40 App. D.C. 29 | D.C. Cir. | 1913
delivered the opinion of the Court:
This is an appeal by Campbell P. Higgins from a decision of the Commissioner of Patents, refusing the following article claims:
“1. As an article of manufacture, a wrought metal water-tube boiler header made of a single plate without seam or weld.
“2. As an article of manufacture, a wrought metal water-*30 tube boiler header longitudinally sinuous and made of a single plate without seam or weld on its sides or ends.”
“5. As an article of manufacture, a wrought metal water-tube boiler header without seam or weld, the material of which consists of a plate transformed into a substantially non-thinned, closed ended, weldless blank, substantially as described.”
The notice of appeal included two process claims; but, as those have been waived by appellant, we omit them here. The application originally contained broad process claims which, being held unpatentable in view of the prior art, appellant was content with the allowance of claims restricted to the particular steps of his process. He had previously, according to the opinion of the Commissioner, been granted patents on the machines by which his process is carried out. He now seeks to patent the boiler header which is the product of his particular process. He claims his header to be superior to those of the prior art and distinguishable from them -because it is made from a single plate, without seam or weld. The utility and superiority of this header over the prior art is not disputed by the Patent Office, but it is nevertheless insisted that appellant was not the first to conceive a seamless boiler header made from one piece of metal. Appellant admits that it was old to cast such boiler headers, and that welded wrought metal headers were also old; but he contends that the conception of producing- a one-piece wrought metal header involved invention. What he has really done is to devise a particular process and machinery by which the seamless single-plate header of the prior art may be produced in wrought metal, and, in doing this, he has had recourse to the patent to Stampacchia (April 5, 1898, No. 601,738), and the patent to Gault (October 30, 1906, No. 834,291). The patent to Stampacchia relates to apparatus for manufacturing closed-ended vessels from single pieces of metal. By this apparatus the original thickness of the metal may be maintained, as in appellant’s, and articles of any desired depth may be obtained by subjecting them to a series of operations in the dies described in the patent. We shall not attempt a critical analysis of the patent, as we do not deem it necessary. It is ob
A single-plate metal boiler header without seam or weld was old. Appellant has perfected a process whereby such a header may be made of wrought metal; in other words, searching the prior art, he found a seamless one-piece, cast header. He found welded wrought metal headers. The superiority of wrought metal over east being apparent, the problem which confronted him was to perfect a process and devise machinery that would enable him to duplicate the cast metal header in wrought metal. The function of the header'produced by him is identical with the cast and wrought headers of the prior art. It does not follow that, because it is superior in point of utility to those preceding it, appellant is entitled to a patent.
