Zhu Youzhen is really a little excited these days.
Since Li Yusheng, Liu Bing and others came to the Palace of Qianqing, three important civilian technologies are now in front of her. The spinning wheel has been handed over to Liu Xianzhi, and the self-ringing bell has been handed over to Tang Ruowang.
But he still needs to do it himself on rubber tires.
In the history of later generations, Zhu Youjian rode bicycles to and from get off work. He has a basic understanding of the structure of bicycles. Rubber tires are generally divided into inner and outer layers. The outer tires are hard and thick, acting as a protective layer for the inner tube. The valve on the inner tube is not difficult. Production, but how to make an inner tube with no gaps really stumped him.
In later generations, this is a technique in pediatrics, and it will not even be recorded in books. He has no information to learn from now.
Fortunately, Li Yusheng sold a huge amount of rubber, and there were enough materials for the craftsmen to experiment. Zhu Youjian did not set a timetable for the craftsmen.
The first to hear the good news was the Academy of Sciences. According to the drawings, Tang Ruowang fully understood the production process of the tolling bell. Because he was proficient in Chinese, he directly remade a production drawing in Chinese.
"It's too delicate." Looking at the production drawings of Tang Ruowang, the old craftsman felt incredible. "Your Majesty, according to the drawings, maybe we can produce the bells."
"What is maybe?" Zhu Youzhen was puzzled, "Can you produce?"
"Your Majesty, these steel bars and these gears are so exquisite. It is difficult for us to produce parts of the same size." After these craftsmen entered the R&D Institute, everyone’s skills and craftsmanship were purchased by Zhu Youjian. The craftsmanship belongs to the R&D Institute, not the individual. Now everyone is working together. However, with their craftsmanship, it is estimated that such exquisite parts may not be able to be manufactured. A large number of repeated productions and consistent specifications and sizes are even more difficult.
It turned out to be a product specification problem. Zhu Youjian can only find the answer from later generations. "Mold, you first produce a set of molds according to the size of each part. Since the mold is fixed, the produced parts will of course be of the same size. Consistent."
"Your Majesty, Caomin understands that if the corresponding mold can be produced, when the factory is established in the future, it can be divided into multiple production units, and each production unit is responsible for the same main parts, and then assembly line production can be realized." Assembly line production is not only In the Daming Firearms Bureau, it is also commonly used in various places of the Royal Affairs Department, and these craftsmen have long been familiar with it.
The craftsmen were already looking forward to their bonuses, but Zhu Youzhen returned to the Palace of the Qing Dynasty. The first thing he did when he came back was to see Liu Xianzhi.
In the warm pavilion in the last row of the Qianqing Palace, Liu Yuzhi is spinning, and the two court ladies use their fingers to help separate the cotton. The cotton will become more even after passing through their hands. The waiter from Zhu Youjian just looks right. When a cotton thread broke, a court lady was hurriedly connecting the wires. Liu Yuzhi stopped the spinning machine and heard a sound of footsteps.
"Your Majesty..." Liu Xianzhi crawled in front of Zhu Youjian.
"Miss Liu doesn't need to be polite, she is in the palace every day," Zhu Youjian motioned to Liu Xianzhi to get up by herself, "How about, is there any progress on the spinning machine?"
"Your Majesty, it's still not possible." Liu Xianzhi shook his head from side to side, throwing the sweat from his face far away, "Because there are too many spindles, there are imaginations of being mixed together, and the problem of broken cotton threads can't be solved."
"Oh, a great invention, of course it is not so easy." Zhu Youjian estimated that it was the same. The two court ladies hurriedly assisted Liu Xianzhi, that is, three people are spinning, not one person, and it is still away from the Jenny spinning machine. It’s a long way off, "Miss Liu, try again, I'll be watching."
"Yes, Your Majesty." Liu Xianzhi took a seat, just as the maid had already connected the broken cotton thread, Liu Xianzhi carefully spun it.
After a while, the two cotton threads in the middle were tangled together. Liu Yuzhi had to stop and let the maid untie the two cotton threads, "Your Majesty, look... hey..."
