Neither the Newcomen steam engine at the beginning of the eighteenth century nor the Watt steam engine at the end of the eighteenth century used rubber.

It was only in the early to mid-nineteenth century that rubber began to enter industrial use.

Because of the word piston, people subconsciously think that it is soft, and rubber should be used. So in other words, the piston of the steam engine is also called the steam top.

The steam top is cast in pig iron.

Including traditional devices, they have nothing to do with rubber.

Of course, the role of rubber is unparalleled, playing a huge role in the second industrial revolution, but it did not appear in the first industrial revolution.

Zhu Gaochi only knew the principle, and Xiao Jiu regarded the steam engine as the best machine.

Both subconsciously felt that the best materials should be used.

What material is the best in Daming?

Wrought iron, five iron, nine iron.

The steam engine factory has an iron-smelting workshop, and all kinds of molds are available, and Xiao Jiu does not allow forging, so it is simpler.

Using the original casting, molten iron is introduced into the mold of the previous piston mud tire, cooled and formed, and becomes a test top.

That is, the piston.

"It's not hard enough, so it's good?" Wan San rushed over, and the old face was full of confusion.

"Just use it."

Xiao Jiu's tone was affirmative.

"The hardness is not good enough, the previous hardness was good, but the steam cylinder can't stand it, and it is easy to be worn, so that it often leaks."

The head of the class is Xiao Jiu's fifth senior brother.

He was surprised when he heard this: "According to what you said, it is not good to use the best, didn't we get the wrong direction from the beginning?" ”

Xiao Jiu stared at the master.

"You kid, look at what the master does." Wan San had a black face.

Xiao Jiu couldn't help but complain.

The master wants to show his ability and come up with the best craftsmanship, and it is really the master who led them crookedly, but he will definitely not blame the master for the responsibility.

If it weren't for Master Wang's suggestion, wouldn't he have fallen into a misunderstanding like the master.

"Alright, let's get started." Lao Wu pulled back Xiao Jiu, waved his hand, changed the piston steam engine, and began to operate.

The workers were busy, and it didn't take long for a low voice to sound and float through the workshop.

The surrounding workers cheered.

Compared to the harsh sound made before, the sound of the machine just heard is so pleasant.

"Click, click."

With the movement of the piston in the 495 mm cylinder, the sound of the machine should be like this.

In the past, people worked around the steam engine and had to endure the unusually harsh sound of iron rubbing, which made people's ears very uncomfortable.

Even if it was for their own ears, they all wished Xiao Jiuxin success in his attempt.

Wan San's brows furrowed.

He was highly skilled, and he knew early on that harsh sound that the cylinder and piston were fighting each other.

Since there is a confrontation, it means that there is a problem.

Either the cylinder failed or the piston failed, so he tried his best to improve the various components.

He even began to improve the method of smelting iron, hoping to smelt better iron.

It turned out that I was wrong.

Got the direction wrong from the start.

"Xiao Jiu, you are out of school."

Xiao Jiu didn't hear, "Master, what did you say?" ”

"I said." Wan San pulled Xiao Jiu's ears, and in Xiao Jiu's painful expression, he said loudly, "You out. Division. now."

"Senior brother, congratulations."

Lao Wu looked at Xiao Jiu enviously, and the master didn't say that he was out of school.

Out of the teacher.

It means a lot to their apprentices.

Their level is naturally qualified when placed outside, but the master has different requirements for them, and he will not easily smash his signboard.

"Master."

Xiao Jiu looked at the master reluctantly, he didn't want to be a teacher, what did he have if he couldn't get out of the teacher, he had no ambition.

"Don't put on this face, I will call you a master outside in the future, and you can't be childish anymore." Wan San sighed.

Xiao Jiu didn't say anything more.

He didn't have much to think about, and as soon as he solved the piston problem, his mind immediately threw himself into the steam engine, whether to use the original lever transmission or the new way.

Soon after.

When Zhu Gaochi came to the factory, someone rushed to report the good news, informing him that the steam engine had made a big breakthrough, and that its service life and air tightness had been greatly improved compared with the previous one.

"Can you use a coke refinery?" Zhu Gaochi asked happily.

"Yes."

"Where's Xiao Jiu?"

"Master Xiao Jiu is studying transmission parts."

"Let's take a look."

Zhu Gaochi rushed to the workshop with great interest, and soon found Xiao Jiu in the pile of parts.

The workshop where Xiao Jiu is located is a workshop specially vacated for experiments.

Wansan also comes often.

However, he is still a big foreman, and he needs to deal with the technical problems encountered in the workshop, and the foremen of each class also have to manage.

So the workshop did not finish Wansan, there were only a few craftsmen.

"Xiao Jiu, congratulations."

"The eldest prince also knows?" Xiao Jiu's face was shy, and he felt embarrassed.

It didn't seem like much of a deal to him.

As a result, everyone congratulated him when they met, and the master said that he was a teacher, and everyone knew about it, which made him very embarrassed.

I didn't want to go out anymore and stayed in the workshop.

"Such a big happy event, how can we not know, you should also take a breath, it is the design of the railway, and the improvement of the steam engine, and I have been tired for many days."

"Let's take a vacation with you and rest for three or five days."

Xiao Jiu's head shook into a rattle.

