APPEAL PROM THE CIRCUIT COURT OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF NEW YORK.delivered the opinion of tjie court.
This suit was brought in the Circuit Court of the United States for the Southern District of New York, on letters patent No. 122,001-, granted to the plaintiff, The Eagleton Manufacturing Company, December 19th, 1871, for an “ improvement in japanned furniture springs.” The patent contains these recitals: “Whereas J. J. Eagleton of New York, New York (Sarah N. Eagleton, administratrix), has presented, to the Commissioner of Patents a petition praying for the grant of letters patent for an alleged new and useful improvement in japanned furniture springs (she having assigned her right, title and interest in said improvement, as administratrix, to.Eagleton Manufacturing Company, of same place), a description of which invention is contained in the specification of which a copy is hereto annexed and made a part hereof, and has complied with the various requirements of law in such cases made and provided; and whereas, upon due examination' made, the said claimant is adjudged to be justly entitled to a patent under the law.” "The specification of the patent is as follows:.
“Be it known, that I, J. Joseph Eagleton, of New York, in the county of New York,- and State of New York, have invented a new and useful improvement in furniture springs ; and I do hereby
declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which the drawing represents a furniture spring provided, according to my improvement, with a japan covering. [The helical springs heretofore employed for furniture-seats, mattresses, &c., have generally been made of iron wire, brass, or copper ; but steel wire, although a far superior material for such springs, has not been commonly employed, owing
to the lack of means for protecting such springs from corrosion and the lack of means for imparting to them the necessary stiffness or temper. The object of this invention is to produce steel furniture springs that shall not only be protected from corrosion, but shall also be suitably tempered and stiffened. The drawing is a perspective view of one of my improved springs. In carrying out my invention, I provide a suitable quantity of steel wire of the size of which the spring is to be made, and this I wind upon blocks in the usual manner, giving the wound spring the ordinary pressing or set. I then provide a suitable bath containing the ordinary preparation of japan varnish, in which I dip or place the springs, so as to cover them with japan.. They are then removed and strung on wires, or put on pegs, to drain, after which they are placed in a baking oven of the ordinary kind suitable for the baking of japanned articles, in which oven the springs are subjected to a temperature sufficient to bake and harden the japan ; after which the springs are removed from the oven and allowed to cool, when they are ready for use. The treatment of the springs in this manner imparts to them two important and valuable qualities : First, the springs, when they come from the oven and are cooled, have firmly attached to their exterior surface a water-proof covering or coating, which perfectly protects them from corrosion and fits them for service in all kinds of climates, hot or cold, dry or damp. Second, the spirings thus propiared are strengthened or stiffened, the application of heat to the springs in the oven having the apparent effect to tempen the steel of which they are composed, making the springs stronger and more elastic. As between a steel spring not japanned, as I have described, and a steel spring japanned, as described, both being of the same size and made from the same piece of wire, the japanned spring will be found to be much stronger than the spring not japanned. The spring not japanned is, therefore, not only lacking in strength, but it is also practically useless, for want of a protecting covering. But the improved article, produced substantially in the manner I have described, forms a strong and durable spring, and no article like it has, so far as I am aware, ever been known or used. While I do not claim broadly, the making, of furniture springs of steel wire, I wish it to be understood I do not limit or confine myself to the exact order or method of operation here described, in producing my im
proved springs, as the order or method may be varied without departing from my invention.”]
There are two claims, namely: “ 1. The method, herein- described, of strengthening metal springs. 2. As an improved article of manufacture, a spring made substantially as herein described.”
Eagleton, as inventor, filed in the Patent Office, on the 6th of July, 1868, a petition for a patent for an “ improvement in furniture springs,” accompanied by an affidavit, a specification, a drawing, and a model, and the proper fee, and, in thé petition, appointed Munn & Co. “ to act as his attorneys in presenting the application and' making all such alterations and • ■ amendments as may be required, and to sign his name to the drawings.” The affidavit, that Eagleton verily believed him- • self to be “the original and first inventor of the within described improvement in furniture springs,” was sworn to by him June 26th, 1868. The specification then filed was as follows : “ Be it known that I, J. Joseph Eagleton, of New York, in the county of New York, and State of New York, have invented a new and useful improvement in furniture springs, and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in 'the art to make and use the same, reference being had to the accompanying dra hgs forming part of this specification, in which the drawing- represents a furniture spring provided, according to my improvement, with a japan covering. : [The nature of this invention relates to improvements in helical furniture springs, such as are used for mattresses, sofas, &c., the object of which is to provide steel springs which will not he so liable to injury from corrosion as those now in use. It consists in providing steel springs, such as are commonly used, with a japan outer covering. Steel springs, as is well known, possess in a much higher degree the requisite qualities of strength, flexibility, and elasticity than iron, copper, or brass, and, by reason of the susceptibility of steel to be tempered,- and thereby regulated to any degree of elasticity, it is much more preferable to use; but, owing to its great liability tó de
The application was rejected on the 10th of July, 1868, the following reasons being assigned by the examiner: “ The application above referred to has been examined, and is rejected for want of patentable invention. The japanning of metal is an old process, and no invention is shown in applying it to a spring for a bed bottom. It is a common right, possessed by .every one, to galvanize, paint or japan any metal that he may use.” The specification was returned to the applicant. Eagle-ton died in February, 1870. On December 29th, 1870, the application for the patent was renewed on the same specification, it being returned to the Patent Office, and received there January 4th, 1871, and a reconsideration requested, the letter being signed “J. J. Eagleton, per Munn & Co., attorneys.” Nothing further appears to have been done until, on October 19th, 1871, the specification filed was amended by erasing the part above put in brackets, and substituting what is in brackets in the specification of the patent as issued, and by substituting the following as the claim: “ Having thus described my invention, I claim as new, and desire to secure by letters patent, ns
The bill avers that Eagleton, having invented the improvement, died intestate, and Sarah N. Eagleton was appointed his administratrix, and the invention was assigned to the plaintiff, and afterwards the administratrix applied for a patent, and
The Circuit Court dismissed the bill, assigning its reasons in an opinion which is found in 18 Blatchford, 218. The court decided the following points : (1.) The patent is for steel furniture springs protected by japan, and tempered by the heat used in baking on the japan. (2.) Such springs, so protected and tempered, were known and used by various persons named in the answer, before the date of the patent. (3.) The specification which accompanied the original application did not set forth the discovery that moderate heat, such as may be applied in japanning, will impart .temper to the springs, but set forth merely the protection of the springs by japan. (4;) Not only does the evidence fail to show that Eagleton in fact made and
We are satisfied with the conclusions arrived at by the Circuit Court, and with the reasons assigned by it therefor. The' copy of the file wrapper and its contents in the matter of the patent, from the Patent Office, giving the history of the application, was put in evidence by the plaintiff. It shows beyond doubt, that there was w suggestion, in the specification signed and sworn to by-Eagleton, of the invention described in the amendment filed.October 19th, 1871. Prior to that-time the process practised by the defendants, which is the process described in letters patent No. 116,266, granted to Alanson Cary, June 27th, 1871, for an “ improvement in modes of tempering springs,” was invented and put in use; and there is no sufficient evidence that Eagleton had any knowledge, prior to the invention by Cary of the Cary process, of either that process or of the process described in the patent 'in suit. The plaintiff’s patent shows, on its face, that it was granted on the petition of Eagleton, and the allegation of the bill that the patent was granted on the application of his administratrix is not established. In view of the entire change in the specification, as to
The decree of the Circuit Cov/rt is affirmed.
