The Age of Invention Part 7

The camera bears a large part in the diffusion of intelligence, and the last half century in the United States has seen a great development in photography and photoengraving. The earliest experiments in photography belong almost exclusively to Europe. Morse, as we have seen, introduced the secret to America and interested his friend John W. Draper, who had a part in the perfection of the dry plate and who was one of the first, if not the first, to take a portrait by photography.

The world's greatest inventor in photography is, however, George Eastman, of Rochester. It was in 1888 that Eastman introduced a new camera, which he called by the distinctive name Kodak, and with it the slogan: "You press the b.u.t.ton, we do the rest." This first kodak was loaded with a roll of sensitized paper long enough for a hundred exposures. Sent to the makers, the roll could itself be developed and pictures could be printed from it. Eastman had been an amateur photographer when the fancy was both expensive and tedious. Inventing a method of making dry plates, he began to manufacture them in a small way as early as 1880. After the first kodak, there came others filled with rolls of sensitized nitro-cellulose film. Priority in the invention of the cellulose film, instead of gla.s.s, which has revolutionized photography, has been decided by the courts to belong to the Reverend Hannibal Goodwin, but the honor none the less belongs to Eastman, who independently worked out his process and gave photography to the millions. The introduction by the Eastman Kodak Company of a film cartridge which could be inserted or removed without retiring to a dark room removed the chief difficulty in the way of amateurs, and a camera of some sort, varying in price from a dollar or two to as many hundreds, is today an indispensable part of a vacation equipment.

In the development of the animated pictures Thomas Alva Edison has played a large part. Many were the efforts to give the appearance of movement to pictures before the first real entertainment was staged by Henry Heyl of Philadelphia. Heyl's pictures were on gla.s.s plates fixed in the circ.u.mference of a wheel, and each was brought and held for a part of a second before the lens. This method was obviously too slow and too expensive. Edison with his keen mind approached the difficulty and after a prolonged series of experiments arrived at the decision that a continuous tape-like film would be necessary. He invented the first practical "taking" camera and evoked the enthusiastic cooperation of George Eastman in the production of this tape-like film, and the modern motion picture was born. The projecting machine was substantially like the "taking" camera and was so used. Other inventors, such as Paul in England and Lumiere in France, produced other types of projecting machines, which differed only in mechanical details.

When the motion picture was taken up in earnest in the United States, the world stared in astonishment at the apparent recklessness of the early managers. The public responded, however, and there is hardly a hamlet in the nation where there is not at least one moving-picture house. The most popular actors have been drawn from the speaking stage into the "movies," and many new actors have been developed. In the small town, the picture theater is often a converted storeroom, but in the cities, some of the largest and most attractive theaters have been given over to the pictures, and others even more luxurious have been specially built. The Eastman Company alone manufactures about ten thousand miles of film every month.

Besides affording amus.e.m.e.nt to millions, the moving picture has been turned to instruction. Important news events are shown on the screen, and historical events are preserved for posterity by depositing the films in a vault. What would the historical student not give for a film faithfully portraying the inauguration of George Was.h.i.+ngton! The motion picture has become an important factor in instruction in history and science in the schools and this development is still in its infancy.

CHAPTER VII. THE STORY OF RUBBER

One day in 1852, at Trenton, New Jersey, there appeared in the Circuit Court of the United States two men, the legal giants of their day, to argue the case of Goodyear vs. Day for infringement of patent. Rufus Choate represented the defendant and Daniel Webster the plaintiff.

Webster, in the course of his plea, one of the most brilliant and moving ever uttered by him, paused for a moment, drew from himself the attention of those who were hanging upon his words, and pointed to his client. He would have them look at the man whose cause he pleaded: a man of fifty-two, who looked fifteen years older, sallow, emaciated from disease, due to long privations, bitter disappointments, and wrongs.

