For the ringers maybe, but what about the bell?"

It only drops the clapper from halfway across the mouth and then the centre
of gravity of the clapper can only be dropping by a few centimetres.
Compare the potential energy PE = mgh to the kinetic energy of the clapper
swinging into the bell when it is ringing KE=mv^2 and I think you will have
your answer.
