Lippincott's Magazine of Popular Literature and Science, December 1878

Sweden comes next, and the scene changes; for the weapon which suggested the remarks was only, as it were, one gun in a garden. Instead of wine and olives we find iron and furs. Except some Indian steels, there is no better metal than that of Sweden, and horse-shoe nails are made of it all over Europe and the United States. Iron in ore, pig, rails, bars, rods, wire; iron in tools, files, wheels, balls, shells, pans, boilers, stoves, springs; iron ad lib.

The agricultural machines of Sweden, like those of Denmark, are copies of the American and English, and the same is true to a large extent of the engines, saw-mills, water-wheels and wood-working machinery. The statement would not be true of the very elaborate exercising-machines (la gymnastique médicale mécanique) invented by Gustave Zander of Stockholm. They embrace every conceivable variety of effort, and also another class of applications which may be termed shampooing, as they consist of kneading and rubbing. Among the twenty machines are those designed for flexing, stretching and extending the limbs, for kneading the back and neck, for rubbing the body and limbs to induce circulation and simulate the effect of exercise in the cases of weak persons or those confined to their beds by casualties. Some of these were in Philadelphia in 1876.

Steering-apparatus and gun-harpoons for whaling testify to the maritime character of the people, as do the boats and ropes. The great exhibit of pâte de bois shows the anxiety of the people to turn their extensive forests to good account in the markets of the world. White pine seems to be the principal wood thus used. Norway and Sweden have been shipping timber for some centuries, and yet seem to need no laws to restrain the denudation of their hills; certainly not to encourage rainfall. Bergen has 88.13 inches per annum, which is just double that of Philadelphia, and four inches greater than that of Sitka, where the people say it is always raining. Of course these figures are small when compared to spots on the Himalayas, where Hooker observed a fall of 470 inches in seven months, and on one occasion 30 inches in four hours; the latter equal to the average annual rainfall of France.

The American machinery, which occupies a position between Norway and England, is creditable in kind and quality, but fails very far in giving a correct idea of the multiplicity of our industries. Almost the only evidence of our textile manufactures are two of Tilt's Jacquard silk-weaving looms. The telephones of Edison and Gray excite unremitting astonishment and admiration, and have both received the highest possible awards. Our wood-working is practically shown in a large variety by Fay & Co. of Cincinnati, and one or two other special machines by other makers. The Wheelock engine, which drives all the machinery in our section of the main building, has very properly been awarded a grand prize. It is all that can be desired in an engine, and has a singular simplicity of construction, with few working parts. It is the same which drove the machinery in the Agricultural Building at the Centennial. The steam is admitted and exhausted by a valve at each end of the cylinder placed directly below the port. The cut-off valve is behind the main valve: the mechanism for operating the valves is on the outside of the steam-chest, and easily accessible. The valves and seats are made tapering in their general diameter, and the pressure of steam comes on one side, also acting to keep the collar in contact with the sleeve.

The Waltham Watch Company is considered by some of the most influential European journals as the most important in the American section on account of the revolution it is making in that important industry. When the Swiss commissioner went home from the Centennial he published a letter fairly throwing up the sponge, and when the company's exhibit appeared for the first time in Europe at an international exposition it was regarded as carrying the war into Africa. The American system of making by machinery all the parts of an article—say, of a watch—of a given grade by means of gauges and templets, so that the parts may be "assembled," and of such singular exactitude in their making that any part may be replaced by the corresponding piece of any other watch of the same grade, has in this manufactory attained its highest results, greatest precision and most perfect illustration. The whole collection of watches was sold within a few weeks after the opening. The latest improvements in the balance to secure perfect isochronism under varying conditions of temperature would delight the soul of Harrison, who worked from 1728 to 1761 on the problem of a compensator for the changes of rate due to the expansion and contraction of the metal, and received the reward of twenty thousand pounds sterling offered by the Board of Longitude.

