The Electric Eraser: A Surprisingly Useful Tool

I am fascinated by the enthusiasm of the early twentieth century for the collapse of daily things. Manual tools, scripts, Hot combs– They are clearly benefiting from a tremor electrification. But the eraser? What was a big problem in the modest eraser that it needed lighting?

There are a number of things, it turns out. According to Herman Lukovsky in 1935 Patent Patent application For an erasing device, “peach -handed rubber rubber and covers more space than it may be required.” I, there is rubbing, as it was. He said that Lukovsky’s conical electrical axis can deal better with fine details.

Electric eraser can also be time. In the days before the drawing with the help of the computer, the ease of deletion and retreat, the document may be manually erased with an accurate process.

Looking at Roscoe C. Sloane and John M. Montz suggested in their 1930 book Topical drawing elements. To make a correction on a map, this Civil engineering Professors in Ohio State University We recommend the following steps:

1. With a soft and sharp knife, choose the ink from paper. This can be done without distorting the surface.
2. Put a difficult smooth surface, like a [drafting] Triangle, under erasing before starting rubbing.
3. When all ink is practically removed with a knife, rub with a pencil.

It was not erased for weak heart!

A brief history of the eraser

Where did its path start? British scientist Joseph Prestle It is celebrated to discover oxygen and not at all celebrate to discover the eraser. Around 1766, while working on it History and the current case of electricityand He found himself forced to draw his illustrations. First, although he had to learn to draw, and because any new artist makes mistakes naturally, he also needed erasure.

In 1766, or nearly, Joseph Prestle discovered natural rubber properties.Pioneer

Unfortunately, there were not many great options to erase at the time. For ink elements, it can use a knife to scrape errors; Breaks or other rough stones can also be used to highlight the page and remove the ink. To erase the pencil, the usual approach was to use a piece of bread or bread crumbs to grind gently Graphite Outside the page. All methods were a problem. Without intense care, it was easy to harm the paper. The use of bread was also chaotic, and as the writer and artist John Roskin said, he was totally good bread.

As the story says, Bristley accidentally grabbed a piece of Caoutchouc, or natural rubber, instead of bread and discovered that he could erase his mistakes.

Peristley may discover this feature of rubber, however Edward NairneInventor, optical specialist, and scientific science maker, marketed it for sale. For three shillings (about one day of the wages of a skilled merchant), you can buy a half -inch cube (1.27 cm) of the material. Bristle Nerne acknowledged the introduction to the 1770 tutorial on how to draw, A familiar introduction to the theory and practice of perspectiveand Noting that Caoutchouc is perfectly adapted with the purpose of eliminating paper with black pencil marks. By the late 1970s, Caoutchouc cubes were generally known as rubber or disputed.

Natural rubber may be useful for erasing, but it is not necessarily an element you want to sit on your office. It is very sensitive to temperature, becomes cruel and fragile in the cold, fine and gum in the temperature. Over time, it definitely decomposes. And worse than all, becomes stink.

What was a big problem in the modest eraser that it needed lighting?

Fortunately, there were many other people looking for ways to improve natural rubber, and in 1839 Charles Judier The corridor process developed. By adding Sulfur To the natural rubber and then heating it, Godyear discovered how the rubber stabilizes in a fixed state Polymers. In 1844 Goodyear patent A process to create a rubber fabric. He continued to make rubber shoes and other products. (the Tire Company This was founded by the two brothers Charles and Frank Sibering after several decades.) Judyer, unfortunately, died busty, but we got a better eraser than discovering it.

Who really invented an electric eraser?

Albert Dreaml, who opened it A liquidated company In 1932, he often gets a balance of invention for electrical eraser, but if this is true, I cannot find a specific guide. Of more than 50 American patents kept by DREMEL, there is nothing for electric eraser. In fact, other inventors may have a better claim, such as Homer C. Koi, who was patented by electrification Automatic eraser In 1927, or Ola S. Bougherode, who was patented to Electrical eraser In 1906.

Dregl Moto-Tool, which was presented in 1935, came with a range of switch bits. One copy can be used as electric eraser.Dreamlil

In 1935, Dreaml came out with Moto toolsThe first high -speed rotor in the world that contained parts of switching for sanding, engraving, playground, and sharpening. One -copy Moto-Tool was sold as electric eras, although it was more like a hammer than a pencil.

Regardless of those who invented the device, the electric motors engines were definitely on the market by 1929. Some of the oldest adopters were librarians, specifically those who kept and had to modernize the card catalog frequently. Margaret Man, Professor of Participation of Library Science at the University of Michigan, included an electric eraser as recommended equipment in her book 1930 Introduction to indexing and classifying books. A round round eraser is described by a round round installed on a tool driven by the engine similar to dentist training. The eraser can remove the typewriter and print the catalog cards without leaving an approximate appearance. By 1937, electrical erasure discussions were part of the library science curriculum in Columbia University. The prevailing electrical sequins were.

To erase the pencil, the usual approach was to use a piece of bread to gently grind the graphite from the page.

In 1930, Charles Broning Public Cashallog had six pages of erasure and accessories, with two pages for the company’s electrical wiping machine. Bruning, which specializes in engineering engineer, drafting, and survey, also presented a variety of unintended eraser products, including steel seizures (also known as desktop knives), eraser shields (used to isolate the area to be erased), and anchor to the pen pen.

the Lauren Manufacturing Company Late arrived at Electric Eraser, where she presented the first such product in 1953. Holding in the hand like a pen or pencil, Presto Electric Eraser is vibrated to highlight a small area in need of correction. The company floats on the Presto brand in 1962, at a time Presto Model 80 [shown at top] It was produced. This particular unit was used by officers workers in New York Insurance Company It now includes in Smithsonian Cooper Hiite.

Creativity of the eraser

When I was older, my father kept electric eras next to the drafting table. I liked to play with her, but it wasn’t that until I started searching for this article that I realized that I was using it all wrong. The positives define that the cylindrical rubber is supposed to form a point for erasing fine lines.

Almost today, all painters, library secretaries and office workers are digital, but some visual artists are still using electric wipes. One of them is an artist and a teacher Daril tankFrom a specialist in pencil drawings. I watched many wonderfully wonderful Videos Compare different models of electric erasure. Seeing the tank used its favorite electricity eraser to create a texture on clothes or movement in the hair that made me realize that the drawing is not just an added process. Sometimes what is removed is what the difference happens.

Suzan Bedmont CountryAnd he is an architect and professor at the Center for Architecture in Washington-Alexandria in Virginia Tech, he thought a lot about erasure. She sponsored the exhibition “Fantasy Tools: Drawing and Technologies from the Eighteenth to the Present” in National Building Museum In 2005 he composed the accompanying book of the same title. Piedmont-Palladino describes the architectural design as a long process of doing, retreating, restoring, and identifying ideas that can remain and must go.

Piedmont-Palladino is written with the love of a pasty past, as this design process has been captured in the building’s plans. When the architect was manually, the same paper became a record of distress, showing the place where it was scraped, erased and redrawn. You can see uncertainty points and decisive points. But today, when almost all architectural drawing is on a computer, users are deleted instead of wiping. With some key strikes, the object can disappear, move to another spot, or miraculously appear from the trash. The design process is no longer engraved on the page.

Of course, the pencil, the eraser (electrical or not), and the whole computer are just tools for the transmission and perception of ideas. The tools of any age of society in ways that are not always clear until the new tools to replace them come. It was necessary to invent the pencil and the eraser, and it was up to historians to ensure that they were not forgotten.
