Inside the top of our grandfather clock, behind the face, is the movement, or the clock works. It is called the movement because it transfers the motion from the swing of the pendulum through the gears to the hands on the face of the clock. At the bottom of the pendulum is a screw for raising or lowering the disk, which makes the swing shorter or longer so the clock can be adjusted to keep time accurately. This grandfather clock doesn’t sound a deep bass “gong” as one might expect from a clock this size. Instead, the small bell visible at the top of the works gives out a soprano “ding” when struck by the clapper.