Tiffany's exhibit has been admired and patronized, but is not quite within my range of subjects. Darling, Brown & Sharpe have their machine-tools and gauges, Bliss & Williams their presses and dies. We have the Baxter, Snyder and Lovegrove portable engines, Taylor's and Aultman's agricultural engines. Our railroad exhibit is not very full: we have a Philadelphia and Reading coal-burning locomotive, a Pullman car, the Westinghouse brake, Stephenson's street-cars, car-wheels from Baldwin's and Lobdell's: the latter also sends calender-rolls of remarkable quality. As a sort of set-off to the Austrian car-wheels which have run for twenty-one years, as previously mentioned, Lobdell has a pair which have run 245,000 miles on the Missouri, Iowa and Nebraska Railway. The Fairbanks scales in great variety, both of size and purpose, and of a finish and an accuracy which have become proverbial; the Howe scales; the Goodyear boot- and shoe-machinery; Stow's flexible shaft; Lechner's coal-mining engine; Allen & Roeder's riveting-machine; and Delamater's punches and shears,—are a few more of the representative machines.

Sewing-machines are not in as great variety in the American section as they were in Philadelphia. There are, however, enough of American and European to foot up about eighty exhibitors. Wheeler & Wilson's have been awarded the grand prize, and there are various medals for others, both home and foreign—the American machine, Cole's and Wardwell's among the number. The various hardware exhibits, such as the Disston saws, Ames shovels, Collins axes, Batcheller forks, Russell & Erwin builders' hardware, as well as the Remington, Colt, Winchester, Sharpe and Owen Jones rifles and revolvers, and the Gatling and Gardner guns, are a little on one side of my present line of subjects.

The United States has preserved its ancient reputation in its agricultural machinery. We are especially strong in the class which we term "harvesters," the name including reapers, automatic binders, mowers, horse-rakes and hay-loaders. Our baling-presses also are in advance of competitors. A juryman may perhaps stand excused for supposing that more than an average amount of interest is felt in the machinery which happens to be in his class, but on Class 76—"agricultural implements in motion and in the field"—additional interest was conferred by a series of competitive trials extending from July 22 to August 12, and embracing reapers, mowers, steam and ordinary ploughs, hay-presses, threshing-machines especially, but also including all the other machines for working in the ground, gathering crops and the storage and preparation of feed for animals. In this series of competitive trials eight different countries entered the lists. The prizes were twelve objets d'art placed at the disposal of Monsieur Tisseraud, the "director-general of agriculture and horticulture of France," and the jury selected to attend the trials. Eleven of them were accorded to machines of "exceptional merit," the idea of novelty being included in the definition of the term. These objets d'art are Sèvres vases worth one thousand francs each, and in view of their exceptional value, and the large share that America has in the award, a list of the names may very properly be appended.5 Several hundred machines competed: for instance, twenty-six reapers, sixteen mowers, fifty-four ploughs, and so on of numerous kinds of agricultural implements and machines for working in the soil, gathering crops and for the work of the homestead and barn.

Last on the foreign side is the British machinery, and the collection is very much larger and more varied than any of the preceding. There are few lines of manufacture which are not represented here. Machines for working in iron and other metals, for sawing and fashioning wood, for the ginning, breaking or carding of cotton, flax, wool, jute and hemp, for working in stone, glass, leather and paper, are shown. Then, again, the finished productions; prime motors, such as stationary engines, locomotives and fire-engines; lifting-machines for solids or liquids, cranes, jacks, elevators, pumps, each in endless variety.

Prominent in the hall, and employed in driving the machinery, is the large double compound horizontal engine of Galloway of Manchester. This form of engine is coming to the front, as is evinced especially in the marine service. Maudslay & Sons of London exhibit a model of the four-cylinder marine compound engine as fitted on the "White Star line" vessels, the Germanic, Britannic, Oceanic, Baltic and Adriatic, and on the steamers of the "Compagnie Générale Transatlantique," the Ville de Havre, Europe, France, Amérique, Labrador, Canada. The vessels of the New York and Bremen line have the same class of engines, built in Greenock, Scotland.

