A sewing machine is a textile A textile is a flexible material consisting of a network of natural or artificial fibres often referred to as thread or yarn. Yarn is produced by spinning raw wool fibres, linen, cotton, or other material on a spinning wheel to produce long strands.

Yarn is produced by spinning raw wool fibres, linen, cotton, or other material on a spinning wheel to produce long strands. Textiles are formed by weaving, knitting, crocheting, knotting, or pressing fibres together or other material together with thread. Sewing machines were invented during the first Industrial Revolution The Industrial Revolution was a period from the 18th to the 19th century where major changes in agriculture, manufacturing, mining, transport and technology had a profound effect on the socioeconomic and cultural conditions starting in the United Kingdom, then subsequently spreading throughout Europe, North America, and eventually the world. The to decrease the amount of manual sewing Sewing is the craft of fastening or attaching objects using stitches made with needle and thread. Sewing is one of the oldest of the textile arts, arising in the Paleolithic Era. Before the discovery of spinning yarn or weaving fabric, archaeologists believe Stone Age people across Europe and Asia sewed fur and skin clothing using bone, antler or work performed in clothing companies. Since the invention of the first working sewing machine, generally considered to have been the work of Englishman Thomas Saint in 1790,[1] the sewing machine has vastly improved the efficiency and productivity of fabric and clothing industries.

Modern sewing machines are designed in such a way that the fabric easily glides in and out of the machine without the hassle of needles and thimbles and other such tools used in hand sewing, automating the process of stitching and saving time.
Industrial sewing machines, by contrast, are larger, faster, more complex, and more varied in their size, cost, appearance, and task.
The fabric shifting mechanism may be a workguide or may be pattern-controlled (e.g., jacquard The Jacquard loom is a mechanical loom, invented by Joseph Marie Jacquard in 1804, that simplifies the process of manufacturing textiles with complex patterns such as brocade, damask, and matelasse. The loom is controlled by punched cards with punched holes, each row of which corresponds to one row of the design. Multiple rows of holes are punched type). Some machines can create embroidery-type stitches. Some have a work holder frame. Some have a workfeeder that can move along a curved path, while others have a workfeeder with a work clamp. Needle guards, safety Safety is the state of being "safe" , the condition of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological, educational or other types or consequences of failure, damage, error, accidents, harm or any other event which could be considered non-desirable. This can take the form devices to prevent accidental needle-stick A needlestick injury is a percutaneous piercing wound typically set by a needle point, but possibly also by other sharp instruments or objects. Commonly encountered by people handling needles in the medical setting, such injuries are an occupational hazard in the medical community. These events are of concern because of the risk to transmit blood- injuries, are often found on modern sewing machines.

