67 F. 790 | 1st Cir. | 1895
This is a suit in equity in behalf of the Clinton Wire-Oloth Company, wherein it is alleged that the defendant has infringed two letters patent,—one for an improvement in the art of weaving wire cloth, and the other for an improved shuttle whereby the improvement in such art may be practiced. The complainant contends that prior to its inventions there was a practical difficulty in weaving wire cloth by means of a shuttle carrying a cop of wire; and that the difficulty resulted from the fact that the wire, as it lay on the cop, in coils substantially at right angles to the axial line of the shuttle, necessarily at each turn, as the coil was paid out longitudinally from the cop, took into itself turns of twist, by reason of which the wire constantly tended to resume the spiral form in which it was while w'ound on the cop, instead of remaining in a straight line in the web, as was necessary in order to accomplish satisfactory work.
The complainant claims, under patent No. 239,012, dated March 15, 1881, known as the “Art Patent,” an invention which effectually removes this difficulty,by swaging the twist into the body of the wire, which result, it is claimed, is accomplished by straining the wire around rollers as it passes from the cop to the loom and its place in the web. Under its other patent, No. 239,011, dated March 15, 1881, the complainant presents a combination shuttle consisting of a shuttle body for weaving wire, with a cop case or chamber, to contain the wire and swaging rolls, around which the wire passes after leaving the cop, and before leaving the shuttle, whereby the twists of the wire are swaged into its body, and smooth weaving insured. So it will be seen, that under the Art patent; which is. the first patent mentioned here, the complainant seeks to monopolize or control the means of swaging or straightening wire as it passes from the cop to the web; and that, under the second patent named, he seeks to control or monopolize the use of a combination shuttle, which it is said effectually performs the work.
We are of opinion that the means of straightening or swaging wire, as a general proposition, are old and well known, and that it has been understood for a long time that wire having crooks or twists could be straightened either by a hammering process, or by drawing the wire under tension around a rigid body or hard substance, like the horn of an anvil, for instance. It is probable that the boy is rare who has not in his playdays been confronted with the problem of straightening crooked or twisted wire, and it may be safely said that the problem was readily solved by holding one end of the wire in each hand, and drawing it firmly around some hard substance; and it mattered not, except in degree, whether the substance was a fixed rounded, or circulating, surface. It is probably true that the molecular condition of crooked or twisted wire is in a measure changed when subjected under tension to any of the old and well-known processes of straightening; and it therefore follows that the complainant’s first or “Art Patent,” so-called, should not, if sustained, be construed so broadly as to give a monopoly of all the means of straightening or swaging wire in the wire-weaving industry; and as we dispose of this case without passing upon the validity of the
As has been said, the complainant’s device covered by his shuttle patent is the combination of a shuttle body for weaving wire wilh a cop case or chamber to contain the wire and with swaging rolls, around which the wire passes after leaving the cop, and before leaving the shuttle. In this machine or combination shuttle there are three rolls, which are designated as “swaging rolls,” and two other rolls, which are denominated as the usual “delivery rolls.” The wire, under the strain of weaving, passes around the three first named, and then around one or the other of the delivery rolls, to its place in the web. As the shuttle is passed from one side of the loom to the other, the wire is drawn around the delivery roll nearest to the point to which the shuttle is directed. The complainant does not claim that the two rolls called “delivery rolls” are new, or that they perform in this device any necessary swaging function; and in fact it is conceded that they were in use and known to the public as delivery rolls, both in wire and textile fabric weaving, long before the complainant’s alleged invention. The device known as the “Combe Patent” was an English device invented in 1857, and was designed to be used in the textile fabric industry. It possessed a semicircular friction block or post, which performed the double function of putting friction upon the weft thread, and of guiding the thread on its