Adjusting the Tone
The clear, resonant sound of a Chelsea Clock
chime occurs every time the strike hammer
drops onto its coiled steel gong. To strike prop-
erly, the clock must be in an upright position.
If, at any point, the strike sounds “flat” or fails to sound, the
hammer’s head may have become misaligned. You may
adjust it as follows, but first wait until it strikes the next full
hour:
• Access the strike mechanism by removing the back cover
(unscrew the three screws)
If the hammer is resting on, or is too close to, the gong, it
needs to be gently bent upwards – just enough so it’s not
touching the coil while at rest:
• Hold the wire between two fingers while in the rest posi
-
tion (do not press down on it)
• Carefully bend the hammer slightly up and away from the
gong using needle-nose pliers or rigid object
• Using your finger, gently lift and drop the hammer wire to
hear its sound
• Repeat if necessary until the sound is clear and mellow
Note:
This operation should only be performed on the hour
position, never on the half-hour.
Warning:
If striking does not occur at the hour and half-hour
dial markings, the clock must be retuned to Chelsea Clock
for service.
