Elisha Otis was born on August 3, 1811 Halifax, Vermont. He died on April 8, 1861, but not without changing the world as we knew it. The Safety Hoist, that is how he changed the world. The elevator had been around for a while, but many people did not like to use it, especially construction crews, as it was unstable and often fell and broke. Otis made the “safety hoist; the first elevator equipped with an automatic safety device to prevent it from falling if the lifting chain or rope broke. (Britannica) “[the safety hoist]..safety device consisted of a used wagon spring that attached to both the top of the hoist platform and the overhead lifting cable...under ordinary circumstances, the spring was kept in place by the pull of the platforms weight …show more content…
When this occurred, both ends of the spring would engage the saw-toothed ratchet-bar beams that Otis had installed on either side of the shaft, thereby bringing the falling hoist platform to a complete stop.” (ASME) Elisha Otis displayed his creation at the Crystal Palace Exposition in New York City in 1854. One year prior to the exposition Otis opened his own factory in Yonkers on September 20, 1853. He already had two large orders but once the exposition took place he began to get more and more orders. In 1857 Otis equipped a five story building with the first passenger elevator, it was a completely surrounded chamber with the same mechanics as the freight elevators he developed. Elisha Otis started a business with his two sons called Union Elevator and General Machine Works Company, later renamed Otis Brothers and Company. His safety elevators were used in tall landmarks, the Eiffel Tower, the Chrysler and Empire State Building. Elisha Otis made a few other inventions in his lifetime, the steam plow, the bake/rotary oven, the railway safety brake and the oscillating steam …show more content…
Now almost every two story business and commercial building has an elevator. The Otis Brothers and Company are still around and they installed elevators in the Eiffel Tower and the Washington Monument. In 1913 the The Otis Brothers and Company installed an elevator in a 60 story, Woolworth Building NYC which was the tallest building at the time. Elisha Otis and his inventions greatly impacted our way of life. Now it’s hard to think of a building without an elevator, one that is safe and will not come crashing down. Elevators are everywhere, schools, banks, and some people even have them in their houses. Elevators are a very normal thing to have, no one bats an eye when a school has an elevator or when an apartment building has one, but no one thinks of how the elevator came about and who made it same enough for people to ride
The book Safety 24/7 was a book basically about safety in an industrial workplace. The book explained many safety tips to improve a safe working environment. There were a few main characters in this book that were very easily to understand their purpose in the story. The first character that appeared in this story is Kurt Bradshaw. He was promoted to the manager of worldwide safety. His great leadership skills and motivational techniques had put him in this new position. Kurt was very excited for the job and ready for it, but he was not too familiar about any safety tasks that could improve the workplace.
Answer – If there is ever any doubt that health and safety/risk management procedures and practices are not being adhered to, then immediate action is required. Within my workplace we have a responsible individual who ensures that risk assessments
The effect of smaller government safety nets on families is drastic. The United States is one of the few countries left in the world that has yet to understand the importance of strong supports for the primary building block of our society. By continuing to balance our competing ideals of individualism against marriage and family we are putting the very foundations of our country at risk. Our current federal safety net is made up of many individual policies and programs. “They are generally independent of each other and attack a single aspect of poverty. Taken as a whole they represent a challenging matrix for the poor to use and the American taxpayer to understand” ("Safety Net Programs - Federal Safety Net," n.d.).
Albert Einstein was a German-born physicist who developed the general theory of relativity. He is considered one of the most influential physicists of the 20th century. In 1921, he won the Nobel Prize for physics for his explanation of the photoelectric effect and immigrated to the U.S. in the following decade after being targeted by the Nazis. Became an official citizen of the U.S., Einstein died on April 18, 1955, in Princeton, New Jersey, and all his achievements are considered as a part of the American history. As another example, Igor Sikorsky, who was a Ukrainian aeronautics engineer and inventor known for crafting the first four-engine plane and the first working helicopter. Sikorsky emigrated to the United States in 1919 and in 1925 formed The Sikorsky Manufacturing Corporation located in Long Island, New York. The company evolved into The Sikorsky Aviation Corporation. His company later became a division of United Aircraft Corporation and United Technologies Corporation. A recipient of many honors and accolades, Sikorsky, the head of one of America's pioneering aerospace companies, died on October 26, 1972, in Easton, Connecticut. In the age of digital technology, humanity enjoys all the benefits of designers and device creators, among whom is an immigrant co-founder of the world's most popular search engine and a media giant Google –
George Pullman was an American industrialist and inventor. His father moved buildings out of the way of the Erie Canal. George took over the business in 1853. Later he won a contract with the state of New York to move 20 buildings out of the way. After this he came up with the idea to manufacture and lease railroad cars on the growing railroad industry. After being unsatisfied with sleepers and passenger cars, he created the Pullman Sleeper. These cars were immediately successful
