Top 10 famous inventors and their inventions
At once, it was noticed abroad that he had treated India rubber to lose its stickiness, and he received international acclaim. He seemed on the high road to success, until one day he noticed that a drop of weak acid that fell on the cloth neutralized the alkali and immediately caused the rubber to become soft again. This proved to him that his process was not a successful one.

He therefore continued experimenting. After preparing his mixtures in his attic in New York , he would walk three miles to a mill in Greenwich Village to try various experiments. In the line of these, he discovered that rubber dipped in nitric acid formed a surface cure, and he made many products with this acid cure, which were held in high regard.
He even received a letter of commendation from American President Andrew Jackson. Exposure to harsh chemicals , such as nitric acid and lead oxide, adversely affected his health, and once he nearly suffocated in the gas generated in his laboratory. He survived, but the resulting fever came close to taking his life. Goodyear convinced a businessman, William Ballard, to form a partnership based on his new process Hubert , The two established manufacturing facilities to produce clothing, life preservers, rubber shoes, and a great variety of rubber goods, first at a factory on Bank Street in Manhattan, and then in Staten Island, where Goodyear also moved his family.
Just around this time, when everything looked bright, the financial panic of swept away the entire fortune of his associate and left Goodyear penniless as well. Goodyear's next move was to go to Boston, where he became acquainted with J. Haskins, of the Roxbury Rubber Company. Goodyear found him to be a good friend, who lent him money and stood by him when no one would have anything to do with the visionary inventor.
Chaffee, who had founded Roxbury, was also exceedingly kind and ever ready to lend a listening ear to his plans, and to assist him in a pecuniary way. About this time, it occurred to Mr. Chaffee that much of the trouble that they had experienced in working India rubber might come from the solvent that was used.
He therefore invented a huge machine for doing the mixing by mechanical means.
Charles goodyear biography and contribution of antoine new orleans: Charles Goodyear was an American inventor of the vulcanization process that made possible the commercial use of rubber. Goodyear began his career as a partner in his father’s hardware business, which went bankrupt in He then became interested in discovering a method of treating india rubber.
The goods that were made in this way were beautiful to look at, and it appeared, as it had before, that all difficulties had been overcome. Goodyear discovered a new method for making rubber shoes and received a patent that he sold to the Providence Company in Rhode Island. However, a method had not yet been found to process rubber so that it would withstand hot and cold temperatures and acids, and so the rubber goods were constantly growing sticky, decomposing, and being returned to the manufacturers.
Some time after this, Goodyear himself moved to Woburn, while continuing his experiments. Heyward had received, in a dream, a formula for hardening rubber by adding sulfur to gum, and exposing it to the heat of the Sun Iles , Goodyear encouraged Hayward to patent his new discovery, which he did. Goodyear then purchased the patent from him.
Using this process enabled Goodyear to produce better quality goods, but he also found that the process only hardened the outer layer of rubber objects. He thus became saddled with a large inventory of goods that were of no use to their purchasers. In the winter of , Goodyear noticed that some of the ruined rubber goods that had been returned to him, when accidentally brought into contact with a hot stove, charred in the same way that leather would, instead of melting.
He realized that some of the material was merely hardened, and not charred, by the fire. It thus appeared that heating the rubber that had been treated with sulfur would harden it throughout and remove its stickiness. This treated rubber would not soften at elevated temperatures, nor become inflexible at low temperatures, the way untreated rubber would.

He tried to bring this new discovery to the attention of friends and relatives, but they did not realize its significance Iles , When summer came around, he found that objects fashioned with rubber made by his new process did not become soft. Interestingly, the term "vulcanization" used to describe Goodyear's process was not coined by Goodyear himself but by James Brockedon, a rubber products manufacturer Iles , Now Goodyear was sure he had the key to the intricate puzzle that he had worked on for so many years.
For a number of years, he struggled and experimented and worked along in a small way, his family suffering with himself the pangs of extreme poverty. List of Partners vendors.