course to the'loom. It also possessed a steel channel or groove on the side of the shuttle, through which the thread was drawn as it was delivered to its place in the web. While this device was limited in design and in use to weaving textile fabrics, and had no reference whatever to the idea of swaging turns of twists from weft-wire threads in the wire-weaving industry, it unquestionably embodied the means of performing that function. Perhaps not satisfactorily, but it possesses the means and will accomplish the work in a degree. It is urged by the learned counsel for the- complainant that the problem of swaging turns of twists into wire thread was never presented in the textile-fabric industry during the life of the Combe patent. If this be so, “doubtless a patentee is entitled to every use of which his invention is susceptible, whether such use be known or unknown to him” (Potts v. Creager, 155 U. S. 597, 606, 15 Sup. Ct. 194); and, if the Combe patent were in force, the patentee would doubtless be entitled to control the use of his device in the wire weaving as well as in the textile fabric weaving industry. Under the doctrine which gives to the patentee all the uses to which his invention is susceptible, whether known or unknown, it is difficult to see why the public should not be entitled to all the uses to which the means involved in devices covered by lapsed patents are susceptible, or why a patentee who employs the old means with improvements adapting the use to a new or nonanalogous industry should not be limited to a monopoly of the combination or improved machine. To say that one who discovers that old means will do
On the view most favorable to the complainant, all its alleged invention does is to adapt or apply old and well-known means to a, new use and new material; and if the question as to the validity of the patent were a question necessary to a decision of this case, and if “the patent could be sustained at all” (Brook v. Aston, 27 Law J. Q. B. 145, 28 Law J. Q. B. 175, 176; Potts v. Creager, 155 U. S. 597, 606, 607, 15 Sup. Ct. 194; Watson v. Stevens, 5 U. S. App. 101, 107, 2 C. C. A. 500, and 51 Fed. 757; Pennsylvania R. Co. v. Locomotive Engine & Safety Truck Co., 110 U. S. 490, 494, 4 Sup. Ct. 220; Brown v. Piper, 91 U. S. 37; Roberts v. Ryer, Id. 150; Atlantic Works v. Brady, 107 U. S. 192, 2 Sup. Ct. 225; Tucker v. Spalding, 13 Wall 453; Rob. Pat. § 259, and note 1), “it would have to be restricted and confined to the specific combination described” in the specification and claims (Knapp v. Morss, 150 U. S. 221, 228, 14 Sup. Ct. 81; Duff v. Pump Co., 107 U. S. 636, 639, 2 Sup. Ct. 487; Newton v. Furst & Bradley Co., 119 U. S. 373, 7 Sup. Ct. 369; Bragg v. Fitch, 121 U. S. 478, 484, 7 Sup. Ct. 978; Dryfoos v. Wiese, 124 U. S. 32, 37, 8 Sup. Ct. 354). If, therefore, we were to anfreune in this case that the wire-weaving industry is nonanalogous to the textile-fabric industry, and that the complainants. combination was patentable as a combination of old means with improvements adapting it to a new and nonanalogous matada! and use, still the monopoly would be limited to the continuation, and would not extend to the old means employed in the new industry without invoking the aid of the Improvements involved in. the new combination or device, for which the complainant seeks protection.
The Tunstill patent óf 1864 was a device for textile weaving, and employed a tubular gudgeon and a round roller as means for protecting weft thread from becoming entangled as it passed from the cop; and. the Bigelow 'patent of 1857 was designed as an improved device for use in weaving wire cloth, and employed a series of pins, which were designated as a “wire straigh tener,” through which the wire was drawn out from the bobbin between guide rollers to the loom, and to the pins there was applied a spring to hold the pins “in greater or less proximity, according as more or less pull is required to straighten the wire.” It is also claimed for the last-named device that “two conforming friction surfaces may be employed to straighten the wire, said surfaces being pressed together by a spring, and the wire drawn between them.” The Washburn patent of 1863 covers a wire-straightening machine with fixed points or rollers, whereby it is claimed that “wire may be more readily and effectually straightened than by machines hitherto employed for tills purpose,” and it sets forth that the wire is to be drawn between fixed points or rollers. Without pursuing the state of the art or older devices farther, it may be observed that weavers of wire and textile cloths
The decree of the circuit court is reversed, and the case remanded to that court, with directions to dismiss the bill, with costs.