This is indeed a problem. If the problem of mixing several cotton yarns cannot be solved, the spinning machine will not be successful. Zhu Youjian went around the spinning machine and found that Liu Xianzhi had fixed the wooden frame for spinning cotton in the spinning machine. The front part of the yarn machine, so that the distance of the cotton thread in the air, is already very short, but the spindle is under the rear part of the spinning machine, and the two are not on the same horizontal line.
"Miss Liu, raise the rails that hold the spindles upwards so that they are at the same level. In addition, add a baffle to the front of the wooden box containing the cooked cotton."
"Your Majesty, move the spindle up to shorten the length of the cotton thread outside, but if you add a baffle in front of the wooden box, can the cooked cotton run forward under the pull of the cotton yarn?" Miss Liu has already moved from the square wood. Stand up on the stool and put it on Zhu Youjian's left hand.
"On the front baffle, dig eight small holes as thick as your thumb, and then let each cotton thread come out of the small hole." Because there is a certain distance between each small hole, Zhu Youjian believes that the cotton thread Will not get mixed up.
"Your Majesty, the Caomin understands that there will be a fixed interval between the cotton threads, and they will never get mixed up again," Liu Yuzhi was even more happy than Columbus discovered the American continent. "Your Majesty, when the cotton thread comes out of the small hole, It is equivalent to passing it through the palm of the hand, and the cotton thread will be thin and even."
"Well, you can continue experimenting. Actually, I don't know how big this small hole is. You can ask them to make a few more pieces, and then see how big the small hole is most suitable."
"Yes, Your Majesty," Liu Yuzhi sent Zhu Youjian away, and turned to the little eunuch, "Quickly, according to your Majesty's instructions, make a few of these baffles. As for the size of the holes... From little to thumb One piece, the distance between each hole should be equal, and the edge of the hole should be wrapped with silk cloth to prevent the cotton yarn from being scraped."
"Yes, Miss Liu, let's do it right away." The two little eunuchs ran away.
After the little eunuch's work day and night, the next morning, five baffles that fully met Liu Xianzhi's requirements were completed. Miss Liu quickly ate breakfast and started her great invention dream again.
This time, Miss Liu found that the problem of mixing the cotton thread was solved, and the cotton thread spun out was similar to her imagination, thinner and more even than before, but the problem of yarn breakage still exists.
Liu Xianzhi stopped the spinning wheel, her small mouth pouted enough to hold a spindle, "Why can I solve some problems every time my Majesty comes, but I can't solve anything? Am I too stupid?"
The court ladies and eunuchs just giggled on one side, and they didn't dare to disturb the obsessed lady.
"What are you laughing at?" Liu Yuzhi wanted to find someone to fight and completely get rid of the evil spirit in his heart.
A court lady bit her lip and said: "Miss Liu, how can you compare to your majesty? Your majesty is the emperor, and the power of heaven is unpredictable. Our majesty is omnipotent."
"Anything?" Liu Yuzhi thoughtfully, she said silently in her heart: Did your majesty know about the Jenny spinning machine? Did he deliberately reveal only a little bit at a time? What is this for
The court ladies and eunuchs looked at the dazed Miss Liu, only shook their heads and sighed.
It happened that Zhu Youjian came to see Liu Yuzhi’s spinning wheel. Liu Yuzhi Mingming saw Zhu Youjian, but she was sitting on the square wooden bench, propped up her right arm to support Xiangji, and did not even look at Zhu Youjian. .
Zhu Youjian felt strange. Liu Yuzhi used to be full of enthusiasm on the spinning wheel. Why was he in a daze today? She deliberately raised her face and drank to the eunuchs and court ladies: "Which one of you made Miss Liu upset?"
"Your Majesty..." The eunuchs and palace ladies were so scared that they knelt down in front of Zhu Youjian, "We didn't make Miss Liu angry."
"Oh, get up, then!" Zhu Youjian saw Liu Yuzhi looking indifferent, and asked: "What's the matter, Miss Liu?"
