- Welcome to Tech info. In this video we will review the top 10 inventions in 1850’s that had a significant impact on humans by improving communication, increasing productivity, and making life more comfortable and enjoyable. So, let’s get started.
1. Elevator: Elisha Otis invented the safety elevator in 1852, which made tall buildings practical and paved the way for skyscrapers. Prior to the safety elevator, buildings could not be constructed higher than a few stories because of safety concerns. The safety elevator used a braking system to prevent the elevator from falling in case of a cable failure, making it safe to transport people and goods to higher floors.
2. Repeating rifle: The repeating rifle was invented in the 1850s and significantly improved the firepower of soldiers in battle. The Spencer and Henry rifles were two of the most popular repeating rifles of the time, allowing soldiers to fire multiple shots before needing to reload. This made them more effective on the battlefield and gave them an advantage over enemies still using single-shot rifle.
3. Sewing machine: The sewing machine was a revolutionary invention in the 1850s, transforming the clothing industry by automating the process of stitching fabric together. The machine could stitch up to 900 stitches per minute, making it possible to produce clothing and textiles more quickly and efficiently than ever before. Isaac Singer and Elias Howe both patented the sewing machine in 1851, with Singer's version being the most successful due to its design and marketing strategies.
4. Telegraph: The Morse code telegraph was invented by Samuel Morse and Alfred Vail in 1837, but it wasn't until the 1850s that it saw widespread adoption. The telegraph allowed for faster communication over long distances, revolutionizing the way people communicated and played a crucial role in the development of modern communication technology. Messages could be sent and received in minutes instead of days or weeks, leading to faster business transactions and improved communication between governments and individuals.
5. Bessemer process: Invented by Henry Bessemer in 1856, the Bessemer process was a method for mass-producing steel, making it a more affordable and versatile material for construction and manufacturing. The process involved blowing air through molten iron to remove impurities, resulting in a high-quality steel that could be produced on a large scale. This innovation led to the rapid expansion of the steel industry and had a significant impact on the development of modern infrastructure and transportation.
6. Fountain pen: The fountain pen, invented in 1856 by Petrache Poenaru, was a major improvement over the previous dip pen, as it could hold ink inside and write continuously without needing to be refilled. This invention made writing easier and more efficient, and the fountain pen soon became a popular writing instrument around the world.
7. Mass-produced matches: In 1855, Johan Edvard Lundström invented the matchstick, which could be mass-produced and was safer to use than previous methods of starting fires. This invention quickly became popular and helped to improve fire safety, especially in homes and businesses.
8. Ice-making machine: Invented by John Gorrie in 1851, the ice-making machine revolutionized the way people preserved food and cooled drinks, leading to the development of the modern refrigerator. The machine used compressed air to cool water, which was then frozen into ice. This innovation made it possible to transport perishable goods over longer distances and allowed people to enjoy cold drinks and food in hot climates.
9. Pneumatic tire: Robert William Thomson invented the first pneumatic tire in 1845, but it wasn't until the 1850s that John Boyd Dunlop improved upon the design, making it practical for bicycles and other vehicles. The pneumatic tire was a significant improvement over solid rubber tires, providing a more comfortable and efficient ride for cyclists and other users.
10. Camera lens: In 1856, Charles Chevalier invented a new type of camera lens that produced sharper and clearer images than previous models. This lens was known as the "achromatic doublet" and it revolutionized the field of photography.
Prior to the achromatic doublet, camera lenses were typically made from a single piece of glass, which caused chromatic aberration - a type of distortion where colors appear to bleed or fringes of color appear around objects. This made it difficult to capture sharp and accurate images. The achromatic doublet, on the other hand, was made up of two pieces of glass that were designed to correct this issue.
