СКАЧАТЬ a little distance from the cutter, and parallel to it is another descending rod, which is called the guide; and this guide is so connected with the cutting tool, by means of a very complicated and ingenious machinery, that the latter is governed rigidly and exactly in all its movements by the motion of the former. Now there is placed immediately beneath the guide, what is called the pattern, that is a cavity in a block of iron of precisely the form and size which it is intended to give to the cavity in the wooden stock. All that the workman has to do therefore, when the machine is put in motion is to bring the guide down into the pattern and move it about the circumference and through the centre of it. The cutting tool imitating precisely the motions of the guide, enters the wood, and cutting its way in the most perfect manner and with incredible rapidity, forms an exact duplicate of the cavity in the pattern. The theory of this operation is sufficiently curious and striking – but the wonder excited by it is infinitely enhanced by seeing the work done. It is on this principle substantially that all the machines of the Stocking Shop are constructed; every separate recess, perforation, or groove of the piece requiring of course its own separate mechanism. The stocks are passed from one of these engines to another in rapid succession, and come out at last, each one the perfect fac-simile of its fellow.

      DIVISION OF LABOR

      We have said that the number of separate parts which go to compose a musket is forty-nine; but this by no means denotes the number of distinct operations required in the manufacture of it – for almost every one of these forty-nine parts is subject to many distinct operations, each of which has its own name, is assigned to its own separate workman, and is paid for distinctly and by itself, according to the price put upon it in the general tariff of wages. The number of operations thus separately named, catalogued and priced, is three hundred and ninety-six.

      These operations are entirely distinct from one another – each constituting, as it were, in some sense a distinct trade, so that it might be quite possible that no one man in the whole establishment should know how to perform any two of them. It is quite certain, in fact, that no man can perform any considerable number of them. They are of very various grades in respect to character and price – from the welding of the barrel which is in some points of view the highest and most responsible of all, down to the cutting out of pins and screws of the most insignificant character. They are all however regularly rated, and the work that is performed upon them is paid for by the piece.

      ASSEMBLING THE MUSKET

      When the several parts are all finished, the operation of putting them together so as to make up the musket from them complete, is called "assembling the musket." The workman who performs this function has all the various parts before him at his bench, arranged in boxes and compartments, in regular order, and taking one component from this place, and another from that, he proceeds to put the complicated piece of mechanism together. His bench is fitted up expressly for the work which he is to perform upon it, with a vice to hold without marring, and rests to support without confining, and every other convenience and facility which experience and ingenuity can suggest. With these helps, and by means of the dexterity which continued practice gives him, he performs the work in a manner so adroit and rapid, as to excite the wonder of every beholder. In fact it is always a pleasure to see any thing done that is done with grace and dexterity, and this is a pleasure which the visitor to the Armory has an opportunity to enjoy at almost every turn.

      The component parts of the musket are all made according to one precise pattern, and thus when taken up at random they are sure to come properly together. There is no individual fitting required in each particular case. Any barrel will fit into any stock, and a screw designed for a particular plate or band, will enter the proper hole in any plate or band of a hundred thousand. There are many advantages which result from this precise conformity to an established pattern in the components of the musket. In the first place the work of manufacturing it is more easily performed in this way. It is always the tendency of machinery to produce similarity in its results, and thus although where only two things are to be made it is very difficult to get them alike, the case is very different where there is a call for two hundred thousand. In this last case it is far easier and cheaper to have them alike than to have them different; for in manufacturing on such a scale a machinery is employed, which results in fashioning every one of its products on the precise model to which the inventor adapted the construction of it. Then, besides, a great convenience and economy results from this identity of form in the component parts of the musket, when the arms are employed in service. Spare screws, locks, bands, springs, &c., can be furnished in quantities, and sent to any remote part of the country wherever they are required; so that when any part of a soldier's gun becomes injured or broken, its place can be immediately supplied by a new piece, which is sure to fit as perfectly into the vacancy as the original occupant. Even after a battle there is nothing to prevent the surviving soldiers from making up themselves, out of a hundred broken and dismantled muskets, fifty good ones as complete and sound as ever, by rejecting what is damaged, and assembling the uninjured parts anew.

      To facilitate such operations as these the mechanism by which the various parts of the musket are attached to each other and secured in their places, is studiously contrived with a view to facilitating in the highest degree the taking of them apart, and putting them together. Each soldier to whom a musket is served is provided with a little tool, which, though very simple in its construction, consists of several parts and is adapted to the performance of several functions. With the assistance of this tool the soldier sitting on the bank by the roadside, at a pause in the middle of his march, if the regulations of the service would allow him to do so, might separate his gun into its forty-seven components, and spread the parts out upon the grass around him. Then if any part was doubtful he could examine it. If any was broken he could replace it – and after having finished his inspection he could reconstruct the mechanism, and march on as before.

      It results from this system that to make any change, however slight, in the pattern of the musket or in the form of any of the parts of it, is attended with great difficulty and expense. The fashion and form of every one of the component portions of the arm, are very exactly and rigidly determined by the machinery that is employed in making it, and any alteration, however apparently insignificant, would require a change in this machinery. It becomes necessary, therefore, that the precise pattern both of the whole musket and of all of its parts, once fixed, should remain permanently the same.

      The most costly of the parts which lie before the workman in assembling the musket is the barrel. The value of it complete is three dollars. From the barrel we go down by a gradually descending scale to the piece of smallest value, which is a little wire called the ramrod spring wire – the value of which is only one mill; that is the workman is paid only one dollar a thousand for the manufacture of it. The time expended in assembling a musket is about ten minutes, and the price paid for the work is four cents.

      THE ARSENAL

      The New Arsenal, which has already been alluded to in the description of the general view of the Arsenal grounds, is a very stately edifice. It is two hundred feet long, seventy feet wide, and fifty feet high. It is divided into three stories, each of which is calculated to contain one hundred thousand muskets, making three hundred thousand in all. The muskets when stored in this arsenal are arranged in racks set up for the purpose along the immense halls, where they stand upright in rows, with the glittering bayonets shooting up, as it were, above. The visitors who go into the arsenal walk up and down the aisles which separate the ranges of racks, admiring the symmetry and splendor of the display.

      The Arsenal has another charm for visitors besides the beauty of the spectacle which the interior presents – and that is the magnificent panorama of the surrounding country, which is seen from the summit of the tower. This tower, which occupies the centre of the building, is about ninety feet high – and as it is about thirty feet square, the deck at the top furnishes space for a large party of visitors to stand and survey the surrounding country. Nothing can be imagined more enchanting than the view presented from this position in the month of June. The Armory grounds upon one side, and the streets of the town upon the СКАЧАТЬ
