Hongwu Survival Guide

Chapter 263 One foot long and one foot wide
In front of the main hall of the Second Courtyard, just as Zhu Yuan got off the sedan chair, Jin Dahu and Wei also stepped forward to salute together.

After gesturing to the two of them to get up, Zhu Yuan came to the house and sat down. Shangli brought the other two servants to serve tea. Zhu Yuan had already asked Wei Ye: "Is the mattress ready?"

Wei also subconsciously wanted to get up, seeing Zhu Yuan pressed his hand, he sat down again, straightened up and respectfully said: "It's done, but I don't know if it suits the adults. If it's not right, I can change it at any time."

Shang Li, who brought a cup of tea and came forward, bowed and carefully interjected: "Shao Niang is already being moved into the inner house, and she is placed in the innermost courtyard according to the adults' instructions."

There are five courtyards in the middle of the mansion on the lake. Zhu Yuan lives in the fourth courtyard, and there is another courtyard behind, which should belong to the main room of the mansion, but it has been vacant before.Zhu Yuan didn't even think about marrying, so he casually ordered.

After Zhu Yuan picked up the tea and took a sip, Jin Dahu followed suit and said, "My lord, I brought the small scale you ordered, and some ideas about the 'spring escapement' used in making pocket watches. Brother Wei also agreed." I brought a few sets of spring samples, would you like to have a look?"

"Of course I have to see it."

Shangli and the others quickly brought the things up.

What Zhu Yuan looked at first was a stack of manuscript paper, on which were drawn page after page of fine and beautiful mechanical structure diagrams, and, as expected, Jin Dahu's drawings also contained many drawing standards passed down from himself. , such as the most common one, digital labeling.

Just looking at it, without distinguishing the content, Zhu Yuan couldn't help but praise: "Dahu, your painter is good, you can be a gentleman."

Jin Dahu bowed his body: "My lord's praise."

"It's not ridiculous, to be honest," Zhu Yuan said, "I've thought about it for the past two days, Wei Ye, you study at Jinling University first, and when the Industrial University is established, you can become a 'chemistry major' over there Doctor, bring out a class of students. And you, Dahu, it is more than enough to bring a "mechanical major". Although the industrial university will accept other students, it is mainly for you craftsmen's children. You two are the pioneers. Go in, and you will be a patriarch-level figure in the future."

Zhu Yuan mentioned the matter of Wei Ye two days ago, Lao Zhu understood a little bit, and readily approved Wei Ye to study chemistry at Jinling University.Afterwards, Zhu Yuan also thought of more. Whether it is the University of Technology that is advancing or the other two Jinling University and National University, teachers are the biggest problem, so that many emerging majors can only be self-taught.Now, such as Jin Dahu and Wei Ye are simply ready-made, so there is no need to use them for nothing.

It's only been a few days, and when Zhu Yuan talked about the University of Technology and his thoughts on them, the two were both excited and hesitant.

The significance of an industrial university is easy to imagine for two people who are craftsmen and have enough knowledge and understanding.Moreover, the 'doctor' that Zhu Yuan mentioned was the seventh rank.

They have never thought about going from the ninth rank to the seventh rank in a short period of time.

However, another problem is that going to a technical university to be a doctor, even if it is a "doctorate" of the seventh rank, this... seems to affect the future a bit.

Zhu Yuan leaned on the big chair covered with a thick mattress, flipped through a page of the draft, accidentally raised his head, noticed the expectant and tangled expressions of the two, and said with a smile: "I didn't let you always be teachers, the matter of the two workshops You can’t let it go, the main thing is to bring out a group of students in a few years, and, although you have official positions, you are still students in essence, and you can go further in the future by learning more things.”

When Zhu Yuan said that, the two looked at each other, and without hesitation, they got up and bowed to Zhu Yuan at the same time: "Thank you for your support."

"Get up."

Zhu Yuan waved his hand, turned back to the artwork in front of him, did not speak for a while, and admired it seriously.

A few days ago, I went to the watch engraving workshop and proposed the idea of ​​making a pocket watch. Zhu Yuan only remembered the term "hairspring escapement" without any specific concept at all. Unexpectedly, in just a few days, Jin Dahu took out the Several sets of plans.

The core is to use spring filaments of different shapes to make mechanisms to realize the reciprocating movement of the escapement that can only be achieved by swinging the ball before.

After Zhu Yuan finished reading, he turned to the three samples of 'hairspring escapement' sent by Escort Jin. They were all very small, but not small enough to fit into a pocket watch. The smallest one was the size of a palm.

Seeing Zhu Yuan picking it up, Jin Dahu explained: "Master, the size can still be compressed, this is for the convenience of adults to appreciate."

