The twist drill: John Wilson invented the boring machine in 1774, but his drill was a cutting bar. Steven A. Worse invented the drill bit in 1861. it cuts a clean hole and lifts debris up and out as it turns, Morse manufactured his bit and sold it to various industries and in several countries. Its what we think when we imagine a drill, and they are used in large and small construction projects alike. Repeating rifle: The rifle had evolved from the barques and musket result in increased accuracy. but was slow loading. Benjamin Tyler Henry invented the lever action repeating rifle in 1860 after spending years working as a gunsmith. it could rapidly fire 17 powerful rounds at close range, it rose to fame during civil war as a rare but novel item that soldiers though would help save their life, then as the iconic western rifle following the war.

The 1840s were a period of political and economic turmoil that led to a relatively stable decade following. The ironing board was invented in 1858 as home ironing became more common. It provides Portability to be set up mostly anywhere, And it is shaped to make it easier to iron the hard parts of clothes. The board was improved, and improved irons, especially the electric iron, increased demand for them. They introduced another source of time savings into the common family.

The industrial revolution was inspiring inventors to investigate how to improve age-old processes. Hamilton Smith Invented the washing machine in 1858 to bring benefits of technology into the home. washing machines automatically and efficiently clean clothes and drastically reduce the time and labor involved. Improved machines were advertised and by the 1930s a million were being sold every year. Housewives gained a lot of free time, which contributed to the rise of the Restaurant industry.

The Safety Elevator: Ancient civilizations used simple machines to create elevators but innovation stalled out in the 1800s. Elisha Otis invented the Safety Elevator in 1852 while looking for a better, safer way to lift scrap wood in a factory. The Safety Mechanism stops the elevator from plummeting into the ground if the cable snaps. Otis implemented a dramatic market in demonstration of his elevator to attract interest and promote sales. Otis elevator are installed in sky scrapers all over the world.

Pin-Tumbler Locks: The outbreak of socialist revolutions across Europe in 1848 drove immigration of America. Linus Yale jr Invented the Pin tumbler lock in 1843 to serve the growing bank industry. Pin tumbler locks are difficult to pick and provide good security, As well as easy Re-keying. Linus Yale jr. used advertising to promote the benefits of his locks and expose the weakness of competeing. Pin tumbler locks are one of the most common kinds of locks today.

The Erie canal stimulated grain from the mid west to the eastern coast. Joseph Dart was an entrepreneur who spotted oppurtunity to invent the grain elevator in 1842. grain elevators quickly remove grain from ships or other transports store it, and dispense it. Darts engineer, Dunbar built many elevators in buffalo, the US, and overseas. Their invention enabled the US to become the worlds leading producer of grains.

Ancient cultures used rubber for basic waterproofing and games. Charles Goodyear invented vulcanized rubber by accident. Vulcanized rubber improves Rubber’s durability, prevents it from melting and breaking, and requires heat. Goodyear died practically bankrupt, but a rubber company was founded a generation later and named in his honor. Goodyear among top 10 rubber companies, and industry relies heavily on rubber seals. thats my assignment!

The US company became effective in 1789. Joseph Henry, born 2 years earlier, became one of the modern fathers of Electromagnetisim. The electrical relay uses an electromagnet to remotely drive a mechanical or electrical switch. The relay spread because it was vital to the operation of the telegraph, acting as a signal amplifier. [ It ”Relayed” the signal.] It evolved becoming a fundamental in numerous industries, especially the power industry.

Solar Compass: Surveying is an ancient profession dedicated to accurately determining property boundaries. William Austin Burt Devised the Solar Compass to remove interference effects from local magnetic fields and develop accurate readings. The Solar Compass was a complex device that did not suffer from magnetic field interference, it became the US Governments standard surveying to after its patent expired, Michigan became leading producer of iron as a result of Burt’s invention.

The development of scale technology began improving during the middle ages. Thaddeus Fairbanks invented the platform scale in 1830 while trying to figure out how to weigh large loads of objects without any encounter weights or cranes Fairbanks scales began to be sold throughout the world by the mid-1800s, the scales are still in use today as componets in numerous industries, the scale makes it easier to weigh large loads and can save time. this scale is very useful in the world and is a great invention. this invention by Thaddeus Fairbanks is a great great invention and if it wasn’t invented maybe another scale would’ve.
