The Atmos Clock - Perpetual Motion?

The Atmos Clock called, erroneously, the perpetual appeal clock, first saw the light of day in the early seventeenth century.

It's close to perpetual motion, but no cigar! It violates the Second Law of Thermodynamics, as well as the law of conservation of energy, since it fails to yield vigor from nothing. Not only that, but these clocks do want servicing, usually every 10 to 20 years. Perpetual appeal would mean the negation of conflict and any other element that might stop the clock, meaning that there would never be the need for assistance of any kind.

There is an vigor source, ethyl chloride gas, stored in the shape of a very superior hollow spring, set in a large drum at the back of the clock. Just one degree of climatic characteristic convert has the ensue of holding the clock running for two days. A plate outside this spring acts on another, much weaker spring, which in turn is linked to a chain attached to the mainspring. In this way the clock is kept wound. So whether the climatic characteristic rises or falls, the incompatibility will always wind the clock.

Cornelius Drebbel made such a timepiece for James the First of England, and also one for Rudolf the Second of Bohemia. These clocks relied on atmospheric pressure and climatic characteristic changes to keep them wound.

The Enlightenment saw an experimental clock made in 1760 by James Cox and Joseph Martin. This clock relied naturally on atmospheric pressure.

It wasn't until 1928 that the first Atmos appeared as we know it today. Invented by a gentleman named Jean-Louis Reutter, it carries the unofficial name of Atmos 0. This was followed by the Compagnie Generale de Radio, a French company, bringing out Atmos 1, using mercury and ammonia bellows to power it. On 27th. July 1935, Jaeger Le Coultre stepped in and industrialized the second design, Atmos 2.

A word about how Jaeger Le Coultre came into being. The firm was originally started in 1833 by Antoine Le Coultre. It took until 1903, however, that the company as we know it today was born. Edmund Jaeger, of Paris, threw down the gauntlet and challenged the French watchmakers to yield pocket watches that were wafer thin. Jacques-David Le Coultre, the grandson of Antoine, took him up and did unquestionably make a superb pocket watch of tiny cross section. So the partnership came into being. Now, they are situated in the Valee de Joux, in the Swiss Jura Mountains.

Reutter spent a long time examining the movement of the 400 day clock, and utilized the torsion pendulum and suspension spring for his Atmos. This spring holds the heavy brass pendulum, considerably heavier than a 400 day, but the operation is very much the same.

The bellows filled with ethyl chloride occasionally need to be replaced. When they come from the material house, they're bound tight with a thin steel strap. To naturally cut this strap and then expect to drop the bellows in place is an rehearsal fraught with despair. The best way of fitting them is to place them in the freezing compartment of your refrigerator so that the bellows contract. The strap will naturally fall off, and you are then able to place the bellows in the drum and replace the back, which is a bayonet fitting.

The movement itself is small, delicate and fully jewelled. I do not propose placing the limited plates in an ultra-sonic cleaner. It's inherent to shatter the jewels in this way. Wash the plates by hand in a good cleaning explication and 'peg them out'- run pith wood straight through the holes until they're clean. The pallet jewels should be examined and scraped clean, again with wooden slips. Never apply oil. The power is so delicate that oil will have a retarding effect

There's no question that the Atmos is a superior clock - but not quite perpetual motion