This was Charles Goodyear, inventor of the process which put rubber into the service of the world. Said Webster:

"And now is Charles Goodyear the discoverer of this invention of vulcanized rubber? Is he the first man upon whose mind the idea ever flashed, or to whose intelligence the fact ever was disclosed, that by carrying heat to a certain height it would cease to render plastic the India Rubber and begin to harden and metallize it? Is there a man in the world who found out that fact before Charles Goodyear? Who is he? Where is he? On what continent does he live? Who has heard of him? What books treat of him? What man among all the men on earth has seen him, known him, or named him? Yet it is certain that this discovery has been made.

It is certain that it exists. It is certain that it is now a matter of common knowledge all over the civilized world. It is certain that ten or twelve years ago it was not knowledge. It is certain that this curious result has grown into knowledge by somebody's discovery and invention.

And who is that somebody? The question was put to my learned opponent by my learned a.s.sociate. If Charles Goodyear did not make this discovery, who did make it? Who did make it? Why, if our learned opponent had said he should endeavor to prove that some one other than Mr. Goodyear had made this discovery, that would have been very fair. I think the learned gentleman was very wise in not doing so. For I have thought often, in the course of my practice in law, that it was not very advisable to raise a spirit that one could not conveniently lay again. Now who made this discovery? And would it not be proper? I am sure it would. And would it not be manly? I am sure it would. Would not my learned friend and his coadjutor have acted a more n.o.ble part, if they had stood up and said that this invention was not Goodyear's, but it was an invention of such and such a man, in this or that country? On the contrary they do not meet Goodyear's claim by setting up a distinct claim of anybody else. They attempt to prove that he was not the inventor by little shreds and patches of testimony. Here a little bit of sulphur, and there a little parcel of lead; here a little degree of heat, a little hotter than would warm a man's hands, and in which a man could live for ten minutes or a quarter of an hour; and yet they never seem to come to the point. I think it is because their materials did not allow them to come to the manly a.s.sertion that somebody else did make this invention, giving to that somebody a local habitation and a name. We want to know the name, and the habitation, and the location of the man upon the face of this globe, who invented vulcanized rubber, if it be not he, who now sits before us.

"Well there are birds which fly in the air, seldom lighting, but often hovering. Now I think this is a question not to be hovered over, not to be brooded over, and not to be dealt with as an infinitesimal quant.i.ty of small things. It is a case calling for a manly admission and a manly defense. I ask again, if there is anybody else than Goodyear who made this invention, who is he? Is the discovery so plain that it might have come about by accident? It is likely to work important changes in the arts everywhere. IT INTRODUCES QUITE A NEW MATERIAL INTO THE MANUFACTURE OF THE ARTS, THAT MATERIAL BEING NOTHING LESS THAN ELASTIC METAL. It is hard like metal and as elastic as pure original gum elastic. Why, that is as great and momentous a phenomenon occurring to men in the progress of their knowledge, as it would be for a man to show that iron and gold could remain iron and gold and yet become elastic like India Rubber. It would be just such another result. Now, this fact cannot be denied; it cannot be secreted; it cannot be kept out of sight; somebody has made this invention. That is certain. Who is he? Mr. Hanc.o.c.k has been referred to. But he expressly acknowledges Goodyear to be the first inventor. I say that there is not in the world a human being that can stand up and say that it is his invention, except the man who is sitting at that table."

The court found for the plaintiff, and this decision established for all time the claim of the American, Charles Goodyear, to be the sole inventor of vulcanized rubber.

This trial may be said to be the dramatic climax in the story of rubber.

It celebrated the hour when the science of invention turned a raw product--which had tantalized by its promise and wrought ruin by its treachery--into a manufacture adaptable to a thousand uses, adding to man's ease and health and to the locomotion, construction, and communication of modern life.

When Columbus revisited Hayti on his second voyage, he observed some natives playing with a ball. Now, ball games are the oldest sport known.

From the beginning of his history man, like the kitten and the puppy, has delighted to play with the round thing that rolls. The men who came with Columbus to conquer the Indies had brought their Castilian wind-b.a.l.l.s to play with in idle hours. But at once they found that the b.a.l.l.s of Hayti were incomparably superior toys; they bounced better.

