by which this operation or process may be performed; and each may be entitled to his patent. Corning v. Burden, 56 U. S. 252, 14 L. Ed. 683. There is no claim in the plaintiffs' patent for any particular machine by which this process of expanding metal is accomplished, and we see no reason why the means of performing the process patented by the plaintiffs cannot be embodied in at machine and patented by the defendants. Cochrane v. Deener, supra. So that, in so far as the plaintiff's bill relies upon the mere creation of the machine by the defendants to perform the process which he has patented, as an infringement, it must fail, as the defendants would have a right to construct and patent such a machine. It is entirely separate and apart from the process which the machine is intended to accomplish. Robinson on Patents, §§ 904, 925. The evidence, however, is that the defendants infringed the plaintiff's patent in using its process, and expanded metal, to some extent, was produced by their machine by the same process covered by the plaintiff's patent, and without its permission. To that extent the rights of the plaintiffs in the patent in suit were infringed. The metal manufactured under the process of the plaintiffs' patent was produced here in Philadelphia prior to the bringing of this suit, and whether it was produced by a perfect machine, or not, can make no difference. The patented process was used, and the infringement complete.

The plaintiffs' bill is therefore sustained, and a perpetual injunction awarded.

RUMFORD CHEMICAL WORKS v. NEW YORK BAKING POWDER CO. et al.

(Circuit Court, S. D. New York. January 3, 1905.)

PATENTS-CONTRIBUTORY INFRINGEMENT.

One who manufactures and sells an element in an infringing baking powder to be used by the purchaser in making such baking powder is a contributory infringer, and liable equally with the purchaser for the profits or damages resulting from the sale of the infringing article.

[Ed. Note. For cases in point, see vol. 38, Cent. Dig. Patents, § 402. Contributory infringement of patent, see note to Edison Electric Light Co. v. Peninsular Light, Power & Heat Co., 43 C. C. A. 485.] In Equity. On motion for modification of decree. Antonio Knauth, for the motion.

C. A. L. Massie, opposed.

LACOMBE, Circuit Judge. It seems unnecessary to alter the phraseology of the decree, which does not now require an ascertainment of the profits made by the Provident Chemical Works in manufacturing the phosphatic-acid element. As to acid made by it and sold to the New York Baking Powder Company it is a contributory infringer, and is liable equally with the baking powder company for profits or damages resulting from the sale of baking powder in which the acid contributed by it has entered as an ele

ment.

MILLS v. RUSSELL MFG. CO.

(Circuit Court, D. Connecticut. April 4, 1905.)

No. 1,157.

PATENTS-INFRINGEMENT-CARTRIDGE BELTS.

The Mills patents, Nos. 756,177 and 756,178, for cartridge belts, construed, and held not infringed.

In Equity. Suit for infringement of letters patent Nos. 756,177 and 756,178 for cartridge belts, granted to Anson Mills March 29, 1904. On final hearing.

Marcellus Bailey, for complainant.

H. A. Seymour, for defendant.

PLATT, District Judge. This is a suit charging infringement of two letters patent granted to complainant for improvements in cartridge belts-Nos. 756,177 and 756,178-both dated March 29, 1904, and capable of conjoint use in the one belt. The infringement complained of is based upon a contract with the government dated May 2, 1904, entered into by the defendant, to manufacture and sell certain belts, similar to a sample belt marked "B," which was submitted with the bid and made a part of the contract, which plaintiff claims contains the invention of the patents in suit. This is substantially the same as the belt which on October 24, 1904, was pronounced satisfactory, and which will be made and delivered under the contract; the only difference being that Sample B is handmade, and not quite as neat and uniform as the latter. On all the issues, it would seem immaterial which belt shall be made the basis of discussion. The latter is Exhibit Russell Manufacturing Company's 1904 Cartridge Belt. When preparing to bid, defendant found at the War Department a sample belt like complainant's Exhibit Sample Belt. It refused to follow the sample, giving as the reason that the construction of the pocket on that belt was patented, but guarantying one equal, if not superior, to the sample, and one more presentable and useful; but nothing was said about the narrow end which forms the subject of the other patent.