Amid so large a mass of machinery one can but select the most prominent, and among these we may choose such as, while not necessarily imposing in size, are suggestive of ideas which we may find valuable for home introduction. Appleby & Sons lead the world in the completeness and capacity of their great cranes and lifts for docks and wharves, machine-shops, erection of buildings, and travelling cranes for railways or common roads. We must make one exception—the elevators for hotels and warehouses, in which America is in advance of all other countries. While we have many varieties of these, we must give credit where it is due, and the ascenseur Edoux of Paris is the original of all those in which the cage is placed upon a plunger that descends into a vertical cylinder into which water is forced to elevate the plunger, and from which it is withdrawn to allow the plunger and cage to descend. Very fine specimens of this class of elevator are in the New York Post-office building. The gantry crane of Messrs. Appleby Bros. of London is the most complete engine of its kind in the world. It was originally constructed for the growing requirements of the docks of the North-eastern Railway Company of England at Middlesborough. The term "gantry" is applied to the movable scaffold or frame, which in this case rests upon a pair of rails twenty-three feet apart, one of them being close to the edge of the quay. The clear height is seventeen and a half feet, which allows the uninterrupted passage of locomotives and all kinds of rolling-stock on each of the two lines of rails which are spanned by the gantry. The crane is designed for a working load of five tons, with a maximum radius of twenty-one feet from the centre of the crane-post to the plumb-line of the lifting chain, with a capacity for altering the radius by steam to a minimum of fourteen feet. The crane has capacity to (1) lift and lower; (2) turn round completely in either direction simultaneously with the lifting and lowering; (3) alter the radius by raising or lowering the jib-head; (4) travel along the rails by its own steam-power. All these motions are easily worked by one man, who attends to the boiler. The travelling motion is transmitted from the crane-engines by suitable gear and shafts to the travelling wheels, and warping-drums or capstans are fitted on a countershaft on the inner side of each frame, which drums can be driven independently of the travelling wheels for moving trucks into position below the crane as they are required for loading and unloading. Smaller cranes may pass with their loads below the gantry, and a number of these large cranes may be assembled so as each to work at the different hatchways of a large screw steamer, or two may be associated together for any exceptionally heavy lift. The value of elevation of the crane is not only in allowing the loaded cars to be brought on tracks beneath it, but in giving it capacity to work over the sides of large vessels, which when light may rise twenty feet above the level of the quay, and to load or discharge from trucks on two lines of rails on the land-side of the gantry, overhead of the trucks on the two lines which run below the gantry.6

Blake's stone-breaker, though only represented by model in the United States section, where it belongs, is shown by two English firms; and though some Europeans profess to have improved upon its details, no efficient substitute has been found for it, but it remains the premium stone-crusher of the world, and has rendered services in the exploitation of gold quartz and silver ores, and in the crushing of stones for public works and for concretes, which can hardly be exaggerated. In testimony taken in the United States in 1872 it was put in evidence that five hundred and nine machines then in service effected a direct saving over hand-labor of five million five hundred thousand dollars per annum.

Steam-pumps are here in force—direct by Tangye and others, and rotary by both of the Gwynnes, whose name has been so long and is so intimately associated with this class of machines.

The emery-wheels of Thompson, Sterne & Co. of Glasgow have the same variety of form and application usual with us, but the firm claims that while it uses the true corundum emery of Naxos, the American article is only a refractory iron ore, which soon loses its sharpness and becomes inefficient. This is a question of efficiency or of veracity which we leave to the trade. The machine adapted as a tool-grinder has six emery-wheels for varying characters of work. Four are assorted for gauges of different radii, for moulding-irons, etc. One has a square face for plane-irons, chisels, etc. One is an emery hone to replace the water-of-Ayr stone.

In examining the English locomotives exhibited two things were apparent: one half of them have adopted the outside cylinders and wrist-pins on the drivers, three out of four have comfortable cabs for the engineers. These are, as we view them, sensible changes. Outside-cylinder engines are also coming into extensive use in France. The machine tools shown by Sharp, Stewart & Co. of Manchester are remarkably well made, and their locomotive in the same space is an evidence of the efficiency of the tools.

The exhibit of hydraulic-machine tools by Mr. R. H. Tweddell is a very admirable one, and shows a multitude of stationary and portable forms in which the idea is developed so as to reach the varying requirements. When work is more conveniently held to the machines, the latter are adapted to reach it whether presented vertically or horizontally, or with one arm inside of it, as with boilers and flue-pipes. When it is more convenient to handle the riveter, the latter is suspended from a crane and swung up to its work, and the peculiarity of the various sizes and shapes for different kinds of work is remarkable. The cut shows one of the latest for riveting girders.

