Howe was not the first to conceive of the idea of a sewing machine. Many other people had formulated the idea of such a machine before him, one as early as 1790, and some had even patented their designs and produced working machines, in one case at least 80 of them. However, Howe originated significant refinements to the design concepts of his predecessors, and on September 10, 1846, he was awarded the first United States patent (U.S. Patent 4,750) for a sewing machine using a lockstitch design. His machine contained the three essential features common to most modern machines:
a needle with the eye at the point,
a shuttle operating beneath the cloth to form the lock stitch, and
an automatic feed.
Despite securing his patent, Howe had considerable difficulty finding investors in the United States to finance production of his invention, so his elder brother Amasa Bemis Howe traveled to England in October 1846 to seek financing. Amasa was able to sell his first machine for £250 to William Thomas of Cheapside, London, who owned a factory for the manufacture of corsets, umbrellas and valises. Elias and his family joined Amasa in London in 1848, but after business disputes with Thomas and failing health of his wife, Howe returned nearly penniless to the United States. His wife Elizabeth, who preceded Elias back to the United States, died in Cambridge, Massachusetts shortly after his return in 1849.
Despite his efforts to sell his machine, other entrepreneurs began manufacturing sewing machines. Howe was forced to defend his patent in a court case that lasted from 1849 to 1854 because he found that Isaac Singer with cooperation from Walter Hunt had perfected a facsimile of his machine and was selling it with the same lockstitch that Howe had invented and patented. He won the dispute and earned considerable royalties from Singer and others for sales of his invention. Howe contributed much of the money he earned to the equip the 17th Connecticut Volunteer Infantry Regiment of the Union Army during the Civil War, in which Howe served during the Civil War as a private in Company D and regimental postmaster from August 14, 1862, to July 19, 1865.

Obtaining clothing is one of the most labor intensive occupations in pre-industrial societies. The Sewing machine was a great invention freeing many hours of work for other activities (the spinning machine was even more important in this respect but any society capable of manufacturing spinning machines is also capable of making (the significantly simpler) sewing machines).
machines are used to work
Scissors are a simple machine. A simple machine makes work easier to do. (not hard work) What type of simple machine are they? They are a lever. Levers have fulcrums or pivot points. The pivot point of the scissors are the crossing section.
Efficiency % = (work out / work in) * 100 (Work = force * distance)
A toothbrush is not a simple machine, it does not work on the principle of levers, effort, and load. It's not a machine at all in mathematical terms. A "machine" is that which performs "work", i.e. transfers or converts energy. You arm moving the toothbrush is a machine by this definition, however.
first you wash the material then next you let it run for a while
First, Issac singer invented the sewing machine and that didnt work so Walter hunt recreated it and when he finished it, it worked but he did not patent it because he thought it would cause unenployment.
Singer Sewing Machine late 1800's first machine had 800 moving parts, and Singer needed maintainence facilities so they franchised outlets to do service work

No.
An electric sewing machine does it's work by using electricity to move the needle up and down, and rotate the bobbin. The mechanical parts of a manual sewing machine, had to be set in motion by turning a handle, or pedal. An electric sewing machine has an electric motor attached to these rotating parts, by belt or gearing and operated by a foot switch. This makes it less tiring on the arms or feet, you can keep sewing faster and longer.
the first practical sewing machine is credited to the work of Englishman Thomas Saint in 1790
Yes
Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing 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, the sewing machine has vastly improved the efficiency and productivity of fabric and clothing industries.-Wikipedia
drop it from the seventh floor. quick and efficient. Answer two: Ha, ha the above answer might work, but I suggest you find/buy a manual for the machine and follow the guidelines. It is best to start with a working knowledge of sewing machines. You could probably get some help from your local sewing machine repair shop. Let the owner know what you want and see if you can get some help there.
A sewing machine is a textile machine used to stitch fabric, cards and other material together with thread. Sewing machines were invented during the first Industrial Revolution to decrease the amount of manual sewing 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, clothing and needle industries.Jordan Baird copyed this from wikipediahere is proofSewing machine
