Jack Johnson was an amazing man that changed history. His contribution to the world (the wrench) is still used widely throughout the world. The world and all things are either created by nature or man made, if man made it was probably constructed using hardware tools maybe including a wrench. Jack Johnson invented a history changing invention and patented it on April 18, 1922. This invention still changes lives today by putting together many of our belongings. Things like cars are repaired using a wrench and bicycles are made using wrenches. Things like chairs, beds, tables, and shelves are usually either created or fixed using a wrench and other hardware materials.…

1. I think that going under the water ultimately killed the Underhills. If they had not been in water and loss conscience and or had heart attack etc. they may have regained conscience instead they were in water and therefore drowned.…
In the late 1700s, in addition to inventing the cotton gin, Eli Whitney also came up with the idea for interchangeable parts. This was the pre-manufacturing of machinery pieces that could be quickly assembled to make a functioning piece of equipment, such as a gun. Before Whitney, each gun had to be handcrafted, and each one was different in its assembly. This meant that it took a long time for them to be made or repaired. When Congress voted for a war with France in 1797, Whitney saw an opportunity to market his idea because he knew a lot of guns would be needed to fight the war. Whitney obtained a federal grant from the government in 1798 to build 10,000 muskets for the army in 2 years, which was a ridiculous proposal for the time period. He applied the idea of interchangeable parts to the production of firearms and created a machine that could make exact copies of individual components of guns. These could then be assembled faster and more efficiently, thus saving the government time and money. Although it took him eight years to complete the project instead of two, Thomas Jefferson and John Adams among others were both impressed with Whitney’s invention when he came to the Washington area to defend it.…
The first invention by Eli Whitney while in Georgia in 1793 is a simple machine that separates cotton fibers from the seeds. The modern mechanical cotton gin was invented in the United States in 1793. The gin has wire teeth mounted on a boxed rotating cylinder that, pulls cotton fiber through small grates to separate the seeds, while a rotating brush removes lint from the spikes to avoid jams. Eli applied for the invention on October 28, 1793; the invention was granted on March 14, 1794, but was not validated until 1807.…
There is some probable cause that the reason for the Underbill’s death is closely associated with the fact that they are drunk thus delimiting their normal state of alertness leading them to drown.…
The Waterhouse project was an inquiry that looked at children’s abuse within children’s homes in 1996 that was opened by the welsh secretary. It all started when Sir Ronald Waterhouse who was a retired high court judge opened a tribunal of enquiry into child abuse in North Wales in 1974. It was a huge abuse scandal and took evidence from 575 witnesses, including 259 complainants alleging abuse when they were in care. Over 9500 social services files were made available and over 3500 police statements were scrutinized. There were well over 40 000 pages of evidence of complaints for just 40 homes and foster placements.…
In 1794, U.S.-born inventor Eli Whitney patented the cotton gin, a machine that revolutionized the production of cotton by greatly speeding up the process of removing seeds from cotton fiber. By the mid-19th century, cotton had become America's leading export. Despite its success, the gin made little money for Whitney due to patent issues. Also, his invention offered Southern planters a justification to maintain and expand slavery even as a growing number of Americans supported its abolition. Based in part on his reputation for creating the cotton gin, Whitney later secured a major contract to build muskets for the U.S. government. Through this project, he promoted the idea of interchangeable parts--standardized, identical parts that made for faster assembly and easier repair of various devices. For his work, he is credited as a pioneer of American manufacturing. This machine revolutionized the process of separating cotton from its seed, making it dramatically faster and less expensive to turn picked cotton into usable cotton for textiles. Eli Whitney invented the gin in 1794, and by 1850 the tool had changed the face of Southern agriculture.…
The Gatling Gun was created and named after Richard J. Gatling (Richard). Born on September 12, of 1818, he grew up helping his father invent the cotton machine, which would pluck the seeds from the cotton automatically. In 1850 he attended Ohio Medical Collage, that same year he invented the hemp-breaking machine. Seven years later he also invented the steam plow. When the Civil War erupted he began working on a gun that would…

Hiram S. Maxim, who was working with an engineering works in Fitchburg, Massachusetts, invented the Maxim machine-gun in 1884. Hiram Maxim was born in Sangersville, Maine on February 5, 1840. His first patented inventions included models of electric lamps and gas appliances, and curling irons.…

Every successful enterprise had to start somewhere. Some encountered more humble at the beginning, some less. Some had the advantage of large capital investments, some started with a couple of bucks. Some had a professional office or laboratory to their disposal and some launched a big entrepreneurial idea from the back of the garage.…
