SEWING MACHINE

Thus, today, we have new and different designs and different colors of clothes available in every market, mall and shopping center all the time, but have we ever thought about how these clothes are made, what is the history of the machines on which they are sewn? Thus, we have been ignoring the history of some machines. 

For example, 

 "We all knows very well about the invention of blub also about their inventor, but we do not know about the invention of the needle?"

Today we have written the history of such an invention.

Millions of years ago,  First priority was to cover the body, When mankind first set foot on earth. Thus, the first clothes were made of animal skins, which not only protected the human body from various insects but also from weather changes. Then, every passing era and century played an important role in innovating this clothing. Thus, different cultures played an important role in the preparation and design of clothing.

We can proudly say that the clothes that you and I wear today are more comfortable and durable than the clothes of the princes and ministers in the past centuries. The main reason for this is the innovation of science and human thinking, which has been keeping the human mind abreast of innovation with each passing time.

Thus, today, we have new and different designs of different colors in every market, mall and shopping center, but have you ever thought about how these clothes are made? What is the history of the machines we sew on? We have been ignoring the history of some machines. For example, we know very well who invented the light bulb, but we don't know who invented the needle.

Today, it would not be wrong for us to say that the clothes we wear today are more comfortable and durable than the clothes of the nobles and nobles of the past centuries. The main reason for this is the advancement of science and human thought, which has been bringing the human mind closer to innovation with each passing time.

Today, we have brought under our consideration one such invention related to human clothing and its innovative thinking, which may have started with the hand, but today it is playing an important role in the most modern clothing in the world. Yes, sir, we are talking about the sewing machine. Today, this machine is present in almost every home in the world with different designs and functions.

In 1755, German-born inventor Charles Friedrich Wiesenthal, living in England, patented a mechanical sewing device based on needle design with two points and an eye for use. 

THOMAS SAINT SEWING MACHINE

Later, In 1790, English cabinet maker Thomas Saint built upon earlier ideas, creates an mechanism aimed to stitch on tough materials like leather and canvas.

The sewing machine developed by Thomas worked using the chain stitch method, in which a one-sided stitch was sewn with the help of only one thread.

Thus, with Charles's invention in the mid-eighteenth century, the process of innovating it began.

Which continued until the early years of the nineteenth century, in which several important inventors, Thomas Stone, Thomas Anderson, John Duncan and Josef Madersperger, are of particular importance.

In 1829, French tailor Barthelemy Thimonnier introduced a practical sewing machine that become famous due to the widely producing uniforms for France’s military.

Barthelemy Thimonnier Machine

Later, in 1832, American mechanical engineer Walter Hunt innovated on it and developed the world's first lockstitch type machine, which was equipped with all the modern functions and is still in use today due to its design and durability.

WALTER MACHINE

Here we consider it necessary to mention this fact that Walter soon became interested in the machines he invented and sold all such invented machines for a few pennies.

Later, in 1842, Walter's invented machine was improved by introducing the feature of sewing with double-sided pressing to improve the sewing of clothes.

In the early nineteen century, the process of innovating the sewing machine invented by Barthélémy began once again and in the twenty century Continued until the beginning

In 1889, the famous American manufacturing company Singer Sewing Corporation introduced the first electric sewing machine. In its beginning, this machine was connected to an electric motor that rotated the handle with the help of a rubber band.

Later, in view of its popularity, this machine was further improved and moved towards consumer use with the help of various software and computers.

Thus, this journey of inventing and innovating the sewing machine, which began in the eighteenth century, is still ongoing today and is moving towards further innovation. It is said that keeping that invention alive and innovating it with each coming era is more difficult than inventing any useful thing.

We hope that you have found this article of ours interesting.

TURBINE STORY

In our previous article, we have discussed the invention and utility of wind turbine in detail to our esteemed readers, but without knowing the practical performance and working principles of the turbine, this example becomes like the English language that can be read and heard but not spoken.

So, let us move on to our main topic. Basically, the word turbine is derived from the Latin word turbo, which means "Vortex" and "Cap".

Here, to increase the knowledge of our esteemed readers, let us tell you that vortex refers to that special state of the flow of water or any liquid in which the flow takes the form of a shell commonly found in the sea, and cap is a special round-shaped rod.

Claude Burdin

In 1822, this name was proposed by Claude Burdin, a mining engineer from France. Later, in 1824, a student of Claude proposed this name in honor of his first water-powered turbine.

In practical terms, turbines are divided into two different types, the first is known as impulse and the second is known as reaction turbine.

IMPULSE TURBINE WORKING PRINCIPLE

Impulse turbines are connected to special types of water or gas nozzles, whose function is to create a special type of pressure in water or gas and with the help of this highly pressurized water or gas, the blades of the turbine are rotated. Impulse turbines are generally used for hydropower power plants or steam power generation.

REACTION TURBINE

On the other hand, reaction turbines work under the principles of Newton's Third Law and perform their work with the natural flow of water or gas without the help of any pressure or nozzles.

Here we will tell our esteemed readers that Newton says in his Third Law that every action has an equal reaction, on the basis of which reaction turbines perform their work. These turbines play an important role in power plants and marine propulsion systems.

Thus, these turbines have been divided into two different types according to the working method, but today's modern turbines in the world are capable of working in both modes simultaneously, depending on the operational conditions and the production demand. The performance of these modern turbines is tested with the help of various scientific formulas, software and simulation programs. Today, there are different types of turbines in the world that are playing a special role in the production demand of heavy industry, such as:

STEAM TURBINE: - Plays an important role in meeting the production demand of electricity in thermal power plants.

STEAM TURBINE

WIND TURBINE: - Plays an important role in meeting the electricity demand in various industries and villages and is known as an environmentally friendly invention in the 10th century.

WIND TURBINE

GAS TURBINE: - In today's modern era, these turbines are widely used in the manufacture of aircraft engines due to their relatively low weight and high power.

GAS TURBINE

WATER TURBINE:- This type of turbine is used to meet the demand for electricity generation in rivers and dams. These turbines are of special importance due to their environmental friendliness.

WATER TURBINE
