In fact, the days of being confined at home, it is impossible to really be idle, in addition to the daily instructions and reports of the family and the army, paying attention to the girls' development courses, sometimes teaching them in person, and sorting out the three views of my personal characteristics, I have also been able to regain the leisure time of the hobbies of the year.

At this time, Ah Lu played the role of a kind of Cheng dù as an assistant in my experimental workshop, and in fact she had played a similar role in the past.

It's just that as the daughter of the lord of the domain, following behind her brother and tinkering with some strange things, it is just regarded as some kind of child's play by most people, but not many people pay attention to it.

Then I sorted out my old bits and knick-knacks again, classified them into a catalog, and then sent them to the place where I should go according to my instructions and intentions.

Then my study became a temporary showroom, full of all kinds of small objects that were dismantled and modified.

In front of me was an ugly mechanical shelf, with all sorts of gears and levers and shafts stacked on top of each other, emitting a kind of uniform sisoo sound, which was in fact a primitive table clock.

In fact, this era is in the stage of evolution from large bells to small bells,

The Southern Dynasty already had a large self-propelled timekeeping tool improved from the armillary sphere, but it was driven by water power, and the same name was the water meter clock, and the bell towers and bell towers all over the city's square area, as well as the bells that tell the time one after another every day, are also a major feature of Guangfu.

Among them, the water transport instrument elephant platform made by the Inner Construction Institute for Qin Tianjian is the most ambitious, it is a device that combines an armillary sphere, an armillary elephant and a mechanical timer, and occupies several large buildings on a whole high platform.

It uses hydraulic power as the power source, has a scientific escapement, is about 2 meters high, seven meters square, and is divided into three layers: the upper layer discharges the armillary sphere for astronomical observations; The middle layer can simulate celestial bodies for synchronous demonstration; The lower layer is the heart of the instrument, where the timing, time signaling, and the formation and output of the power source are all in this layer.

The more common ones are only basic chronograph and departure chime.

At the same time, a small number of powerful people also built a room-sized water meter clock in their own courtyard, and then decorated it with floral colored bricks and porcelain, specially opened a canal to divert water as a drive, which is not only a garden landscape, but also a tool for keeping time and telling the time.

What my workshop is working on is to reduce these large and extensive bulky machinery to at least put on the back of a carriage or pack horse, and march with the army because of the preliminary solution of spring materials, with the feasibility of mechanical charging structure, because the rest is the miniaturization of parts, a variety of precision and stability of structural design requirements,

The reciprocating principle of the inertia of the center of gravity and the centrifugal coil accumulation principle of the iron spring are just the layer of paper that belongs to the layer of paper that is broken at one point for me, but for most workers and craftsmen in this era, it is a genius who thinks hard and can't do it.

So this miniaturized test with a mainspring as the power and a hairspring ±pendulum) as the speed regulating mechanism was placed in front of me, although the appearance was still very rough and rudimentary, and it seemed to be tolerant of failure, and it was not resistant to corrosion, but it had a certain epoch-making significance for the social process I knew.

Clocks that can be moved around represent more precise productivity in production and life, as well as efficiency bonuses in military operations and economic fields. You must know that most of the military in this era still use hourglass gauges as a short-term calculation tool.

As for the more advanced I-wheel escapement, or the more sophisticated fork escapement, I only know the general principle, and I don't know much else, so for now I can only continue to slowly implement and explore.

The other, a model of a vehicle, I am working on a suitable gun carriage to complement the five six-inch guns I have obtained.

Although the history of the use of artillery in the Southern Dynasties has been many years, and the casting process is not bad, it seems to have embarked on a certain crooked path in other aspects because of some kind of misfortune.

Compared with some pit father's firearms, because the artillery is said to have been used by Liang Gong before, it has inherited the corresponding technology as a descendant, and even developed and improved, such as copper tire iron smoothbore, mother and child tube and spiral gun latch, pull fire firing and so on

However, as the predecessor of the Southern Dynasty, the Nanhai Governorate in the early years mainly used artillery for the expansion of land and sea, and all kinds of warships full of artillery became the nightmare of those foreign barbarians.

Compared to the artillery used in the sailors, there are ship's sides and decks as fixed bases, and then guò ropes and pulleys are used to achieve limited rear reset and firing boundary adjustment, but this is not possible on land

Almost all the slightly larger guns and carriages of the officers and soldiers I have seen are rigidly fixed with the trunnions embedded in the square hole of the frame, so they are known for being strong and bulky.

