for turning paper from line to line,and a keyboard on which the letters were arranged in
alphabetical order.
But Sholes had a problem.On his first model,his”ABC”key arrangement caused the keys
to jam when the typist worked quickly.Sholes didn’t know how to keep the keys from sticking,so his solution was to keep the typist from typing too fast.Sholes asked his brother-in-1aw to rearrange the keyboard so that the commonest letters were not so close together and the type bars would come from opposite directions.Thus they would not clash together and jam the machine.The new arrangement was the QWERTY arrangement typists use today.Of course,Sholes claimed that the new arrangement was scientific and would add speed and efficiency.The only efficiency it added was to slow the typist down,since almost any word in the English language required the typist’s fingers to cover more distance on the keyboard.
The advantages of the typewriter outweighed the disadvantages of the keyboard.Typists
memorized the crazy letter arrangement,and the typewriter became a huge success.By the time typists had memorized the new arrangement of letters and built their speed,typewriter
technology had improved,and the keys didn't stick as badly as they had at first.
