Chapter 967 Can handcuffs be used like this?
"Handcuffs?"
"Yes, they are handcuffs, simple equipment used to tie up criminals or prisoners of war." Luo Chong explained casually.
"Oh, then I will go find someone to develop a gun mechanism. I will go right away. Please wait for a moment, Chief." Lin Fei agreed and immediately went to call someone for Luo Chong.
"Yes!" Luo Chong agreed and sat in the office waiting. He had nothing to do. He saw that there were blank papers and pencils on Lin Fei's desk, so he took one and started to draw a sketch of handcuffs.
He had played with handcuffs before, and even used wires, hairpins and other things to pry the locks on handcuffs. The reason was that the principle of this thing was really super simple. It used a pair of anti-tooth mechanisms to make it rotate in only one direction to achieve the purpose of fast locking.
Inside the handcuffs, there is a toothed bar opposite to the outer ring of the iron ring. A folded spring is used to push the toothed bar outwards, so that it can bite into the teeth of the outer ring of the iron ring. By rotating the key in the keyhole, the toothed bar can be pressed down, thereby releasing the outer iron ring. Rotating it in the opposite direction will push a small iron rod into the spring, completely locking it. Of course, it can still be opened with a key.
In other words, the keys of handcuffs are universal. Even if there is no key, it can still be easily opened by using a small iron sheet to pry the spring. This thing is not difficult for professional thieves, but for ordinary people, as long as they know its principle, to pry open the handcuffs.
However, this is about the early handcuffs. Later, users also found that this thing was too easy to pry, so they invented an improved version, that is, a new type of handcuffs with two locking mechanisms. That one is more sophisticated and more troublesome, but it is not necessary for the current Han tribe.
Because no one has seen this thing yet, it will not be too late to change it when everyone knows how to play with it.
Moreover, given the current situation in the Han tribe, it is estimated that those who can get into handcuffs will not have the opportunity to study this thing.
While thinking, Luo Chong quickly drew a sketch. The freehand drawing was not very good, but he just needed to let others understand the structure and shape of the handcuffs.
Luo Chong was going to mass-produce handcuffs for the Shen Ce Guards to use when capturing prisoners on the front line. By the way, he could also make more and distribute them to local government offices in the Han tribe for them to use in daily law and order maintenance.
Not to mention maintaining law and order, the role of handcuffs is very huge in terms of capturing prisoners. Compared with traditional ropes, handcuffs have obvious advantages. First of all, they are made of metal and will not be easily worn or cut like ropes. Secondly, the speed of handcuffs is much faster than ropes.
If you subdue an enemy on the battlefield, you press him to the ground, and then want to tie his hands or feet. First of all, you can't let him move, and you have to let him cooperate with you to tie the rope.
Even if you prepare a movable noose in advance, which can cover the target's hands within one second, you still have to tie a knot to prevent the target from breaking free. By the time you finish tying the knot, it will take at least ten seconds.
Ten seconds, especially ten seconds on the battlefield, can change rapidly. In this time, a shotgun can fire five bullets. Of course, every second saved is a second.
Moreover, the environment in which they fight is the winter in the Far North. Outdoor activities in such areas will inevitably reduce the flexibility of the hands. If you don't wear gloves, there is even a risk of freezing. At this time, if you let the soldiers tie knots to tie people, they will inevitably be slow.
However, if you use handcuffs, there will be no such problem, because the handcuffs only need to be smashed on the opponent's wrist, and they can automatically rotate a circle and lock. It only takes three seconds to restrain a person, which can shorten the time of capturing prisoners by three times. In addition, the handcuffs have a simple structure and are easy to use. Even if the hands are frozen and the fingers are not flexible, the enemy can still be easily locked.
This is the purpose of Luo Chong's desire to make handcuffs.
When he had almost finished the sketch, Lin Fei called the people he was looking for over. There were two of them, a young man about 20 years old, and an apprentice of 15 or 16 years old.
"Chief, this is Ishida and his apprentice. They are the researchers in charge of the bolt mechanism. They don't have any important work at the moment, but they will take on new projects when they have time." Lin Fei brought the two people to Luo Chong and introduced them.
