Automatic rifle

“ MACHINE GUNS IN AIRCRAFT
Various attempts have been made to mount machine guns on aeroplanes, but the operator, in his narrow seat, has hardly space to point a machine gun in any direction except straight to his front. The American Curtis machine gun exhibited at Olympia is the most efficient form yet produced, but at present the airman seems to prefer an automatic rifle. Even in the early days of the war, Sir John French was able to report that British airmen had disposed of no less than five of the enemy’s aircraft with this weapon. ”

“ They are essentially automatic rifles, designed to fire the ordinary rifle cartridge and capable of delivering a stream of small bullets at a rate of as high as 600 per minute. Experience in the European war has determined that the rate of 400 shots per minute is the desirable maximum. Their ranges are the same as for the rifle. The fire of a machine gun has been estimated as equal to that of 30 men.
562. Mounts. Machine guns are usually mounted on tripods or wheels. The weight of certain types is such that they can readily be carried by the soldier from one point to another. ”

“ All automatic arms are divided into classes, as determined by the following characteristics:
1st. Method of applying the power necessary to operate: (gas or recoil) .
2nd. Method of supplying ammunition: (belt, magazine or clip) .
3rd. Method of cooling: (water or air) .
Another well-defined distinction is made between the true machine gun and the automatic rifle; the former being so heavy that it must be mounted on a substantial tripod or other base, while the latter is so light that it may be carried and operated by a single man. Of the former class, (p. 048) the Colt, (35 lbs.) ”

“ The old, smooth-bore field-guns of the enemy would be completely disabled before they could be brought within cannon-shot of the ten thousand. As soon as the enemy came within rifle range, the ten thousand would open on them with their thousand automatic machine-guns and magazine-rifles. As an automatic machine-gun fires at the rate of 600 shots a minute, a thousand would fire at the rate of 600,000 shots a minute. The magazine shoulder-rifles would fire aimed shots at the rate of twenty-five a minute, and the quick-firing field-guns would each fire shrapnel at the rate of forty a minute. ”

“ Coming next to the more personal equipment of the soldier, we find the necessity confronting the Ordnance Department to manufacture shoulder rifles by the million and cartridges for them by the billion. The great war brought the machine gun into its own, requiring in the United States the manufacture of these complicated and expensive weapons by the tens of thousands, including the one-man automatic rifle, itself an arm of a deadly and effective type. ”

“ Its mechanism is extremely simple. It can be carried at a good pace over a distance of several hundred yards by a single man, and it is not distinguishable from the ordinary rifle except at fairly close range. It is my conviction that the automatic rifle is the key to the machine-gun problem, which has hitherto proved of such insurmountable difficulty to the Allies in the different theatres of war.
It has been said that we hold our trenches with infantry, the French with their 75-centimetre guns—“the black butchers,” as my friend, Mr. ”

“ Shoulder firearms also were comparatively slow in the early days, and liable to miss fire, and it was not until the automatic rifle of recent years was fully developed that soldiers learned to keep their distance. ”

“ This new automatic machine gun has been adopted by the United States Army, Navy and Marine Corps. It is handled by two men, one to aim and fire it, the other to feed the cartridges which are held in brass clips of 30 each. The complete gun weighs only about 35 pounds, fires 400 shots per minute, using regular 30-caliber Springfield rifle cartridges, with a maximum range of 3 miles and an effective range of about 2,000 yards. The weapon is air cooled and can be fired steadily for about 10 minutes without undue heating. ”

“ The magazine rifle is purposely made with a bolt like a door bolt, so that it can be operated easily under all conditions, but the automatic pistol, evidently to give it a neat external appearance, has no projection to take hold of to drive back the slide, which, besides, takes more strength than is required to operate the bolt of a magazine rifle. ”

“ The firing mechanism of the machine gun has always an automatic character, but the rifle has acquired this feature, so that it cannot be made a distinguishing mark: on the other hand, since machine guns have been made to discharge projectiles of such weights as 1 lb. or 3 lb. there is nothing to separate them from quick-firing ordnance unless it be the automatic firing. ”

“ They are made with one barrel and a magazine, on the principle of the repeating rifle, thus doing away with the escape of gas that takes place in revolvers between the chamber and the barrel.
Automatic pistols are so constructed that the force of the recoil is utilized to open the breech, extract the empty case, cock the pistol, reload the chamber with the top cartridge from the magazine, and close the breech, leaving the pistol ready to fire on again pressing the trigger. ”

“ Many patents have already been taken out for rifles on this principle, and several patterns have actually been constructed, in which a merely momentary contact of the breech-piece with the end of the barrel is sufficient; the recoil of the barrel with the reaction of a spring performs all the requisite movements with such rapidity that an amazing speed of firing has been obtained. It is said that such an automatic gun can send forth bullets at a perfectly amazing rate. ”

“ There are several other types of machine guns, but the most ingenious, and perhaps the most effective, is the Maxim automatic gun. This has a single barrel, about two thirds of which, from the muzzle towards the breech, is surrounded by a water-jacket into which water is automatically injected at each discharge, thus rendering overheating impossible. The mechanism for operating the gun is at the breech, covering the remaining third of the barrel. All that is necessary is to draw back the trigger to fire the first shot ”

“ When, however, concealment and protection from fire exist, it may sometimes be advisable to bring machine guns into action at decisive range. If a sufficiently large target be offered and the range be known, the concentration and rapidity of their fire will enable guns to be employed, with considerable effect, at long ranges. Machine guns should seldom engage artillery at long rifle range, for in such circumstances superiority of fire will always rest with the latter if the machines are located. ”

