Steam power

“ To trace the effects of steam-power, in its manifold applications to mining, navigation, and manufactures of all kinds, would carry us into unmanageable detail. Let us confine ourselves to the latest embodiment of steam power—the locomotive engine. ”

“ With the advent of the steam-engine all industry bounded forward again. First harnessed by Watt, Giant Steam has become a commercial and political power. Everywhere, in mill and factory, locomotive, ship, it has increased the products which lend ease and comfort to modern life; it is the great ally of invention, and the ultimate agent for transporting men and material from one point on the earth's surface to another.
Try as we may, we cannot escape from our environment of mechanism, unless we are content to revert to the loincloth and spear of the savage. ”

“ The steam-engine itself, which supplies us with such unbounded power, owes its present perfection to this most admirable means of giving to metallic objects the most precise and perfect geometrical forms. How could we, for instance, have good steam-engines if we had not the means of boring out a true cylinder, or turning a true piston-rod, or planing a valve face? ”

“ And, last of all, with inimitable power, and 'with whirlwind-sound,' comes the potent agency of steam. In comparison with the past, what centuries of improvement has this single agent comprised in the short compass of fifty years! Everywhere practicable, everywhere efficient, it has an arm a thousand times stronger than that of Hercules, and to which human ingenuity is capable of fitting a thousand times as many hands as belonged to Briareus. Steam is found in triumphant operation on the seas ”

“ The steam-engine, second only to the press in power, has in a few years anticipated results throughout the New World which centuries, in the ordinary course of cause and event, would have failed to produce. The dullest forester, even the cold, phlegmatic native of the wilderness, gazes upon its display of beautiful mechanism, its majestic march upon its element, and its sublimity of power, with astonishment and admiration. ”

“ The wonderful progress of the present century is, in a very great degree, due to the invention and improvement of the steam-engine, and to the ingenious application of its power to kinds of work that formerly taxed the physical energies of the human race. We cannot examine the methods and processes of any branch of industry without discovering, somewhere, the assistance and support of this wonderful machine. Relieving mankind from manual toil, it has left to the intellect the privilege of directing the power, formerly absorbed in physical labor, into other and more profitable channels. ”

“ The progress of the scientific ideas which led up to the discovery of the power of steam is traced. The claims of the various inventors chiefly associated with the steam engine are set forth in some detail, not for the difficult and invidious task of assessing their relative merits, but because by the light of these claims and altercations it may be possible to discern, in each case, where the merit lay and to what stage each novelty of idea or detail properly belonged. ”

“ It is estimated that the total steam-power of the world is about 15,000,000 horse-power, and that, were horses actually employed to do the work which these engines would be capable of doing were they kept constantly in operation, the number required would exceed 60,000,000.
Thus, from the small beginnings of the Comte d’Auxiron and the Marquis de Jouffroy in France, of Symmington in Great Britain, and of Henry, Rumsey, and Fitch, and of Fulton and Stevens, in the United States, steam-navigation has grown into a great and inestimable aid and blessing to mankind. ”

“ The steam engine to-day is of vastly greater importance than it has ever been before, especially in its use for furnishing the motive power for cotton and woolen factories, and for all kinds of manufacturing establishments. What should we do to-day without the steam engine? Long before the beginning of this century Erasmus Darwin sang as follows:
"Soon shall thy arm, unconquered steam! ”

“ The knowledge then existing of the immense expansive force of steam, and the belief that it was destined to submit to the control of man and to lend its immense power in every department of industry, were evidently not confined to any one nation. ”

“ It is largely in consequence of this ingenious application of a power that reminds one of the fabled genii of Eastern romance, that the mechanic and the laborer of to-day enjoy comforts and luxuries that were denied to wealth, and to royalty itself, a century ago.
The magnitude of our modern steamships excites the wonder and admiration of even the people of our own time ”

“ The modern engine, which now claims our attention, is the result of numerous successive improvements. The application of steam as a motive power was probably originally made by Hero, who, 150 B.C., constructed, or at least described, an Æolipile. This was a hollow sphere with hollow bent arms attached; when water placed inside the sphere was heated, and steam generated, it issued from the arms, and reacting on the air caused the sphere to rotate. A model of this, the primogenitor of the modern steam-engine, can be bought at many opticians’ shops for about one shilling. ”

“ Judging from the rapid strides the steam-engine has made during the last forty years to become a universal first-mover, and from the experience that has arisen from that extension, we feel convinced that every invention which diminishes its size without impairing its power brings it a step nearer to the assistance of the ‘world’s great laborers,’ the husbandman and the peasant, for whom, as yet, it performs but little. ”

“ But there does not seem any reason why steam-power should be less economically convertible to the purpose of propulsion by an internal screw-pump out of the way of risk, than by an external screw-pump, exposed to risk, not only from the enemy’s shot, but from its weak attachment to the vessel and its exposure to fouling any floating substance. ”

“ Now, however, that the applications of steam-power have reached such perfection, this enterprising people have determined upon an enterprise much more gigantic than any they have hitherto attempted, — nothing less than the drainage of the Zuyder-Zee. ”

“ The advantages which the concourse of numerous and variously skilled workmen in all branches offers in large towns where wind and water power are wanting, can be utilised, for steam engines find place everywhere, and supply the necessary crude force; thus the more intelligent human force may be spared for better purposes; and, indeed, wherever the nature of the ground or the neighbourhood of suitable lines of communication present a favourable opportunity for the development of industry, the motive power is also present in the form of steam engines. ”

