does anybody know how church bells work?

Question

I want to know how the weight of the bell is moved by pulling on ropes?, what is the engineering/mechanical process? - from the pulling of the rope through to the movement of the bell?

A web reference showing illustration would be appreciated.

Answer 1

At the top of the bell there is an "axis of rotation" (an axel, a shaft).
To the shaft is mounted a groved wheel.
To the wheel is attached a rope that goes down.
The "bell ringer" pulls the rope, initiating a rotation of the bell.
He then releases the rope, and the bell starts rotating back.
Like a swing, the bell ringer synbchronises his move with the bell, giving it a little more "pull" every time.
The hammer, by inertia, stays vertical. When the bell reaches enough swing, the hammer hits the bell and the shell of the bell start vibrating...
As long as the bell ringer keeps his movement synchronous with the bell....
"Bangoing... Bangoing..."!

Answer 2

That would be the ones that people ring?, well we will get to the other type later...

The ones that people ring by pulling ropes are left resting hanging down. But the pivot is not at the top of the bell, they are mounted on 2 half axles (one with a wheel with the rope attached) so that the centre of gravity is not far off the pivot.
So, how to ring a bell?, well there is still quite a bit of pull required (more than one person weighs), the bells are "rung up" exactly the same way you get a swing to go higher, each swing, you pull a bit more. When the bell is swinging enough to go over the top it meets a stop (just past upside down), you can let the bell rest there untill you want it to chime, a gentle pull will set it swinging. It will ring, go up the other side of its arc and rest against another stop.

The other type as used in clocks, the bell stays still and the clapper strikes the bell, still heavy, but pounds weight, not tons

Answer 3

The bell has a hammer hanging inside. When the hammer strikes the rim of the bell then the note of the bell sounds. In order to make the hammer hit the bell, then the bell is rocked to and fro. This is achieved by hanging the bell on an axle. Above the axle is a pulley A rope is attached to the bell, fed over the pulley, and hangs down to the ground below. Pulling on the rope starts the bell swinging, and pulling hard enough swings the bell enough to make the hammer strike. This is call tolling the bells

Answer 4

It works same as a pendulum. You have to tug on the rope then let go, it swings back, tug agian, it slowly builds momentum until it strikes the ringer. The pivot point is located so that it has some counterweight, i.e., able to be moved without motorized aid.