The defenses are: (1) noninfringement; (2) lack of patentable invention; (3) lack of novelty.

It is imperative to set forth the somewhat peculiar history connected with the belt of patent 756,177, before it is possible to construe the claim with any accuracy. The outlines alone will be sketched in. Prior to 1902 complainant had enjoyed the privilege for many years of furnishing the government with service belts for carrying individual cartridge's, which were known as single or double loop belts. In 1902 a new rifle was adopted, which required cartridges in clips; five cartridges being held together by each clip. Since this model could not at once displace all the service rifles, it followed naturally that a belt was required which should not only retain the clips when the belt was carelessly handled, but should be so constructed as to prevent single cartridges

from slipping out in like circumstances. In February, 1903, Gen. Mills, the complainant, was asked to submit a suitable belt to meet the emergency. He complied, but on March 28, 1903, the board of ordnance condemned all the samples which had been submitted, giving divers reasons for such action, and offered suggestions as to what was needed. From these we find that the board suggested that the belt to be satisfactory must have (1) ten pockets instead of eight; (2) pockets must be without thimbles, aprons, or partitions; (3) the flaps must be of single thickness and as short as possible; (4) that part of the body of the belt having no pockets should be reduced in width to 134 inches immediately after the end pockets; (5) the two ends of the belt must be secured by a bronze buckle, which should always remain equally distant from the end pockets, and the belt should be capable of easy and quick fastening. Both complainant and defendant submitted samples and bids in accordance with the suggestions contained in the board's report. The defendant's bid was far below that of complainant, but was rejected, without giving any reason, so far as appears. Complainant's bid was rejected because it was excessive, although the department had known in advance what the bid was to be, and had suggested no reduction. When the unfavorable report of March 28, 1903, was handed to complainant by Capt. Gibson, it appears by Gen. Mills' testimony that Capt. Gibson told him a narrower buckle was advisable, and asked him if he could not prolong the belt from the last pocket on either side 13 inches, so as to have two narrower webs or billets at each end, to which the narrower buckle could be adjusted. After the June bids were rejected, proposals were again issued on July 25, and the bids were opened on August 25, 1903. Complainant submitted again the samples offered at the June bids, materially reducing its price on belts and suspenders; the defendant offering no belt, but submitting suspenders with prices. Complainant's bid was accepted, and the sample with equal width until the very end is reached was adopted, and the contract with the government signed, October 19, 1903.

The original application for patent 756,177 was filed August 12, 1903, which was, as will be seen, during the suspense between the proposal for bids of July 25 and their opening on August 25, 1903. As filed, it covered both narrowed ends and pockets. It was divided, and the divisional application was filed October 14, 1903, five days. prior to signing the contract under which the long billet ends were not accepted. This application, viewed from any angle which the observer may desire, is an exceedingly interesting production, and deserves careful examination. Time is too precious to permit me to dissect and analyze the proceeding as minutely as it warrants. The drawings of the original application present the precise construction suggested by the March 28, 1903, report. One element of the combination in the claims is the "narrow end portions, A'." The specification states that "the pockets stop short of the ends of the belt, and these ends are reduced in width as shown; this being for the comfort and convenience of the wearer, and to permit of the use of fastening devices of small dimensions." It will be remembered

876

that Capt. Gibson, from the board, had told Gen. Mills soon after the March 28th report that a narrower buckle was advisable, and asked him if he could not prolong the ends, with that idea in view. The specification then proceeds to explain how to form the narrow ends with selvage edges, and protect the place where the reduction in width occurs at the shoulders, c, by metallic binders, d. In all this the thought clearly is to get long, narrow ends, so that the fastening buckle can be narrow, and to prevent raveling where those ends begin to be narrow, by housing with metal the threads which were cut off in the loom where the width of the selvaged webbing was suddenly reduced. The purpose of the shoulder, c, is obvious. It is further explained in the specifications how the narrow ends can be "bent back on themselves" to hold "buckles, clasps, or other fastening devices." The inference is irresistible that on October 14, 1903, when the divisional application was filed, the long, narrow end was a feature of the belt which was believed to have found favor in the eyes of the authorities, and was worth nurturing and protecting.

