This ease comes before the court upon a motion for a preliminary injunction to restrain the defendant from making a certain form of pocket-book clasp, which, as the plaintiffs contend, infringes upon certain patents owned by them.
The bill sets forth three patents,—
One, No. 47,135, issued to Charles Seaver, April 4,1865, and assigned to the plaintiffs Zinn and Messer, October 18, 1879 ; another, re-issue No; 8,106, dated February 26, 1878, issued to Zinn and Messer, assignees of Louis Messer; and another, re-issue No. 8,123, dated March 12, 1878, issued to the same parties.
The invention described in the Seaver patent is therein stated to consist in—
A metallic plate, to be applied to the under lap or portion of the article of wearing apparel, and provided with a projecting pin or stud and a hinged cover or button, as it may be termed; the whole being so made and applied that the cover shall shut down upon the top of the stud, and enclosed under it the upper lap or portion of the coat or garment, which is to be provided with a hole or recess to put down over the stud.”
The claim is for an—
“Improved clolhes-fastening attachment, the same consisting of the plates a and d, and the stud /, they being constructed and to operate in connection with an eyelet or hole in the outer flap of the garment, substantially in manner as hereinbefore explained.”
In respect to this patent the defendants say—
First. That it is limited by the terms of the specification to a mode of fastening for garments, and inasmuch as the defendants make a clasp intended to be used on pocket-books, and nothing else, they do not infringe.
The answer to this position is that the Seaver patent secures the combination or machine therein described, with[916]*916out regard to the purposes for which the fastening is intended; and if the defendant’s clasp is in substance the same as that described in the Seaver'patent, it constitutes an infringement of that patent, notwithstanding it is intended to be employed for a purpose not mentioned in the patent. The next position taken by the defendant Is—
That if the Seaver patent is held to cover the device therein described, without regard to the purposes for which it may be applicable, then the invention is anticipated by the ordinary corset fastening and the ordinary hand-bag fastening, of which specimens are put in evidence.
But the corset fastening and the hand-bag fastening differ from the Seaver clasp in this; that in the Seaver clasp the button or cap is connected with, and hinged upon, the base, and the clasp operates by retaining between the cap and the base the article intended to be clasped; while in the corset fastening and the hand-bag fastening the two plates are not connected together, or hinged one upon the other, and the fastening is accomplished by attaching one plate to one side of the corset, or bag-opening, and the other to the other side, and then slipping an eyelet placed in one plate over a stud placed on the other plate. The difference between the two devices is plain and substantial.
The last position taken in respect to this patent is—
That au essential feature of the device is that the cap and base plate are connected by a jackknife hinge, and the defendant’s clasp is no infringement, because it contains no jackknife hinge.
As I understand it, there must be a spring and also á pintle to constitute a jackknife hinge. The description of the drawings given in the Seaver patent states that the cap and base are connected by a jackknife hinge, but further on it is expressly stated that the spring may be dispensed with. I am unable, therefore, to say that a jackknife hinge is an essential feature of the device described in the Seaver patent. I have no difficulty, however, in holding that an essential feature of the Seaver invention, as described in the patent, is a cap and base plate connected together by means of a hinge, of which a pintle forms a part.
But assuming that the Seaver patent is for a combination wherein a spring-is not, and a pintle is, an essential element, [917]*917the ease of the defendants is not helped because of the Messer patents owned by the plaintiffs and set forth in the bill, namely: re-issue No. 8,106, and re-issue 8,123. The patent re-issue No. 8,123 is for a clasp consisting of three pieces—a base plate, a cap with a tail-piece, and a spring.
These parts are constructed so that the cap shall hinge upon and engage with the base plate without the use of a pintle or its equivalent, and so that that part of the cap called the tail-piece, by pressing upon the free end of a spring attached at the other end upon the bottom of the base, holds the cap and base in connection, while, at the same time, the cap is permitted to swing in and out, and so to clasp between it and the base any article desired to be held thereby.