"Meet the chief!" Ishida and his little apprentice bowed to Luo Chong.
"Well, I won't waste any more words. This is a sketch I just drew. You two can take a look first." Luo Chong handed the drawing directly to Ishida and continued to introduce it.
"This is a new type of handcuffs, used when arresting criminals or prisoners of war. It can be quickly locked automatically and can then be opened with a key. Its locking mechanism requires a flat spring sheet and a spring made of the same material as the ejector and extractor in the gun receiver. Oh, by the way, the handcuffs in the drawing have half a ring that can rotate. Take a look at this design and see if there is any problem. If I let you be responsible for making it, will there be any difficulties?"
After Luo Chong finished speaking, Ishida looked at the sketch that Luo Chong had drawn with a surprised expression. He really didn't expect that a pair of handcuffs used to lock people could be made so exquisitely and cleverly designed.
"The chief's design is really great. At first glance, it seems to be a very simple mechanical principle, just a pair of reverse teeth and a spring. However, the flexible combination of these two structures and their use in shackles is indeed an extremely creative design.
"There is no problem with the structure. This thing is indeed quite simple. As for the material, I suggest using steel. As for the production process, use cast steel as the main body, stamp small parts with steel plates, and then use a lathe to grind out the reverse teeth, and finally use a few rivets to assemble it.
"I just don't know if the chief has any specific data on the size, such as its thickness and the size of the bracelet?"
Ishida first praised the design with admiration, then talked about his own production plan, and finally asked Luo Chong about the size of the handcuffs.
After listening to his production plan, Luo Chong nodded with satisfaction, and then said.
"Your production plan is good, just do it according to your method. As for the specific data about handcuffs, I don't have it, so I need you to investigate the data. You can randomly find people in the research institute and various factories to take samples and measure the size of their wrists and ankles. The number of samples should not be less than 100, and then conduct a comprehensive analysis and take the average value.
"I have an estimated value here, that is, the inner circle diameter of the handcuffs is about six to seven centimeters, but it is not accurate. It is just a reference. The specific data is based on the data you get from sampling.
"As for the thickness of the handcuffs, if the quality of the steel is guaranteed, they can be as thin as possible, and the lighter the better, as long as they cannot be easily broken open or damaged.
"The other thing is the design indicators. My requirement is that the handcuffs are connected by three sections of iron chains in the middle. The distance between the two bracelets cannot exceed ten centimeters. The thickness of the iron chain should not be easily broken or pulled apart. You can do experiments to get the specific data.
"Then there is the diameter of the handcuffs. It must be able to lock the wrists of all the people you can see, as well as the ankles. The ankles can be slightly tighter, which is okay, but the wrists must not be able to be broken free.
"Finally, there is the weight. My requirement is that a pair of finished handcuffs, including the key and the iron chain in the middle, cannot weigh more than one catty. If it exceeds five hundred grams, it will be unqualified.
"Okay, these are the design indicators. You can go to investigate and take samples today, and then draw the drawings tonight. Trial production will start tomorrow. I want to see the samples within three days. When the samples come out, you can bring the samples and drawings to Hanyang City to find me. "
Luo Chong quickly explained the design indicators and some of his own requirements. Ishida was also taking notes on the sketch with a pencil, and soon he wrote down all of Luo Chong's requirements.
"The number of samples cannot be less than one hundred people. The diameter of the iron ring must be able to lock a person's hands and feet at the same time. The two iron rings are connected by three sections of iron chains. The total length cannot exceed ten centimeters. The total weight of the whole pair of handcuffs does not exceed 500 grams. They must be light, durable and strong. Samples must be made within three days. Okay, leader, I have written it all down. Is there anything else to add?" After Ishida finished recording, he put his pen down, repeated it to Luo Chong, and finally asked.
"Well, there is no problem with the design indicators. To add, um, the simpler the production process, the better, and it must be easy to produce. Let me put it this way, if your sample can satisfy me, after the experiment is finalized, before winter comes today, I will ask you to produce at least 20,000 pairs of such handcuffs.
