Opinion

TOWNSEND, District Judge.

This is a bill in equity for infringement of letters patent No. 418,644, granted October 29, 1889, to T. Benfield, S. Aufhauser, and A. Milne, for a watch protector. The patentees originally filed in the patent office six claims covering the elements of the alleged invention, but upon citation of anticipations restricted the specification by disclaimer, and substituted a single claim for a combination, which was allowed, and is as follows:

“As a new article of manufacture, a watch protector, adapted to hold or contain a watch, and constructed of'highly magnetic metal, and in two sections, the latter being joined by means of a coiled spring, the inner surface of said sections being covered with plush or other soft nonmagnetic material, and their outer surfaces with japan, paint, or other like substances, substantially as set forth.”

The object of the alleged invention, as stated in the specification, is to provide an economical device which would prevent watch movements from becoming magnetized by electric currents, .and protect the watch from injury. This protector was of such size and shape as to allow the watch to fit snugly in it, and could be easily removed whenever the wearer had no opcasion to use it. The defenses are noninfringement, that the claim merely covers an aggregation of old elements, and that the patent is invalid in view of the state of the art.

Infringement is proved. The contention of defendant on this point, that the patent is limited to a construction of iron, is negatived by the language of the specification,' which describes the receptacle as constructed "of sheet iron or other highly magnetic metal,” or of “a piece of sheet metal, highly magnetic, and preferably sheet iron.” This limited construction, if supported, would be immaterial, inasmuch as the evidence shows that the defendant’s watch protector is not only an exact copy of complainant’s in external appearance, but that the metal used is, in character and operation, the same as that of the patent in suit, and is, jar_all [615]*615practical purposes, iron. Every essential element of the alleged combination is old, as complainant’s expert admits that, in view of the state of the art, to line such a protector with plush, or to cover it with japan, did not involve invention, and that the form of spring used was old. It is also admitted that devices for protecting watches from physical injury, and their movements from magnetic influence, were old. Patent No. 56,014, granted July 3, 1866, to W. W. Coveil, Jr., describes a watch protector of such size and shape that a. watch may fit snugly within it, made of brass or other metal, to protect the watch 1'rom external injury, and lined with soft material so as to prevent the case from getting scratched or worn, provided with a hinged spring, easily removed when not wanted, and capable of a construction which would permit the watch to be consulted without removing it from the protector. The only essential differences between it and the protector of the patent in suit were that, being designed for protection against pickpockets, and not against magnetism, it was provided with eyes and a pin, whereby it could be secured to the pocket of the wearer, and it was not limited in construction to highly magnetic metal. The differences in finish and in details of construction of spring hinge and covering are, for reasons already stated, immaterial. Patent No. 93,246, granted to W. O. Sumner,'August 3, 1869, for a watch protector, shows a somewhat similar contrivance, the patent office model of which is of iron.

Complainant, in his specification, disclaims the devices formerly used for protecting watch movements from magnetism, and which were originally cited as anticipatións. It was well known in the art, long prior to complainant’s alleged invention, that sheet iron, in the form of cases or rings surrounding an object, would prevent it from being affected by magnetism. Devices of this character, to protect compasses, are shown in Kline patent, No. 16,845, and Pender patent, No. 44,451. But patents Nos. 289,642, granted December 4, 1883; 812,458, granted February 17, 1885; and 365.-985 and 365,990, granted July 5, 1887, to C. K. Giles; and patent; No. 403,211, granted May 14, 1889, to H. P. Pratt, — show the practical application of this knowledge to watch protectors. The Giles patents described various kinds of protectors, among them being one (No. 312,458) where the watch case itself was made up with a sheet of iron between the case plates of gold or silver. In patent No. 289,642, Giles describes the disastrous effect upon watches of dynamos and other electrical apparatus, and states as follows;

“It is well known that when watches are brought near to powerful magnets their utility is entirely destroyed, as the many parts of the movement become magnetized, and so the regularity of the movement is entirely destroyed. At the present time, when powerful dynamo machines are in use all over the country for various purposes, the liability to this injurious disturbance in watches is greatly increased, for the magnets of these machines are frequently so powerful that persons coming, near these machines will find the watch they carry affected, as described, by the magnet. It is an object of my Invention to overcome this difficulty, and completely protect the watch from the deleterious influence of magnets, so that it may be carried into the presence of dynamo machines, or into the presence of magnets elsewhere, with perfect security against injury; also to shield the watch from the mag[616]*616netism and magnetic currents of the body. This result I accomplish by surrounding the works or the watch with a complete shield of highly magnetic metal, or an alloy or combination of metals which, in common language, may be said to absorb or turn aside the magnetic currents, thereby preventing their reaching the works of the watch movement.”

Although the patentee describes such protector as a box, or case, preferably designed to go inside the regular case of the watch, he also suggests, as above shown, a case for the watch itself. He also states as follows:

“I have thus described one way in which my invention may be carried out practically, but I do not limit my improvement to this particular mode of embodiment. • The shield may be of any suitable form and construction, provided only, it so nearly incloses the watch as to accomplish the object explained; and it may be made of any metal or compound which is adapted to secure the result described.”

I have not overlooked the evidence that the claimed anticipations are mere paper patents, which have never been successfully used. But such objection is insufficient where the modifications merely consist in matters of detail which could have been made by any mechanic, or do not require invention. Pickering v. McCullough, 104 U. S. 310. The most that can be claimed for this patent is that it is for a more economical device, with higher finish, or greater beauty of surface, than had been heretofore made, and that it has been extensively adopted and used by the public.' But it is well settled that these circumstances are not, in themselves, sufficient to constitute invention. Ansonia, etc., Co. v. Electrical Supply Co., 144 U. S. 11, 12 Sup. Ct. 601. In Duer v. Lock Co., 37 Fed.