“ The use of steam as a mechanical power was proposed nearly two hundred years ago by one of the glories of France, the unfortunate Denis Papin, who, after giving the first suggestion of the steam-engine, source of incalculable riches, languished in a foreign land, poverty-stricken and forlorn. ”

“ The power of steam was not entirely unknown to the ancients, but before the æra rendered memorable by the discoveries of James Watt, the steam-engine, which has since become the object of such universal interest, was a machine of extremely limited power, inferior in importance and usefulness to most other mechanical agents used as prime movers. ”

“ The safe and rapid navigation by steamships may be regarded as an entirely new art due to the steam-engine. Already this art has permitted the establishment of prompt and regular communications across the arms of the sea, and on the great rivers of the old and new continents. It has made it possible to traverse savage regions where before we could scarcely penetrate. It has enabled us to carry the fruits of civilization over portions of the globe where they would else have been wanting for years. Steam navigation brings nearer together the most distant nations. ”

“ The power of steam, though marvelously developed by English cleverness, is an auxiliary force belonging of right to the whole human race, as much as gravity or electricity, wherever its service may be called for, and its abode can no more be exclusively monopolized than that of the Promethean fire stolen from Heaven. ”

“ The agent steam possesses great power when confined and properly applied to shafts and wheels. But let the boiler explode and the steam pass into the atmosphere, what power is there then in that agent? ”

“ It lessens the power of time and space, and makes neighbors of ocean-divided continents.
It would not be easy for men living in the twentieth century to imagine a society uninfluenced by the use of steam; but nearly all of man's life on the earth has been passed without its help. Fire and water, the two productive factors of steam, have always existed; but it was not until a few score of years ago that man learned to put them together successfully, and to produce the greatest force known to civilization. ”

“ But on one matter there is hardly any room for doubt, and that is that the best way to secure the benefit of the expansive power of steam is to permit it to escape from a pipe having a long series of orifices and to impinge upon a correspondingly numerous series of vanes, or, perhaps, upon a number of vanes arranged so that each one is long enough to receive the impact of many jets. ”

“ The application of the steam-engine has in modern times almost entirely displaced the use of either water or wind as sources of power in machinery, and most of the saw-mills now in action, especially those on a large scale, are worked by steam. ”

“ Of course the great and leading event of the nineteenth century in the matter of inventions relating to ships was the introduction of steam as the motive power. Of this we have treated in the chapter on steam engineering. The giant, steam, demanded and received the obeisance of every art before devoting his inexhaustible strength to their service. Systems of wood-working and metal manufacture must be revolutionised to give him room to work, and to withstand the strokes of his mighty arm. ”

“ Fire makes steam and what does steam do? Its services are so many you could hardly name all of them. The great and many services of steam are made possible by the fire-engine, or steam-engine, and the story of this wonderful invention will now be told.
FIG. 1.—FIRST EXPERIMENTS WITH STEAM.
That steam has the power to move things must have been learned almost as soon as fire was used to boil water. Heat water until it boils and the steam that is formed is bound to move something unless it is allowed to escape freely. It will burst the vessel if an outlet is not provided. ”

“ The lessons of the early era are worthless for repetition. There is no better screw-propelling machinery known than was then tried and abandoned; but the lessons are of value to discover the difficulties which must be remedied; to teach that the success of steam lies beyond the reach of publicly known mechanical resources.
The trials establish plainly and incontrovertibly that the failures were owing to the want of mechanical adaptation to required duty; to a mechanical inability to utilize the power of the steam; to a mechanical waste of power beyond their ability to control or remedy ”

“ In the first place, there must be some strong material available of which to make the machines; for that purpose iron and steel have, with few exceptions, proved to be the best. In the second place, some adequate power must be found to propel the machinery, which is ordinarily too heavy to be run by hand or foot power. This necessary motive power was discovered in steam. The steam engine was devised by James Watt, an English inventor of great ingenuity. ”

“ But though the capacities of Steam are not half exhausted, we grow dissatisfied with its performance and impatient of its conditions; we demand its power without its weight, its bulk, its cost, its explosive tendencies, or rather those of the elements from which it is evolved—and Electricity, Air, Gunpowder, and other potencies are analyzed and interrogated in quest of the most advantageous substitute—a search which will ultimately achieve success. ”

“ In 1848 he patented an improvement in the method of controlling motive power, by which method steam is applied at the present time to various uses, notable among which is the steering of steam vessels, the steersmen turning the wheel precisely as in steering by hand, but all the force being exerted by the steam. ”

“ Samuel Smiles says, "Many skilful inventors have from time to time added new power to the steam-engine; and by numerous modifications rendered it capable of being applied to nearly all the purposes of manufacture—driving machinery, impelling ships, grinding corn, printing books, stamping money, hammering, planing, and turning iron; in short of performing every description of mechanical labour where power is required. ”

“ The genius of Worcester, and Morland, and Savery, and Desaguliers, had, in the first period of the [145] application of the power of steam to useful work, effected a beginning which, looked upon from a point of view which exhibits its importance as the first step toward the wonderful results to-day familiar to every one, appears in its true light, and entitles those great men to even greater honor than has been accorded them. ”

“ When steam was first applied to the propulsion of ships the common argument against it was that any machine worked by steam and having sufficient power to propel a vessel would also develop so much vibration as to pull her to pieces—to say nothing of the risk of having her hull shattered at one fell blow by the explosion of the steam boiler. ”

“ While this attracted the attention of savants, it had little or no interest for practical men, and yet in it lay the germ of the power that was to revolutionize the world. He went to London with letters to the Royal Society, and was employed by that society several years, during which he continued his experiments on atmospheric pressure and the vacuum, and the power of steam. ”
