Opinion

KNOWLES, District Judge.

This is an action brought by Farrell and Migeon to recover damages and an accounting and an injunction for the alleged infringement of a certain patent granted by the United States to one Pierre Manhes, the same being No. 470,644, and dated March 8,1892. The patent has two claims, and they are as follows:

,‘T claim as my invention: (1) The process of reducing commercial or pig copper from copper matte, consisting in charging the matte in a molten state into a converter, forcing radial jets of air uniformly and continuously through the charge of molten matte, and causing the heat produced by the combustion of the sulphur and iron in the matte to separate the foreign substance from the metallic copper contained therein, allowing the metallic copper as it is separated from the matte to settle below the action of the air jets, and removing the chilled metallic copper as it forms around and obstructs the inner ends of the tuyéres, and thereby insure the maintenance of a continuous and practically uniform distribution of air throughout the molten matte, and continuing the operation- until the metallic copper contained in the charge has been separated therefrom, and then removing the copper from converter, substantially as set forth. (2) A converter for reducing commercial or pig copper from copper matte, having a wind-belt encircling the converter above its bottom, a series of tuyéres extending through the lining of the converter and communicating. at their outer ends with the wind-belt, and removable stoppers located in the outer walls of the wind-belt and in alignment with each one of said tuyéres, whereby a drift bar may be inserted successively through said tuyéres to remove obstructions from their inner ends, substantially as set forth.”

The complainants claim that both the process above described and the converter used are new and novel; that said Pierre Manhes was the original, first, and sole inventor thereof, and that the same was not known or used by others in this country, and not patented or described in any printed publication in this or any foreign country before his invention or discovery thereof, and which was not in public use or on sale in this country for more than two years prior to his application for letters patent of the United States.

The defendant in its answer denies that said Pierre Manhes was the original, first, and sole inventor of the alleged new and useful improve[842]*842ment in the process for reducing commercial or pig copper from copper matte, and of said alleged new and useful improvement in converters for copper ores, as set forth and described in said letters patent; also denies that said alleged improvements were not known or used by others in this country before the supposed invention thereof by said Manhes; also further denies that said alleged improvements were not patented or described in printed publications in this or any foreign country before the supposed invention and discovery thereof by the said Manhes, as alleged in the bill of complaint; also further denies that said alleged improvements were not in public use or on sale in this country for more than two years prior to the application for said letters patent of the United States therefor; denies infringement; avers a failure of the patentee and the complainants to comply with the requirements of section 4900 of the Revised Statutes of the United States [U. S. Comp. St. 1901, p. 3388] in respect to the marking of their converters in the manner and form as therein prescribed; avers anticipation by prior patents; also avers public use for two years or more; expiration of the patent in suit by reason of the provisions of section 4887 of the Revised Statutes; also sets up the defense of laches. The general replication was filed to this answer, and the record is now before the court.

The first question presented is, was the process specified in Manhes’s patent a new and useful one? As stated in the patent, the process claimed to be new and useful consists: (1) In charging matte in a molten state into a converter; (2) forcing radial jets of air uniformly and continuously through the charge of molten matte; (3) allowing copper, as it is separated from the matte, to settle below the action of the air jets; (4) removing the chilled metallic copper as it forms around and obstructs the inner ends of the tuyeres; (5) .continuing the operation until the metallic copper contained in the charge has been separated therefrom; (6) and then removing the copper from the converter, substantially as set forth.

In the United States patent No. 16,082, granted to Henry Bessemer, November 11, 1856, and entitled “Improvements in the Manufacture of Iron and Steel,” the following statement is made:

“My invention consists in the decarbonization or partial decarbonization and refinement of the crude iron which is obtained in a fluid state from the blast furnaces in which the iron ore is usually smelted, or the decarbonization and refinement of crude pig iron or finery iron, by first smelting the pigs of crude iron or the plates of finery iron in any suitable furnace, so as to obtain fluid metal for the purpose of being treated by my improved means, and which consists, first, in running the fluid iron into a close or nearly close vessel or chamber, formed by preference of iron, and lined with fire bricks or other slow conductor of heat. When the chamber or vessel is about filled, I blow or force into and among the fluid metal numerous small jets of atmospheric air in a cold or in a previously heated state, or I use any other gaseous fluid or matter containing or capable of evolving sufficient oxygen to cause the combustion of the carbon contained in the iron, and thereby to keep up the required temperature during the process. The size or number of the jets or tuySre pipes by which the air or other gaseous matters are conducted into the molten metal should be proportioned to the quantity of fluid metal operated upon at a time, and may also vary with the condition or quality of the metal. * * * When using foundry iron of the quality known as No. 2, I run one ton of it into the converting vessel, in which it rises to a height of about one [843]*843foot above the orifices of the tuySre pipes. I then force into the fluid metal atmospheric air, in its natural or unheated state, under a pressure of about ten pounds per square inch, and I employ from six to twelve tuyere pipes for the distribution of the air, the united area of the tuySres being equal to two square inches.”

In this patent Bessemer also states:

“I have also found that a single outlet In each tuyere block will answer well in practice, as represented in end elevation at Fig. 11, and in longitudinal section at Fig. 12, where a single parallel passage, y, leads direct from the pipe, u, into the metal, as these passages sometimes get obstructed. I fit a screw-plug, q, at the back of the elbow of the pipe, u, which plug may be removed if required, while the apparatus is in use, and a steel rod introduced at the aperture, which should be thrust entirely through the tuySre block, and any accidental accumulation of matter will thus be removed.”

In the United States patent No. 49,052, granted to Bessemer, July-25, 1865, and in the United States Patent No. 51,398, granted to Bessemer, December 5, 1865, the process of converting pig iron into steel by the pneumatic process, the injection of atmospheric air into the molten mass in the converter is especially described and referred to. In the United States patent No.
