The patent in suit relates to folding cameras of the familiar type, adapted to take photographs upon a film rolled upon reels mounted within the casing of the camera and fed from the supply reel to the take-up reel step by step as the pictures are taken. There were devices for the automatic winding of the film before folding cameras were in use, and it had long been realized that if, by reason of any carelessness, the film was not advanced after operating the shutter before another picture was taken, two' exposures would be made upon the same section of the film, and likewise, if the film was advanced after taking the picture, and the operator subsequently forgot that this had been done, and advanced it again, one section of the film would be wasted.
To solve these inevitable difficulties arising from carelessness of operation, it had been an invention of long standing to provide a spring motor in box cameras for winding off the film step by step', and to release the spring motor each time the shutter was operated. The United States patent, No. 506,210, to R. G. Barrill, issued October 10, 1893, illustrates an automatic wind connected with the shutter in a box camera. In this patent, when a lever is pressed lengthwise, a disc known as the shutter leaf is revolved, followed by the operation of a spring motor to wind off a section of the film. The still earlier patent, No. 417,871, to H. Laney, issued December 24, 1889, shows a lever in a box camera, the depression of which allows a spring to rotate the shutter. The shutter during its rotation operates a second lever, to release a third lever that drives the film.
When the box camera was succeeded in popularity by the folding camera, it was to be expected that the general features which had been discovered to be advantageous in box cameras would be employed, so far as practicable, in the folding camera.
By folding camera is meant a camera with an opening in its front wall in which a rectangular platform, known as the hinged front, is pivotally mounted. This front may be turned upon its hinge to a horizontal position, and the shutter may be drawn out over the platform thus provided; the bellows expanding as the shutter is so moved, to maintain the light-tight passage from the shutter hack to the film.
Osteen, the patentee in this case, sought to apply an automatic wind for the film under the control of the shutter to a folding camera. He proposed to use a spring motor for feeding the film, as had long before been done in box cameras, and proposed an operating connection between shutter and motor, as others had done before. But not only was the application of these ideas to box cameras well known, but, when attempting to apply them to folding cameras, Osteen entered a field already crowded. When he attempted to apply these old elements to a folding camera, he had to make some provision for folding the parts connecting the shutter and motor, as the hinged front of the camera was pivoted into a closed position.
But the Johnson patents, Nos. 1,083,743 and 1,166,763, had already disclosed pneumatic means for operating the shutter and governing a spring motor to wind off the film in a folding camera. These connecting means were foldable, and mounted in part upon the platform and in part upon the easing of the camera.
The third Johnson patent, No. 1,103,418, granted July 14, 1914, not only related to a folding camera having an automatic motor wind under the control of the shutter nieehanism, but employed rigid mechanical connections, instead of pneumatic tubes or flexible wires, to furnish interconnecting parts. It may be seen from the drawings that the forward end of shaft 44 has universal joint 45.' This collapsible shaft served to operate the shutter mechanism and was connected with the spring motor. The telescopic and universal joints made it possible to move the shutter out from the platform to the operative position and back into the easing to fold the camera. The universal joints are for the same purpose as the ruler joint of Osteen’s lever, and the shaft is mounted partly upon the hinged front or platform and partly upon the casing.
There was, lastly, in the prior art the patent to Brauner & Rosen, No. 1,253,205. The application for this patent was nearly a year before Osteen’s patent was applied for, so that it was prior art, under Milburn v. Davis-Bournonville Co., 270 U. S. 390, 46 S. Ct. 324, 70 L. Ed. 651. This Brauner & Rosen patent shows a sliding rod operating in a guide and projecting along the front of the folding camera. It is connected through the medium of a gear and associated elements with the flexible wire which leads to the shutter mechanism. The sliding rod connects the flexible wire with a reciprocating bell-crank lever that operates the mechanism to release the spring motor so that the film is wound upon the take-up reel. In this patent the mechanism connecting the releasing means with the shutter are foldable, and they are carried partly by the body of the camera and partly by the hinged front.
Such being the state of the art in respect to devices in folding cameras for an automatic wind for the film under the control of the shutter, Osteen obtained his patent on August 15,1916, and has secured a decision from the District Court that claim 2 is valid and infringed. This claim reads as follows:
“In a camera, a body, a hinged front therefor, a shutter supported on said hinged front, a film-receiving spool rotatably mounted in said body, means normally tending to rotate said spool, means to lock said spool against rotation, means for releasing said locking means, and foldable means carried partly by said body and partly by said hinged front connecting said releasing means with said shutter for actuating the latter.”
If the terms of this claim be taken as they read, the plaintiff is confronted with the fact that it is anticipated by Johnson and by Brauner & Rosen. He consequently seeks to exclude “pneumatic means” in interpreting the words “foldable means,” so as to avoid the first Johnson patents, and in the same way to exclude “flexible means,” in order to escape the Beyerlen and Moore patents. Having thus limited himself by exelusion to a rigid mechanism, he is met by the shaft of the third Johnson patent, with its universal joint, and by the rod and bell-crank lever of Brauner & Rosen. To avoid this prior art the patentee must practically confine himself to the structure specifically disclosed in his patent. But, if he does this, the defendant does not infringe. Its device follows United States patent, No. 1,268,805, to Topliff, G. Bommann, and E. C. Clark. The lever which it uses is not foldable, for it has nothing like the ruler joint of the patent in suit on which it may fold itself, but has a solid lever pivoted on the body of the camera. It therefore, does not fold, but swings as a whole, and likewise is not “carried * * * partly” by the hinged front, as claim 2 specifies.
Claim 2 was originally claim 8 in the patentee’s application, and was rejected by the Patent Office upon the Beyerlen patent.
This patent showed a flexible wire connection for operating the spring motor, carried solely by the body portion of the camera. Claim 8, which before the amendment had read “means connecting said releasing means with said shutter for actuating the latter,” was changed so as to read “foldable means carried partly by said body and partly by said hinged front, connecting said releasing means with said shutter for actuating the latter.” After obtaining the allowance of his claim by the insertion of these new elements, the patentee cannot now be heard to insist that the “means” need not be foldable, and need not be carried partly on the hinged front.
Furthermore, the claim reads so closely on the Brauner & Rosen device that there
It is, moreover, to be noted that no cameras have ever been manufactured under plaintiff’s patent, and he seems to have shown no adequate experience in such matters. He testified that, when he 'took out the patent, he was in the “barber business,” and at the time of the trial was “in the theater business.” The rough device, which he made in 1915, he testified was not made in accordance with the drawings of his patent. It is quite unlikely that a man with such experience could have contributed a meritorious invention t'o a technical and complicated art, and, at least so far as the claim in suit is concerned, there would seem to be no evidence that he ever did.
The decree is reversed, with directions to dismiss the bill, because of invalidity and noninfringement.
