the bell comes to rest, then rises to a maximum as it swings down to the lowest point in its travel.

In some cases, the problem of transport can be tricky. A smaller bell can be carried in the back of a van or lorry; but the very large ones require special flat loaders, and in some cases police escort through difficult places. In ancient times the bells were cast close to the tower, and were then swung over to the tower itself with tripods, or sheerlegs, with rope and tackle. For sheer legs, a couple of stout poles sufficed, lashed together at the top, with their bases connected by a rope to stop spreading.

Since tower bells in England are rung in certain patterns, all the bells in one set are required to have the same natural frequency of swing. Accordingly, a ring of bells is arranged to comply with this by suitably designing the headstock. When you look at a bell in a church tower, you will see that the piece of wood is cut away in the centre to accommodate the crown of the bell. By so shaping it, the time of swing is shortened. Usually the time is about two seconds. The headstocks of the different bells are shaped differently, for this reason, and the bell itself is strapped to the headstock with metal bands.
