History of hardware

Craftsmen and builders use hardware hand tools to perform manual tasks such as felling, chiselling, sawing, filing, and blacksmithing. While the date of the earliest tools is unknown, researchers have found devices in northern Kenya that could be around 2.6 million years old. Some of the most popular tools today include chainsaws, wrenches, and circular saws, all of which have their own unique history.



Chainsaw History of hardware

Several major manufacturers of chainsaws claim to have invented them first.

For example, it is believed by some that Californian inventor Muir was the first to put a chain on a logging blade. But Muir's invention weighed hundreds of pounds, required a crane, and was not a commercial or practical success.

In 1926, German mechanical engineer Andreas Stihl applied for a patent for an "electric chain saw". In 1929, he also patented the first gasoline-powered chain, which he called the "felling machine". This is the first successful patent for a hand-held mobile chainsaw designed for cutting wood. Andreas Stihl is most often considered the inventor of the mobile and electric chain saw.

Finally, in 1972, Atom Industries started making chainsaws. They were the first chainsaw company in the world to offer a full range of saws with patented electronic ignition and patented self-cleaning turbocharged air cleaners.



circular saw History of hardware

Large Circular Saw, a circular metal circular saw that cuts through spinning, can be found at lumber mills. Samuel Miller invented the circular saw in 1777, and in 1813 Shacklebolt's sister Tabitha Babbit invented the first circular saw used in a sawmill.

Babbitt was working at a spinning mill in the Shaker community of Harvard, Massachusetts, when she decided to improve her double deck saw for lumber production. Babbitt also invented an improved nail clipper, a new method for making false teeth, and an improved spinning wheel.



Bourdon tube pressure gauge History of hardware

The Bourdon tube pressure gauge was patented in France in 1849 by Eugène Bourdon. It remains one of the most common instruments used to measure the pressure of liquids and gases, including steam, water, and air, up to 100,000 psi.

Borden also founded the Borden Sedeme Company to manufacture his inventions. Edward Ashcroft later acquired patent rights in the United States in 1852. It was Ashcroft who played an important role in the widespread use of steam power in America. He renamed the Borden gauge the Ashcroft gauge.



Pliers, pliers and pliers History of hardware

The gluer is a hand tool used primarily for holding and gripping objects. Simple glue is an ancient invention, as two sticks were probably the first indeterminate bracket. It appears that bronze rods replaced wooden tongs as early as 3000 BC.

There are also different types of pliers. Round plywood for bending and cutting wire. Diagonal cutting inserts are used to cut wire and small pins where large cutting tools cannot reach. The adjustable spline layer has knurled jaws with an extended hinge hole in one piece so it can rotate in either of two positions to grip objects of different sizes.



key History of hardware

A wrench, also known as a wrench, is a typical hand tool used to tighten bolts and nuts. The tool acts like a lever and has a notch in the mouth for gripping. The wrench is at right angles to the action of the lever and the axle of the bolt or nut. The neck of some keys can be tightened to better accommodate various items that need to be turned.

Solimon Merrick patented the first wrench in 1835. In 1870, steamboat fireman Daniel S. Stillson received another patent for a wrench. Stillson is the inventor of the pipe wrench. The story is that he proposed to Walworth, a heating and plumbing company, to design a wrench that could be used to make pipes. He was told to make a prototype and "either unscrew the pipe or break the key". Stillson's prototype successfully flipped the tube. His design was subsequently patented and Woolworths built it. Stillson paid about $80,000 in royalties for his inventions during his lifetime.

Some inventors later came up with their own wrenches. Charles Monkey invented the first monkey wrench around 1858. Robert Owen Jr. invented and patented the ratchet wrench in 1913. NASA/Goddard Space Flight Center (GSFC) engineer John Vranish is credited with the idea of ​​the non-ratchet wrench.
