The clapper on an English handbell is on a hinge and moves back and forth in a single direction, unlike a school bell in which the clapper swings freely in any direction. It also has a spring that holds the clapper away from the casting after the strike to allow the bell to ring freely.
In this case, the bell will catch up with the clapper and if rung to or near full circle will carry the clapper up on the bell's trailing side. Alternatively, the clapper may have a shorter period and catch up with the bell's leading side, travel up with the bell, and come to rest on the downhill side.

The thickest part of the mouth of bell is called the soundbow and it is against this that the ball strikes. Beyond the ball is a flight, which controls the speed of the clapper. In very small bells this can be nearly as long as the rest of the clapper. Below the bell chamber there may be one or more sound chambers, (one of which is likely to ...
The bell is suspended from a headstock which can swing on bearings. A rope is tied to a wheel or lever on the headstock, and hangs down to the bell ringer. To ring the bell, the ringer pulls on the rope, swinging the bell. The motion causes the clapper to strike the inside of the bell rim as it swings, thereby sounding the bell.
The magnetic field of the electromagnet collapses, and the clapper springs away from the bell. This closes the contacts again, allowing the current to flow to the electromagnet again, so the magnet pulls the clapper over to strike the bell again. This cycle repeats rapidly, many times per second, resulting in a continuous ringing.
The thickness of a church bell at its thickest part (the "sound bow") is usually one thirteenth its diameter. [11] If the bell is mounted as cast, without any tuning, it is called a "maiden bell". Russian bells are treated in this way and cast for a certain tone. [11] Cutaway drawing of a bell, showing the clapper and interior.
A crotalus on display. A crotalus (Spanish: matraca), [1] [2] also known as a crotalum or clapper, is a wooden liturgical rattle or clapper that replaces altar bells during the celebration of the Tridentine Paschal Triduum at the end of Lent in the Catholic Church.