History and development
In 1791 British inventor Thomas Saint was the first to patent a design for a sewing machine.[2] His machine was meant to be used on leather and canvas. A working model was never built.
In 1814 an Austrian tailor, Josef Madersperger, presented his first sewing machine, the development of which started in 1807.
In 1830 a French tailor, Barthélemy Thimonnier, patented a sewing machine that sewed straight seams using chain stitch. By 1841, Thimonnier had a factory of 80 machines sewing uniforms for the French Army.[citation needed] The factory was destroyed by rioting French tailors afraid of losing their livelihood. Thimonnier had no further success with his machine.
The lockstitch The lockstitch uses two threads, an upper and a lower. The upper thread runs from a spool kept on a spindle on top of or next to the machine, through a tension mechanism, a take-up arm, and finally through the hole in the needle. The lower thread is wound onto a bobbin, which is inserted into a case in the lower section of the machine. To make one sewing machine was invented by Walter Hunt Walter Hunt was an American mechanic. He lived and worked in New York state. Through the course of his work he became renowned for being a prolific inventor, notably of the sewing machine (1833), safety pin (1849), a forerunner of the Winchester repeating rifle, a successful flax spinner, knife sharpener, streetcar bell, hard-coal-burning stove, in 1833.[3] His machine used an eye-pointed needle (with the eye and the point on the same end) carrying the upper thread and a shuttle carrying the lower thread. The curved needle moved through the fabric horizontally, leaving the loop as it withdrew. The shuttle passed through the loop, interlocking the thread. The feed let the machine down, requiring the machine to be stopped frequently and reset up. Hunt eventually lost interest in his machine and sold it without bothering to patent it. In 1842, John Greenough patented the first sewing machine in the United States.
Elias Howe Elias Howe was an American inventor and sewing machine pioneer. He was born in Spencer, Massachusetts, born in Spencer, Massachusetts, created his sewing machine in 1845, using a similar method to Hunt's, except the fabric was held vertically. The major improvement he made was to have the needle running away from the point, starting from the eye. After a lengthy stint in England trying to attract interest in his machine he returned to America to find various people infringing his patent. He eventually won his case in 1854 and was awarded the right to claim royalties from the manufacturers using ideas covered by his patent.
Isaac Merritt Singer Isaac Merritt Singer was an inventor, actor, and entrepreneur. He made important improvements in the design of the sewing machine and was the founder of the Singer Sewing Machine Company. Singer is most famous now for his invention of the Singer sewing machine - yet many had patented sewing machines before him. The reason his sewing machine has become synonymous with the sewing machine. Trained as an engineer, he saw a rotary sewing machine being repaired in a Boston shop. He thought it to be clumsy and promptly set out to design a better one. His machine used a flying shuttle instead of a rotary one; the needle was mounted vertically and included a presser foot to hold the cloth in place. It had a fixed arm to hold the needle and included a basic tensioning system.
This machine combined elements of Thimonnier's, Hunt's, and Howe's machines. He was granted an American patent in 1851 and it was suggested he patent the foot pedal (or treadle) used to power some of his machines; however, it had been in use for too long for a patent to be issued. When Howe learned of Singer's machine he took him to court. Howe won and Singer was forced to pay a lump sum for all machines already produced. Singer then took out a license under Howe's patent and paid him $1.15 per machine. Singer then entered a joint partnership with a lawyer named Edward Clark, and they formed the first hire-purchase Hire purchase is the legal term for a contract, in this persons usually agree to pay for goods in parts or a percentage at a time. It was developed in the United Kingdom and can now found in China, Japan, Malaysia, India, Australia, and New Zealand. It is also called closed-end leasing. In cases where a buyer cannot afford to pay the asked price (time payment) scheme to allow people to afford to buy their machines.
Meanwhile Allen B. Wilson had developed a shuttle that reciprocated ("vibrated") in a short arc, which was an improvement over Singer's and Howe's. However, John Bradshaw had patented a similar device and was threatening to sue. Wilson decided to try a new method. He went into partnership with Nathaniel Wheeler Nathaniel Wheeler was the founder and executive of many companies in Bridgeport, CT, United States, in the 1800s. He owned numerous manufacturing companies and land all over, around Bridgeport, Ct including the site of his mansion on Golden Hill Street, presently occupied by the City Hall after his long time mansion was pulled down in the 1950s to produce a machine with a rotary hook instead of a shuttle. This was far quieter and smoother than the other methods, and the Wheeler and Wilson Company produced more machines in 1850s and 1860s than any other manufacturer. Wilson also invented the four-motion feed mechanism; this is still seen on every machine today. This had a forward, down, back, and up motion, which drew the cloth through in an even and smooth motion. Charles Miller patented the first machine to stitch buttonholes (U.S. Patent 10,609).
Through the 1850s more and more companies were being formed and were trying to sue each other. This triggered a patent thicket known as the Sewing Machine War.[4] In 1856 the Sewing Machine Combination was formed, consisting of Singer, Howe, Wheeler and Wilson, and Grover and Baker. These four companies pooled their patents, meaning that all the other manufacturers had to obtain a license and pay $15 per machine. This lasted until 1877 when the last patent expired.
In the 1840s a machine shop was established at the Merrow mill to develop specialized machinery for the knitting operations. In 1877 the world’s first crochet machine was invented and patented by Joseph M. Merrow, then-president of the company. This crochet Crochet is a process of creating fabric from yarn or thread using a crochet hook. The word is derived from the French word "crochet", meaning hook. Crocheting, similar to knitting, consists of pulling loops of yarn through other loops. Crochet differs from knitting in that only one loop is active at one time (the sole exception being machine was the first production overlock An overlock stitch sews over the edge of one or two pieces of cloth for edging, hemming or seaming.

