The three weights provide power to the hour strike (left weight), time (center weight), and chime melody (right weight). Without these weights, the Grandfather Clock would not operate. Each weight is different and must be properly hung from the movement (left, center, right) to ensure proper operation.
What are clock weights called?
Pendulum or Weights
Pendulums are the oscillating objects seen in long-case clocks and are most prominent feature associated with antique clocks. A pendulum or weight is suspended from a pivot so that they oscillate. The time taken by a pendulum to swing from left to right is essential in calculating time.
What are the parts called on a grandfather clock?
The escapement consists of several pieces that work together: the pendulum, a toothed gear and a piece called the anchor that engages the gear’s teeth. At each swing of the pendulum, one gear tooth is allowed to escape.
What do the two weights in a grandfather clock do?
Understanding Grandfather Clock Weights
The left weight powers the hour and the number of chimes to coordinate with the hour. The middle weight powers the pendulum, and the right weight powers the melody you hear.
Do grandfather clock weights weigh the same?
Purpose of the Weights: Most modern grandfather clocks will use three weights where each of the three have their own function. The weights are filled with cast iron within a brass casing and are quite heavy. Each weighs differently for the job at task.
What are the 3 weights for on a grandfather clock?
The three weights provide power to the hour strike (left weight), time (center weight), and chime melody (right weight).
How do you put weights on a grandfather clock?
Grandfather clocks are weight driven. Pick up the weights one at a time and turn them upside down. Look for the letters “L,” “R,” or “C.” Arrange them left to right on the floor in front of the clock with “L” being the left hand weight, “C” being the center weight and “R” being the right hand weight.
How do you manually lower weights on a grandfather clock?
Using cloth gloves, or at least a cloth of some kind, pull down on the weight some. This is the same as making the weight weigh more. At the same time, turn the minute hand past the quarter hour to see if it will engage the chime. When you advance the time and make it chime, the weight will slowly come down.
What are the parts of a clock called?
Case: The body that houses the components of a clock. Minute Hand: The longer hand that indicates minutes. Hour Hand: The shorter hand that points to the hour. Barrel: The cylindrical metal box that powers the mechanical timepiece with a mainspring and a toothed round gear.
What is the swinging part of a clock called?
A pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. The advantage of a pendulum for timekeeping is that it is a harmonic oscillator: It swings back and forth in a precise time interval dependent on its length, and resists swinging at other rates.
How much should grandfather clock weights weigh?
Most grandfather clocks weigh somewhere between 100 and 220 pounds, depending on the size. So, we suggest that you measure the dimensions of your clock and research the exact model on the Internet to find an approximate weight. Chances are, it’s around 100-150 pounds.
How heavy are the weights in a grandfather clock?
Grandfather Clocks weigh anywhere from 100 to 200 pounds and require special attention when moving them from one place to another.
How heavy should grandfather clock weights be?
In general, 9 pounds is far too heavy for a clock like the abovementioned Kieninger, especially for a Graham escapement. The same clock would run well with 5 to 6 pounds. Hermle recommends 4.5 pounds for their grandmother movements (451), and I have seen many equipped with 6 pounds.