"good."

As Zhu Yuan said, he skillfully found the mechanism and turned it on, and the escapement system in front of him immediately started to "click, click".

Tried the other two, same thing.

After fiddling with all three samples, Zhu Yuan put down the escapement system with a ring-shaped spring filament in his hand, and said, "Do you know what is the key to the hairspring escapement?"

Jin Dahu nodded: "Without the pendulum, there will be no 'isochronism' that the adults said. What I want to study is how to make this 'hairspring escapement' have an effect similar to 'isochronism'. Only in this way can the pocket watch be made accurately."

"That's right," Zhu Yuan said, "But how to do it, you have to figure it out yourself, just like the 'isochronism' of a pendulum, I believe that as long as you are willing to study, you can also discover other 'isochronisms'." 'Phenomenon."

Jin Dahu assured: "Your subordinate will definitely do my best."

After saying this, Zhu Yuan turned to the two small scales.

The first miniature version of the large scale was scaled down dozens of times. It looked like a delicate model, with the weighing platform at the bottom and connected to the upper beam and weight through a lever structure.

The second is the kind of laboratory balance that Zhu Yuan once remembered, with items on one side, weights on the other, and graduated weights in the middle.

Jin Dahu also introduced that the two small scales are made according to the standard of 戥子, the smallest can be weighed to 1 centimeter, which is one hundredth of 1 yuan, and the largest can be weighed to 1 tael.

Zhu Yuan asked Shangli to find a few copper coins and weigh them with great interest.

Very precise.

However, Jin Dahu took the initiative to raise the problem: the miniature scale connected through the transfer lever, because of the complicated structure, is not very accurate, especially after a long time of use.In addition, the balance scale is more accurate because of its relatively simple structure.

Zhu Yuan thought it made sense.

So he quickly made a decision, and later asked someone to send the scale to the palace to Lao Zhu, with some thoughts of his own.After that, let the Ministry of Industry make a batch for teaching or distribute to various departments of the imperial court.

The main advantage of a balance scale is that it is easier to operate than a scale. In the future, various majors in various universities, especially those that require a large number of experiments, will have a lot of weighing needs. A scale like a steelyard, compared with a simple balance Scales are very inconvenient to carry around.

Not only that, but if you do more, it can also be sold.

It just so happens that the imperial court wants to issue pure silver coins, and the demand for weighing in all walks of life will increase significantly in the future. After all, it doesn’t matter how much copper coins are more or less. Silver coins... the size of a soybean is equivalent to the later 100 yuan. 1 cent is 1 yuan, which is not acceptable.

Then he turned to the spring sample sent by Wei Ye.

On the same day, he said casually, and then sent word to discuss several times. Zhu Yuan finally determined that the thickness of the mattress is half a foot, about 15 centimeters, and the height of the spring is 4 inches, with several layers of strong and various skins.

There are only springs in sight.

Among them, the steel wires of the spring steel are thick and thin, and the diameters of the springs are also different. This is also discussed before. No deformation possible.

Zhu Yuan had no objection.

At that moment, pulling and fiddling for a while, he noticed that the steel wire breaks at both ends of the spring were carefully wrapped with fine cloth to prevent thorns from being cut, and Zhu Yuan suddenly remembered.

The springs in what used to be mattresses or sofas... seem to be... made into box springs.

That is, each spring is wrapped in cloth.

Zhu Yuan didn't know the reason, but since this is generally done in the industry, there is obviously a reason for it.

Although I remembered it, I didn't mention it.

Perhaps one of the benefits of the spring bag is to prevent the spring wire from jumping out and piercing people. However, Zhu Yuan believes that Wei Ye and the others will not make such a mistake in details, just like the two ends of the springs at this time are carefully covered. It's like winding up.

Then it doesn't matter.

After all, fabrics are still very valuable in this era and can be used as currency, and each spring is held up, which is also an expense.

More in the future.

After seeing things and saying something, Zhu Yuan served tea to see off the guests.

After sending Jin Dahu and Wei Ye to leave, Zhu Yuan immediately came to the backyard of the inner house.

Big mattress!

After entering the main room here, the mattress has been moved in and arranged in the master bedroom on the east side.

Zhu Yuan walked in, and Xieyi was leading a group of maids to tidy up. Lu Bai, who didn't show much these days, was there, but he was standing beside him, looking at the big mattress with disgust on his face, and he almost said that it was too unfair. It's over.

indeed.

Seeing it with his own eyes at the moment, Zhu Yuan finally realized how big the one foot long and one foot wide he casually ordered before.

Anyway.

so big……

The four sides of the bed stand erected and curtains are put up, looking at it, it doesn't look like a bed, but more like...a room.

