The long list of famous patentees with their inventions which a previous chapter contains is an eloquent testimonial to the fact that fame, fortune and an undying place in history will be given to anyone fortunate enough to conceive and work out a new idea which inures to the benefit of mankind. While these famous inventors have been devising and exploiting inventions of wide scope and large calibre there have been an army of small inventors which should be equally as famous and whose inventions will, probably, on the average, return larger proportionate profits to their owners than have a great many of the prominent ones already listed. The writer has in mind small inventions, such as, for instance, Mrs. Pott's Sad Iron; the De Long Hook and Eye; the Gillette Safety Razor; Enterprise Meat Chopper; Junoform Bust Form; Push-point Pencil; Bromo Seltzer; Morrow Coaster Brake; Brass Tips for Boys' Shoes; Mennen's Talcum Powder; Rubber Tips for Lead Pencils; Bundy Time Clock; President Suspenders; Pianola; Castoria; Angelus; O'Sullivan's Rubber Heel; Macey's Sectional Bookcases; Red Dwarf Ink Pencil; 1900 Washing Machine; Tyden Table Lock, and the thousands of similar small inventions, practically all of which are bringing or have brought enormous fortunes to their owners and developers.

King C. Gillette has become a wealthy man from the royalties and profits on his safety razor. While safety razors had been on the market for years, it took Gillette to bring out a better one, patent it, and make his fortune. The inventor of the President Suspender is said to have collected over fifty thousand dollars last year in royalties on the sales of over two hundred thousand dozen pairs of his suspenders. Miss Wolfe, the inventor of the Junoform Bust Form, it was remarked recently, would attain wealth from her royalties. Mrs. Potts is reputed to have collected over half a million dollars from royalties from the patents on her sad iron.

It is also said that the Selden Gas Engine royalties exceed ten million dollars in amount. It is stated that McCormick, the inventor of a Cream Separator, has an annual income from his patents of over thirty thousand dollars. It is said that the inventor of the new-style "pay-as-you-enter" street car will receive a large royalty on every car of that style used in the United States. They are at present coming into use on the metropolitan street car lines. Everybody is familiar with the enormous fortune made by Pullman with his palace car patents.

NOTES.

It is related that when George Westinghouse called on Commodore Vanderbilt to endeavor to interest him in his air-brake, Vanderbilt said to him: "Do you mean to tell me that you can stop a train of cars by wind?" and when informed that in effect that was what was contemplated, remarked that he had no time for fools. Sometime afterward when, through the support of Andrew Carnegie and several others, a successful test of the brake had been made, Westinghouse had the satisfaction, according to the story, of replying to Vanderbilt's request for a conference, "I have no time to waste on fools."

Ottmar Mergenthaler worked twenty years on the development of his linotype machine, and ten years thereafter in perfecting it. The Mergenthaler Linotype Company has paid out twenty millions of dollars in dividends in fourteen years. The romance of the invention of the linotype brings out in glaring letters PERSISTENCE, as Edward Mott Woolley states in "System," of September, 1908, in an article describing the development of the linotype machine.

It is related of Oscar Hammerstein, the well-known theatrical proprietor, that when he was fifteen years old he landed from a steamer at the Battery in New York, after running away from his German home. He was without money or friends, or any place to go. He got a job in a cigar factory at $2.00 per week. Making cigars by hand seemed to him a poor way of doing it, so he began experimenting on his own account, and four years later he had a machine to do the work. He sold this machine for $6,000 cash, and immediately started on a new one, which in place of selling outright he had manufactured on a royalty basis. It is said that he has received over $250,000 in cash from his royalties. Yet today Hammerstein is not known by his inventions, but by the big theatrical enterprises which have earned or lost other fortunes for him at various times.

In the struggle of Charles Goodyear to manufacture a rubber compound that should fulfil mercantile needs is presented a striking, if rather familiar example of what eternal persistence will finally accomplish, and of how it may be assisted by what we call "luck." When he was twenty-one Goodyear entered a rubber house in Philadelphia and began experimenting in India rubber. By chance one day a little rubber mixed with sulphur fell on a stove, and he at once realized what might be accomplished by what is now known as vulcanization. To carry on his experiments he was required to pawn the school-books of his children to raise money. However, he kept everlastingly at it, and was rewarded with a number of international prizes and decorated by several foreign rulers. His name has gone down to fame as one of the successful inventors of the world. The Goodyear Rubber Company bears his name.

The public today is familiar with the record of Thomas A. Edison, who is considered the greatest inventor the world has ever known. The new book which has recently come out, "The Life of Thomas A. Edison," is well worth purchasing and reading. The public press reported he had won his infringement suits and that the "Moving Picture" trust or combination agreed to pay him royalties running into a sum of seven figures.

George Ade, the "funny man," is independent financially from the royalties paid him on his copyrights.

The story of the De Long Hook and Eye Company is the history of an infinitesimal start with an enormous present size.

Sir Henry Bessemer is said to have been paid $10,000,000 in royalties on his steel process.

Emerson, a Baltimore druggist, made a number of fortunes from his invention of Bromo-Seltzer. Likewise Mennen, of talcum powder fame, whose face and name are known all over the world.

Landis, a Franklin county (Pa.) man, sold his "Straw Stacker" patents, it is said, for $50,000 cash,—practically all profit.

This list, if complete, would fill volumes, but it would be a story with the same ending in each and every case.

A careful study of the reason why all the above patents have proved to be so successful emphasizes the fact that inventors, to succeed, must not lose sight of the Six Cardinal Tests enumerated elsewhere in this volume.
