Who invented mechanical pencils




















Despite what David Rees claims in Chapter 11 of How to Sharpen Pencils , mechanical pencils do have their place in the pencilverse. Surprisingly, this wonder of pencil technology has actually existed in one form or another for the better part of five centuries. If you take a look at pencil history, you will see that the first image of a pencil ever produced actually looks more like modern mechanical pencils than a wooden pencil.

This image depicts a wooden stock that held replaceable graphite. Vague details exist of a brass propelling pencil that used a spring as early as and an actual early mechanical pencil was found on the wreckage of the HMS Pandora, a ship that sank in First incorporated into the Eagle Automatic, a product of the Eagle Pencil Company, this represents the first true mechanical pencil. As impressive as these mechanical pencils had become, they still had a design flaw when compared to traditional wooden pencils.

Mordan later entered into a business partnership with Gabriel Riddle from to to produce a beautiful, working mechanical pencil. In , Mordan began manufacturing mechanical pencils on his own through "S. Improvements in mechanical pencil design continued throughout the 19 th century with patents registered between and , capped off by the arrival of the spring-loaded mechanical pencil. This design marked the first true mechanical pencil. While a significant advancement, the clutch on the Eagle Automatic had too much give for it to be used for professional drafting.

In , the first twist-feed mechanism arrived, advancing the lead by twisting a screw, which moved a slider down the barrel of the pencil. This style of pencil was the most common type of mechanical pencil at the beginning of the twentieth century. Meanwhile, at the same time in the U. Keeran was creating a similar style pencil that would be the forerunner of most of today's modern pencils. His design was ratchet-based and he patented his lead pencil in with production following soon after.

By the early s, Wahl sold more than 12,, Eversharps. All kinds of custom pencils were available on the market, ranging from classic yellow to ones with odd shapes and bold patterns. From giant pencils to color-changing, the design options are limitless! Even though we're moving toward a digital world, we're not leaving the pencil behind. This stylus is compatible with many iPhones, iPads, and other iOS apps and has the ability to erase mistakes, blend colors, and create fine details.

Modern pencils wouldn't be what they are today without the discovery of an enormous graphite deposit in Borrowdale, England.

As the local myth goes, sometime in the s a fierce storm uprooted a large ash tree. Shepherds tending to their flock nearby noticed a strange black substance clinging to the roots and used the black ash to mark their sheep.

The substance was referred to as: wadd, white lead, black lead, bleiweiss, grafio piombine, bismuth, or plumbago. No matter what it was called, it became a very popular commodity in the country. In fact, by the plumbago was wrapped in paper, string, or twigs and sold all over London. The timing for these pencils couldn't have been better because education was beginning to flourish in the 17th century.

High-class families would send their children to grammar schools where they would learn to read and write. The pencil had a place in the rise of education, leading to the brilliant minds of the future.

I think writing is always a tactile experience and pencils are unique in that aspect. I'm involved in theater and my scripts smell more like graphite and eraser than pen and ink. There is something comfortingly steady and reliable about pencils. It wasn't long before graphite pencils made their way throughout Europe. An entire industry for pencil-making developed throughout the 17th century. In , the first mass-produced pencils were created in Nuremberg, Germany.

At the time, the Industrial Revolution was in full swing, leading to many new jobs and businesses. Even though technology was changing, a classic pencil still had a place in the world. Major inventors like Isaac Newton credited with developing the first reflecting telescope sketched out their designs using graphite pencils.

These drafts served as blueprints for creating groundbreaking works. During the French Revolutionary War, his design was used to replace English graphite since it wasn't as accessible due to France's battle with Britain.

He would then shape his pencils based on the industry where they were being used. For instance, carpenters didn't want round pencils that were going to roll off their workbenches so they were made into a square shape. William Munroe, a cabinet-maker from Massachusetts, is credited with making America's first wood pencils in These pencils were natural and unpainted since they were made with high-quality casings.

Eastern Red Cedar, a popular tree in Tennessee, was used to create the pencils since it didn't cause splinters. Most manufacturers set up shop in Tennessee to be close to the source. To this day, many are still based in the south.

However, pencil manufacturers can be found all over the country. John Thoreau and his son Henry David Thoreau the famed author built their own pencil factory in New Hampshire in the s. This was where they developed a system for making pencils less brittle and greasy by substituting clay for wax. These harder leads or lighter value essentially are often used for sketching and drawing, to get fine lines and subtle shading.

The softer leads or darker values are used to get those rich dark tones, closer to charcoal color. Today, Mechanical pencils are based on three principles. Ratchet-based, screw-based, and clutch based. Ratchet-based pencils have two to three jaws inside a ring, which holds the lead. A button on the end of the pencil controls the jaws.

When the button is pressed at the end of the pencil, the lead moves forward and then separates. When you release the button and the jaws retract, a small rubber inside the tip keeps the lead intact. The lead cannot fall out freely or ride back up.

Screw-based pencils have a screw inside. The screw, when twisted, moves the slider down the barrel of the pencil. Some screw-based mechanism has a lock system. You can push the lead back into the pencil. This type of pencil was popular in the early twentieth century. Clutch-pencils is a variant of a ratchet-based pencil.

They also have two to three jaws. Thicker leads are used in clutch pencils, mostly 2mm to 5. It can hold one lead at a time. The Very Best Pencil for Sketching! A mechanical pencil is a writing tool that is easy to use and can be erased. The use of mechanical pencils has become popular among businesses and students. Some mechanical pencils include an eraser and lead and can be reused.

Mechanical pencil stays the same length with a consistent grip throughout. Mechanical pencils have evolved significantly over the years.

Some models feature liquid graphite nowadays. Samson Mordan and Gabriel Riddle invented the actual mechanical pencil in
