Blakey v. National Mfg. Co., 95 F. 136

Blakey v. National Mfg. Co.

95 F. 136 | 3rd Cir. | 1899

DALLAS, Circuit Judge.

This is an appeal from a decree of the circuit court of the United States for the Western district of Pennsylvania, refusing a preliminary injunction to restrain the alleged infringement by the appellees of the first claim of letters patent of the United States No. 440,168, dated November 11, 1890, which claim is as follows: “(1) The device for protecting the screw-threaded ends of pipes, consisting of a band provided with flanges on each end of the band, and adapted to engage the screw threads of the pipe, substantially as set forth.” The only question which we have felt ourselves called upon to consider is that of infringement, and we do *137not, in the present situation of the case, deem it desirable to enter upon a discussion of it. It is sufficient for the present purpose^ to say, as has often been said before, that a preliminary injunction should never be awarded where the right is doubtful, or the wrong uncertain, and that the infringement here charged has not been clearly esiahlished. American Nicholson Pavement Co. v. City of Elizabeth, 4. Fish. Pat. Cas. 189, Fed. Cas. No. 312. Consolidated Electric Storage Co. v. Accumulator Co., 5 C. C. A. 202, 55 Fed. 485; Van Camp Packing Co. v. Cruikshanks Bros. Co., 33 C. C. A. 280, 90 Fed. 814; Williams v. McNeely, 56 Fed. 265. The question of infringement, as it was presented in (he prior adjudications, which have been brought i.o the attention of the court, is not identical with that which arises upon this record. It is, of course, possible that upon Anal hearing the complainants may appear to be entitled to the relief which they seek; but that, upon the proofs as now submitted, the court below erred in refusing a preliminary injunction, the only legitimate purpose of which is to preserve the existing state of things until the rights of the parties can he thoroughly investigated, we cannot adjudge. The decree is affirmed.