Goodyear attended the trial. If Hancock lost, Goodyear stood to have his own British patent application granted, allowing him to claim royalties from both Hancock and Moulton. Both had examined Goodyear's vulcanized rubber in , but several chemists testified that it would not have been possible to determine how it was made by studying it.
Hancock prevailed. The advantages of a career in life should not be estimated exclusively by the standard of dollars and cents, as is too often done. Man has just cause for regret when he sows and no one reaps. Goodyear died on July 1, , while traveling to see his dying daughter. After arriving in New York, he was informed that she had already died.
On February 8, , he was among six individuals selected for induction into the National Inventors Hall of Fame. In Woburn, Massachusetts , there is an elementary school named after him. The medal honors principal inventors, innovators, and developers whose contributions resulted in a significant change to the nature of the rubber industry.

Wikisource has original text related to this article: United States patent He approached a rubber goods manufacturer with an idea for a valve for an inflatable life buoy, but was advised that the company's own products were failing because of the material's inherent flaws.
Although it had outstanding qualities, it turned brittle and hard at low temperatures, and worse, into a gooey mass during warm weather. Goodyear was determined to solve the problems inherent in natural rubber. With no formal training in chemistry, his work was based on trial and error, experimenting with different methods of processing and additives such as magnesia.
The solution he discovered resulted partly from serendipity and partly from constant work. The breakthrough came in while Goodyear was exhibiting his most recent samples at a general store in Woburn, Massachusetts.
When he accidentally dropped a piece on a hot stove, it burned, but the uncharred part was transformed into a smooth, firm material that was not affected by high or low temperature. The additive in the sample was sulfur, but it took Goodyear several months to determine the right combination of heat, pressure, and sulfur to produce a stable compound.
Its first commercial use was as elastic thread in men's shirts. Goodyear vigorously promoted his product, but was forced to spend large sums of money defending his patent. In Britain , Thomas Hancock had received a patent for vulcanized rubber after Vulcan, the Roman god of fire a few months before Goodyear applied for his. Although Hancock offered to share his royalties, Goodyear took his claim of sole ownership to court and lost.
Goodyear invented a material that would eventually be used in thousands of ways and opened the door for a huge industry. Today there is one rubber tree for every two people on Earth. Despite this, he died destitute in New York on July 1, Although the Goodyear Tire and Rubber Company was named in his honor, Goodyear's descendants had little to do with the rubber industry after his death.

His father was an inventor, manufacturer, and merchant of hardware, especially of farm tools. When Charles was 17, his father sent him to Philadelphia to learn the business, and at 21 he returned to become his father's partner. He married at the age of 24 and 2 years later opened a store in Philadelphia. In a lifetime of financial distress began for the Goodyears when both father and son went bankrupt.
On a trip to New York City that year, Goodyear visited a store that sold goods made of india rubber, a product only recently manufactured in America.

Inspired by the possibilities of the material, he determined to improve its usefulness. His first experiments were carried out in jail, where he had been sent for failure to pay his debts. In Goodyear settled his family on the charity of friends near New Haven and went to New York to continue his work. He received a patent for an improved type of rubber and was able to find a modest amount of financial backing.
After moving to Massachusetts, he met Nathaniel M. Hayward, an inventor, whose patent on a process for mixing sulfur with rubber he bought. Goodyear intended to combine the new patented process with his old one, which involved coating rubber with an acid and metal. During an argument one day in his shop, Goodyear accidentally dropped a piece of the sulfur-impregnated rubber on a hot stove.
Instead of melting, it merely charred slightly. Realizing the importance of this two major drawbacks to using rubber were that it melted at high temperatures and tended to harden at low temperatures , he began experiments to discover the proper proportions and method of baking the new type of rubber, which he called "vulcanized. He claimed to have found more than uses for rubber and received patents in all countries except England, where Thomas Hancock had invented vulcanization in A shorter study is in John C.
