 FACT: Ben climbs up the bell rope and out the top of the bell tower  to escape the chapel. A bell in such a small tower could not  possibly be heavy enough to counterbalance Bens body weight.  Therefore Ben would pull the bell to its limit while climbing, and  the bell would not ring repeatedly as he climbs the rope. And when  Ben pulls the rope taut so that he can rappel down the roof, the  bell rings twice more.