The invention described in re-issue No. 8,106 is the same as that described in re-issue No. 8,123, with this single exception : that it has a stud attached to the base plate upon which the cap shuts, and the article intended to be clasped is held by means of an eyelet that slips over the stud, instead of by an abutment upon the article clasped, as in re-issue No. 8,123. The defendant’s clasp is intended to produce precisely the same result as that accomplished by the Messer clasp. It consists of three pieces—a base, a cap having a tail-piece, and a spring. These parts operate together in the same manner as do the same parts in the Messer clasp, the only difference being that in the defendant’s clasp the whole of the rear end of the cap is bent down to form the tail-piece, instead of only a part of the cap, as in the Messer clasp. This distinction does not, in my opinion, constitute a difference. The functions of the tail-piece are the same in both clasps. Such a form of tail-piece as that employed in the defendant’s clasp would be suggested almost as a matter of course by the tailpiece of the Messer clasp.
The defendant states in his affidavit that advantage is gained by his form of construction, but what that advantage is does not appear, nor is there any evidence except the bare statement of the defendant that the cost of the clasp is reducod by making it in his form. So far as I have been able to discover, the two clasps accomplish precisely the same result by [918]*918means substantially the same. There is no difference in prin. ciple between them. The form of hinge employed in the defendant’s clasp can be no more than the mechanical equivalent for the hinge employed in the Messer clasp; but I incline to the opinion that all that has been effected by the defendant is a colorable change in form
But it is said the defenda: it has been awarded a patent, No. 221,377, by virtue of which he makes the clasps complained of, and therefore has the determination of the patent-office that the change he has introduced is substantial, and he is therefore entitled to go to final hearing before being subjected to an injunction. But no such patent is set up in the answer, and therefore no question as to the effect of the patent referred to can arise upon this motion.

But no such patent is set up in the answer, and therefore no question as to the effect of the patent referred to can arise upon this motion.
Upon the papers as they stand, showing, as they do, among other things, a general acquiescence in the plaintiff’s claim under these patents, I see no reason for doubt upon the question of infringement of the Messer patents, and must grant an injunction, provided the Messer patents are valid. But the validity of the Messor patents is denied for want of novelty. The only evidence in support of this charge relates to clasps made and sold by one Kohlman more than two years prior to the Louis Messer application. The Kohlman clasp consists of—
A base plate, a box extending over a considerable part of the base plate and fastened thereto, a cap extending over the rest of the base plate and hinged to the front edge of the bo : by means of two ears formed on the cap, on which the cap swings. Ti e inner end of the cap has a tail-piece bent down under the box, so as to rest upon the free end of a spring, which is secured at the other end u ton the bottom of the base plate. The base plate has a stud whereon tlio cap rests when shut, over which an eyelet in the article intended to be clasped slips, and so is held.
The differences between tho Kohlman clasp and the Messer clasp are these: The Messor clasp dispenses with the box fastened upon and covering half of the base, to which the cap is attached by means of the ears, dispenses with the ears upon which the cap turns, and makes the tail-piece of the cap to engage directly with the base'plate, without the employment of either pintle or oars, and to rest upon the spring [919]*919on the under side of the base in such a manner that the base and cap are held in connection with each other without any other fastening, while the cap is permitted to hinge directly upon the base, and so to close upon a stud or abutment, as the case may be. Evidently the Messer clasp accomplishes the same result as the Kohlman clasp, but it accomplishes this result by different means. The base and cap in the Messer clasp are not equivalent to the base, cap, and box in the Kohlman clasp. In the Kohlman clasp the cap does not engage with the base, as in the Messer clasp. In the Kohlman clasp the cap and box are connected together by means of ears, and the box secured to the base. In the Messer clasp no ears are employed, and the cap is held in immediate (jonnection with the base by the operation of the spring upon the tail-piece of the cap. These differences are substantial. By means of these a clasp is produced costing less to manufacture, while at the same time it is more durable, for all danger of the box working loose from the base is avoided,—a result fatal to the efficiency of the Kohlman clasp. The importance of these differences is proved by the fact that the plaintiff does not seek to restrain the manufacture or sale of the Kohlman clasps, and the further fact that the Kohl-man clasps are no longer in the market, while there is a demand for the plaintiffs’ clasp.
I am of the opinion, therefore, that the plaintiffs’ clasp is not anticipated by the Kohlman clasp, and that the Kohl-man clasp affords no ground upon which to hold the Messer patents void for want of novelty. My conclusion, therefore, is that the plaintiffs are entitled to a preliminary injunction.