The Ingram rotary perfecting press, on which the Illustrated London News is worked off, prints from a web of paper of the usual length, and is claimed as the final triumph in the line of inventors, which is thus stated in England: Nicholson, König, Applegarth and Cowper, Hoe and Walter. We should be disposed to add a few names to the list, among which would be Bullock and Campbell. A is the roll of paper, containing a length of, say, two miles; B B the type and impression cylinders for printing the inner form; C C calendering rollers to remove the indentation of the inner form type; D D the outer form type and impression cylinders; E E cylinders with a saw-tooth knife and an indentation respectively to perforate the sheet between the papers; F F rollers to hold the sheet while the snatching-rollers G G, which run at an increased speed, break the paper off where it has been indented by E E. The folder is in duplicate to give time to work, as each only takes half the papers. The vibrating arm H delivers the sheets alternately to K and J, which are carrying-tapes leading to two folding-machines. If the sheets are not required to be folded, the arm H is moved to its highest position, and there fixed, without stopping the machine: it then delivers the sheets to the roller L, and by means of a blast of air and a flyer they are laid on a table provided for them.

The rise of British factory-life and great energy in manufacturing began with the invention of the spinning-frame by Arkwright, the power-loom by Cartwright, the spinning-jenny by Hargreaves, and the mule by Crompton—all within a space of twenty years ending 1785. To these must be added the steam-engine by Watt, which made it possible to drive the machinery, and the gin by Eli Whitney, which made it possible to get cotton to spin. Much as iron has loomed up lately, the working of the various fibres—cotton, wool, flax, hemp and jute—constitutes the pet industry of her people, and very elaborate and beautiful are the machines at the Exposition, especially attractive and less commonly known being those for working long or combing wool, flax, hemp and jute. The United States is not doing as much as it ought in the working of these fibres, and the money which is paid for the purchase of foreign linens and fabrics made of other materials than cotton and wool might, some economists think, be employed at home in making them. The day will come probably, but does not seem to be hastening very fast, when we shall conclude to make our own linens, as we have within a comparatively few years past determined in regard to all the staple varieties of carpets.

One of the most important machines in the Exposition, from the American point of view, is the "double Macarthy roller-gin," exhibited by Platt Brothers & Co. of Oldham, England. It is a curious instance of how machines sometimes revert to their original types. The oldest machine for ginning cotton is undoubtedly the roller-gin, and it was known in India, China and Malaysia long before Vasco da Gama turned the Cape of Good Hope and opened the trade of the East to the Portuguese and their successors. The common roller-gin of Southern Asia was shown at the Centennial from Hindostan, Java and China, and is exhibited here from Java. It has a pair of rollers about the size of broomsticks, close together and turning in different directions, which pinch and draw the fibre through, while the seeds are prevented from passing by the closeness of the rollers. Whitney's invention of the saw-gin in 1794 revolutionized the business and changed the whole domestic aspect of our Southern States. In it the fibre is picked from the seed by means of saw-teeth projecting through slits in the side of the chamber in which the seed-cotton is placed. But the roller-gin has again come upon the stage, and with the late improvements is likely to become the gin of the future. When the close of our civil war put an end to the "cotton famine," as it was called, in Europe, and American cotton resumed its place in the market, the export of the East Indian and Egyptian cottons would have been immediately suppressed if they had not possessed the roller-gin in those countries. Ten thousand of the double Macarthy gin are used in India, and five thousand of the single roller-gin in Egypt. It is understood that the saw-gin is used in but a single district in India. While the saw-gin injures any variety of cotton by cutting, tearing, napping and tangling the fibres, its action upon the long and fine staple called "sea island" is ruinous, and the roller-gin alone is suitable for working it. The slow action of the single roller-gin, cleaning about one hundred and fifty pounds of lint per day, made its cultivation too expensive, but the double roller-gin will clean nine hundred pounds in ten hours, or one hundred and twenty pounds an hour of the common upland short-staple cotton. It is thought by Southern members of the United States commission that the introduction of the double roller-gin into our country would greatly increase the profitableness of the culture of cotton, and especially of the "sea island," which is at present much neglected, and in the growth of which we need fear no rivalry. Each roller is made of walrus leather, and rotates in contact with a fixed knife, dragging by its rough surface the fibres of cotton between itself and the knife. A grating holds the seed-cotton. Besides these parts there are moving knives to which are attached a grid or series of fingers. At each elevation of the moving knives, the grids attached thereto lift the cotton to the elevation of the fixed knife-edge and of the exposed surface of the rollers: on the descent of each moving knife the seeds which have become separated from the fibre are disentangled by the prongs of the moving grid passing between those of the lower or fixed grid about seven hundred and fifty times per minute, and are by this rapidity of action flirted out.

