Inventions I studied and how they help the world
#1. John Deere invented the steel plow in 1837 when the Middle-West was being settled. The soil was different than that of the East and wood plows kept breaking. Where was it created or discovered? He invented it in Grand Detour, Illinois where he had settled. Impact on Economy The steel plow that John Deere invented benefited farmers because it allowed them to cut furrows in thick sticky Midwest soil. John Deere was an inventor, and a blacksmith. In 1837 he was working with steel and decided he was going to make a steel plow for farmers. John Deere was an American inventor and manufacturer. After his invention of the steel plow, he eventually became one of the worlds greatest plow makers! The cost of the steel plow in 1837 was $10 to $12 dollars. Today most steel plows cost well over $100 dollars. A plough (UK) or plow is a tool or farm implement used in farming for initial cultivation of soil in preparation for sowing seed or planting to loosen or turn the soil. Ploughs were traditionally drawn by working animals such as horses or cattle, but in modern times are drawn by tractors. It was used for farming to break up tough soil without soil getting stuck to it. When was it invented or first used? John Deere invented the steel plow in 1837 when the Middle-West was being settled. The soil was different than that of the East and wood plows kept breaking.–
#2. Sir Rowland Hill
A schoolmaster from England, Sir Rowland Hill invented the adhesive postage stamp in 1837, an act for which he was knighted. Through his efforts the first stamp in the world was issued in England in 1840. Roland Hill also created the first uniform postage rates that were based on weight rather than size. Rowland Hill Invents Adhesive Postage Stamps. A schoolmaster from England, Sir Rowland Hill invented the adhesive postage stamp in 1837, an act for which he was knighted with the new policy of charging by weight, more people began using envelopes to mail documents. Although a number of people laid claim to the concept of the postage stamp, it is well documented that stamps were first introduced in the United Kingdom of Great Britain and Ireland on 1 May 1840 as a part of postal reforms promoted by Sir Rowland Hill. On March 3, 1847, Congress authorized United States postage stamps. The first general issue postage stamps went on sale in New York City, July 1, 1847. One, priced at five cents, depicted Benjamin Franklin. The other, a ten-cent stamp, pictured George Washington. When World War I ended at the end of 1918, the rate was lowered to its prewar level of one cent. The postal rate was raised briefly from 1 cent to 2 cents in 1917-1919 and in 1925-1928; the conclusive raise to 2 cents was in 1951. The birth of the postage stamp dates back to May 6, 1840, when Britain issued its first stamp, the “Penny Black.”
#3. 1839 The steam shovel was invented by William Otis, who received a patent for his design in 1839. The first machines were known as ‘partial-swing’, since the boom could not rotate through 360 degrees. They were built on a railway chassis, on which the boiler and movement engines were mounted. Otis was an American inventor of the steam shovel. Otis received a patent for his creation on February 24, 1839. In 1839 William Smith Otis, civil engineer of Philadelphia, Pennsylvania, was issued a US patent for the steam shovel (No. … On February 24, 1839, the patent behind number 1089 officially entered. With the help of his engineer friend, Charles H. French, he built the first steam shovel in 1835 in Canton, Massachusetts. He patented the device in 1839 and it became the earliest known bucket excavator used for removing dry earth. By 1840, the Otis shovel was a North American treasure. A steam shovel is a large steam-powered excavating machine designed for lifting and moving material such as rock and soil. It is the earliest type of power shovel or excavator. They played a major role in public works in the 19th and early 20th century, being key to the construction of railroads and the Panama Canal.
#4.In the year 1852 Goodyear went to Europe, a trip that he had long planned, and saw Thomas Hancock, then in the employ of Charles Macintosh & Company. Hancock claimed to have invented vulcanization independently, and received a British patent, initiated in 1843, but finalized in 1844. Vulcanization or vulcanisation is a chemical process for converting natural rubber or related polymers into more durable materials by the addition of sulfur or other equivalent curatives or accelerators. These additives modify the polymer by forming cross-links (bridges) between individual polymer chains. In its simplest form, vulcanization is brought about by heating rubber with sulfur. The process was discovered in 1839 by the U.S. inventor Charles Goodyear, who also noted the important function of certain additional substances in the process. The fact that rubber can be made either soft or hard greatly increases the range of things we can use it for. Soft and stretchy latex is used in all kinds of everyday things, from pencil erasers, birthday balloons, and condoms to protective gloves, adhesives, and paints. Rubber is a name given to a lot of different polymers that are all elastomers. That means they can be stretched out and they will return to their original shape when you let go. The first rubber was the natural kind from the sap of hevea trees in Central America.
