SUGGESTIVE EXTRACTS FROM DR. PERCY’S WORKS ON METALLURGY.
The Copper Trade.
It would be sheer waste of time even to notice many of the mis-called improvements in copper—something for which Patents have been granted in this country during the last twenty years. Some of the patentees display such deplorable ignorance of the first principles of chemistry, and such utter want of practical knowledge, as would seem hardly possible with the present facilities of acquiring information.
Various Patents have been granted for alleged improvements in the treating of copper ores, of certain products obtained in the smelting of copper ores, &c., which are only worthy of notice as affording, as I conceive, satisfactory illustrations of the defective state of our existing Patent-Laws.... That a man who has worked out an original and valuable process from his own brain, and who may have incurred great expenses in bringing it to a practical issue—it may be, after years of protracted toil and anxiety—should have secured to him by law during a moderate term the exclusive privilege of reaping the substantial reward of his own invention, appears to me as just and reasonable as that an author should be protected against piratical and unprincipled publishers. But that the law should confer upon a man the exclusive right of appropriating to his own benefit facts which are perfectly familiar to every tyro in chemistry, and of practising operations which are of daily occurrence in the laboratories of chemists, is as impolitic as it is unjust. And surely, the particular “inventions” above referred to belong to this category. I cordially subscribe to the opinion expressed by Mr. Grove, Q.C.—namely, that the real object of Patent-Law was to reward not trivial inventions, which stop the way to greater improvements, but substantial boons to the public; not changes such as any experimentalist makes a score a day in his laboratory, but substantial, practical discoveries, developed into an available form.
The Hot Blast.
It cannot strictly be termed a great invention, for what great exercise of the inventive faculty could it possibly have required for its development? There was no elaborate working out of a process or machine, as has been the case in many inventions, but the thing was done at once. Without wishing in the smallest degree to detract from the merit to which Mr. Neilson is justly entitled, I may nevertheless express my opinion that the hot-blast was a lucky hit rather than an invention, properly so-called. Whatever opinion may be entertained as to the expediency of Patents, there can be no doubt that such a Patent as this ought never to have been granted. A Patent, even though it may be proved invalid, confers upon its possessor a locus standi in the eye of the law, and enables him thereby to involve innocent persons in most expensive litigation, to say nothing of the attendant annoyance and anxiety. The preliminary examination before the Attorney or Solicitor-General is in many cases an absolute farce, and nothing less. The present system, although confessedly an improvement on the old one, is yet in many cases highly obstructive and injurious to national interests.
The following passage from the Engineer of May 28, proves clearly that the Bessemer Patents do raise prices of iron:—
The present royalty on rails is 2l. per ton; on each ton a drawback of 1l. is nominally allowed, but the nature of Mr. Bessemer’s arrangements with regard to scrap, crop ends, waste, &c., is such that the true royalty on every ton of Bessemer rails delivered to a railway company—in other words, sold—amounts to about 1l. 5s. 6d. After the lapse of Mr. Bessemer’s Patents in February, 1870, this sum, all but 2s. 6d. per ton royalty on plant, will be saved; and, therefore, in March next year, rails may be bought for at least 1l. 3s. per ton less than they cost now.