"It's all you!" Liu Yuzhi didn't look back, and continued to sit on the square wooden stool, and did not give Zhu You the luggage.
"Bold! Dare to speak to your majesty like this?" Zhang Yixian shouted.
Zhu Youzhen reached out his hand to stop Zhang Yixian, "What's wrong with me?" He was really puzzled, "Isn't the spinning machine researched yet?"
"Your Majesty," Liu Yuzhi was even more annoyed when she said about the spinning machine, "Your Majesty knew that Jenny Spinning Machine, why didn't you tell the girl? Let the girl take pains?"
"I will make Jenny spinning machines? Who said that?" Zhu Youjian turned his gaze to the eunuch maid beside Liu Xianzhi, "Who said that?"
"Your Majesty, there are no servants, how can the servants dare to talk too much?"
"Your Majesty, who said it," Liu Yuzhi finally got up from the square wooden bench, her face full of anger: "Your Majesty knows the manufacturing method of Jenny's spinning machine, why not say it all at once?"
"Then how did Miss Liu know that I would make a Jenny spinning machine?"
Liu Xianzhi asked, "Isn't your majesty omnipotent?"
"Anything?" Zhu Youjian smiled slightly, "Does this kind of rumors also believe Miss Liu?"
"But... But every time your Majesty comes over, he will improve the spinning machine. What's going on...?"
"Because of this?" Zhu Youjian laughed. "Every time I watch Miss Liu spinning, I can naturally see some famous people-if I could make Jenny spinning machines, I would have opened a spinning factory near the capital. Will you wait until now?"
"This... Does your majesty really know how to spin a Jenny?" Liu Yuzhi's eyes widened and looked innocent. "Men's daughter... How do you feel that your majesty will find the problem..."
"That's because you are only focusing on spinning, and naturally you can't see how to improve," Zhu Youjian said with a light smile: "I don't want to go spinning, or how can I find the problem—what is the problem now? ?"
Liu Xianzhi obediently returned to the square wooden stool and replied while spinning, "It's still the problem of broken yarn."
As Liu Xianzhi said, she spun for a while, just as she was about to speed up, there really was a yarn breakage problem again. This time Zhu Youzhen really had nothing to do, so he had to look at Liu Xianzhi with a wry smile, "I didn't look Where is the problem."
"Your Majesty," Zhang Yixian whispered to Zhu Youjian, "Maybe it will be better if you change to a skilled spinner."
Zhu Youjian understands that although Ms. Liu can spin, she was born in a wealthy family. She will never spin for a long time. She is not skilled, and there will be yarn breakage problems. "Yi Xian, look for two from outside. The skilled spinners come here."
After the two female spinning workers entered the palace, the yarn broke when they opened. About half a day later, the problem of yarn breaking was finally solved. They did not modify the spinning machine, but changed the strength with dexterous fingers.
"Your Majesty, this is Jenny's spinning machine?" Liu Yuzhi was full of joy. For whatever reason, her anticipating spinning machine finally succeeded.
"It should be a success," Zhu Youzhen was also secretly delighted, "As for the improvement in the future, it is up to you."
"Well," Liu Xianzhi looked at Zhu Youjian, her eyes blurred, "Your Majesty..."
"Why, homesick?" Zhu Youzhen laughed. "I have an appointment with your father for one month. I didn't expect Miss Liu to be too smart. It took less than half a month to complete the spinning machine. "
Liu Xianzhi's big eyes suddenly lost their brilliance, and she faltered and said: "Your Majesty... Since I have an appointment with my father, it is not time now, Minnv wants to... think... stay in the capital for a while."
"Stay in the capital? Miss Liu, haven't you already succeeded?"
"Your Majesty, the folk girl... The folk girl is reluctant to leave the capital... Didn't your majesty say that there is still a spinning machine that can install 15 spindles? If the folk girl goes back, once there is a problem with the spinning machine, there is really no way to guide the folk girl People." Liu Yuzhi finally found a reason to stay.
