HISTORY OF TECHNOLOGY, TECHNOLOGY, OBJECTS AROUND US
Ball pen. History of invention and production Directory / The history of technology, technology, objects around us A ballpoint pen is a pen that uses a refill (a tube filled with paste-like ink) with a ballpoint pen at the end to write. The channel through which the ink passes is blocked at the end by a small metal ball, which, when writing, rolls along the surface of the paper, wetted with ink from the back. A small gap between the ball and the walls allows it to rotate and leave a mark on the paper as it rolls. These are the cheapest, simplest and therefore the most common pens.
The ink paste used in ballpoint pens is different from the ink used in fountain pens. It is oil-based and thicker, which prevents it from flowing out of the rod. The principle of the pen was patented on October 30, 1888 in the USA by John Loud. In subsequent years, various designs of ballpoint pens were invented and patented: May 3, 1904 - by George Parker, in 1916 - by Van Vechten Reisberg. The modern ballpoint pen was invented by the Hungarian journalist Laszlo Biro (Hungarian Laszlo Jozsef Biro) in 1931 (patented in 1938). In Argentina, where the journalist lived for many years, such pens are called "biromes" after him.
On the morning of October 29, 1945, thousands of people lined up outside the Gimbels department store in New York. People have been waiting for the store to open to buy, as the New York Times ad described, "a wonderful, fantastic pen guaranteed to last two years without refilling." In a day, the department store sold out its entire inventory - 10 pens at $000 each. So on the wave of success, the ballpoint pen entered history, quickly gaining dominance in the writing instrument market. The first step towards this was taken in 1888, when the American inventor John Laud received a patent for an ink pen capable of writing "on rough surfaces such as wood, rough wrapping paper, and others" without clinging to the unevenness of the pen. Actually there was no pen - the ink was applied to the surface by a "marking sphere", which was supported by a number of smaller balls. The design was complex, and, apparently, was never implemented. Over the next 40 years, more than 300 patents were issued for such designs, but all of them had serious flaws: ink leaked out, balls clogged ... In 1938, the journalist Laszlo Biro and his brother George, a chemist who later emigrated to Argentina, were the first to come to the conclusion that a very special ink was required for the ball design: on the one hand, they must dry very quickly on paper, on the other hand, they must not harden on the ball itself, so as not to interfere with its rotation. Laszlo, taking fast-drying printing ink as a model, developed a two-component ink with the help of his brother, consisting of pigment and glycerin, which was quickly absorbed by paper. Thick ink was supplied to the writing unit using a spring-loaded piston and capillary effect. The Biro brothers pen, produced by their Argentine company Eterpen since 1943, turned out to be quite successful. In 1944, the UK bought a license for its production, where these pens under the Biro brand proved to be excellent in the Royal Air Force (fountain pens constantly leaked at height). Eterpen licensed the design to Eversharp and Eberhard Faber, who were preparing to enter the US market with the Eversharp CA (Capillary Action) pen when businessman Milton Reynolds intervened. He realized the market potential of the pen as soon as he saw it on the table during negotiations with the manager of one of the Chicago department stores in 1945. In just four months, with the help of engineer William Hurnergart, he redesigned the pen to circumvent Biro's patents (instead of the capillary effect, he proposed a different solution: a thin reservoir open on one side, from where the paste was fed to the ball under the action of gravity), and put it on sale earlier than the official manufacturer did. In less than a year, 2 million Reynolds Rocket pens were sold. Then competitors entered the market, and the "War of ballpoint pens" began - advertising, patent and price. By 1950, sub-dollar pens flooded the market, and their poor quality even led to the return of "nibs" for a short time. However, in the 1960s, under the onslaught of technological progress, fountain pens still lost their positions, this time for good.
