Karl Benz The-wps Office.doc

Karl Benz the inventor First Automobile According to www.autodesk.com, Karl was born into a poor and mis-fortuned family. His father died when Benz was two years old and he spent the rest of his years raised by his mother. Thankfully she prioritized education and saw Benz through university at the age of 15. He later went on to graduate with a degree in mechanical engineering. Following his graduation from university, Karl rolled through a series of engineering and construction jobs searching for his calling. He ended up settling in Mannheim, Germany, where he partnered with August Ritter to open an iron foundry and sheet-metal workshop. The First Automobile On January 29, 1886, Carl Benz applied for a patent for his “vehicle powered by a gas engine.” The patent – number 37435 – may be regarded as the birth certificate of the automobile. In July 1886 the newspapers reported on the first public outing of the three-wheeled Benz Patent Motor Car, model no. 1. The first stationary gasoline engine developed by Carl Benz was a one-cylinder two-stroke unit which ran for the first time on New Year’s Eve 1879. Benz had so much commercial success with this engine that he was able to devote more time to his dream of creating a lightweight car powered by a gasoline engine, in which the chassis and engine formed a single unit.The major features of the two-seater vehicle, which was completed in 1885, were the compact high-speed single-cylinder four-stroke engine installed horizontally at the rear, the tubular steel frame, the differential and three wire-spoked wheels. The engine output was 0.75 hp (0.55 kW). Details included an automatic intake slide, a controlled exhaust valve, high-voltage electrical vibrator ignition with spark plug, and water/thermo siphon evaporation cooling.

Christopher Sholes inventor of Typewritter

Christopher Latham Sholes(1819-1890) has been called the "Father of the Typewriter." Although he did not invent it, he did develop the first practical commercial machine. Sholes also developed the Qwerty keyboard that is still in use today. Sholes was born on February 14, 1819, near Mooresburg Pennsylvania. On his mother's side, his ancestry could be traced back to John and Priscilla Alden, the famous Pilgrims. His paternal grandfather had commanded a gunboat during the Revolutionary War. Sholes' father, Orrin, served in the War of 1812 and was rewarded for his service with a gift of land in Pennsylvania. In 1823, when Sholes was four, Orrin moved his family to Danville, Pennsylvania, were he ultimately apprenticed all four of his sons to become printers. Typewriter by Christopher Sholes A typewriter is a hand-operated mechanical device with which on typing keys can produce printed characters on paper. There are different types of typewriters, including mechanical typewriters, electric typewriters and electronic typewriters. With the advent of personal computers and laptops, typewriters are rarely used anymore, although the QWERTY keyboard layout, which was designed for typewriters, is still used in most devices. Why it is one of the greatest invention it gave people new opportunities to communicate with each other more effectively than what was previously possible with traditional pen and ink handwriting. Writers with stigmatized identities such as blindness, gender, or mental disabilities were masked and neutralized through the typewriter’s universal interface, making opportunities for jobs, school, and other occupations more obtainable for more people. The invention of the typewriter had a profound impact on expanding the opportunities of communication for those whose voice and social network were previously constrained. These new opportunities helped these populations in mobilizing upward in society in ways that weren’t possible before.Typewriters also provided better opportunities to communicate more effectively for the blind population outside of obtaining better jobs.