These high bouncing b.a.l.l.s were made, so they learned, from a milky fluid of the consistency of honey which the natives procured by tapping certain trees and then cured over the smoke of palm nuts. A discovery which improved the delights of ball games was noteworthy.

The old Spanish historian, Herrera, gravely transcribed in his pages all that the governors of Hayti reported about the bouncing b.a.l.l.s. Some fifty years later another Spanish historian related that the natives of the Amazon valley made shoes of this gum; and that Spanish soldiers spread their cloaks with it to keep out the rain. Many years later still, in 1736, a French astronomer, who was sent by his government to Peru to measure an arc of the meridian, brought home samples of the gum and reported that the natives make lights of it, "which burn without a wick and are very bright," and "shoes of it which are waterproof, and when smoked they have the appearance of leather. They also make pear-shaped bottles on the necks of which they fasten wooden tubes.

Pressure on the bottle sends the liquid squirting out of the tube, so they resemble syringes." Their name for the fluid, he added, was "cachuchu"--caoutchouc, we now write it. Evidently the samples filled no important need at the time, for we hear no more of the gum until thirty-four years afterward. Then, so an English writer tells us, a use was found for the gum--and a name. A stationer accidentally discovered that it would erase pencil marks, And, as it came from the Indies and rubbed, of course it was "India rubber."

About the year 1820 American merchantmen, plying between Brazil and New England, sometimes carried rubber as ballast on the home voyage and dumped it on the wharves at Boston. One of the s.h.i.+pmasters exhibited to his friends a pair of native shoes fancifully gilded. Another, with more foresight, brought home five hundred pairs, ungilded, and offered them for sale. They were thick, clumsily shaped, and heavy, but they sold.

There was a demand for more. In a few years half a million pairs were being imported annually. New England manufacturers bid against one another along the wharves for the gum which had been used as ballast and began to make rubber shoes.

European vessels had also carried rubber home; and experiments were being made with it in France and Britain. A Frenchman manufactured suspenders by cutting a native bottle into fine threads and running them through a narrow cloth web. And Macintosh, a chemist of Glasgow, inserted rubber treated with naphtha between thin pieces of cloth and evolved the garment that still bears his name.

At first the new business in rubber yielded profits. The cost of the raw material was infinitesimal; and there was a demand for the finished articles. In Roxbury, Ma.s.sachusetts, a firm manufacturing patent leather treated raw rubber with turpentine and lampblack and spread it on cloth, in an effort to produce a waterproof leather. The process appeared to be a complete success, and a large capital was employed to make handsome shoes and clothing out of the new product and in opening shops in the large cities for their sale. Merchants throughout the country placed orders for these goods, which, as it happened, were made and s.h.i.+pped in winter.

But, when summer came, the huge profits of the manufacturers literally melted away, for the beautiful garments decomposed in the heat; and loads of them, melting and running together, were being returned to the factory. And they filled Roxbury with such noisome odors that they had to be taken out at dead of night and buried deep in the earth.

And not only did these rubber garments melt in the heat. It presently transpired that severe frost stiffened them to the rigidity of granite.

Daniel Webster had had some experience in this matter himself. "A friend in New York," he said, "sent me a very fine cloak of India Rubber, and a hat of the same material. I did not succeed very well with them. I took the cloak one day and set it out in the cold. It stood very well by itself. I surmounted it with the hat, and many persons pa.s.sing by supposed they saw, standing by the porch, the Farmer of Marshfield."

It was in the year 1834, shortly after the Roxbury manufacturers had come to realize that their process was worthless and that their great fortune was only a mirage, and just before these facts became generally known, that Charles Goodyear made his entrance on the scene. He appeared first as a customer in the company's store in New York and bought a rubber life-preserver. When he returned some weeks later with a plan for improving the tube, the manager confided to him the sad tragedy of rubber, pointing out that no improvement in the manufactured articles would meet the difficulty, but that fame and fortune awaited the inventor of a process that would keep rubber dry and firm and flexible in all weathers.

