We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
ORIGINAL PETITION, EXHIBIT 9. 125
the wheels 5, Figs. 1 and 2, enter for the purpose of positively advancing the film. When the film is narrow, it is not essential to use two rows of perforations and two feedwheels, one feed-wheel being sufficient. Said wheels are mounted on a shaft 6, which carries a loose pulley 7 — that is, a pulley frictionally connected to its shaft and forming a yielding mechanical connection. This pulley is driven by a cord or belt 8 from a pulley 9 on the shaft 10, which shaft is driven by means of the beveled gears 11 12. The wheel 12 is preferably driven by an electric motor 13, which when the apparatus is in use is regulated to run at the desired uniform speed, being controlled by the centrifugal governor 14 and the circuit-controller 15 in a well-known manner. On the shaft 10 is another pulley 16, which is connected by a cross-belt 17 to a pulle}^ 18, also frictionally connected to its shaft, and which carries the reel to which the tape is connected in casing 2. The film passes from the casing 1 through a sUt formed by the edge 19 and the sliding door 20, which is normally thrown forward by the spring 21, Fig. 2, with sufficient force to clamp the film and hold it from ovement. When the door 20 is retracted by pulling on the rod or string 22, which is connected to the arm 22', the film is liberated and allowed to advance. Film-case 2 is provided with a similar door, but the device for moving the door is not illustrated. This arrangement of the sliding door not only holds the film, but it tightly closes the casing, thus excluding light and protecting the sensitive film. The casings or boxes 1 2 are removable, so that they, with the inclosed film, may be taken bodily from the apparatus. The shaft 6, heretofore referred to, is provided with a detent or stop-wheel 23, the form of which is most clearly shown in Figs. 3 and 4. The wheel 23 is provided with a number of projecting teeth 24, six being shown, which teeth are adapted to strike successively against the face of the cooperating detent or stopwheel 25 on the shaft 26, which is the armature-shaft of the motor or a shaft which is constantly driven by the r otor. The wheel 25 has a corresponding number of notches 27 at regular intervals around its periphery. These notches are
