Inventions generally are meant to solve a problem. Sometimes we didn't even realize some problems we had and we don’t see them. The inventions make our lives easier by providing a Better Way to do something or simply give us an option we didn't know. In fact, successful inventions and innovations provide a solution to a problem. One of the clear examples of these, is the wrench, a simple applicable mechanical tool.
Have a look around; You can see a variety of small and large devices and machines whose parts and components are connected to each other using bolts and nuts. From a giant bolt in a steel ship's structure to the very fine screws used in Swiss watches, they all need to be opened and closed for construction, maintenance. For each of these tasks, special tools are designed to lift them. Just look at your wrench box or bag to see some of these tools that are needed for normal tasks. For example, imagine your car tire is punctured. The first step is to loosen the tire’s nuts and then replace the tires. Then, you need to put the nuts back in place and fasten them tightly. But how can these various beads be opened and closed?
The answer is simple. Selecting a suitable wrench and open and close the nuts based on the physical principles of the lever. But, do you know how and when the wrench was invented? Who is the original inventor of this practical tool and how has been its evolution over the years?
The wrench, also known as the "Spanner", is generally a hand tool for fastening bolts and nuts or keep them from turning. which is now produced in a variety of models, including open-end wrench, box-end wrench, flex-head socket wrench
Salutes wrench, adjustable wrench, and even, electric types of the wrench.
The original inventor of mechanical wrenches was Solymon Merrick, who in 1835 filed the first patent in this field.
Perhaps the most significant advancement in mechanical wrenches is the extraordinary design of Daniel C. Stillson. He, who was in charge of the boiler, while working on the steamships, created a mental design of a new wrench. Stilson believed in his idea and share and introduce the idea with the heating and plumbing company Walworth. At first glance, his proposed wrench looked a bit strange, and for this reason, the company's managers preferred to make a prototype of it before making any decision. The result was amazing and the wrench could work well. The invention was registered with the US Patent and Trademark Office in 1869 and resulted in the grant of a patent number "US 95744" to Walworth. Stilson received an $ 80,000 reward for his creative idea, and his invention became known as the Stilson Pipe Wrench.
Half a century later, in 1913, Robert Owen came up with the idea of double wrenches (with two different shape ends), which became the introduction to the design and production of adjustable wrenches with multiple series. A Swedish inventor named Johan Petter Johansson was also working on the idea of adjustable wrenches. He received his first patent in 1888 for an adjustable pipe wrench.
But one of the most interesting inventors active in the development of the wrench is a black man named Jack Johnson. He was a provocative black boxer who owed most of his fame to his athleticism and violation of social norms. In 1903, Johnson won the World Heavyweight Boxing Championship. But this title did not satisfy him. He wanted to be a real-world champion, so he caused a great deal of controversy by repeatedly defeating white boxers and making fun of them in the boxing ring. Attempting to marry a white girl and violating against her being sued by the federal government and he escaped to Europe. Johnson lived in Spain until the mid-1920s when he returned to the United States and was sent to federal prison. This is where the controversial side of this athlete's life came into play. He was imprisoned with the problem of tightening some parts of M.
We are one of the most interesting inventors active in the development of the wrench, a person named Jack Johnson. He was a controversial black boxer who owed most of his fame to his athleticism and violation of social norms. In 1903, Johnson won the World Heavyweight Boxing Championship. But this title did not satisfy him. He wanted to be a real-world champion, so he caused a great deal of controversy by repeatedly defeating white boxers and making fun of them in the boxing ring.
Attempting to marry a white girl and violating certain laws led to her being prosecuted by the federal government and fleeing to Europe. Johnson lived in Spain until the mid-1920s when he returned to the United States and was sent to federal prison. This is where the controversial side of this athlete's life came into play. In prison, he had trouble tightening some parts and designed a new wrench to fix them. Jack Johnson's innovative wrench was registered in 1922 and resulted in a patent certificate number "US 1413121". Johnson was no longer a prison boxer, he was an inventor whose tumultuous life could inspire many inventors and innovators.
It is interesting to note that some people mistakenly attribute the name Monkey Wrench to Jack Johnson, which refers to a kind of racial insult to this inventor. However, there is no connection between this name and Johnson's invention, and as emphasized in the previous lines, the monkey wrench was invented by Charles Monkey. In other words, the name of this wrench is derived from a misspelling associated with its inventor!