“ The gun’s narrow frontage in action renders it easy to conceal, and when discovered it presents a very small and difficult target to the enemy’s riflemen; on the other hand, when once discovered if it cannot be moved unseen to another position it is liable to suffer a prolonged and concentrated fire from the widely scattered riflemen of the enemy, to which it cannot effectively reply, and which must in time cause loss. Again, its range being limited, it is powerless against artillery except under special circumstances at effective rifle range. ”

“ By massing the machine guns of a brigade the assurance of fire effect at ranges beyond 1,000 yards is increased, and it is easier to control and direct fire. At shorter ranges massed machine guns may form a conspicuous target, and the control of more than two guns then becomes difficult. Occasions will, however, often arise when the massed guns of a brigade can be brought into action in a well-concealed position within the limits of effective rifle range. Under such circumstances massed guns may produce great effect both in attack and defence. ”

“ If you want a hunter, buy an English hunter; if a harness horse, buy an American trotter. In the same way, for whatever purpose you want a pistol, buy one, if by any means you can do so, especially for that purpose. Anyhow, it is useless to compete with a short-barrelled pocket automatic against target pistols. This class of pistol is intended only for self-defence at short range, and has no pretensions to accuracy. ”

“ Para. 2.—Surprise is a powerful factor in the effective employment of the machine gun; every effort must therefore be made to avoid the enemy’s observations both when advancing to a position and when in action. The machine gun possesses the power of delivering, from a very narrow front, a practically uninterrupted volume of closely concentrated rifle fire, which can be directed against any desired object with the least possible delay. The delivery of such fire cannot, however, be long sustained, because of the heavy expenditure of ammunition involved and the difficulty of replacing it. ”

“ One of the first things we discovered was that while all the small-arms ammunition issued was made pursuant to uniform specifications, furnished by the War Office, a large percentage of it was manufactured in new, hastily equipped factories, by partially trained workmen, and while it was apparently near enough to the standard to pass the tests exacted by the inspectors, only an extremely small proportion would function properly in machine guns or other automatic arms. ”

“ They may also be used to reinforce threatened points, when their mobility will enable them to arrive at a distant part of the battlefield with the rapidity of cavalry. They should rarely be used in the firing line, where their fire, being dispersed, is less effective than an equal volume of rifle fire, and where they are at once the target for every rifle. Machine guns can never engage artillery, and should avoid engaging other machine guns or firing on a line of skirmishers. ”

“ A small part of the gas generated by the explosion of the individual cartridge operates the mechanism, discharging the bullet, throwing out the empty shell and making ready for the next shot.
A machine gun is designed to enable one man to fire the equivalent of a volley, or series of volleys, discharged by an entire platoon (one-third of a company) of infantrymen. As at present developed, it represents a step toward the evolution of a shoulder-rifle that will throw a continuous stream of bullets. ”

“ In action five cartridges are always going through some process of loading, while five empty shells are in different stages of ejection. The latest type, fitted with an electro-motor, will fire at the rate of one thousand rounds per minute, and eighty rounds have actually been fired within ten seconds! It is not, however, safe to work these machine-guns so fast, [Pg 98] as the cartridges are apt to be occasionally pulled through unfired and then explode among the men’s legs. The automatic guns, on the contrary, as they only work by the explosion, are free from any risk of such accidents. ”

“ All guns must be so placed that they can be retired under cover of the ground immediately they move. [133] The guns on the higher ground will open fire at long range, and the opportunity may be afforded at this stage for using “deliberate” fire at the most rapid rate possible, in imitation of rifle fire, for the double purpose of concealing the guns and deceiving the enemy by causing them to believe that the position is held by infantry. The guns at the lower position should watch their opportunity for opening fire on a large and vulnerable target ”

“ If it has one misfire in every twenty shots, or so, it does not matter, the great thing being to have it cock easily. An automatic pistol is the weapon for this, a revolver being quite out of date. A very big front sight and a big “U” in the back one are advisable.
As the target rises, “come up,” quickly, increasing the pressure on the trigger as you “come up,” so that the pistol goes off the moment it is horizontal and the sights are about right. I say about because there is not time to correct the aim. ”

“ In the modern “automatic” machine-gun, moreover, the loading, firing, extracting and ejecting are all performed automatically by the gun itself, either by the recoil of its barrel, or by a small portion of the gases of explosion being allowed to escape through a minute hole in the barrel near the muzzle. The following details of the British Maxim, Hotchkiss and Colt types are reproduced from the article “Machine-guns,” Ency. ”

“ The breaking of any other part of the gun will be an accident of rare occurrence and, provided the gun is properly inspected before use, may be more properly classified under accidents than failures. A modern machine gun in the hands of experts should never jam, while failure of [25] automatic fire will be rare and momentary. Until this standard has been reached a machine-gun detachment cannot be considered fit to begin tactical training. The Japanese in the late war were obliged to improvise the detachments for their hastily acquired machine guns ”

“ You will therefore not have to aim so far in front with an automatic pistol when shooting at moving objects, and not have to take so high an aim at distance objects to allow for the drop of the bullet—as with a revolver. ”

“ It is assumed that you have procured an accurate pistol, properly sighted. It is best to use a single-shot pistol or revolver as an automatic pistol cannot well be used as a single loader and for a beginner is very dangerous with the magazine charged.
First, make sure that it is unloaded. Always do this before handling a pistol.
Take a bottle of sight-black and paint both sights over with the liquid. I have seen men try to compete, with their sights in a shiny state, which made it impossible for them to make good shooting on a white target with black “bull.” ”
