The story about Lu Ban s invention, the story of what Lu Ban invented

Luban makes umbrellas. The final sentence of this invention was attributed to Lu Ban's wife. In ancient times, rainy days and scorching summers plagued people, and people had to hide under small pavilions and not go out.

There is a legend that Luban built many small pavilions around his neighbors for everyone to use, but still did not allow people to go out freely during the stormy season. Lu Ban's wife then made a lightweight bamboo pavilion with oiled paper in the style of the pavilion her husband had built—an umbrella, of course. His wife said to Luban:

The house you build can't be moved up. My umbrella can take it around and protect it in all seasons. ”

The story of Lu Ban's invention of the ink fountain.

Lu Ban created the ink fountain for carpenters to draw lines, which was inspired by the fact that he saw his mother cut clothes with a powder bag.

When the ink fountain was just ready, Lu Ban had to ask his mother to help him pinch one end of the ink line every time he played the line. Sometimes, when my mother was making clothes or cooking, she had to put it down and rush to help. Be cautious of spring.

One day, Luban's mother said to him, "If you make a small spoon, can't you pinch the ink line instead of me?" Lu Ban listened:

Yes! "He made one very quickly. From then on, a person can also play the ink line.

Until now, carpentry masters still call this little hook "class mother".

1. Another very important tool invented by Lu Ban was the ink fountain used by craftsmen (used to set up construction projects), which may have been inspired by his mother. At that time, his mother was cutting and sewing clothes, and Lu Ban watched all this, and saw that she was using a small powder bag and a thread to print out the shape of the desired cut.

2. Lu Ban transferred this practice to an ink fountain, pinched both ends of it through a thread (a thread soaked in an ink fountain) and put it on top of the material to be made to print the required lines. Initially, Luban and his mother held the ends of the line. Later his mother suggested that he make a small hook to tie to one end of the thread, so as to free her from this chorre and make it possible for one person to do it.

In honor of Luban's mother, the craftsmen still call this ink fountain the mother of the class.

3. Luban deals with wood all day long. He was highly skilled, good at using an axe, and could chop wood into the desired shape in a few strokes. However, it is difficult to cut the wood with thick grain and many knots into the desired shape.

In order to solve this problem, Lu Ban pondered during the day, and thought at night, he first made a thin axe, sharpened it quickly, and cut it much better than before, but it was still not ideal.

4. So, Lu Ban sharpened a small thin axe, which was covered with a piece of iron, so that only a narrow blade was exposed to the axe. This time, Lu Ban didn't cut it. He used the narrow blade to push against the wood.

With a push, the wood pushes down a thin layer of wood chips. After pushing more than a dozen times, the surface of the wood is flat and smooth, much stronger than in the past when cut with an axe. But when this thing is pushed in the hand, it is both stuck and weak.

Lu Ban made another wooden seat and put it in it. Planer, and thus was born.
