242 F. 267 | 6th Cir. | 1917
Suit for infringement of United States patent No. 1,099,715 to Myers, June 19, 1914, on light controllers. The device of the patent is specially adapted to automobiles; its objects are to increase light intensity and decrease objectionable light dispersion. These objects are accomplished by silvering the lower portion (about one-half) of the ordinary electric light bulb seated in the usual spherical or parabolic reflector, whereby the light is projected from one side of the silvered part of the bulb, acting as a reflector, toward the opposite side of the main reflector, thus increasing the intensity of the rays which normally proceed from the light itself in the same direction. When the silvered portion of the bulb is in the usual lower position, the light is reflected therefrom upward to the main reflector and thence downward upon the road, and approaching drivers and pedestrians relieved from confusion due to blinding rays otherwise projected upward from the lower side of the main reflector. The patent also discloses a method whereby the lamp, having a rotatable stem mounted in the main reflector, may be rotated by the driver from the seat, and the
The alleged infringing device differs, however, from the disclosure of the patent in these respects: The electric light bulb is incapable of rotation in the socket of the main reflector except manually and after releasing a set screw which normally prevents rotation; and it has no means for adjusting, from the driver’s seat, the bulb reflector and the main reflector relatively to each other, and thus for varying the direction of ray projection. As used in the bullet headlight, which is the alleged infringing use, this result can be accomplished only by manually opening the glass front of the headlight, manually releasing the set screw mentioned, and then manually turning the bulb in its socket; or, after releasing another series of set screws securing the main reflector to the rim of the glass front, manually detaching the adjustable shell from, or turning it upon, the glass bulb, and readjusting it manually in the desired position. Manifestly the method first stated would be the natural one. This adjustment thus cannot be effected from the driver’s seat or while the automobile is in motion. The pivotal question is whether this capacity for manual adjustment responds to the call in the claims for “deflectable light-projecting means,” “means for adjusting the reflectors relatively to each other,” and “adjustment means for the light in varying the direction of ray projection.”
We cannot think that a capacity for adjustment by manually removing the shell from the bulb and manually replacing it in another position is the equivalent of the means for adjusting and deflecting within the proper interpretation of the claims in question. Such capacity for manual adjustment would be of little practical value. In our opinion the means called for by the claims are operative means; manual means are mechanical only. This conclusion is fortified by the decision of Judge Teamed Hand in a case brought by this plaintiff for infringement of the patent here in suit (Quinn v. Faw [D. C.] 235 Fed. 166), which has been affirmed by the Circuit Court of Appeals for the Second Circuit.
So far as appellee’s rights are concerned, this suggestion is without
The decree of the District Court, finding infringement of claims 2 and 3, and awarding injunction and accounting with reference thereto, is reversed, and the record remanded to that court for further proceedings not inconsistent with this opinion. Appellants will recover their costs of this court, except the item above mentioned.
“2. Deflectable light projecting means embodying the combination with a first projecting reflector of a light therein having fixed therewith a second reflector directed toward the first reflector, and means for adjusting the reflectors relatively to each other whereby a portion of the light field of the first reflector may be intensified at the sacrifice of other portions of the light field of the first reflector.”