The application of October 14, 1903, which has just been partially explained, was allowed November 9, 1903. In the meantime the government had entered into the contract with complainant. for belts like the other sample, on which no long, narrow end appeared. It would seem to have taken a few days for the patentee to recover from the shock which the changed condition of things produced. At any rate, he invested no additional funds when notified of the allowance. On the contrary, a request to amend the application, under rule 78, without withdrawing the case from issue, was recommended by the examiner, and approved by the acting commissioner. In accomplishing this extraordinary feat, the patentee not only took out the old specifications and claims, and inserted new ones, reducing the claims to one, on account of surplusage, but canceled the old drawing and substituted a new one; saying as he did so:

"This new drawing is furnished because of the oral suggestion of the examiner that the construction which is the subject of the application, although clearly set forth in the specifications, is somewhat obscure in the original drawing."

I am constrained to applaud the acumen of the examiner. The original drawing shows ten pockets. The unpocketed portion is materially reduced in width immediately after the end pockets. The long, narrow ends are shown as bent back upon themselves. The amended drawing shows nine pockets. Vide contract of October 19, 1903. The unpocketed part is only slightly reduced in width, and that reduction does not take place immediately after the end pockets, but considerably beyond that place. The attempt to show the ends bent back upon themselves is weak, and in Fig. 2 what little, narrow end does exist is pretty much all cut away. The specification undertakes to convey the idea that the narrowed ends are devised to permit the use of narrow fasteners, which, by bending back, may be engaged with eyelets between the pockets

on the under portion of the belt. The narrow center buckle idea of the original application has vanished into thin air.

With this monstrosity allowed in December, the final cash investment was deferred until March 7, 1904, and on March 10, 1904, the department sent out proposals for the bids of April 9, 1904. The patent was issued March 29, 1904, and 11 days later the bids were opened. The proposals of March 10th called for a belt of uniform. width throughout its length, and provided with nine pockets. The defendant's bid was accepted, and we now come back to the question of whether the belt which it proposes to furnish is an infringement of the patent in suit No. 756,177.

In connection with my story of the divisional application, I have, I think, commented sufficiently to show that my conclusion obviously must be that the "narrowed ends" of the patent in suit must be the "narrow end portions, A'," of the original application, shown. in both specification and drawing, and appearing again in the drawing of the patent, and that, since no such narrowed end can be found in defendant's proposed belt, there can be no infringement found in this respect. In the patent in suit another limiting feature shown, is that the cartridge pockets on the belt are "formed integral therewith." Patents 399,924 and 666,687 are referred to in the specifications, and from them we can obtain light on the meaning of those words. Both of the patents referred to show a belt in which the two sides and bottom of the pockets are woven integral with the body of the belt, and compel us to so construe them now. The defendant's pockets are not woven integral with the body of the belt in the three necessary directions. They are formed by weaving long loops, integral with the belt so far as the sides go, but open at both ends. The lower end is then firmly stitched into the belt, and in this way a pocket is made. This is a small matter, but is worth noticing. There is a determined effort made by complainant to sustain his theory of the narrow end fastening invention, by claiming that the wide end fastenings, which hooked over the two sides of the belt, and which have been used since 1889 in the army, under complainant's patent of March 4th of that year, and are still in large use, mutilated, chafed, abrased, and horribly tortured the soldiers. Complainant's wide army experience, and that of his expert, are placed in high light for the purpose of bringing out the most effective contrast. If one could believe that a kindly government had permitted such horrors to continue for such an unreasonably long time, with wider, tighter, and unsuspended belts, it is impossible to be satisfied that the suffering must continue as long as the hookover fastenings are used, now that the belts are narrower and looser, and are largely sustained by the shoulders, from which they practically hang by the suspender. The picture of the tortured soldier is, in my opinion, an elusive fantasy. The board of ordnance complained about the hook fastenings because they wore out the edges. of the webbing, and said no more. The original specifications failed to invoke this "field service" argument. I cast it aside.

Having reached the conclusion indicated, it would be wasteful to follow the various elements of the claim to the last analysis, as sur
