The Romance of Industry and Invention

by Unknown

Where one of the canals has been conducted into a square-shaped basin, the older and principal buildings of the manufactory have been located. They form a quadrangle of some extent; and here, too, are situated the offices and the quarters of the executive staff, which is composed partly of civilians and partly of military officers. Behind these, on the east side of the enclosure, and on the banks of one of the canals, are rows of workmen's cottages. Near the entrance gates are situated schools for the workmen's children; and at the other end of this street, as we may call it, is a church, which is served by the clergy of the parish of Enfield. On the west side extend north and south the flat meadows or marshes which form so convenient a spot for the testing and proving of the rifles.

All sorts of personal weapons required for the arming of a soldier in the English army are made here, not only firearms, such as rifles and revolvers, but lances, swords, and bayonets, the last having now become a sort of short sword. There is also one class of weapons which occupies a sort of intermediate position between those carried by the soldier himself and those drawn by horses—that of machine guns, as they are called, which, though not carried by men on their shoulders or in their hands, are drawn about by them on small carriages. These machine guns are classed with personal arms, because they are usually employed in connection with infantry; and also because—which is a far more important reason—the ammunition required for them is similar to that used in rifles. In fact, they are in principle only a collection of infantry rifles fastened together, or, as we shall see, a single rifle barrel with machinery attached which enables it to discharge with great rapidity.

There is one more general principle which we shall do well to bear in mind before we enter the factory. It is this, that of course the manufacture of small-arms is in as much a condition of uncertainty as that of larger warlike weapons in these days. What we see now may become obsolete in a very short time, and we shall be shown specimens of firearms which formed the universal weapons of the British army only a very few years ago, but are now as much out of date for practical purposes as cross-bows. Remembering this, let us go first when we enter to one of the offices, where we shall see arranged in a rack against the wall, amongst others, specimens of the old Enfield muzzle-loader, of the same weapon converted into a breech-loader, of the Martini-Henry rifle, and of the latest pattern of all, the magazine rifle. While, stored away in some out-of-the-way corner, it is just possible we might come across a specimen of the old smooth-bore or 'Brown Bess,' which formed the weapon of certain English linesmen so late as the beginning of the Crimean War.

The Enfield workshops are of course in appearance much like other workshops. There are the same processes of forging and casting, and the same machinery for hammering and turning and boring and drilling which we see elsewhere.

A rifle, as every one knows, consists of three portions—the wooden stock, the barrel, and the lock. The stock is usually made of walnut wood, and is manufactured in what we should perhaps describe as a carpenter's shop. Formerly, the stock of a rifle was formed out of one long piece of timber; but now the complicated machinery of the breech and lock cannot be contained in a hollow in the wood, as was formerly the case, but has to be enclosed in a steel case, to which the wooden butt and barrel support are screwed. To the rifles of the newest pattern there hangs, just below the lock, the magazine, in which are carried five or, in some cases, ten cartridges, which spring up into place in turn, ready to be discharged. In short, the rifle has become, as regards its rapidity of action, something similar to a revolver pistol. We shall find that a lock has in its manufacture to pass through an almost infinite number of processes, each part having to be forged or beaten out till the whole can be fitted together.

Let us pass on to the barrel-making shop. Rifle barrels are made from a solid round bar of steel, which is at first considerably shorter and stouter than the finished barrel will be. This steel bar is heated red-hot, and is passed between several pairs of rollers, which convert it outwardly into the required form. It has, however, afterwards to be bored and then rifled—that is, furnished with the spiral grooves within, which gives the bullet the necessary spin. Of course the barrel is by far the most important portion of a firearm, and the barrels of rifles are, at Enfield, tested and proved in the most ingenious and searching manner. The first proof takes place after the barrel has been bored, but before it is rifled. The barrels are loaded with cartridges of considerably greater weight both in powder and bullet than those which will be used in them when they are ready for service, and are enclosed in a sort of strong box which has one side open. They are then discharged through the open side into a heap of sand, and examined; but it is a rare event to find a barrel that has not been able to bear this test. The second proof, which takes place after the rifling, is of a similar character.

But these proofs are only to test the strength of a barrel; the test of its accuracy is a much more delicate operation. Of course the machinery by which it is bored and rifled works with the most admirable precision; but yet it is necessary to put this machine-work to trial. There are, amongst others, two highly ingenious methods for doing this. In the one case it is placed on a stand which is so constructed that on it the barrel can be made to revolve rapidly. The barrel is pointed towards a window, and in front of it is a fixed sight. The workman looks through it while it is revolving; and if the sight remains steady to his eye, that is a proof that the barrel may be said to be straight. But there is yet another method. The mechanism of this testing apparatus is rather difficult to describe, but is something of this fashion. The barrel is made to revolve as before; but this time there is inserted in it a spindle, on which is fixed a short arm with a point which touches very lightly the interior of the barrel. If there is any inequality, or if the barrel is not perfectly straight, this short arm is of course shaken, and when this is the case, the motion is further communicated to a long arm at the end of which is an indicator, which is looked at by the workman through a magnifying glass.

Barrel, stock, and lock being at last completed and tested, the rifle is put together; but even then it is subjected to one more trial. This is carried out on the proof-ground in the marshes, and takes the form of an actual discharge of the weapon at a target. The rifle is screwed to a fixed and firm support, and then a certain number of rounds are fired at ranges of five hundred and one thousand yards respectively. In this test the hitting of the centre of the target, or 'bull's-eye,' is not the end in view, as it is in ordinary target practice. That sort of shooting depends of course on the steadiness with which the marksman holds the rifle. In this case, however, the fixed rest may be directed on any portion of the target, and the grip will always be the same. The only object of the test is to see whether the rifle throws the bullet at each round on or near the same spot. A marker at the butt examines the position of each shot, and the smaller the space on which they strike, the better the weapon.
