121 F. 129 | U.S. Circuit Court for the District of Southern New York | 1902
Suit is brought to enjoin infringement of complainant’s United States letters patent for a theatrical appliance —No. 643,493; February 13, 1900; application filed November 10, 1899. The claims relied on are:
“(1) In stage appliances, an open-work base, streamers attached to said base, and means for directing currents of air to the base and for illuminating streamers through the base.
••(21 In stage appliances, a foraminated structure, streamers connected thereto, fans beneath the foraminated structure, arranged to concentrate air-*130 currents thereon, and an illuminating device, the delivery whereof Is directed to the aforesaid foraminated structure.”
By this appliance, as the specifications point out, “the effect of a fierce fire may be produced upon a stage, or wherever else desired, without the possibility of injury to the surroundings, or to any person appearing to be in the midst of the flames and apparently handling the tongues of fire, or moving in close proximity thereto.” “The stage is provided with an opening, at which opening a gridiron or screen is secured, serving as a partial cover for said opening.” -Strips of a translucent or a transparent fabric are fastened at their lower ends so as to come over the meshes of the gridiron. They are “preferably tapering, although they may be given any desired shape.” They are of colors approximately the color of flame, are entirely free above the point to which they are attached, and are capable of waiving, fluttering, or curling when subjected to a suitably directed blast of air. This blast of air is produced through the medium of fans, whose position may be changed as may be found necessary to direct the streamers in a proper direction. The streamers are placed sufficiently close together to collectively form a column or volume of strips when the strips are under the influence of the air-supply, but the spaces between the said strips are sufficiently great to permit each individual strip to wave independently in front of or at the back or side of an adjacent strip. The illusion of fire is produced by directing rays of light upward through the screen or gridiron, and upon and through the mass of waving strips. Various colors or shades of color may be imparted to the light supplied to the strips or streamers, thus indicating the changes of colors in a leaping flame. The effect of sparks is obtained by introducing small bits of paper, cardboard, or the like, suitably colored, between the currents of air and the screen or gridiron, whereupon the said currents of air will carry these small pieces of colored material up through the meshes of the gridiron, and as soon as they are freed from the influence of the air blast the said pieces will fall to the stage, where their smooth surfaces and glittering color will continue to sparkle when the light is turned on or changed on the screen.
Defendant calls attention to the circumstance that the patent has never been adjudicated, and is of such recent date that long acquiescence cannot be shown, as sufficient ground for refusing preliminary injunction. The practice referred to is followed in this circuit, but only in cases where there is some question as to the validity of the patent. When the specification shows that, assuming facts of common knowledge, it will probably need some affirmative evidence to indicate the presence of invention, or when some testimony put in by defendant as to the prior state of the art, slight though it be, indicates that there may be some arguable question as to validity, or as to a construction of the claims broad enough to cover the device complained of, then preliminary injunction on affidavits is refused. But where the patent appears to be novel, useful, and ingenious, and there is no evidence at all assailing its validity, the presumption arising from issue of letters patent will be sufficient to warrant injunctive relief. The same rule should apply where the sole evidence as to prior art is wholly unpersuasive.
The patents to Sherwood (661,426) and to Carter (662,708) are both subsequent to complainant’s; the respective dates of application being July 31, 1900, and January 22, 1900. There is no evidence produced on this motion of knowledge and use prior to the date of complainant’s application, and the circumstance that one or both of the subsequent patentees last above named has brought or threatened suit against defendant is no answer by him to the present application. Infringement is entirely clear, and a preliminary injunction should issue. In view of the circumstance that defendants have invested a great deal of money in the production of a play in "which the representation of a raging fire is a prominent feature, a reasonable time should be allowed them to substitute some of the earlier appliances for those of the complainant as the means of producing such éffect. The operation of the injunction will therefore be suspended 10 days from the signing of the order. This decision is without prejudice to a motion to dissolve the injunction should defendant be able to produce any prior patents or publications which may indicate that the novelty or patentable invention of the complainant’s appliance is fairly questionable.