Goodyear felt that he had a call from G.o.d. "He who directs the operations of the mind," he wrote at a later date, "can turn it to the development of the properties of Nature in his own way, and at the time when they are specially needed. The creature imagines he is executing some plan of his own, while he is simply an instrument in the hands of his Maker for executing the divine purposes of beneficence to the race."

It was in the spirit of a crusader, consecrated to a particular service, that this man took up the problem of rubber. The words quoted are a fitting preface for the story of the years that followed, which is a tale of endurance and persistent activity under sufferings and disappointments such as are scarcely paralleled even in the pages of invention, darkened as they often are by poverty and defeat.

Charles Goodyear was born at New Haven, December 29, 1800, the son of Amasa Goodyear and descendant of Stephen Goodyear who was a.s.sociated with Theophilus Eaton, the first governor of the Puritan colony of New Haven. It was natural that Charles should turn his mind to invention, as he did even when a boy; for his father, a pioneer in the manufacture of American hardware, was the inventor of a steel hayfork which replaced the heavy iron fork of prior days and lightened and expedited the labor of the fields. When Charles was seven his father moved to Naugatuck and manufactured the first pearl b.u.t.tons made in America; during the War of 1812 the Goodyear factory supplied metal b.u.t.tons to the Government.

Charles, a studious, serious boy, was the close companion of his father.

His deeply religious nature manifested itself early, and he joined the Congregational Church when he was sixteen. It was at first his intention to enter the ministry, which seemed to him to offer the most useful career of service, but, changing his mind, he went to Philadelphia to learn the hardware business and on coming of age was admitted to partners.h.i.+p in a firm established there by his father. The firm prospered for a time, but an injudicious extension of credit led to its suspension. So it happened that Goodyear in 1834, when he became interested in rubber, was an insolvent debtor, liable, under the laws of the time, to imprisonment. Soon afterward, indeed, he was lodged in the Debtor's Prison in Philadelphia.

It would seem an inauspicious hour to begin a search which might lead him on in poverty for years and end nowhere. But, having seen the need for perfect rubber, the thought had come to him, with the force of a religious conviction, that "an object so desirable and so important, and so necessary to man's comfort, as the making of gum-elastic available to his use, was most certainly placed within his reach."

Thereafter he never doubted that G.o.d had called him to this task and that his efforts would be crowned with success. Concerning his prison experiences, of which the first was not to be the last, he says that "notwithstanding the mortification attending such a trial," if the prisoner has a real aim "for which to live and hope over he may add firmness to hope, and derive lasting advantage by having proved to himself that, with a clear conscience and a high purpose, a man may be as happy within prison walls as in any other (even the most fortunate) circ.u.mstances in life." With this spirit he met every reverse throughout the ten hard years that followed.

Luckily, as he says, his first experiments required no expensive equipment. Fingers were the best tools for working the gum. The prison officials allowed him a bench and a marble slab, a friend procured him a few dollars' worth of gum, which sold then at five cents a pound, and his wife contributed her rolling pin. That was the beginning.

For a time he believed that, by mixing the raw gum with magnesia and boiling it in lime, he had overcome the stickiness which was the inherent difficulty. He made some sheets of white rubber which were exhibited, and also some articles for sale. His hopes were dashed when he found that weak acid, such as apple juice or vinegar, destroyed his new product. Then in 1836 he found that the application of aqua fortis, or nitric acid, produced a "curing" effect on the rubber and thought that he had discovered the secret. Finding a partner with capital, he leased an abandoned rubber factory on Staten Island. But his partner's fortune was swept away in the panic of 1837, leaving Goodyear again an insolvent debtor. Later he found another partner and went to manufacturing in the deserted plant at Roxbury, with an order from the Government for a large number of mail bags. This order was given wide publicity and it aroused the interest of manufacturers throughout the country. But by the time the goods were ready for delivery the first bags made had rotted from their handles. Only the surface of the rubber had been "cured."

This failure was the last straw, as far as Goodyear's friends were concerned. Only his patient and devoted wife stood by him; she had labored, known want, seen her children go hungry to school, but she seems never to have reproached her husband nor to have doubted his ultimate success. The gentleness and tenderness of his deportment in the home made his family cling to him with deep affection and bear willingly any sacrifice for his sake; though his successive failures generally meant a return of the inventor to the debtor's prison and the casting of his family upon charity.

