The history of paper clips
At the end of July 1904 on Moscow from the south-east loomed large black cloud from which hung a huge trunk.One of the firemen took him by the smoke and rushed to extinguish the fire.But the people and the horses were scattered and broken fire wagons.Blown up hanging around the cow, then "ascended to heaven" police, but soon, stripped and beaten by hail, swung down to the ground.It was lifted into the air train shed, which is thrown to the side by 40 meters.Being in the booth lineman alive.The culprit of all these "tricks" - the tornado.He is capable of much, and they caught up items often fall to the ground away from the place of its passing, and sometimes under a clear sky."Fly" people, animals, inanimate objects.
One cranky strong vortex far out to sea on a sandbank was moved the whole house.And where the house stood before the mountain was bivalve shell mollusks, thrown from this very shallow.Once the inhabitants of one of the towns in Africa is very surprised when, together with a rain shower sprin
invention appears when it has an urgent need.When the clip was the need?After all, they treated as before without it.Yes, but the number of business papers with increased development of the industry.And it was necessary to fasten them.It's hard to say who guessed adapted for this purpose, a piece of bent wire.In any case, one of the first was the Norwegian Johann Waller, who has submitted an application in 1899 to "paleoskrepku".It is remarkably similar to the modern, but had a couple of pranks anymore.The design has been successful, but something happened that happened more than once in the history of inventions.Clip started to improve, however, new developments in many respects, not only inferior to the original, but also highlights its advantages.In 1902, the German E. Libing offered a collection of new clips, but only one - with playful curls - undertook to produce firm.So, for fun.
Why clip Waller wanted to improve?What are its weaknesses?Their two.Firstly, it is wrinkled sheets.Wire pressed on paper too small area.Then we come up with a variety of delicate patterns to distribute the load over a larger area.Second, the clip quickly broke down.Then to eekontsam steel welded special bow, solder the ends of the wire.But new operation was added, and the mass production of this increases the cost of production.So that the inventors did not remain idle.And their imagination fails.There were clips in the form of a ring, in which we carry keys, paper clips, cast in plastic.When so many securities, helps to clip the tongue, where you can put down any designation, and if provided in a paper clip hook, the paper can not put on the table, and hung on a nail.
Now let's talk about the button.Its purpose - to attach the paper to the board.It's like a "stud for the paper."Indeed, one of the first keys (it offered the Germans X. A. Eichmann and Kirsten in 1879) looked just like a nail for furniture upholstery.It is an island with a hat from a thin metal plate, which he put under the shaybochki, then crimped cap.Two years have passed, and there was the familiar design - tin circle with the cut down in the center and bent perpendicular to the edge.It was developed by V. Matz, a resident of Berlin.First, the buttons do by hand - cut down a chisel, also offered to produce them from the metal bar on a lathe.But such a proposal is unlikely anyone ever realized too expensive to become a button.But manufactured components of a button - the tip is inserted into the opening of the cap, and then solidified.
But let us decide what are the requirements of a button.It should be easy to penetrate into the wood tightly to sit in the board and reliably fix a sheet of paper, is easily removed from the board, and finally, on its own button must be sufficiently robust and long to serve.To meet all these requirements, created dozens of interesting designs.Here are just some of them.Button, which is provided with a tip indent, best kept in the board.Button with an elongated spring-loaded (curved center) presses the paper hat good - in the center, where the tip and on the edges of the cap.Button with upturned edges easily pulled out of the board.The same purpose is served by a button with a hook and a second hat.There are unexpected solutions.For example, "neprotykayuschaya" vacuum button, which is a rubber cap, a suction cup, which sticks out from the plate-clamp.