Second of all,One inventor made elevator and his name was made Alexander Miles. Early elevators were different from the mostly automated devices we're familiar with today. Passengers had to manually open and close the elevator doors, as well as the door leading to the elevator shaft. If anyone forgot to close the shaft door, other passengers could fall down the shaft when expecting to step into the elevator. Miles invented a mechanism that
His interest was sparked by William Sturgeon’s first electromagnet that he built in 1825 in London. In 1830, Henry built the world’s most powerful electromagnet, the Albany Magnet, lifting as much as 750 pounds of metal at a time, a huge increase on the 9 pounds achieved by Sturgeon. In the months of June and July of 1831, Henry built an electromagnet for Penfield and Taft Ironworks in Ironville, NY. Henry was already familiar with the mines in the area as he was seeking pure soft iron to work with in his experiments. The device developed for ore separation is the first commercial use of electricity in history. By 1831 Henry’s electromagnets could lift more than 2000 pounds. In 1833, after moving from Albany to Princeton, Henry built a new record-breaking electromagnet capable of lifting 3300 pounds. (famous
Granville Woods was a black inventor that made inventions like the automatic brake and egg incubator and made improvements to the Telephone, Telegraph, Phonograph, and Safety Circuits. At age 10 Woods worked at a machine shop repairing railroad equipment and machinery which helps him understand railroads and machines at an extremely high level. After two years of college Woods went to work at a British steamship called Ironsides as an engineer. Two years after that he worked at D&S Railroads. Despite all the work he put in Woods was denied promotions and opportunities because he was black. He was so fed up he decided to form the Woods Railway Telegraph Company with his brother Lyates. Three year after Woods formed his company
After the completion of the construction project, Otis was set to move on with his life and travel with his family to California in hopes of striking it rich. However, his invention had attracted the interest of a number of construction companies who requested that Otis build them a safe lifting system. Otis decided that he would stay in New York and would go on to build the first passenger elevator. The development of the elevator had previously been inhibited by safety concerns, but Otis was able to create the first safe passenger
Sarah E. Goode was one of the first black female inventors to receive a patent from the United States. Sarah invented the “folding bed” after receiving her freedom after the Civil War and becoming an entrepreneur. She created the idea of the folding bed because she realized that her customers [lived] in small apartments. When it was not being used as a bed the bed doubles as a desk. She received a patent for her invention in July 14, 1985. As someone born into slavery in 1850, she understood ways to make living in working-class environment easier. She opened a furniture store with her husband, Archibald, in Chicago after the Civil War. Sarah and her husband married in 1880. The cabinet bed was like an antecedent for the murphy bed. Sarah E.
The first engines used in America were purchased from England. The first railroad built in the US was the Baltimore and Ohio railroad. Construction started in July 1828 and it was built there because Baltimore was the 3rd largest state, and they didn’t have a canal for easy transportation. The railroad was built to help them compete with New York and the Erie Canal (“Early American Railroads”, web). There were more than 5 operating railroads by 1835 and would grow even more
Joseph Winters, born in 1816, made the fire escape ladder in 1878. Then 100 years later, died of heart disease and is buried in Chambersburg, Pa . On May 7, 1878, the fire escape ladder was patented by Joseph Winters. Joseph Winters invented a fire escape ladder mounted onto a horse drawn wagon. Winters noticed that firemen had to take ladders off of their wagons to climb to windows, rescue people, and spray water on fires.
Hoover boards has been a hot topic these days. Hoover boards have been rumored around since the 1950's. For the most part Hoover boards have been banned from even being displayed for the public. It was firstly introduced in a movie call "Back to the Future"; a movie that took place decades after our time. The flying Hoover board concept was introduced during the Olympus. Other forms of technology have been created to recreate this concept. The Segway was introduced as an automatic two wheeled device that tourists were taking to your big cities. As these grand technologies continued to emerge , more and more people began to voice their opinions.
The first successful aircraft catapult was used on November 12 1915,by Theodore Gordon Ellyson. The US Navy currently uses steam catapults but want to replace them with “EMALS”, electromagnetic aircraft launch system. According to “The Hill” Trump said he wants the steam catapults instead of the new catapults because it's less money and that the EMALS are no good. The steam catapults were developed in the 1950’s. Steam catapults have disadvantages they can't launch as many planes and it's also hard to control when launching different kinds of planes.According to “General Atomics” Gerald R. Ford is the first aircraft carrier to use EMALS. EMALS has some advantages such as reduced thermal signature,reduced topside weight,and increase launch.
Health and Safety Regulations aim to improve safety in workplaces, making employers and employees equally responsible for ensuring that they protect themselves and others from accident and injury. The regulations refer to such things as clean kitchens, safety guards on machinery etc., If an employee is injured at work because of breaches of these rules then compensation can be awarded. Most health and safety legislation places place the responsibility of health and safety on the employers. The responsibilities may however be delegated to other competent persons such as fire warders, first aiders and care takers but the employer still
