My Welby mantle chime clock loses time, how do I increase the time speed?

To set the time on a Sterling and Noble chiming clock, please follow these steps:

Remove the clock from the wall or mantle and place it on a flat surface.
Locate the clock's time adjustment knob. This is usually located on the back of the clock and may be labeled "Time," "Adjust," or "Set."
Turn the knob clockwise or counterclockwise to set the correct time. Be sure to move the hands of the clock in the direction of the correct time.
If your clock has a chime feature, locate the chime adjustment knob. This may also be located on the back of the clock and may be labeled "Chime," "Strike," or "Silent."
Turn the chime adjustment knob to the "Silent" position if you do not want the clock to chime. If you want the clock to chime, turn the knob to the desired chime setting.
Once you have set the time and chime settings, replace the clock on the wall or mantle.
Note: It is important to set the time accurately and synchronize it with an accurate time source, such as an atomic clock, to ensure that the clock keeps accurate time. Additionally, it is recommended to consult the clock's user manual for specific instructions and troubleshooting tips.

They should chime on the quarter hours, but it should be a short chime. Some help in the link, but it probably needs servicing.

when it chimes, spin the hands in clockwise direction to match what chimed.

Mine keeps time but no chime. The repair shop says mine is wore out and needs the chimer section replaced. Do not try to repair yourself as it will cost you more in the long run.

Have you ensured that the strike train is wound?

I am hoping that you oiled it also? One trick I have found is to gently lift the hammers and release, sometimes the hammers will release and strike the chimes/gong. Do this 4-5 times and hopefully it will get it chiming for you again.

The next time it chimes multiple times turn the hour hand clockwise until it is pointing at the number of times it gonged. Next take off the dial nut off (make sure to put it in a plastic bag because they can be hard to replace) and turn the minute hand until it chimes signaling 15 minutes after. Now put the minute hand back on pointing to 3 o'clock and replace your dial nut and you are all set.