"I just like to stay in the workshop, I don't like to take holidays."

"You should go back and see your parents, too."

"My parents are very nice." Xiao Jiu said stupidly.

Zhu Gaochi was speechless.

Although it will not return to his hometown with wealth and wealth, with Xiao Jiu's current status, he is already very dazzling among ordinary people.

Not everyone can be an official.

Just say that Wansan is good, and wherever you go, you will not be called a master by the people.

When relatives and friends do things, they will feast Wansan, and in the eyes of the people, Wansan is already a group of people with status in the township.

Of course.

Scholars are still the most precious.

It is not common for people to have a reputation for reading in the township.

Xiao Jiu has a simple personality and doesn't know how to show off, which is also a good thing, and it is easy to feel happy in life, Zhu Gaochi did not persuade again.

Everyone has their own way of living, and some people like things, maybe Xiao Jiu doesn't like them, but they will be troubled.

"What are you studying?"

"According to the eldest prince." Xiao Jiu pointed to a pile of parts, his hands were covered with smudges, "Transmission." ”

"Do you have a new idea? Do you think gearing is better? ”

Zhu Gaochi said tentatively.

In ancient times, there were gear transmission and chain transmission, as well as rope transmission, crank transmission and so on, and the transmission device of the steam engine was the most common crank transmission in Northeast Taicun.

The Newcomen steam engine also used a crank transmission, and the later Watt steam engine used a gear transmission.

Zhu Gaochi didn't know where the steam engine had progressed, so he naturally wouldn't easily decide that it was appropriate to use gear transmission.

Several transmission devices have been unearthed in the Qin and Han dynasties, including many traditional tools that have been preserved in the countryside in later generations.

But so.

Zhu Gaochi will not bring it up easily.

It's not a secret, and he doesn't need to keep it a secret from his own workers, especially Xiao Jiu.

Xiao Jiu's understanding of several transmission devices is much better than that of himself, so he naturally doesn't need to point out by himself.

It is the most correct thing to provide direction and some future theories, otherwise it is easy to add to the snake.

Now that Xiao Jiu has encountered a problem, he cautiously raised it.

Xiao Jiu shook his head.

"The gear transmission is not good, it can't keep up with the speed of the piston of the steam engine, it is easy to lose the teeth and damage the machine, and it will also weaken the power."

Gearing for Watt steam engines.

Zhu Gaochi did not refute.

He already knew about the improvement of the steam engine.

It may be that the parts of the current steam engine have not yet matured to the point of the Watt steam engine, and what Xiao Jiu said may not be wrong.

Regarding the reward, Zhu Gaochi did not speak again.

It's better to tell his master about this.

There is no need to let Xiao Jiu be troubled by human feelings.

It's really not easy for me to be a little prince, like a nanny.

Alas.

It's too rolly, isn't it easy?

Zhu Gaochi shook his head and patted Xiao Jiu's thin shoulder, and sure enough, Xiao Jiu didn't get up to send himself.

Leaving the workshop, Zhu Gaochi called out to Wan San, and the two came to the open space of the factory.

"Little Wangye, I want to talk about patent fees." Wan San took the initiative to say.

"Yes, we're still thinking about how to talk to Master Wan."

"This matter is all up to the little prince, Xiao Jiu, this kid has a tendon character, fortunately I met the little prince, we have been reluctant to let him out, just because I am afraid that his temperament is easy to cause trouble."

Regarding Wan San's words, Zhu Gaochi agreed very much.

Not to mention the present, even in the future, people with too simple personalities are also easy to be deceived.

For example, Tesla in the West was miserably pitted.

"The patent term of Wansan steam engine is three years, Xiao Jiu improved your steam engine with your permission, and he is your apprentice, we want to hear your opinion."

What does it mean to value talents? Listen to other people's ideas.

Wan San didn't expect that the noble man would ask himself, and after a moment of silence, he said slowly: "Xiao Jiu has improved the piston, and the piston will be used in the steam engine in the future." ”

"For each steam engine, we have five taels of silver, and we will give two taels of silver to Xiao Jiu."

The nobles still care about the silver.

Zhang Dehui and Zhang Dongjia left the factory, although Wan San didn't say it, he always remembered it in his heart.

Don't dare to offer to let the nobles pay more.

Two taels of silver, Wan San is also very reluctant, but Xiao Jiu has been raised by his side since he was a child and is regarded as half a son.

The patent for the steam engine is not for a lifetime.

also has Xiao Jiu's ability, and has won the favor of nobles. When he is old, he can live for a few years, and in the future, his sons and grandchildren may have to rely on Xiao Jiu to take care of him.

For Xiao Jiu's character, Wansan believes it.

"Two-two." Zhu Gaochi thought about it, it was indeed a lot.

Xiao Jiu improved the piston, just a part.

This is also something that Zhu Gaochi is embarrassed about.

Sometimes patents promote technology, sometimes it hinders it.

The advent of the Newdoor steam engine was used to pump water, but the Newdoor steam engine could be greatly promoted.

As well as countless craftsmen who followed, they devoted themselves to the study of the Newcomen steam engine, which laid the foundation for the improvement of Newcomen's technology.

Because Newcomen did not apply for a patent.

Yes.

This original steam engine was not patented, and everyone could use it for free, as well as study it.
