According to Ma Whistle's original plan or some overly optimistic estimate, he was going to improve the sewing machine first, and then apply for a patent along with the jeans to save some time.

But he soon realized that the improvement of the sewing machine would not be possible for a while.

The second-hand sewing machine he bought did not yet have a foot pedal device, which was an obvious shortcoming, and it was a good solution for him.

However, the sewing machine is not a simple machine, at least for the non-professional Ma Whistle, the sewing machine is already complex.

In any complex machine, it is almost impossible to rely on just one or two key improvements to get everything right.

Just like writing code, inserting a new piece of code in the middle will most likely bring a bunch of new bugs, and you need to adjust it repeatedly to really complete the improvement.

So Ma Whistle gave up the plan to make a new sewing machine and focused on the patent for jeans.

The jeans should be patentable for two patents, one for its exterior design and the other for the rivets on it.

Ma Whistle is not optimistic about the former. Even in later generations when the patent system was more perfect, the appearance patent of clothing did not have much significance, and imitations were all over the street.

The current patent system is full of loopholes, and this kind of patent is naturally even more flawed.

Ironically, eight years ago, a fire broke out at the U.S. Patent Office, and as a result, tens of thousands of patents — including those for fire hydrants — were gone.

The fire improved the U.S. patent system a lot, but it was still very rudimentary compared to later generations.

Therefore, registering a patent for the design of jeans, which is basically a name, has no practical significance, and may even be judged to be no innovation at all, so that it cannot pass the patent examination, and others should imitate the imitation, and the plagiarism should be plagiarized.

The more valuable thing is the rivets on the jeans.

Because this can actually be counted as a technology - reinforcement technology.

These rivets are not ornaments, but they have made jeans so durable that in the original history, the inventors of jeans even designed a two-horse logo that resembled a scene from the Magdeburg Hemispheric Experiment, where two horses pulled the jeans in opposite directions to show their sturdyness......

As a practical technology, its patent is more meaningful.

Therefore, the core patent of jeans should be "a rivet reinforcement technology applied to pants".

Ma Whistle reviewed the relevant regulations on patent applications and drafted application documents.

Written documents are secondary, the most important being the patent model.

The patent model is literal, specifically, the horse whistle needs to provide a pair of jeans with rivets, and the example is shown.

The reason for this is that the staff of the patent office are often not sufficient to understand the principles of most inventions on paper alone.

You can't blame them for their poor level, after all, inventions are all new things, and they involve all walks of life, and it is not easy to understand and review.

Drawings, textual descriptions, and finished jeans as a model are the official materials for the patent application.

Ready to prepare the materials, the horse whistle called Thomas, Floyd, and another black police officer and handed them the materials.

"This is the application material for the patent, that is, what needs to be sent to the patent office." Ma Whistle said.

Thomas looked at the material: "There are two patents? ”

Ma Whistle: "That's right, one is the exterior design of cargo pants, and the other is rivet reinforcement technology. If the former can't be taken, forget it, and the latter must be taken. ”

"And six revolvers, two each, for your self-defense on the road."

"Three hundred dollars is more than enough to apply for two patents...... If you encounter some greedy patent office staff, you know what to do. The sentry handed the gun and the coin to each of the three, "It's better to get the application done quickly." ”

"I know." Thomas nodded expressionlessly.

"In addition, choose some fabrics similar to canvas, that is, strong and wear-resistant, preferably blue, and buy some samples to bring back." Ma Whistle said again.

Canvas was only the material of early jeans, not the most suitable material for jeans.

The fabric that really belongs to jeans is called "denim", that is, the kind of blue fabric that was all over the streets in later generations.

But Ma Whistle didn't know what this cloth was, so he could only ask people to buy some samples and come back for him to identify.

Thomas and Floyd rode out of town on fast horses and headed southeast.

They will first arrive at the famous Santa Fe Trail and then follow the road east, soon into the first state in the east, Missouri.

Strictly speaking, Missouri is not considered eastern, and it is more appropriate to call it central.

But Missouri is at least a proper state with a state government, and it is also in the east, so it is not wrong to be counted in the "eastern region," at least in the eyes of the westerners.

In contrast, the Kansas, let alone the state government, does not even have an appointed governor, not even a territory, and is nominally part of the United States.

This state of "anarchy" will continue for a long time in the Midwest, and as for the reason, the most important thing is, of course, slavery - it is okay to have a state, but is the new state a slave state or an abolitionist state?

Now there are still more than ten years before the Civil War, and the conflict between the North and the South has become more and more prominent, the North wants to abolish slaves, and the South wants animal slaves, but the two sides are still maintaining a balance.

If a new state is set up, this delicate balance is bound to tilt somewhat, or even be completely upset.

In such a situation, large areas of unorganized territory are naturally the most acceptable option.

The three of Thomas went east to apply for patents, and the horse whistle continued to organize tailors to produce jeans.

He broke down the jeans process into several parts and assigned them to the town's skilled housewives to complete the task at home, and then took the finished product to Mary to settle the bill.

This is a reference to the production method of the assembly line, although the assembly line may have appeared when Qin Shi Huang made the terracotta warriors, but until now, this production method has not been popularized on a large scale.

Of course, this distributed jeans assembly line is rough, but it still allows workers who do not have factories to have a production efficiency that is not weaker than that of factory work.

Pair after pair of jeans were produced, and the old canvas was rapidly consumed.

During this time, the main job of the horse sentry was to train the town's Apache soldiers and black policemen, constantly instilling in them the concepts of discipline and law.

In the process of indoctrination, he also had some worries and confusion in his heart: discipline and law will always be perfect, but what about faith?

Ma Whistle found that he could not think of a suitable faith, either among the Aborigines or in Clarktown.

It cannot be said that there is none, religion is not it, and religion is still useful in terms of unity and stability.

But his resistance to this thing was too strong, and in his opinion, the god stick was probably the most shameful profession in the world.

Even if I die, I will never be a god...... Wait, no! How is this like the rhythm of the law of true incense, you can't say that!

Thinking of the terrifying scene revealed by this sentence in the context of the law of true incense, a trace of cold sweat could not help but ooze from Ma Whistle's forehead.

Finally...... What kind of faith should you choose?