The nitric acid process had not solved the problem but it had been a real step forward. It was in the year 1839, by an accident, that he discovered the true process of vulcanization which cured not the surface alone but the whole ma.s.s. He was trying to harden the gum by boiling it with sulphur on his wife's cookstove when he let fall a lump of it on the red hot iron top. It vulcanized instantly. This was an accident which only Goodyear could have interpreted. And it was the last. The strange substance from the jungles of the tropics had been mastered.

It remained, however, to perfect the process, to ascertain the accurate formula and the exact degree of heat. The Goodyears were so poor during these years that they received at any time a barrel of flour from a neighbor thankfully. There is a tradition that on one occasion, when Goodyear desired to cross between Staten Island and New York, he had to give his umbrella to the ferry master as security for his fare, and that the name of the ferry master was Cornelius Vanderbilt, "a man who made much money because he took few chances." The incident may easily have occurred, though the ferry master could hardly have been Vanderbilt himself, unless it had been at an earlier date. Another tradition says that one of Goodyear's neighbors described him to an inquisitive stranger thus: "You will know him when you see him; he has on an India rubber cap, stock, coat, vest, and shoes, and an India rubber purse WITHOUT A CENT IN IT!"

Goodyear's trials were only beginning. He had the secret at last, but n.o.body would believe him. He had worn out even the most sanguine of his friends. "That such indifference to this discovery, and many incidents attending it, could have existed in an intelligent and benevolent community," wrote Goodyear later, "can only be accounted for by existing circ.u.mstances in that community The great losses that had been sustained in the manufacture of gum-elastic: the length of time the inventor had spent in what appeared to them to be entirely fruitless efforts to accomplish anything with it; added to his recent misfortunes and disappointments, all conspired, with his utter dest.i.tution, to produce a state of things as unfavorable to the promulgation of the discovery as can well be imagined. He, however, felt in duty bound to beg in earnest, if need be, sooner than that the discovery should be lost to the world and to himself.... How he subsisted at this period charity alone can tell, for it is as well to call things by their right names; and it is little else than charity when the lender looks upon what he parts with as a gift. The p.a.w.ning or selling some relic of better days or some article of necessity was a frequent expedient. His library had long since disappeared, but shortly after the discovery of this process, he collected and sold at auction the schoolbooks of his children, which brought him the trifling sum of five dollars; small as the amount was, it enabled him to proceed. At this step he did not hesitate. The occasion, and the certainty of success, warranted the measure which, in other circ.u.mstances, would have been sacrilege."

His itinerary during those years is eloquent. Wherever there was a man, who had either a grain of faith in rubber or a little charity for a frail and penniless monomaniac, thither Goodyear made his way. The goal might be an attic room or shed to live in rent free, or a few dollars for a barrel of flour for the family and a barrel of rubber for himself, or permission to use a factory's ovens after hours and to hang his rubber over the steam valves while work went on. From Woburn in 1839, the year of his great discovery, he went to Lynn, from Lynn back to the deserted factory at Roxbury. Again to Woburn, to Boston, to Northampton, to Springfield, to Naugatuck; in five years as many removes. When he lacked boat or railway fare, and he generally did, he walked through winds and rains and drifting snow, begging shelter at some cottage or farm where a window lamp gleamed kindly.

Goodyear took out his patent in 1844. The process he invented has been changed little, if at all, from that day to this. He also invented the perfect India rubber cloth by mixing fiber with the gum a discovery he considered rightly as secondary in importance only to vulcanization.

When he died in 1860 he had taken out sixty patents on rubber manufactures. He had seen his invention applied to several hundred uses, giving employment to sixty thousand persons, producing annually eight million dollars' worth of merchandise--numbers which would form but a fraction of the rubber statistics of today.

