The Age of Invention by Holland Thompson (best e book reader android .txt) 📕

“What is the use of a newborn child?” was the retort.

A newborn child, a newborn republic, a new invention: alike dim beginnings of development which none could foretell. The year that saw the world acknowledge a new nation, freed of its ancient political bonds, saw also the first successful attempt to break the supposed bonds that held men down to the ground. Though the invention of the balloon was only five months old, there were already two types on exhibition: the original Montgolfier, or fireballoon, inflated with hot air, and a modification by Charles, inflated with hydrogen gas. The mass of the French people did not regard these balloons with Franklin’s serenity.

Some weeks earlier the danger of attack had necessitated a balloon’s removal from the place of its first moorings to the Champ de Mars at dead of night. Preceded by flaming torches, with soldiers marching on either side and guards in front and rear, the great ball was borne through the darkened streets. The midnight cabby along the route stopped his nag, or tumbled from sleep on his box, to kneel on the pavement and cross himself against the evil that might be in that strange monster. The fear of the people was so great that the Government saw fit to issue a proclamation, explaining the invention. Any one seeing such a globe, like the moon in an eclipse, so read the proclamation, should be aware that it is only a bag made of taffeta or light canvas covered with paper and “cannot possibly cause any harm and which will some day prove serviceable to the wants of society.”

Franklin wrote a description of the Montgolfier balloon to Sir Joseph Banks, President of the Royal Society of London: “Its bottom was open and in the middle of the opening was fixed a kind of basket grate, in which faggots and sheaves of straw were burnt. The air, rarefied in passing through this flame, rose in the balloon, swelled out its sides, and filled it. The persons, who were placed in the gallery made of wicker and attached to the outside near the bottom, had each of them a port through which they could pass sheaves of straw into the grate to keep up the flame and thereby keep the balloon full … . One of these courageous philosophers, the Marquis d’Arlandes, did me the honor to call upon me in the evening after the experiment, with Mr.

Montgolfier, the very ingenious inventor. I was happy to see him safe. He informed me that they lit gently, without the least shock, and the balloon was very little damaged.”

Franklin writes that the competition between Montgolfier and Charles has already resulted in progress in the construction and management of the balloon. He sees it as a discovery of great importance, one that “may possibly give a new turn to human affairs. Convincing sovereigns of the folly of war may perhaps be one effect of it, since it will be impracticable for the most potent of them to guard his dominions.” The prophecy may yet be fulfilled. Franklin remarks that a short while ago the idea of “witches riding through the air upon a broomstick and that of philosophers upon a bag of smoke would have appeared equally impossible and ridiculous.” Yet in the space of a few months he has seen the philosopher on his smoke bag, if not the witch on her broom. He wishes that one of these very ingenious inventors would immediately devise means of direction for the balloon, a rudder to steer it; because the malady from which he is suffering is always increased by a jolting drive in a fourwheeler and he would gladly avail himself of an easier way of locomotion.

The vision of man on the wing did not, of course, begin .with the invention of the balloon. Perhaps the dream of flying man came first to some primitive poet of the Stone Age, as he watched, fearfully, the gyrations of the winged creatures of the air; even as in a later age it came to Langley and Maxim, who studied the wing motions of birds and insects, not in fear but in the light and confidence of advancing science.

Crudely outlined by some ancient Egyptian sculptor, a winged human figure broods upon the tomb of Rameses III. In the Hebrew parable of Genesis winged cherubim guarded the gates of Paradise against the man and woman who had stifled aspiration with sin.

Fairies, witches, and magicians ride the wind in the legends and folklore of all peoples. The Greeks had gods and goddesses many; and one of these Greek art represents as moving earthward on great spreading pinions. Victory came by the air. When Demetrius, King of Macedonia, set up the Winged Victory of Samothrace to commemorate the naval triumph of the Greeks over the ships of Egypt, Greek art poetically foreshadowed the relation of the air service to the fleet in our own day.

Man has always dreamed of flight; but when did men first actually fly? We smile at the story of Daedalus, the Greek architect, and his son, Icarus, who made themselves wings and flew from the realm of their foes; and the tale of Simon, the magician, who pestered the early Christian Church by exhibitions of flight into the air amid smoke and flame in mockery of the ascension. But do the many tales of sorcerers in the Middle Ages, who rose from the ground with their cloaks apparently filled with wind, to awe the rabble, suggest that they had deduced the principle of the aerostat from watching the action of smoke as did the Montgolfiers hundreds of years later? At all events one of these alleged exhibitions about the year 800 inspired the good Bishop Agobard of Lyons to write a book against superstition, in which he proved conclusively that it was impossible for human beings to rise through the air. Later, Roger Bacon and Leonardo da Vinci, each in his turn ruminated in manuscript upon the subject of flight. Bacon, the scientist, put forward a theory of thin copper globes filled with liquid fire, which would soar. Leonardo, artist, studied the wings of birds. The Jesuit Francisco Lana, in 1670, working on Bacon’s theory sketched an airship made of four copper balls with a skiff attached; this machine was to soar by means of the lighter-than-air globes and to be navigated aloft by oars and sails.

