On the 8th of December following, Mr. Koenig addressed an advertisement "To the Public" in the columns of The Times, giving an account of the origin and progress of his invention. We have already cited several passages from the statement. After referring to his two last patents, he says: "The machines now printing The Times and Mail are upon the same principle; but they have been contrived for the particular purpose of a newspaper of extensive circulation, where expedition is the great object.

"The public are undoubtedly aware, that never, perhaps, was a new invention put to so severe a trial as the present one, by being used on its first public introduction for the printing of newspapers, and will, I trust, be indulgent with respect to the many defects in the performance, though none of them are inherent in the principle of the machine; and we hope, that in less than two months, the whole will be corrected by greater adroitness in the management of it, so far at least as the hurry of newspaper printing will at all admit.

"It will appear from the foregoing narrative, that it was incorrectly stated in several newspapers, that I had sold my interest to two other foreigners; my partners in this enterprise being at present two Englishmen, Mr. Bensley and Mr. Taylor; and it is gratifying to my feelings to avail myself of this opportunity to thank those gentlemen publicly for the confidence which they have reposed in me, for the aid of their practical skill, and for the persevering support which they have afforded me in long and very expensive experiments; thus risking their fortunes in the prosecution of my invention.

"The first introduction of the invention was considered by some as a difficult and even hazardous step. The Proprietor of The Times having made that his task, the public are aware that it is in good hands."

One would think that Koenig would now feel himself in smooth water, and receive a share of the good fortune which he had so laboriously prepared for others. Nothing of the kind! His merits were disputed; his rights were denied; his patents were infringed; and he never received any solid advantages for his invention, until he left the country and took refuge in Germany. It is true, he remained for a few years longer, in charge of the manufactory in Whitecross Street, but they were years to him of trouble and sorrow.

In 1816, Koenig designed and superintended the construction of a single cylinder registering machine for book-printing. This was supplied to Bensley and Son, and turned out 1000 sheets, printed on both sides, in the hour. Blumenbach's 'Physiology' was the first entire book printed by steam, by this new machine. It was afterwards employed, in 1818, in working off the Literary Gazette. A machine of the same kind was supplied to Mr. Richard Taylor for the purpose of printing the 'Philosophical Magazine,' and books generally. This was afterwards altered to a double machine, and employed for printing the Weekly Dispatch.

But what about Koenig's patents? They proved of little use to him. They only proclaimed his methods, and enabled other ingenious mechanics to borrow his adaptations. Now that he had succeeded in making machines that would work, the way was clear for everybody else to follow his footsteps. It had taken him more than six years to invent and construct a successful steam printing press; but any clever mechanic, by merely studying his specification, and examining his machine at work, might arrive at the same results in less than a week.

The patents did not protect him. New specifications, embodying some modification or alteration in detail, were lodged by other inventors and new patents taken out. New printing machines were constructed in defiance of his supposed legal rights; and he found himself stripped of the reward that he had been labouring for during so many long and toilsome years. He could not go to law, and increase his own vexation and loss. He might get into Chancery easy enough; but when would he get out of it, and in what condition?

It must also be added, that Koenig was unfortunate in his partner Bensley. While the inventor was taking steps to push the sale of his book-printing machines among the London printers, Bensley, who was himself a book-printer, was hindering him in every way in his negotiations. Koenig was of opinion that Bensley wished to retain the exclusive advantage which the possession of his registering book machine gave him over the other printers, by enabling him to print more quickly and correctly than they could, and thus give him an advantage over them in his printing contracts.

When Koenig, in despair at his position, consulted counsel as to the infringement of his patent, he was told that he might institute proceedings with the best prospect of success; but to this end a perfect agreement by the partners was essential. When, however, Koenig asked Bensley to concur with him in taking proceedings in defence of the patent right, the latter positively refused to do so. Indeed, Koenig was under the impression that his partner had even entered into an arrangement with the infringers of the patent to share with them the proceeds of their piracy.
