HIRAM S. MAXIM AND THE MAXIM MACHINE GUN.
Statisticians inform us that the entire loss of life in wars between so-called civilised countries from the year 1793 down to 1877 had reached the enormous amount of four million four hundred and seventy thousand. To many persons these figures convey a sad and salutary lesson. But, leaving the sentimental part of the subject aside, all will readily unite in admiring the wonderful mechanism which makes the Maxim Machine Gun an engine of terrible destructiveness. Stanley provided himself with this formidable weapon, to be used defensively in the expedition on which he started for the relief of Emin Bey. It obtained a gold medal at the Inventions Exhibition, and has been approved of, if not actually adopted, by many governments.
Rifle-calibre Maxim Gun.
Its rate of firing—770 shots a minute—is at least three times as rapid as that of any other machine gun. It has only a single barrel, which, when the shot is fired, recoils a distance of three-quarters of an inch on the other parts of the gun. This recoil sets moving the machinery which automatically keeps up a continuous fire at the extraordinary rate of 12 rounds a second. Each recoil of the barrel has therefore to perform the necessary functions of extracting and ejecting the empty cartridge, or bringing up the next full one and placing it in its proper position in the barrel, of cocking the hammer, and pulling the trigger. As long as the firing continues, these functions are repeated round after round in succession. The barrel is provided with a water jacket, to prevent excessive heating; and is so mounted that it can be raised or lowered or set at any angle, or turned horizontally to the left or to the right. The bore is adapted to the present size of cartridges; and the maximum range is eighteen hundred yards. The gun can therefore be made to sweep a circle upwards of a mile in radius.
Nor is the gun excessively heavy, its total weight being only one hundred and six pounds, made up thus: Tripod, fifty pounds; pivot (on which the gun turns and by which it is attached to the tripod), sixteen pounds; gun and firing mechanism, forty pounds. The parts can be easily detached and conveniently folded for carriage, and may be put together again so quickly that, if the belt containing the cartridges is in position, the first shot can be delivered within ten seconds. It would therefore be extremely serviceable in preventing disaster through a body of troops being surprised. Reconnoitring parties, too, would deem it prudent to pay greater deference to an enemy's lonely sentry on advanced outpost duty if the latter were provided with this new Machine Gun, instead of the ordinary rifle.
Immediately below the barrel of the gun, a box is placed, containing the belt which carries the cartridges. The belts vary in length. Those commonly used are seven feet long, and capable of holding three hundred and thirty-three cartridges; shorter ones hold one hundred and twenty cartridges; but the several pieces can be joined together for continuous firing. Single shots can be fired at any time whether the belt is in position or not—in the former case by pressing a button, which prevents the recoil; in the latter, by hand-loading in the ordinary way. To start firing, one end of the belt is inserted in the gun, the trigger is pulled by the hand once, after which the movement becomes continuous and automatic as long as the supply of cartridges lasts. At each recoil of the barrel, the belt is pushed sufficiently onward to bring the next cartridge into position; the mechanism grasps this cartridge, draws it from the belt, and passes it on to the barrel. Should a faulty or an empty cartridge find its way in, and the gun does not go off in consequence, there is of course no recoil to keep up the repeating action, and the mechanism ceases to work until the obstruction is removed.
To devise and adjust the necessary parts of the machine with such precision that each part performs its proper function at the exact moment pre-arranged for it—to do all this while the gun fires at the enormous rate of six hundred rounds a minute, must have cost an immensity of thought, of labour, and of time.
The 'Colt Automatic Gun,' a new machine gun manufactured by the Colt Firearms Company, of Hartford, Connecticut, promised in 1896 to be a rival to the Maxim, as it fired 400 shots a minute.
Hiram S. Maxim was born in the state of Maine in 1840, and in his fourteenth year was apprenticed to a carriage-builder. From his father, who had a wood-working factory and mill, he learned the use of tools and derived his inventive turn of mind. After some experience in metal-working in his uncle's works at Fitchburg, he was in turn a philosophical instrument maker, and on the staff of some ironworkers and shipbuilders. About 1877 he became a consulting electrical engineer, a branch of science which he studied and became master of in a short time. Some of the earliest electric lights in the States were devised and erected by him. He was in England and Europe in 1880 in order to investigate electrical methods there. He was back in London in 1883, and after that visit, like Siemens, he made it his headquarters. What leisure he now had (1883-4) on hand he devoted to inventing his automatic machine gun, which should load and fire itself, and the British government was the first to recognise its merits and adopt it. The making of it has been taken over by the Maxim-Nordenfelt Gun Company, which has a capital of about two millions sterling.
Like Edison he has taken out about a hundred different patents, some of which are connected with oil motors and smokeless gunpowder. His flying-machine, as described in his paper at the British Association in 1894, burns oil fuel, which developed three hundred and sixty horse-power. It was driven at sixty miles an hour horizontally, and the machine contained an aeroplane sloping six degrees to the horizon. The weight to be lifted was eight thousand pounds. After running nine hundred feet, the machine exerted an upward thrust of two thousand pounds greater than its own weight. The machine, after one thousand feet, broke loose; the steam was shut off, and it fell. The experiments have been conducted at Bexley, in Kent, where Mr Maxim had a light track of railway laid down, sixteen hundred feet long, on which the machine moved. The back part of the machine having been liberated from the check-rail too soon caused the accident at the experiment, and sent the whole machine off the track. There is sufficient evidence that it did rise from the ground, and Lords Rayleigh and Kelvin have become believers in its possibilities. This machine, as described at the time, with its four side sails and aeroplanes set, is over one hundred feet wide, and looks like a huge white bird with four wings instead of two. It is propelled by two large two-bladed screws, resembling the screw-propellers of a ship, driven by two powerful compound engines.