The Merrow Machine Company Merrow Sewing Machine Company is a manufacturer of sewing machines, established in 1838 as the Merrow Company by J. Makens Merrow. Originally a gunpowder manufacturer, in 1837 the company built a knitting mill, and in 1887 evolved to design, build and market sewing machines exclusively. Best known for inventing the overlock sewing machine, it was went on to become one of the largest American Manufacturers of overlock An overlock stitch sews over the edge of one or two pieces of cloth for edging, hemming or seaming.

An overlock sewing machines, and continues to be a global presence in the 21st century as the last American overlock sewing machine manufacturer.
James Edward Allen Gibbs James Edward Allen Gibbs was a farmer, inventor, and businessman from Rockbridge County in the Shenandoah Valley in Virginia. On June 2, 1857, he was awarded a patent for the first chain-stitch single-thread sewing machine. In partnership with James Willcox, Gibbs became a principal in Willcox & Gibbs Sewing Machine Company. Willcox & (1829-1902), a farmer from Raphine in Rockbridge County, Virginia patented the first chain-stitch single-thread sewing machine on June 2, 1857. In partnership with James Wilcox, Gibbs became a principal in Wilcox & Gibbs Sewing Machine Company. Wilcox & Gibbs commercial sewing machines are still used in the 21st century.
In 1885 Singer patented the Singer Vibrating Shuttle sewing machine, which used Allen B. Wilson's idea for a vibrating shuttle and was a better lockstitcher than the oscillating shuttles of the time. Millions were produced until finally superseded by rotary shuttle machines in the 20th century.
In 1905 Merrow won a lawsuit against Wilcox & Gibbs for the rights to the original crochet stitch The blanket stitch is a stitch used to reinforce the edge of thick materials. Depending on circumstances, it may also be called a whip stitch or a crochet stitch. It is defined as "A decorative stitch used to finish an unhemmed blanket. The stitch can be seen on both sides of the blanket.".
Sewing machines continued being made to roughly the same design, with more lavish decoration appearing until well into the 1900s when the first electric machines started to appear. The first electric machines were developed by Singer Sewing Co. and introduced in 1889.[5] At first these were standard machines with a motor strapped on the side. As more homes gained power, these became more popular and the motor was gradually introduced into the casing.
Described by some as the "Maytag of sewing machines" the Necchi sewing machines from Italy were coveted for their aesthetically pleasing designs.
In 1946, the first Toyota sewing machine was built under the strict supervision of Toyota founder, Mr. Kiichiro Toyoda. Mr. Toyoda had a strong belief that home-use products must be "functional yet beautiful".
In 1987, Orisol (Israel) pioneered the introduction of the first vision controlled computerized industrial sewing machines into the shoe making world. The addition of vision sense (sophisticated image processing) to the computer controlled sewing systems dramatically enhanced the accuracy of the multi-part sewing process, correcting or compensating in real time for any deflection, deformation or dynamic movement of the sewn parts as compared to the results from conventional computerized sewing machines.
Modern machines may be computer controlled and use stepper motors or sequential cams to achieve very complex patterns. Most of these are now made in Asia and the market is becoming more specialized.
Stitch formation
A rotary hook sewing machine creating a lockstitchSewing machines can make a great variety of plain or patterned stitches. Ignoring strictly decorative aspects, over three dozen distinct stitch formations are formally recognized by the ISO 4915:1991 standard (for a summary see [3], [4], or [5]), involving one to seven separate threads to form the stitch.
Plain stitches fall into four general categories: lockstitch The lockstitch uses two threads, an upper and a lower. The upper thread runs from a spool kept on a spindle on top of or next to the machine, through a tension mechanism, a take-up arm, and finally through the hole in the needle. The lower thread is wound onto a bobbin, which is inserted into a case in the lower section of the machine. To make one, chainstitch Chain stitch is a sewing and embroidery technique in which a series of looped stitches form a chain-like pattern. Chain stitch is an ancient craft - examples of surviving Chinese chain stitch embroidery worked in silk thread have been dated to the Warring States period . Handmade chain stitch embroidery does not require that the needle pass, overlock An overlock stitch sews over the edge of one or two pieces of cloth for edging, hemming or seaming.

