Opinion

NIXON, District Judge.

This bill is filed against the corporation defendant, for infringing certain letters patent, No. 130.961, issued to William Webster, August 27, 1872. for “a new and useful improvement in looms for weaving pile fabrics.”

The answer denies the infringement, and sets up, as a defence, a prior invention by one Ezekiel K. Davis; and that letters patent were granted to him, for inventions in looms for weaving pile fabrics, dated February 9, 1869, and numbered 86,651; that the looms which the defendants had in use, and which were alleged in the bill of complaint to infringe the Webster patent, were constructed and operated in conformity to the description contained in the said patent to Davis; that defendants had a license under said patent to use said looms; and that they rightfully and lawfully used under said license.

I. The complainants’ patent refers to the wire motions of a loom in the manufacture of pile fabrics. It is a patent for a combination; and the question of infringement is determined by the construction of the fifth claim, which, in the specifications is stated as follows:

“In combination, the lay and its rigid shuttle-box, the pivoted vibrating wire trough, the reciprocating driving slide, and the latch moving thereon, the latter being operated by the wire box, the combination being and operating substantially as described.”

The combination has six constituents: (1) The lay not differing from the lay used in the ordinary loom, whose functions are to support the shuttle in its motions backward and forward. (2) A rigid shuttle-box, as distinguished from a sliding one, placed on the same side of the loom as the wire motion, and so attached to the lay that it partakes of its backward and forward movements. (3) The pivoted vibrating wire trough, which acts as a support to the wires. By means of the latch, and the reciprocating driving slide, the wires are drawn from the fabric into this trough, which oscillates towards the lay, transporting the wires into the proper position, where they are pushed out of the trough into the open shed of the loom. (4 and 5> The reciprocating driving slide and the latch, the former forcing the wire from the trough into the shed, and - the latter catching into-the head of the wire by a spring hook, drawing it again from the fabric into the trough. (6) The wire-box. which is a contrivance or receptacle for the heads of the wires, when they are inserted in the fabric. The box has a slot on its top, under which there is always the head of a wire when the loom is in operation. The nose of the latch drops into this slot and engages the head of the wire that lies nearest to the breast-beam of the loom, whence it is withdrawn to the trough. The wire-box has also other functions. It operates as a cam, disengaging the latch from the wire head after the wire has been inserted into the shed, and supporting the hook so that it cannot engage with any of the wires in the box while the hook and trough are passing from the open shed to the breast-beam.

The evidence hardly admits of a serious doubt but that the defendants have in[555]*555fringed this combination. The testimony of the complainants’ expert, Mr. H. B. Ken-wick, is explicit in the matter. After an examination of the looms in use by the defendant corporation, at their works in New Brunswick, and after producing two models, one, marked “P,” and representing the parts making up the combination referred to in the fifth claim of Webster’s patent, and the other, marked “D,” exhibiting the loom seen by him at New Brunswick, so far as it represented the mechanical elements or contrivances that are referred to in said fifth claim, he testified that one contained substantially all the parts embraced in the other; that they operated in combination in the same way, and produced the same effect. He said, referring to the model of the machine used by defendants:

“In this model, the lathe represented is an ordinarj' lathe, to which a shuttle-box is rigidly attached, so that it oscillates with the lathe. In it there is a vibrating wire trough T, which is long enough to support the wire — support that portion of it, which is not in either the shed or the fabric, or the whole of it when the wire is pulled out — and so oscillates as to transport the wire from the locality at which it was pulled out to that at which it is to be inserted, thus performing precisely the same duties that the wire trough performs in the Webster loom. It differs from Webster’s solely in the way in which it is mounted, so as to be capable of oscillating to the required extent. In Webster’s the trough is mounted on a vertical shaft or pivot. In the defendants’ loom the trough is mounted upon a horizontal shaft. But the two troughs are the same, and support and transport the wire in substantially the same way. The defendants’ loom has a reciprocating driving slide, which acts as a piston and pushes the wire out of the trough into the shed, and also carries the latch or hook, which pulls the wire out of the fabric into thé trough. This driving slide is identical, in all respects, with that of Webster. The defendants’ loom has also a latch or spring hook, which engages with a nick or depression in the head of the wire, and operates to pull the wire out of the fabric and deposit it in the trough. This latch is substantially identical in construction and operation with Webster’s latch. In the defendants’ loom there is likewise a wire-box, which contains the heads of the wires when they are inserted in the cloth, and along the bottom of which the heads of the wires slide, as in Webster's wire-box. The top of this box in the defendants’ loom, is so shaped that when the nose of the latch strikes the top of the box, the latch is lifted and the wire released from its grasp and left in the cloth; also, in such a way that it holds the latch lifted while the latch and trough are oscillating toward the breast-beam, thus preventing the latch from engaging with the wire head while it is so moving; and the top of this box has also a slot in it, which permits the latch or hook to drop so as to take hold of that wire which is nearest the breast-beam, in order that this wire may be drawn out of the cloth. The top of the Webster latch-box is constructed in the same way to produce these same effects.”

Instead of contradicting this testimony of the identity of the two machines, the defendants’ expert, Mr. E. S. Renwick, in effect corroborates it. He recognizes their difference in the mode of mounting and operating the wire trough, as Mr. H. B. Renwick did. But it is a significant fact that the able counsel of the defendants addressed no question to him which would test the accuracy of the direct testimony of the complainants’ expert, that, notwithstanding this difference in mounting, the troughs were the same, and supported and transported the wire in substantially the same way; and the responses made by the witness to the carefully-worded questions 7 and 8 show the reason why he was not interrogated upon the subject. After his examination of “Exhibit Dayis Model, J. G.