"So, you have to have a bottom line in your heart. Anyway, no matter how you produce, you have to reach this number for me. And the later you delay the finalization time, the greater the pressure of later production. Remember, I said at least 20,000 pairs, there is no upper limit!"
Luo Chong thought about it and added again.
"Yes, I understand, leader, then I will take my leave first, and go find someone to investigate and sample." Ishida nodded, and then immediately agreed.
"Well, go ahead, do a good job!" Luo Chong responded casually, and Ishida and his little apprentice bowed to Luo Chong, then turned around and left with the drawings.
To be honest, Luo Chong only gave them less than three days, which was indeed a bit tight, but it was just enough. If nothing unexpected happened,
Luo Chong would go home directly after arranging the development of handcuffs. He would not leave Hanyang City again in the short term, because Xiaodie and Zhan Ying were about to give birth, and he was worried if he went out again. Although he would not be able to play any role if he stayed, he could at least cheer them up.
Luo Chong took his guards home, but the research institute of Xingang County and the Shen Ce Guards of Hanyang County were not idle. Their training tasks were heavy, so they started formal training on the day Luo Chong left.
With the temporary organization, queue training was easy to carry out. Marching, standing still, at ease, turning left, right, and back, these are all basic operations. The purpose is to cultivate discipline and obedience, so that soldiers can develop conditioned reflexes and execute orders immediately after hearing them.
In addition to the queue, the next step is individual weapon teaching. According to the model of three classes as a group, two instructors are responsible for teaching a group. The soldiers line up and sit on the grass. The instructors hold a small blackboard and draw a simple structure diagram of the firearms on it with chalk. The soldiers look at the diagram and compare it with the firearms in their hands while explaining the operation steps of the firearms.
"Okay, that's the name of the parts of the gun. Next, you can compare the pictures on the blackboard with the guns in your hands and recognize the names of the parts. You must remember this clearly, because I will often use these words when I explain the shooting essentials to you later. Don't say you don't understand then. If you don't understand now, ask immediately." After an instructor finished speaking, he began to let the recruits identify the names of the parts of the gun by themselves.
"Report!"
"If you have any questions, ask."
"Instructor, I know this front sight. The rear sight is the same as the sight on the crossbow. What is this extra sight for?" A recruit looked at the sight on the gun and asked in confusion.
"That sight is used to adjust the height of the rear sight. By adjusting the height of the rear sight, you can aim at targets at different distances. Since you have played with the crossbow, you should know that there is also a row of scales on the sight of the crossbow. This sight is the same as that scale. By aiming at different scales, you can adjust the elevation angle of the weapon, so that the arrow or projectile can be shot at different ranges. The only difference is that the scales on the sight of the gun are divided more finely."
The instructor immediately explained to everyone after hearing the question.
"Oh, so that's how it is. I understand."
"Well, does anyone else have any questions? If you don't understand, ask quickly, otherwise I will check it out later. If you can't remember, you will be punished to do 50 push-ups." The instructor reminded the recruits again.
"Report."
"If you have any questions, please ask."
"Instructor, I can't find the firing pin you wrote on the blackboard. Why is there no flint on this gun? If there is no flint and flint, how does it ignite the gunpowder?"
"The firing pin is hidden in the bolt. You can't see it unless it is disassembled, so don't worry about it. You just need to know where it is. Another question is about igniting the gunpowder. I will draw a cross-section of a bullet for you, and you will understand."
The instructor said while drawing a cross-section of a bullet on the blank space on the blackboard, and then drew three pictures of different stages of the bullet firing process, and explained to everyone what firing powder is, what is smokeless gunpowder, and metal fixed bullets and other concepts related to new weapons.
The recruits listened attentively and shouted that it was exciting. They didn't expect that their tribe had quietly developed so many amazing gunpowder weapons. When they thought that they were the first batch of soldiers in the Han tribe equipped with such advanced firearms, the pride and pride in their hearts were even more indescribable.
