I have a Howard Miller dual chime grandfather wall clock model 620-184 and I don't know how to get it to chime hourly it is chiming every quarter hour how do I get it to chime hourly ?

If only on the ¼ hour, but not on the others, there's a worn or chipped geartooth. If All of the chimes are 5 minutes off, you can usually adjust the position of the minute hand to correct it. You may have bent, or wore the 'd' shaped hole in the minute hand by aggressively turning it to set the time.

If you need to ask how to fix it, it probably means you shouldn't be tinkering with it.

You have something that represents a fair chunk of money and it would be wise to consult an experienced horologist about your problem or perhaps consult the manufacturer.

The cure might be as simple as removing the hands and putting them back to coincide with the chimes but it is presumably a fault that developed over time. I doubt the hands moved their relative positions by themselves but rather something inside happened.

Owning a mechanical pendulum clock is a hobby that requires some basic knowledge about how it works and how to care for it. The hands should never be turned backwards, for instance. Changing the time for daylight saving means either stopping the pendulum for an hour or advancing it by an hour and pausing at each quarter to allow the chimes to sound fully. Any mistakes will mean winding on many hours or stopping the clock and waiting.

OK, google is your friend, but before I go there, recognize that pendulum clocks are generally regulated by the speed/period of the pendulum. A shorter pendulum has a shorter period/faster time and vice versa. So in general, look for the length adjustment of the pendulum weight.
Specifically, here is a link to a google-d search:

Hello Shirley Haas,

Leave the weight fully extended (stop the clock)
and start checking your local area for clock-smith
that make house calls (run on hour strikes are much more common... but whatever you say... "CHIMES" the cause
is likely the same: Little or no maintenance).

These clocks need to be lubed and serviced and it is work
best left to the serious professionals.

You can probably get away with another 35 years...

Remember we have time on our side...

As for me...
I bought a junk clock to EXAMINE & fix (did)
I purchased synthetic clock oil (LIBERTY noted below)
and lubed ALL the obvious spots...
wiping excess away with Q-Tips.

Then I assaulted my own RIDGEWAY...
Got it running & regulated (was NOT my problem)...
My pendulum only needed to be centered correctly
(oh well).

I could NOT pull up YOUR 610-808 movement... but on the movements I have done you can see the hour strikes & the lever that triggers that motion (HOURS are each a spike on
the gear wheel... from one (^), 2 (^^) to 12 (^^^^^^^^^^^^)
progressively (pretty obvious if you are looking).

Go there... look... lube..!! Be gentle... VERY GENTLE...
or better ... call in a QUALIFIED SERVICE PERSON.

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.

Fix Clock That Gongs Wrong

In a quartz movement clock, with a problem like this, the chime box (or whole movement) will need to be replaced. Timesavers.con carries a large selection of chiming quarts movements.

We understand your question:

The hand has a center bushing with the square hole in it.Remove the hand and use a pair of pliers on the bushing in the minute hand then re-clock or rotate the bushing back on the quarter hour then replaced it back on the clock.

Hope this tip provides some workable ideas for this repair.

Howard Miller offers this feature: This is how it works.

Automatic Night-Time Silencing Option
Grandfather Clocks will offer a night time shutoff option. There are 3 options on this lever.
1) "Night On" - This will keep the chime striking 24 hours
2) "Night Off" - This position will turn off the chiming between 10:15PM and 7:00AM
3) "Strike" - This position will allow the movement to strike the hour without the Westminster melody if the other Westminster melody lever is turned to Silent.

Hope this helps.

If you manually set the time, the chimes will be off unless you wait for the chiming to finish before continuing to turn the hands.

Press the TEST button to get the correct number of chimes in synch with the actual time.
