Of all the inventions that helped to improve the precision of mechanical clocks, no one was more important than the speed regulator. In this paper, the history of the development and evolution of the speed regulating mechanism of cheap nixon watches from early prototype to the latest material is the first part: from the water clock to the Verge Escapement.

The clock mechanism of the Renaissance.
Man’s perception of time comes from celestial bodies. Day after day is night, and after night is day, constant and regular. Other predic Cheap Nixon Watches events are for early humans, especially for women, who are responsible for family meals and remember the reproductive cycle. Man divides time into shorter intervals according to the phases of the moon. At the end of the year, 365 and a quarter of a year is divided into four seasons, divided into four seasons, which correspond to the earth’s orbit around the sun. In this way, man has mastered the first “governing body” (calendar) in history.
The next step is to devise methods for measuring shorter intervals. Prior to the invention of mechanical clocks, the sun’s apparent motion on the horizon, and the projection of the object, played an important role in the measurement of time. But if the cloud is obscured and the sundial cannot be projected, the mechanism loses its potency. The sundial measure depends on the day, intermittent failure, the solution is the water clock. The water clock is driven by water, not a simple, nearly toy device. Arab scholars leave records told us that, in the west than uz Greek inventor) of a water clock appears to have been assembled, tiki she pull mechanism, can be complicated gear train, predicted astronomical phenomenon.

From running water to oscillating.
When a drop of water falls into the water, it creates a ripple, which is then spread across the water according to regular rhythms, a movement that mathematicians can convert into equations. We tend to forget is that early water clock is not simply be a container of water poured into another container, floating pointer and gear means that they will be divided into time intervals can be measured. As Gerhard Dohrn – van Rossum in his “History of the Hour: Clocks and Modern Temporal Orders” (published by the university of Chicago press, the author points out, the earliest Modern clock with automatic control mechanism, and cistercian has wonderful roots.
It is generally believed that the mechanism (regulator) to prevent the rotation of the wheel system in the time of the time of beating is to be used to control the rotation of the gears in a certain period of time by using similar principles. In the middle ages, these mechanisms are complex part of the water clock, which must include a similar early original balanced set of institutions, on the other side of the bearing the weight of far from or close to the axis of rotation, to produce a slower or faster oscillations. That’s a reasonable assumption. Perhaps the monks wanted to replace the frozen water clock in the winter, so they dropped the liquid “engine” and turned to mechanical devices. Under the action of the wheel system, gravity becomes a controlled rotary motion, which is then translated into translational motion, and the driving hammer strikes the spring and makes a sound. Don’t forget, in the 12th and 13th centuries, time is “listening”, not “watching”.
“Onion”, inscribed “Ladouceur, Faubourg saint-antonie, Paris”, about 1690.
With the advent of the earliest adjusters, the tabulation made a great leap. Although it appears rough (except John harrison H4 Marine chronometer regulator assembly), but this kind of crankshaft tackled longitudinal institutional applications has a long history and it is assembled into each of the 13th century to the early 18th century chronometric instruments, bell desk clock, long shell, or the first Cheap Nixon Watches. The mechanism gives the clock a steady rhythm by suspending the gears (otherwise the gears rotate at an uncontrollable rate.
This clever regulator, designed to be used to assemble clockwork (helical spring) driven clocks or Cheap Nixon Watches, has promoted the emergence of two new inventions that balance the power of the clockwork. The first is the uniform force wheel, which is used mainly in the german-speaking countries of 1600 years ago to exert the opposite force of friction on the wound. The second is the equal-force cone, which is a conical structure that is gradually shortened by a spiral coil, and is connected to the wound by a slender chain, a cable, and even a gut (also used as a string instrument). The tension of the wound will be gradually reduced at any time, and the attachment will then move from the narrower end of the cone to the wider end to form an effective compensation. Thus, no matter how the tension changes, the force of the transmission to the gear system remains constant (like the wheel of a bicycle rear wheel).
The manufacture of the device is complex, but it exists to make the wound torque in the upper chord, ensuring that the clock is functioning properly when it is on the string. Without it, the function of the machine shaft escapement will be greatly reduced because the oscillation will be fully controlled by the power provided by the spring. Clockwork, sesame chain and crankshaft escapement (escapement wheel is perpendicular to the gear train, the two “escapement”, in turn, and the escape wheel convex tooth bite) combination, almost before the 1650 s the only use of escapement. It is important to note that the original balance with two “pendulum bars” was replaced by a ring wheel in the 16th century. The ring wheel is affected by different positions, but is also sensitive to impact. If there is no spiral, the accuracy is still insufficient.