Everybody, the whole civilized world round, uses rubber in one form or another. And rubber makes a belt around the world in its natural as well as in its manufactured form. The rubber-bearing zone winds north and south of the equator through both hemispheres. In South America rubber is the latex of certain trees, in Africa of trees and vines. The best "wild" rubber still comes from Para in Brazil. It is gathered and prepared for s.h.i.+pment there today by the same methods the natives used four hundred years ago. The natives in their canoes follow the watercourses into the jungles. They cut V-shaped or spiral incisions in the trunks of the trees that grow sheer to sixty feet before spreading their shade. At the base of the incisions they affix small clay cups, like swallows' nests. Over the route they return later with large gourds in which they collect the fluid from the clay cups. The filled gourds they carry to their village of gra.s.s huts and there they build their smoky fires of oily palm nuts. Dipping paddles into the fluid gum they turn and harden it, a coating at a time, in the smoke. The rubber "biscuit" is cut from the paddle with a wet knife when the desired thickness has been attained.

Goodyear lived for sixteen years after his discovery of the vulcanization process. During the last six he was unable to walk without crutches. He was indifferent to money. To make his discoveries of still greater service to mankind was his whole aim. It was others who made fortunes out of his inventions. Goodyear died a poor man.

In his book, a copy of which was printed on gumelastic sheets and bound in hard rubber carved, he summed up his philosophy in this statement: "The writer is not disposed to repine and say that he has planted and others have gathered the fruits. The advantages of a career in life should not be estimated exclusively by the standard of dollars and cents, as it is too often done. Man has just cause for regret when he sows and no one reaps."

CHAPTER VIII. PIONEERS OF THE MACHINE SHOP

There is a tinge of melancholy about the life of such a pioneer as Oliver Evans, that early American mechanic of great genius, whose story is briefly outlined in a preceding chapter. Here was a man of imagination and sensibility, as well as practical power; conferring great benefits on his countrymen, yet in chronic poverty; derided by his neighbors, robbed by his beneficiaries; his property, the fruit of his brain and toil, in the end malevolently destroyed. The lot of the man who sees far ahead of his time, and endeavors to lead his fellows in ways for which they are not prepared, has always been hard.

John Stevens, too, as we have seen, met defeat when he tried to thrust a steam railroad on a country that was not yet ready for it. His mechanical conceptions were not marked by genius equal to that of Evans, but they were still too far advanced to be popular. The career of Stevens, however, presents a remarkable contrast to that of Evans in other respects. Evans was born poor (in Delaware, 1755) and remained poor all his life. Stevens was born rich (in New York City, 1749) and remained rich all his life. Of the family of Evans nothing is known either before or after him. Stevens, on the contrary, belonged to one of the best known and most powerful families in America. His grandfather, John Stevens I, came from England in 1699 and made himself a lawyer and a great landowner. His father, John Stevens II, was a member from New Jersey of the Continental Congress and presided at the New Jersey Convention which ratified the Const.i.tution.

John Stevens III was graduated at King's College (Columbia) in 1768. He held public offices during the Revolution. To him, perhaps more than to any other man, is due the Patent Act of 1790, for the protection of American inventors, for that law was the result of a pet.i.tion which he made to Congress and which, being referred to a committee, was favorably reported. Thus we may regard John Stevens as the father of the American patent law.

John Stevens owned the old Dutch farm on the Hudson on which the city of Hoboken now stands. The place had been in possession of the Bayard family, but William Bayard, who lived there at the time of the Revolution, was a Loyalist, and his house on Castle Point was burned down and his estate confiscated. After the Revolution Stevens acquired the property. He laid it out as a town in 1804, made it his summer residence, and established there the machine shops in which he and his sons carried on their mechanical experiments.

These shops were easily the largest and bestequipped in the Union when in 1838 John Stevens died at the age of ninety. The four brothers, John c.o.x, Robert Livingston, James Alexander, and Edwin Augustus, worked harmoniously together. "No one ever heard of any quarrel or dissension in the Stevens family. They were workmen themselves, and they were superior to their subordinates because they were better engineers and better men of business than any other folk who up to that time had undertaken the business of transportation in the United States."*
