The clocks have been around for a long time, since men of antiquity began to seek ways to measure time. Sundials are considered the first and the oldest of them is estimated to come from Egypt over 4,000 years ago. Those and other primitive devices to measure time paved the way for modern clocks today. Currently there are many types of clocks, with different methods of measuring and expressing the time.
We initiated a series of items to meet different types of clocks in the world. A great way to enter the world of collecting clocks.
Operation of modern clocks
Before modern mechanical clocks, people used whatever was around to mark the passage of time. They made use of the sun, moon, and stars. They also used candles, water clocks and hourglasses known. Later, there were astronomical clocks for kitchen, clocks and clocks driven by springs that worked by weight. However, these methods were not only inaccurate, but often difficult to use . Many of them do not even tell the time, but rather mark the passage of time, usually with bells. The problem is that only old clocks are based on continuous processes (such as the movement of the sun). It was not until they began to use oscillatory processes in clocks (like the movement of a pendulum or vibration), it was possible for them to gain precision.
Modern clocks work largely similarly. They need three basic parts: power source, one timebase and display.
A power source, as its name suggests, allows the watch to keep moving, whether it is a spring in mechanical clocks or battery in electronic clocks. A time base is also known as an oscillator. Timebase needs to move continuously at a steady rate. This maintains the accuracy of the clock, ensuring that measures the seconds, minutes and hours in the same way all the time. A quartz crystal and a pendulum are common examples of timebase. Finally, the watch needs a screen by which the reader can interpret the time.
The timestamp is a complex subject and its study has its own name. The horology is the science of measuring time and the instruments used to indicate (clocks, stopclocks, timers, etc.) are only one part of this whole body of knowledge. The clocks are classified in different ways, but commonly are classified according your screen or its mechanism.
Types of clocks by screen
Analog: Perhaps the clock type with which most people are familiar with analog clocks. These use a dial with numbers and hands to tell the time. The hands move around the dial indicating the hours and minutes. In addition to the popular 12 – hour format, analog clocks can have the 24 – hour format, which is used to give the military time.
Digital: Digital clocks are also popular today. They use two sets of numbers separated by colons to indicate the hour and minutes. Time is projected using display technologies such as LCD or LED. The first digital clocks had small hard plastic cards passed to the next number in so far as time passed. Most digital clocks are set to the 12 hours, but some come in 24 – hour format.
Braille clocks: Braille clocks are specifically used by blind people. These show the time by several points highlighted on the dial.
Clocks Speakers: The speakers clocks can also be used by people with low vision, but are more frequently used in telecommunications and in public spaces (such as airports and train stations). These clocks are also popular entertainment purposes. For example, there are several novel clocks having the form of characters films or TV programs.
Types of clocks by shape
Standing clocks: These clocks are popularly known as grandfather clocks, grandmother or granddaughter. These clocks are based on the use of a pendulum or chains and three weights. Dan hour jingling chimes, bells or playing some melody. The most valuable antique clocks standing are those that were made by William Dutton, John Knibb, Thomas Mudge, and Thomas Thompion.
As the name suggests, mat clocks were designed to place them on the table above the fireplace. In the USA. They are also known as clocks shelves. These springs have mechanisms, though some variants have four areas rotate around the column, protected under a glass dome. An interesting fact to note is that, to the extent that the mats were losing importance in homes, they became smaller, in the same way that clocks mat.
They were popular in the 1700s and were made in England. However, they became fashionable in France and Germany and were produced in large quantities in these countries. To the extent that increased the amount produced, their quality was degraded, hence today the most sought are those made in the early years and produced in small quantities.
Cuckoo clocks use weights and pendulums to measure time, but perhaps what makes them unique is the way to give time chiming. Every hour (or every half hour in some clocks), a small door opens on the clock face and a bird appears. Normally when that little bird sings (five “cuckoos” for five o’clock) or may sound a melody. The first cuckoo clock was made in Germany in 1630, in the region of the Black Forest. These clocks became fashionable, and many were decorated with different materials and more intricate designs. Even today are in great demand and cuckoo clocks German mark they can have a high price.
The lantern clocks owe their name to the way they are (similar to the lanterns of 1600), and because they are hung on the wall like a lantern. The first clocks bluff still used weights and balance wheels and only had one hand to give time because they were not very accurate. Later, these clocks adopted the more accurate weights and pendulum mechanism, but eventually became obsolete and were replaced by other types of clocks.
In short, the second part of the article where we will continue reviewing more types of clocks. Do not miss it.
