ORIGINAL PETITION^ EXHIBIT 9. 127
34 is a device for adjusting the camera-lens toward or from the fihn, and 35 is a device by means of which the operator can focus the camera on the object to be photographed.
Although the operation has been partially indicated in the description of the apparatus, it will now be set forth more in detail.
The apparatus is first charged with a sensitive tape-film several hundred or even thousands of feet long and the motor is set in operation. Since the spring 21 causes the door 20 to clamp the film, as already described, the loose pulleys 7 18 slip without pulling said film along; but when a moving object— for example, a man gesticulating — is placed in the field of the camera and the handle 22 is pulled the film is released and the pulleys operate to pull the same along. At the same time the reel in case 2 is rotated to wind up the film, thus transferring it from the reel in case 1 to the reel in case 2. This movement is intermittent, the film advancing by very rapid steps, which are definitely and positively controlled by means of the peculiar detent or escapement described, and a photograph is taken after each step.
While I do not care to limit myself to any particular numner of steps per second, there should be at least enough so that the eye of an observer cannot distinguish, or at least cannot clearly and positively distinguish, at a glance a difference in the position occupied by the object in the successive pictures, as illustrated in Fig. 7. A less speed in taking the pictures will cause a trembling or jerky appearance in the reproduced picture. When the movement of the object being photographed has ceased or the desired number of photographs has been obtained, the apparatus is stopped. The film is suitably treated for developing and fixing the pictures, when it is ready for use in an exhibiting apparatus. It will be observed that all the photographs on the film are taken through the same camera-lens, which results in such a uniformity of photographs as would be unattainable were the photographs taken through different lenses.