But while philosophers in their libraries were designing airships on paper and propounding their theories, venturesome men, “crawling, but pestered with the thought of wings,” were making pinions of various fabrics and trying them upon the wind. Four years after Lana suggested his airship with balls and oars, Besnier, a French locksmith, made a flying machine of four collapsible planes like book covers suspended on rods. With a rod over each shoulder, and moving the two front planes with his arms and the two back ones by his feet, Besnier gave exhibitions of gliding from a height to the earth. But his machine could not soar. What may be called the first patent on a flying machine was recorded in 1709 when Bartholomeo de Gusmao, a friar, appeared before the King of Portugal to announce that he had invented a flying machine and to request an order prohibiting other men from making anything of the sort. The King decreed pain of death to all infringers; and to assist the enterprising monk in improving his machine, he appointed him first professor of mathematics in the University of Coimbra with a fat stipend. Then the Inquisition stepped in. The inventor’s suave reply, to the effect that to show men how to soar to Heaven was an essentially religious act, availed him nothing. He was pronounced a sorcerer, his machine was destroyed, and he was imprisoned till his death.

Many other men fashioned unto themselves wings; but, though some of them might glide earthward, none could rise upon the wind.

While the principle by which the balloon, father of the dirigible, soars and floats could be deduced by men of natural powers of observation and little science from the action of clouds and smoke, the airplane, the Winged Victory of our day, waited upon two things—the scientific analysis of the anatomy of bird wings and the internal combustion engine.

These two things necessary to convert man into a rival of the albatross did not come at once and together. Not the dream of flying but the need for quantity and speed in production to take care of the wants of a modern civilization compelled the invention of the internal combustion engine. Before it appeared in the realm of mechanics, experimenters were applying in the construction of flying models the knowledge supplied by Cayley in 1796, who made an instrument of whalebone, corks, and feathers, which by the action of two screws of quill feathers, rotating in opposite directions, would rise to the ceiling; and the full revelation of the structure and action of bird wings set forth by Pettigrew in 1867.

“The wing, both when at rest and when in motion,” Pettigrew declared, “may not inaptly be compared to the blade of an ordinary screw propeller as employed in navigation. Thus the general outline of the wing corresponds closely with the outline of the propeller, and the track described by the wing in space IS

TWISTED UPON ITSELF propeller fashion.” Numerous attempts to apply the newly discovered principles to artificial birds failed, yet came so close to success that they fed instead of killing the hope that a solution of the problem would one day ere long be reached.

“Nature has solved it, and why not man?”

From his boyhood days Samuel Pierpont Langley, so he tells us, had asked himself that question, which he was later to answer.

Langley, born in Roxbury, Massachusetts, in 1834, was another link in the chain of distinguished inventors who first saw the light of day in Puritan New England. And, like many of those other inventors, he numbered among his ancestors for generations two types of men—on the one hand, a line of skilled artisans and mechanics; on the other, the most intellectual men of their time such as clergymen and schoolmasters, one of them being Increase Mather. We see in Langley, as in some of his brother New England inventors, the later flowering of the Puritan ideal stripped of its husk of superstition and harshness—a high sense of duty and of integrity, an intense conviction that the reason for a man’s life here is that he may give service, a reserved deportment which did not mask from discerning eyes the man’s gentle qualities of heart and his keen love of beauty in art and Nature.

Langley first chose as his profession civil engineering and architecture and the years between 1857 and 1864 were chiefly spent in prosecuting these callings in St. Louis and Chicago.

Then he abandoned them; for the bent of his mind was definitely towards scientific inquiry. In 1867 he was appointed director of the Allegheny Observatory at Pittsburgh. Here he remained until 1887, when, having made for himself a world-wide reputation as an astronomer, he became Secretary of the Smithsonian Institution at Washington.

It was about this time that he began his experiments in “aerodynamics.” But the problem of flight had long been a subject of interested speculation with him. Ten years later he wrote: “Nature has made her flying-machine in the bird, which is nearly a thousand times as heavy as the air its bulk displaces, and only those who have tried to rival it know how inimitable her work is, for the “way of a bird in the air” remains as wonderful to us as it was to Solomon, and the sight of the bird has constantly held this wonder before men’s minds, and kept the flame of hope from utter extinction, in
