Opinion

NIXON, District Judge.

The pleadings in this case show, that an original bill of complaint was filed against the defendants on the 13th of July, 1872, for an infringement of the original patent; and that an extension of the same having been obtained, pending the suit, on application to the commissioner of patents, the supplemental bill was filed February 5, 1874, setting forth the fact. The bills charge, that the defendants have infringed the said letters patent, originally granted to Hezekiah Conant, for “improvement in machines for winding thread on spools,” numbered 26,415, dated December 13, 1859, and ante-dated June 22, 1859, and extended June 21, 1873, for seven years from and after the expiration of the first term thereof.

The defendants in their answer deny: (1) That the threading machines used in their manufactory contain the inventions recited in any of the claims of the complainants’ patent. (2) That Conant was the original and first inventor of what is claimed in his patent, having been anticipated by certain enumerated English patents. And (3) they claim that the thread-winding machines used by the defendants were the invention of one William Weild, to whom English letters patent were granted January 22, 1858; that said invention was prior to Conant’s; and that the defendants paid royalty to the owner of the Weild patent.

At the hearing no stress seems to have been [44]*44laid upon the third defence, to wit, the alleged older invention of Weild—it appearing in the-proofs that the patent, although granted on the 22d of January, 1858, was not enrolled until the 22d of July following, and foreign patents are not admissible as evidence .against an American patent, anterior to the date of their enrollment.

The complainants’ patent has reference to an improvement in machines for winding thread on spools, and exhibits six claims. Two models were produced on the argument marked “Complainants’ Exhibits 5 and 6,” and the counsel admitted that the defendants had used and were using machines containing the features represented in these models. The complainants insist that these machines contain the invention set forth in the first, third mid fourth claims of the Conant patent. In the specifications of the patent, Mr. Conant says, that the object of his invention is to wind thread upon spools, with regularity and precision, layer upon layer, and each filling the whole length of the spool, without any attention on the part of the operator, further than to remove and replace the spools; to ■cut the thread and to fasten it when the spool is full; and to attach the thread to a fresh spool and set the machine in motion; and he thus describes the mechanism, which is claimed to be infringed by the defendants: “The nature of the first part of my invention consists in combming a pattern cam or traverse charger with nuts and right and left-hand ■screws or their equivalents for the purpose, the operation of the combination being such, that a thread guide shall have its motion reversed and, its length or distance of motion regulated automatically,” etc. “The nature of the third part of my invention consists in combming with a pattern cam, and right and left-hand screws and traversing nuts, a stop motion, substantially such as is hereafter specified, so that the whole apparatus shall be brought to rest when the bobbin is completely filled. The fourth part consists in making the lips of the levers that actuate the screw nuts or their equivalents, for the purpose they serve, adjustable, so that different lengths of spools may be wound properly by the same traverse charger.”

He states his claims as follows: “(1) The combination, in the maimer set forth, of a traverse charger, with right and left-hand screws, and with nuts which are alternately in gear with such screws, the combination operating as a whole substantially in the manner and for the purpose described.” “(3) A stop motion, substantially as described, for ■causing the machine to come to rest when a spool is filled, in combination with automatic apparatus, substantially such as set forth, for regulating the length of motion and change of direction of motion of a guide, through which thread is delivered on to a bobbin or spool. (4) Adjustable lips, substantially such as set forth, in combination with a traverse charger, whereby spools of different lengths may be wound by the use of the same traverse charger.”

The claims are all for combinations of mechanism for the production of specific results in the winding of thread upon spools. The elements of the first, are right and left-hand nuts, right and left-hand screws, and a traverse charger. The prior use of such nuts and screws, and of a traverse charger is admitted. The two former are found in the Wibberly patent, and the latter in the Young patent, both of which are English patents and antedate the complainants’. The question here is whether their combination is new. Old instrumentalities are patentable, when combined for the first time, in such a manner as to produce new and useful results.

The defendants insist that this claim is anticipated both, by the Wibberly patent and the Young patent; inasmuch, as in the former, the spool itself, when the machine is in operation, performs all the functions of a traverse charger, and, in the latter, there is an independent traverse charger, with which the thread guides are connected, so that each thread guide is caused to move to and fro, or traverse along its respective spool or bobbin.

It is not necessary to stop to inquire whether the spool in the Wibberly invention, is an equivalent for the traverse charger in the complainants’ patent; for a specific traverse charger, in connection with right and left-hand nuts and screws, appears in the Young patent If we _ should give the broad construction to the claim, insisted upon by the complainants, it is clearly anticipated by the Young invention, where the combination of equivalent instrumentalities appears. But it does not thence follow that the claim is void. The inventor has changed the mechanism so as to produce new and valuable results. His shaper or traverse charger is of peculiar construction, whereby the length of each succeeding traverse is not determined by the diameter of the barrel of the spool, or by even the presence of the spool upon the spindle, as in the Wibberly and Young machines,but by the varying lengths of the ribs on the periphery of the wheel. Whether the defendants’ machines infringe the claim as thus construed will be considered hereafter.

The constituents of the third claim are the several elements of the first claim, in combination with automatic mechanism for a stop motion, which, by moving the belt from the driving pulley to a loose pulley, when the bobbin is nearly filled, brings the whole apparatus gradually to rest by its own friction. If this claim should be construed to include every stop motion, or means of stopping the machine with automatic apparatus, it would be void for want of novelty. The stop motion is not new per se, nor was Conant the first to combine a stop motion with a traverse charger, so as to stop the machine automatically. Wibberly does this, not by the shifting of the belt, but by means of a brake, [45]*45•which is brought suddenly to bear upon the parts of the apparatus connected with the winding spindle.

Avoiding, then, the construction which renders the claim invalid, let us inquire what is the scope or purpose of the invention, as exhibited in the claim. It is a combination with a combination, and the patentee sets forth in the specifications of his patent, the methods which he employs, and the results he obtains, by their union.
