Chapter 235: Canvas and Sewing Machine

Watching the operator skillfully complete the shooting demonstration of this machine gun with an upgraded long-range firing mechanism, Xia Lin found that in addition to the slow rate of fire and the lack of sustained firepower, the reliability of this machine gun is really good, at least the ten machine guns used to participate in the demonstration did not have any failures.

In fact, the slow rate of fire is not necessarily an advantage for the current new army, and anyway, the current level of logistics and supply of the new army is not high, and they really do not have the financial and manpower to support the machine gun that can burst out with hundreds of rounds of ammunition in two or three minutes.

"Well, it looks like you're doing a good job this time! I will order 150 of these machine guns from the gun factory in the name of the deputy division commander of the new army, that's right! Have you decided on the name of this type of machine gun? ”

With this in mind, after watching the whole process of the demonstration, Xia Lin nodded with satisfaction and asked.

"Master Faun only completed the test and finalization of the machine gun yesterday, and he hasn't had time to name it yet, so why don't you ask Boss Xia Lin to name this machine gun we developed!"

The head of the Ide workshop hurriedly said.

"Then this machine gun will be named the Type 92 light machine gun, it's simple and easy to remember, you go back and quickly arrange and organize the production line of the Type 92 light machine gun, within a week, can you complete the production of fifty Type 92 light machine guns?"

Xia Lin naturally continued the naming habit he brought from his previous life, and determined the name of the first light machine gun developed by the gun factory, and then he asked with some concern.

At present, the third round of large-scale recruitment of the new army is almost over, and the current situation of the 6,000-strong new army is that two dissatisfied brigades constitute a dissatisfied new division, and the status of Xia Lin and Ley Rand, who was transferred to take over the position of Viscount Hart, has also risen to the rank of deputy division commander and division commander.

For an army of this size, even if it is necessary for training, it must at least be equipped with this number of machine guns, but the production of machine guns is not as good as that of rifles with simple structures, so Xia Lin is naturally a little worried.

"That's not a problem, if you need it, we can quickly organize two production lines, which can produce almost twelve Type 92 machine guns a day, which is more than enough for seven days a week."

With such a guarantee, the head of the Yide workshop looked a little unconfident, and Xia Lin saw that he was hesitant and hesitant, so he asked:

"Is there something else that needs to be solved?"

“…… Yes, Boss Xialin, although we can produce these machine guns in time, there is still a problem if we want these machine guns to come in handy, that is, the canvas bullet chain we produce may not be enough.

At present, there are only 12 female workers in the R&D workshop, and they can sew 14 or 5 canvas elastic chains in a day, and there are many substandard products in them.

If it is placed in the Type 92 machine gun, it is easy to cause jamming and other failures, and there are only about four or five that can be used, and so many machine guns, we must at least configure 1,500 canvas bullet chains. ”

"I see, this problem is easy to solve! I will arrange for some female workers in the textile factory to produce canvas chains, and there should be no shortage of them by then.

But how do you sew these canvas chains now? Take me to see it! ”

Xia Lin nodded clearly, the canvas bullet chain is a continuous ammunition feeding method proposed by the inventor of the previous Maxim machine gun, this elastic chain is made of canvas that is resistant to wear and strength, which is light and convenient, and it is also easy to manufacture.

Because in essence, the canvas bullet chain is a canvas belt with some metal plate structure to isolate the bullet, and there is no need for industrial production, a slightly more skilled female worker can sew it out by hand as long as he understands the principle and gropes for it, which is also the reason why Xia Lin adopted this kind of bullet chain when designing the Type 92 machine gun, compared with the canvas bullet chain, the manufacturing difficulty of the magazine that requires stamping equipment in the modern sense is much higher.

Xia Lin only mentioned this method of feeding ammunition on the drawings, and the specific content was all figured out by Master Faun himself, and Xia Lin was also very curious about how the canvas was sewn into this kind of elastic chain.

Naturally, the director of the Yide workshop would not refuse Xia Lin's request, and immediately took Xia Lin to the R&D workshop to find the textile women who were sitting at a large square table filled with small pieces of perforated steel and cut canvas.

They are the easiest and relatively well-paid group of people in the gun factory, doing the same sewing work as in the textile factory before, but the pay is double the salary of the gun factory, at most a little more danger of in-situ explosion in the gun factory and the constraints of secrecy regulations.

For this reason, these female workers are also quite attentive to their work, sitting at their workstations with their heads bowed, comparing the long rulers fixed on the large square table, and sewing the canvas pieces in their hands with thick twine according to the given spacing.

Xia Lin noticed that there seemed to be a kind of grouping among them, the female workers on the left were responsible for sewing the canvas sheets into the canvas belt, and the female workers on the right were responsible for sewing the metal sheets into the sewn canvas belt, and it seemed that Master Faun had also gained some from the assembly line work that Xia Lin carried out in various factories.

However, no matter how focused he was, a canvas belt more than one meter long and thirty-one pieces of metal on it were still quite troublesome to sew, and the efficiency of this hand-sewing made Xia Lin shake his head in his heart, and naturally had the idea of using machines to improve their work efficiency.

Like this kind of fixed sewing operation, Xia Lin feels that it can be completed by an old-fashioned sewing machine, which is known as one of the three major parts in a certain era in Xia Lin's previous life, which is composed of four parts: the head, the base, the transmission and accessories, and there are almost more than 100 parts in total, which looks a little complicated, but in fact the structure and principle are very simple.

Specifically, the foot pedal is used to drive the crankshaft and the runner, and the head runner is further driven to provide the power required by the sewing needle, so that the sewing needles of different specifications pass through the cloth on the feeding teeth, and the top thread on the sewing needle is driven and the pendulum shuttle below, the pendulum shuttle will make the top thread expand into a coil below, and in this process, another bottom line wrapped around the bobbin core below will pass through this loop, and tie it with the needle after pulling the upper coil, so as to complete the whole sewing process.

This sewing process does not need to thread the needle and thread manually, the female worker only needs to pay attention to control the spacing of the stitches, and use her feet to provide the power required by the sewing machine, so that she can quickly complete the sewing work of the fabric, and the overall work efficiency is more than ten times higher than that of manual spinning.

The best thing is that this kind of old-fashioned sewing machine first appeared in the eighteenth century, and although the processing accuracy requirements have increased slightly with the evolution of time and the increase in structural complexity, it is also within the tolerance of the machine shop in the industrial park.

After letting the head of the Yide workshop rest assured to organize the production line of the Type 92 light machine gun and complete the large-scale production of the light machine gun as soon as possible, Xia Lin returned to his office in the industrial park to make drawings for a few days, and successfully drew the drawings of the sewing machine.

In order to reduce the difficulty of processing and manufacturing, Xia Lin deleted the lifting tooth shaft, tooth frame and supporting presser foot from the drawings of modern foot operated sewing machines that he had memorized, and at the same time replaced the wheel-shaped swing shuttle with less efficient but simpler structure, and the crankshaft transmission structure inside the head was also changed to a connecting rod transmission structure with more parts but lower processing difficulty.

In this way, the technical difficulty is almost reduced to the level of the nineteenth century in the previous life, and with a group of skilled dwarven craftsmen on hand, it can be processed with the current machine tools.

After arranging the manufacture of the sewing machine, Charlin welcomed another unexpected visitor, and that was Fez Louienn. Since he saw him, it should be that there is news about the few things he asked Her Majesty to take the lead before, but it has only been a few days, but Xia Lin didn't expect Fez Louis to deal with it so quickly, it seems that it is quite good to have such a person who helps him communicate in all aspects at the top.
