Quick Answer: How A Grandfather Clock Works

The core is the escapement, comprising pendulum, anchor & gears. It is attached to gears with special-shaped teeth. Each time the pendulum swings, the anchor releases one ‘tooth’. This tooth nudges the pendulum in the right direction & transfers enough energy to overcome friction & keep the pendulum swinging.

How do pendulum clocks keep going?

As it swings from side to side, it rocks a lever called an escapement that locks and then unlocks the part of the mechanism driven by the falling weight. Since (in theory, at least) a pendulum of a certain length always takes the same amount of time to swing back and forth, the pendulum is what keeps the clock to time.

Why does the pendulum stop swinging on my Grandfather Clock?

The reason a clock pendulum often stops swinging, after being moved, is because the clock case now leans at a slightly different angle then it did at its former location. A clock is “in beat” when the tick and the tock are evenly spaced.

How often do you have to wind up a Grandfather Clock?

Grandfather clocks require winding once a week. Grandfather clocks add a certain warmth to a home that few other pieces can match. Chain-driven grandfather clocks have three chains, with a weight on one end of each chain. Each chain is responsible for a particular function of the clock.

How long does a Grandfather Clock go without winding?

Almost all grandfather clocks are made to run for seven or eight days without winding, so winding them on the same day each week will ensure that it never stops. If your clock stops before its regular winding time, however, you may need to wind it more frequently.

What causes a pendulum to eventually slow down and stop swinging?

A pendulum is an object hung from a fixed point that swings back and forth under the action of gravity. The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) slows it down and eventually stops it.

Can you move the hour hand on a grandfather clock?

Grandfather Clock Repair The HOUR HAND ONLY can be moved forwards or backwards without any problem. If the clock is striking the wrong hour, you can simply rotate the HOUR HAND in either direction to the correct hour the clock is chiming.

Why would a grandfather clock stop working?

Often a pendulum clock will stop when it has been moved, bumped or even a too aggressive push to restart a pendulum. It is not broken, only out of beat. This only takes a few minutes to readjust and all pendulum clock owners should learn how as this will happen eventually.

Why is my grandfather clock not working?

1) Examine the dial on the grandfather clock and check to make sure the hands are not touching or hanging on any parts of the dial or second hand. 2) Check the leveling of the grandfather clock. 4) Listen to the ticking of the grandfather clock to make sure you are hearing a very even “tick-tock”.

What is the crutch on a pendulum clock?

The crutch is the thin brass rod that connects the escapement to the pendulum. It extends from the upper part of the clock movement down along the pendulum suspension rod and loops once around the suspension rod at its bottom point. Bend the crutch rod while supporting it with the other hand.

How do you keep a pendulum swinging?

There are several things that you can do to make a pendulum swing for a long time: Make it heavy (and, specifically, dense). The more mass a pendulum has, the less outside influences such as air resistance will degrade its swing. Put it in a vacuum. Use an escapement mechanism. Give it a large initial swing.

Why is only the middle weight dropping on grandfather clock?

If the clock is running but not chiming, then only the center weight will drop. Typically, what we find is that the grandfather clock has not been serviced and the oil has dried up in the movement and therefore the chiming side of the clock is hung up, or worst, worn out.

How long does a grandfather clock last?

Most quality new grandfather clocks will run about 20+ year if you set one up and never maintain it, but oiling every few years may make the clock last a lifetime (or two).

How much does it cost to service a grandfather clock?

The cost of servicing a grandfather clock can vary between $100 and $2,500, depending on what services are necessary. Normal servicing is not too costly while repairing and replacing parts can quickly add up. Major factors that impact the cost include: The type of clock and internal mechanisms.

Should the weights on a grandfather clock drop evenly?

Yes, the order is critical for proper function. On 99% of floor clocks (grandfather/grandmother) with three weights, the heavier weight goes on the right-hand chain hook or pulley as you are FACING the clock. The two heavier weights go on the center and right hooks or pulleys.

How do you fix a grandfather clock wound to tight?

Strike weight stuck With some cloth gloves on, or at least a cloth of some kind, pull down on the weight some. Again, this is the same as making the weight weigh more. Doing this will make the clock strike. Advance the minute hand and let it chime each quarter until it plays the top of the hour song.

What is the difference between a grandmother and a grandfather clock?

Both grandmother and grandfather clocks are long case pendulum clocks, but grandfather clocks are generally taller than grandmother clocks, measuring in between 6 and 7 feet, while grandmother clocks typically measure between 5 and 6 feet. Grandmother clocks rightfully derived their name from the grandfather moniker.