Taking a look, Zhu Yuan casually grabbed Lu Bai who was about to leave after saluting: "Go up and jump up, this is a spring bed, very comfortable."

Liu Bai was held back by his lord, and he had no choice but to stop, but said: "My lord... let sister Xieyi go up, I can't bear it."

Talking and leaving.

Zhu Yuan continued to pull, but Nizi didn't dare to use force, but she refused to go forward.

Zhu Yuan pretended to be angry: "I just talked to Xiaoyu, you are the most disobedient around me."

Liu Bai was immediately vigilant: "That girl... chews her tongue to see if I don't tear her mouth apart."

Zhu Yuan: "..."

Chewed?
It seems to have.

It seems... not at all.

Does not speak count?

So he teased: "If you want to tear Xiaoyu's mouth, I'm afraid you won't be able to beat it, my sack is the water lady."

I remember that when I was still in Mingzhou, Zhu Yuan was assassinated, and a certain girl came out of the water dragging one person and one head, so it became a strange story in Dinghai County. '.

Now I don't know if there are any villagers who set up temples.

Liu Bai is obviously not afraid: "The water lady will lose her prestige when she comes out of the water. I will tear her mouth off later."

Nizi struggled lightly as she spoke, Zhu Yuan didn't insist any more, let her go, and pleaded for the sack with a smile: "Be gentle, be careful that she really hits you when she is in a hurry. Also, I haven't seen you for a few days. Come on, give me a kiss..."

Zhu Yuan turned his face sideways while speaking.

Liu Bai was reluctant, but seeing the anxious expressions of the girls around him, he would not let him go, so he leaned over and pecked Zhu Yuan on the cheek.

Then he left in a hurry with his face flushed.

After Liu Bai ran away, Zhu Yuan stepped forward, and Cai Sang and Chai'er immediately opened the curtain a little.

Zhu Yuan didn't bother to open the bed sheet to see what the cushion looked like, so he sat on it directly, bumped it up and down, it was soft and bouncy, it felt...very right.

The sofa can also be started!
So she reached out to Xieyi: "Come on, let's take a nap here today."

Xinyi also shook her head: "There are many things to do," she said, motioning to the maid beside her: "Let Cai Sang and the others accompany them, it just so happens...it's so big."

After all, there was still a bit of yin and yang in the tone.

It's so unorthodox.

Zhu Yuan lay down and rolled, feeling more right, raised his feet, Qing Ping and Dian Jiang next to him smiled and stepped forward to help his adult take off his shoes, Zhu Yuan rolled all the way to the innermost side, and rolled back again.

back and forth.

Standing by the side, Xieyi saw that her adults, who were always too mature in daily life, rarely showed a childish side, and inexplicably stopped caring, and even took the initiative to signal to Caisang to let them go up too.

The six girls really wanted it all, but they couldn't understand Sister Xieyi's state of mind at this time, and they seemed awkward.However, the mentality of fighting for favor is greater than the scruples about Xinyi, and he quickly climbed up.

Then it was disliked.

"A group of small hairtails, go down."

So I can only go down.

Still wronged.

Why do the masters of other families like their tender little daughters, but my own... why is it different.

After chasing a group of youngsters away, Zhu Yuan continued to roll, but he said: "Falling, unreliable, blowing the horn, hopeless, lingering, exhausted, uneven, shaking..."

Listening to Xieyi, of course she understands, she actually thinks that her own adult's preference is not normal.

But also helpless.

After Zhu Yuan read more than ten times and couldn't think of it anymore, Xie Yi said in a soft voice with a bit of pampering: "Got it, Dad... Slave, go and call them over."

"uh-huh."

Actually, Zhu Yuan had no other ideas.

I just want to try how many people can lie side by side on this big bed.

After all... I am a data junkie.Data lovers like to measure and collect all kinds of data at any time, which is normal!
As Xieyi said, she didn't leave immediately. When her lord was tired from rolling around, she went up in person, first helped her take off her thick coat, and then covered her with a quilt, leaving two maids, Caisang and Chai'er, to take care of her. before leaving.

Today is the twentieth of the twelfth lunar month, and the end of the new year has come. As the housekeeper of the huge Pingzhang mansion, there are indeed too many things in Xinyi's daily life.

However, he still came to the front first, and after explaining to a group of women to go to the back to accompany his adults for a lunch break, he turned to his own affairs.

When a group of women with different charms dressed up carefully and came to the backyard, they found that their adults, who had been tired all morning, had already fallen asleep.

In the weird bed as big as the room, the little boy is sleeping peacefully. From the eyes of some of the women who can write poems and paintings and are inevitably sentimental after experiencing changes, this scene...is quite lonely.

Lively and lonely.
