How does a torsion clock work? A torsionpendulum clock, more commonly known as an anniversary clockor 400-day clock, is a mechanical clockwhich keeps time with a mechanism called a torsionpendulum. The clock'sgears apply a pulse of torque to the top of the torsionspring with each rotation to keep the wheel going.

How does a torsion spring work on a clock?
The clock's gears apply a pulse of torque to the top of the torsion spring with each rotation to keep the wheel going. The wheel and torsion spring function similarly to a watch's balance wheel and hairspring, as a harmonic oscillator to control the rate of the clock's hands.
How do gears work on a clock?

How often should you wind a torsion clock?
It's best to wind the clock once a month. But some models will run up to 1000 days on a single winding. Torsion clocks are capable of running much longer between windings than clocks with an ordinary pendulum, because the torsion pendulum rotates slowly and takes little energy.
How do you set a torsion clock?
1:532:45And you would grab the pendulum. And move this serrated disc in the direction you to go. ThisMoreAnd you would grab the pendulum. And move this serrated disc in the direction you to go. This direction for speeding the clock up or the other direction to slow down.
How do you start a torsion pendulum clock?
For the type of clock with pendulum locking device at the bottom rear of the movement. To wind this clock, put the key on the square and turn counterclockwise, 1/2 turn at a time. Release the key gently after each half-turn, don't let let it snap back suddenly.
How does a 1000 day clock work?
The Schatz 1000 day clock is based on Schatz's miniature 400 day clock movement. A larger mainspring, with about 2.5 times the amount of energy storage, is used, but the gears (except for the barrel and second wheel) and escapement (except that the anchor has a longer arbor) are the same.
How do you regulate a 400 day clock?

How do you set a mechanical clock?

Do anniversary clocks need batteries?
Today battery operation has replaced physical winding, although the basic mechanical principles remain intact. "Anniversary clocks" still stands, because in most cases, the batteries need replacing about once a year. The original anniversary clocks are now mainly family heirlooms and the domain of collectors.
Who invented the 400 day clock?
The torsion clock, typically known as a 400-day clock in the U.K and the anniversary clock in the United States, was first developed by Aaron D. Crane in 1841 using a rotary—rather than swinging—pendulum invented by Robert Leslie nearly 50 years earlier.
Why is it called an anniversary clock?
The “anniversary clock” is called that because it'll run for about 400 days on one winding, so you can wind the thing on your wedding anniversary, perhaps making a celebration of the ritual.
Why is my wall clock running fast?
To slow down the clock, loosen the adjustment nut (turn it toward your left). The bob will settle lower, making the effective length of the pendulum longer. The clock will run slower. To speed up the clock, tighten the nut (turn it toward your right).
Why does my 400 day clock stop?
Its purpose is to suspend the balls in the air and allow them to slowly rotate back and forth. If this gets bent AT ALL the clock will not work. The only bending this spring can do is twist back and forth with the balls as they rotate. The spring being bent is the number one cause for most of these clocks not working.
What causes a grandfather clock to run fast?
The longer you make the pendulum, the slower the grandfather clock. The shorter you make the pendulum, the faster the grandfather clock.
Who invented the torsion clock?
Around 1880, a German clock maker, Anton Harder, patented a torsion suspension clock that worked for a year with just one winding. These "anniversary clocks" were also called "400-day clocks" and "1,000-day clocks" to indicate winding frequency.
What is a torsion pendulum?
A torsion pendulum operates the clock. After several incarnations, the flat disc pendulum of the earliest anniversary clocks became today' s torsion suspension pendulum that twirls while suspended in a hovering position. Usually, three to four small gold, silver or crystal globes on individual spokes decorate the base.
How does a pendulum work?
The pendulum is suspended from a torsion spring. The spring is a rope-like suspension wire. The torsion spring works like the high wire supporting a Cirque de Soleil performer, except that it does not have the same flexibility of movement. It moves only clockwise, then counterclockwise, in a fixed rotation.
Why are anniversary clocks still used?
"Anniversary clocks" still stands, because in most cases, the batteries need replacing about once a year.
What caused the suspension spring to become inaccurate?
Temperature and humidity fluctuations affected the elasticity of the suspension spring in early torsion clocks, making them inaccurate timekeepers. In 1951, Charles Terwilliger invented a suspension spring that overcame the problem. Advertisement.