Lockstitch
Lockstitch is the familiar stitch performed by most household sewing machines and most industrial "single needle" sewing machines from two threads, one passed through a needle and one coming from a bobbin or shuttle. Each thread stays on the same side of the material being sewn, interlacing with the other thread at each needle hole by means of a bobbin driver. As a result, a lockstitch can be formed anywhere on the material being sewn; it does not need to be near an edge.
Main article: Lockstitch The lockstitch uses two threads, an upper and a lower. The upper thread runs from a spool kept on a spindle on top of or next to the machine, through a tension mechanism, a take-up arm, and finally through the hole in the needle. The lower thread is wound onto a bobbin, which is inserted into a case in the lower section of the machine. To make oneChainstitch
Chainstitch was used by early sewing machines and has a major drawback: the stitch can easily be ripped out, and can rip out by itself if the thread breaks at any point.[6] People soon realized a better stitch was needed, and it was found in the lockstitch The lockstitch uses two threads, an upper and a lower. The upper thread runs from a spool kept on a spindle on top of or next to the machine, through a tension mechanism, a take-up arm, and finally through the hole in the needle.

The chainstitch is still used today in clothing manufacture, though due to its major drawback it is generally paired with an overlock An overlock stitch sews over the edge of one or two pieces of cloth for edging, hemming or seaming.

Handmade chain stitch embroidery does not require that the needle passOverlock
Also known as serging or serger stitch.
Varieties of overlock stitch can be formed with one to four threads, one or two needles, and one or two loopers. Overlock sewing machines are usually equipped with knives that trim or create the edge immediately in front of the stitch formation. Household and industrial overlock machines are commonly used for garment seams in knit or stretchy fabrics, for garment seams where the fabric is light enough that the seam does not need to be pressed open, and for protecting edges against raveling. Machines using two to four threads are most common, and frequently one machine can be configured for several varieties of overlock stitch. Overlock machines with five or more threads usually make both a chainstitch with one needle and one looper, and an overlock stitch with the remaining needles and loopers. This combination is known as a "safety stitch". Household overlock machines are widely used.
Overlock can only be formed at the edge itself, where one or more threads pass over the edge.

Usually an overlock sewing machine will cut the edges of the cloth as they are fed through , though some are made without cutters. The inclusion of automated cutters allows overlock machines to create finished seams easily and quickly. An overlockCoverstitch
Coverstitch is formed by two or more needles and one or two loopers. Like lockstitch and chainstitch, coverstitch can be formed anywhere on the material being sewn. One looper manipulates a thread below the material being sewn, forming a bottom cover stitch against the needle threads. An additional looper above the material can form a top cover stitch simultaneously. The needle threads form parallel rows, while the looper threads cross back and forth all the needle rows. Coverstitch is so-called because the grid of crossing needle and looper threads covers raw seam edges, much as the overlock stitch does. It is widely used in garment construction, particularly for attaching trims and flat seaming where the raw edges can be finished in the same operation as forming the seam. Machines with three needles are most common, and can be configured to use any two or all three of the needles. Machines with six or more needles are often used for applications like fastening elastic waistbands to garments. Household coverstitch machines are fairly rare, but are becoming more readily available.
Feed mechanisms
Besides the basic motion of needles, loopers and bobbins A bobbin is a spindle or cylinder, with or without flanges, on which wire, yarn, thread or film is wound. Bobbins are typically found in sewing machines, cameras, and within electronic equipment, the material being sewn must move so that each cycle of needle motion involves a different part of the material. This motion is known as feed, and sewing machines have almost as many ways of feeding material as they do of forming stitches. For general categories, we have: drop feed, needle feed, walking foot, puller, and manual. Often, multiple types of feed are used on the same machine. Besides these general categories, there are also uncommon feed mechanisms used in specific applications like edge joining fur, making seams on caps, and blindstitching.