It would be scarcely fair to neglect altogether the English annex in which all the agricultural implements are exhibited, nor that which contains its carriages. So much commercial intercourse, so many journals published in the respective countries, have made each pretty well acquainted with the agricultural machines and methods of the other. The principal difference is in the splendid plant for steam-ploughing exhibited by Fowler & Son and by Aveling & Porter, and in the great number and variety of the machines and apparatus for preparing food for animals—chaff-cutters, oat- and bean-bruisers and crushers, oilcake-grinders, boilers and steamers for feed and mills for rough grinding of grain.

A shed by the annex contains two curious machines for working stone—one a dresser, belonging to Brunton & Triers, which has a large wheel and a number of planetary cutters whose disk edges as they revolve cut the stone against which they impinge. The other machine, by Weston & Co., is for planing stone mouldings. The stone-drills are in the same annex; also the Smith and the Hardy brakes, the former of which is the European rival of the Westinghouse, acting upon the vacuum principle, and already in possession of so many of the lines in Europe that it proves a serious competitor.

Perhaps nothing in the French Exposition excites more surprise in the minds of those who are conversant with technical matters than the immense advance of the French since 1867 in the matter of machinery. The simple statement of the names of the exhibitors, their residences and the subject-matter occupies a large volume, and the quality and variety are equal to the quantity.

Reference has been made to the web perfecting printing-machine in the English section, but quite a number are shown in the French department, three of them by Marinoni of Paris, one of which prints the journal La France, eighteen thousand an hour. It prints, cuts, counts, folds and piles the papers. Another by the same maker prints twenty thousand an hour of the Weekly Dispatch (English paper), and counts and piles them in heaps of one hundred each. A third works on the Petit Journal, printing forty thousand per hour with two forms. Alauzet & Co. have also a web perfecting press, à double touche, for illustrated papers and book-printing. This wets, prints, cuts, counts and folds in octavo four thousand per hour of super-royal size. They also show a double railway topographic press, printing in two colors. Vauthier's roller-press is arranged to work on an endless roll of paper or on sheets fed in as usual, and prints in six colors. Electro shells are secured in position on the respective rollers, which are in horizontal series, and the paper is conducted by tapes to the rollers in succession. The French section shows a great variety of polychrome, lithographic and zincographic printing-machines, and also a great number of ordinary job and card presses, the most interest, however, centring in the large number and variety of the web perfecting presses for newspapers and for bill-work where long numbers are required.

France has a right to exemplify the Jacquard in its fulness, for it is hers. The original machine of Vaucanson and that of Jacquard are in the Conservatoire des Arts et Metiérs, as well as a long series of exemplifications of successive improvements. The Grand Maison de Blanc of Paris has a large one, making an immense linen cloth of damask figures, all in white, and representing what I took at first to be an allegorical picture of all the nations bringing their gifts to the Exposition. I found afterward that it was called Fées du Dessert. It is about three mètres wide, and just as long as you please to make it, but the pattern is repeated every five mètres. The design, on paper, is hung against the wall, and is twelve by eight mètres, all laid off in squares of twelve millimètres, and these again into smaller ones exactly a square millimètre in size. The number of small squares on the sheet of paper is ninety-six million, which represents the number of the intersections of the warp and woof in the pattern. There are nine thousand and sixty-six perforated cards in the Jacquard arrangement for floating the threads which form the damask pattern, and the whole machine stands on a space of about twenty by twelve feet and is eighteen feet high. It is worked by one man, without steam-power, the shifting of the harness being done by two foot-levers and the shuttle thrown by a pull-cord.
