Motography (Apr-Dec 1911)

July, 1911. MOTOGRAPHY 27 vancing roller ;;. Above the roller n is arranged in a suitable manner the window or aperture F in the standard a. The film travels in the well known manner through the window F over the advance or driving roller n against which it is pressed by means of guide rollers Mi W2. As the film frequently does not take up such a position in the window opening that the latter is exactly filled by a picture on the film, the said picture must be shifted upward or downward during the working of the kinematograph. The shifting in question is effected in the present case by raising or lowering the double armed beam to a certain extent by adjusting the screw c. As for instance, the raising of the beam (Fig. 4) would result in the rolling of the pinion / in the direction of the dotted arrow to a certain extent on the crank wheel, the advance of the Maltese cross would take place a certain time later than in the case of the normal position of the beam, as the pin h comes a little later in engagement with the Maltese cross 0 in accordance with the form or shape of the wheel /. As, however, the advance must always take place exactly at the same time as the closing of the shutter, v, the wheel h is secured to the other end of the beam, and when the latter is oscellated, the wheel h is advanced to exactly the same angular extent as the wheel f, as both the wheels engage at the opposite sides with the same wheel g. Consequently the closing of the shutter takes place, in spite of any shifting of the beam or of the film, always in exact synchronism with the advance of the film band. Fig. 5 shows the position when the beam is shifted downward. The advance then takes place a little earlier than during the normal position of the beam, and the closing of the shutter will then also take place earlier to the same extent, so that the advance of the film and the closing of the shutter again coincide exactly in the point of time. On the spindle i there is further mounted a flywheel k for the purpose of insuring a steady, uniform movement of the apparatus. The object glass ring t is secured to the window F in any well known or preferred manner. I claim 1. A kinematographic apparatus having a positive connection between the device for the adjustment of the film band in the exposure window, and that for the corresponding shifting of the shutter, in which the whole driving mechanism for the advance of the band and for the operation of the shutter, is mounted on a double-armed beam adjustable by means of a setting device and oscillating about the spindle of the crank or driving wheel, in such manner that on its one arm is mounted the toothed wheel or pinion driving the advance roller of the film by means of a Maltese cross and engaging with the crank or driving wheel, while opposite, on its other arm, is mounted the spindle of the shutter which is driven by means of a pinion engaging with the same crank or driving wheel. 2'. A kinematograph apparatus comprises in combination, a driving shaft, a lever mounted on said shaft, film advancing and shutter means operatively connected with said shaft for adjustment and operation and mounted on said lever, and means for shifting said lever to synchronously adjust said film advancing and shutter means. 3. A kinematograph apparatus comprising in combination, a pivotally mounted lever, film advancing means and shutter means mounted on said lever, mechanism operatively connected with said advancing means and shutter means for operation and adjustment thereof, and means for shifting said lever to synchronously adjust said advancing and shutter means.

The intent of this patent is to cover upon the type of picture film which is made up of a gelatine film carrying the silver images in it and faced upon both sides with celluloid or the equivalent. In producing the article of the invention, a web 10 of flexible transparent celluloid is coated with a gelatine film 11, exposed in a printing machine or camera, developed and dried, then varnished with a celluloid varnish to produce the coating 75. This is the well-known "waterproofed" film. The claims cover and protect the resulting film, no matter what the process by which it may be formed. They are as follows : 1. A transparency for the projection of moving pictures comprising a continuous photographic picture film interposed be tween a flexible transparent carrying web and a coating of substantially the same character as the web, the web and coating being permanently adhered to opposite faces of the picture film. 2. A transparency for the protection of moving pictures comprising a continuous photographic picture film carried by a flexible transparent web, the picture film being covered by a resistant film of celluloid varnish and of such a nature that scratches may be obliterated by a subsequent deposit of similar material. 3. A transparency for the projection of moving pictures comprising a continuous photographic picture film carried by a flexible transparent web having a marginal row of sprocketsengaging apertures, the picture film being covered by a resistant film of a celluloid varnish without closing the sprocket-engaging apertures of the carrying web and being of such a nature that scratches may be obliterated by a subsequent deposit of similar material. 4.