A shot has to be shaken back a little, and then through the guò manpower reset adjustment, re-aiming, and there is no fixed door crosshair and mechanical ruler such things, but through the guò muzzle directly above the center, plus a longitudinal line, for aiming.

Therefore, a veteran gunner who has received the corresponding education in surveying and mapping and calculation, and has the sense and experience of operation, is very precious, because in addition to shooting at close range in attack and defense, the experience required for projectile shooting at a slightly longer distance can only be passed on to the veterans, which somewhat restricts the large-scale cultivation of the artillery system.

As the artillery group of the army, the first thing to do when entering the combat state is to choose a suitable ground and build the corresponding artillery fortress to avoid running and too much deviation caused by the firing process.

The main focus is on targeted attacks, which also creates a strange reality in which projectile weapons with limited recoil, such as stone cannons and crossbows, continue to coexist with artillery. After all, although the strength and life of these traditional offensive and combat equipment are not as good as those of artillery, they already have quite mature experience and systems in manufacturing, assembly, and use.

Of course, the development direction of artillery stationing technology that I know in later generations is nothing more than spring type and hydraulic type, pneumatic type, hydraulic type and pneumatic type, although relatively high, but the material and sealing requirements are very high, so I can only consider spring type.

The advantages of spring type are that the structure is simple, the action is reliable, it is not affected by temperature, and the processing and maintenance are simple and convenient; However, it is heavy and easy to fatigue after long-term use, but these disadvantages are more obvious pneumatic or hydraulic than those of later generations.

The key is the breakthrough of spring materials some time ago, it is difficult to make it smaller, but it is relatively simple to make it bigger, and the Southern Dynasty already has a ready-made shock absorbing spring for carriages.

Therefore, as a model, on the gun carriage presented in front of me, the gun body is fixed to the traction stretch frame groove rail that can slide back and forth, and a set of winding springs constitute a simple elastic cushion reset device, which connects the gun carriage with the gun body, and the gun body recoil in relation to the gun carriage for a short distance when fired, and the whole gun does not move back as a whole.

In this way, the anti-recoil device consumes most of the recoil energy and naturally resets, the force on the gun carriage is greatly reduced, and the firing angle is basically not affected, so it is relatively rigidly connected, which greatly reduces the mass of the whole gun, and also improves the firing speed and accuracy.

The cannon body used as a model is equipped with a reticle of the door, a spiral mechanical ruler is fixed on the gun carriage, and together with the monocular used by the observer, the plumb and level used by the carpenter, it naturally constitutes the basic means of observation and sighting of modern artillery.

Of course, this is only a preliminary formed sample, and it has to go through the loss and strength tests of various charges before it can constitute a real finished product.

The third is two handcuffs of different shapes, which are said to be the breakthrough brought about by the addition of the Kongjiji to the workshop, and the self-defense firearm that I asked for to be easy to fire quickly at close range.

Mainly in view of what happened before, considering the risks that I could still encounter in Guangfu, the original double-shot small handcuffs were not enough, so I specially asked the test workshop in the Tiangong to drive out two samples for me.

But after I examined it carefully, I couldn't help laughing, a curved grip and six short barrels densely arranged together in the shape of a cylinder in front of the hammer, which looked round and full of heaviness; The other, much more rudimentary, had three prismatic barrels tied together directly with iron bars, with a straight grip behind it, and a long wooden handle that looked like a short hammerhead when loaded.

Isn't this a pepper shaker pistol and a three-eyed gun, is there a providence in the dark? However, the pepper shakers came out, cut off most of the cylinder, and put the gun carriage and single barrel on it, isn't it the famous first-generation runner in history, Colt.

I thought about it, and called the enigmatic creature over to share my sense of accomplishment and achievement. After all, compared to the results of my efforts to control the army and the violent soldiers, the farming plan of my family to accumulate money and operate is in her hands.

But before I could speak, I saw the messenger in the porter.

Genjiuro brought me good news and bad news, the good news is that they have cracked down and swept up, and in the operation of the smuggler group to which Feng Shisan, he inadvertently found an island that suited my requirements and standards.

The bad news is that if I want to take possession of this island and develop it, I'm afraid I'll have to deal with some of the sailors.
