The result is that no infringement was made out. Therefore, no injunction should have been issued. The court below reached the saIne result on another ground, which we do not find it necessary to consider. The decree of the court below is affirmed.
OFFICE SPECIALTY MANUF'G CO. v. WINTERNIGHT &: CORNYN MANUF'G . CO.
(Oircuit Court, E. D.· Pennsylvania. May 14, 1895.) No.30.
Conclusive effect is accorded by each of the federal circuit courts to prior judgments of any of the others in patent cases, where the patent, the question, and the evidence are the same in both. suits, not on the ground of comity alone, but with the practical and salutary purpose ot avoiding repeated litigation and conflicting decrees upon matters which, having been passed upon by one court of first instance, ought to be referred to a court of appeal for authoritative determination.
The Smith and Shannon patent, No. 217,909, for an improvement in paper holdel1l, held not anticipated by the English patent to Stephen Dixon. of November 9, 1864; and also held infringed as to claims 1. 2, 3, and 5.
This was a bill by the Office Specialty Manufacturing Company against the Winternight & Cornyn Manufacturing Company for in· fringement of a patent relating to paper holders. Church & Church, for complainant. Hector T. Fenton, for defendant. DALLAS, Circuit Judge. This suit is for an injunction against and an accounting by the defendants, who, it is alleged, infringe elaims 1, 2,3, and 5 of letters patent No. 217,909, granted to Freder"io W. Smith and James S. Shannon upon July 29, 1879, for "improvement in paper holders." This patent has been twice before the circuit court for the Northern district Of Illinois. Upon the first occasion, claims 1, 2, and 3 were considered, and upon the second occasion all the claims now in question were involved. In both cases the validity of the patent was upheld. Shannon v. Printing Co., 9 Fed. 205; Schlicht & Field Co. v. Chicago Sewing-Mach. Co., 36 Fed. 585. This court will not examine anew the question which has thus been adjudicated, but will accept the decisions referred to as determinate of the effect of the evidence upon which they were based. Wanamaker v. Manufacturing Co., 3 C. C. A. 672, 53 Fed. 791. If the rule here adverted to were one of "comity" merely, it would, I think, be impossible to justify its derogation from the right of suitors to the veritable judgment of the tribunal to which any particular case is confided for decision. Upon general qUe'stions of law, the vi.ews

ot courts of co-ordinate jurisdiction are always regarded with respectful consideration, but never as controlling. In patent causes, however, conclusive effect is accorded by each of the circuit courts of the United States to a prior judgment of any other of them, wherever the patent, the question, and the evidence are the same in both suits, not on the ground of comity alone, but with the practical and salutary object of avoiding repeated litigation and conflicting decrees in the courts of the several districts upon matters which, having been once passed upon by a court of first instance, ought to be referred to a court of appeal for authoritative determination. National Cash-Register Co. v. American Cash-Register Co., 3 C. C. A. 559,53 Fed. 370. Defendant's counsel has directed attention to two decisions, both of later date than either of those made by the circuit court in Illinois, which, he contends, should prevent the latter from having conclusive effect; but it is only necessary to read the opinions in the two cases referred to, in order to perceive the futility of this contention.' In Office Specialty Manuf'g Co. v. Globe Co., 65 Fed. 599, the patent was not the same as in this case; and in Office Specialty Manuf'g Co. v. Cooke & Cobb Co., 64 Fed. 133, the application was for a preliminary injunction, and upon the ground that the question of patentable invention was, "to say the least, a doubtful one," an injunction was denied; but the court did not regard the question as open even to the admission of a doubt, except as it was affected by evidence which had not been adduced in the Illinois cases. This new evidence consisted of a certain "English file," which has not been introduced here, and of the "Dixon patent," which, as it also constitutes the only substantial additional evidence will now be considered. That patent is an in the present English one to Stephen Dixon (No. 2,780), dated November 9, 1864. In the absence of any expert testimony to explain it, I might, perhaps, properly decline to pass upon this patent. Waterman v. Shipman, 5 C. C. A. 371, 55 Fed. 987. I have, however, examined it, with the aid of the ingenious suggestions of counsel, and believe that, if it had been before Judge Blodgett in the cases in the Illinois district, it would not have affected his conclusion. It clearly appears that he was of opinion that the patent then and now in suit covered several material features which are not shown by the Dixon patent; and my own investigation of that patent satisfies me that, in several other essential particulars as well, it falls very short of being 'an anticipation. But I content myself with applying to it some of the remarks made by Judge Blodgett with relation to certain other earlier patents, viz.: "It also lacks the feature of ready removability of parts roo as to admit of close packing for transportation"; and it does not "show a practical duplex paper holder, with a tablet, and arranged with more than one parallel ring, composed ot puncturing and transfer wires operating together, as shown by com· plainant's device." Upon the question of infringement, I do not deem it necessary to enter upon a comparison of the two devices. When examined side by side, and in the light of the construction given to the claims in v.67F.no.7-59
suit by the court in Illinois, and of all the expert testimony in this case, it appears to me to be plain that the defendant's file embodies all the elements of the plaintiff's contrivance, and that the former accomplishes precisely the same objects as the latter, and in sub. stantially the same manner. A decree for the plaintiff upon all thb claims involved will be .entered.

PROCESS PATENTS-WHAT IS PATENTABLE.
A purely mechanical process, involVing no cbemical or otber elemental action wbich is separable or distinguishable from the function of the mechanical devices used to produce tbe result, is not patentable. Locomotive Works v. Medart, 15 Sup. Ct. 745, followed. Tbe Henderson patent, No. 412,751, tor a process of manUfacturing metaillc crossbars and rails for window sashes and analogous structures, held invalid, as covering a purely mechanical process.
8. PRODUCT PATENT-WINDOW SASH. The Henderson patent, No. 420,510, for improvement in window-sash bars, designed to be made by the process described In patent No. 412,751,
must be restricted, In view of the prior state of the art and of the amendments made in the patent office, to the particular forms of construction described, and is not infringed by wlndow-sasb bars made in accordance with the Schuhmann patent, No. 415,068.
Appeal from the Circuit Court of the United States for the Northern District of Illinois. This was a bill by William Henderson against the Wells Glass Company and Herman Schuhmann for alleged infringement of certain patents relating to window sashes and analogous structures. The circuit court sustained the patents, found that they were infringed, and entered a decree for an injunction and an accounting. Defendants appealed.
The appellee, William Henderson, is the grantee of letters patent No. 412,751 and No. 420,510, Issued October 15, 1889, and February 4, 1890, respectively,the first for a "process of manufacturing metallic crossbars and ralls for window sashes and analogous structures," and the second for "Improvements in wlndow-sash bars," designed to be made by the process descrtbed in the first patent. The bill charged the appellants, the Wells Glass Company and Herman SchUhmann, with Infringement of both patents, and prayed an injunction and an accounting. 'l'be defendants answered, setting up a license, and denying both invention and infringement. General replication. The court below considered that both patents were valid and had been infringed, and decreed an injunction and accounting as prayed. The specification, drawings and claims of tbe second patent, wblcb, it may be noted, was first applied for, are as follows: "Belt known that I, William Henderson, a subject of the queen of Great Britain, residing at Chicago, in the county of Cook and state of Illinois, have Invented certain new and useful Improvements In window-sash bars, of whicb the following Is a specification.
