Motography (1912)

November 9. 1912. MOTOGRAPHY 363 as the lever is moving continuously and the him is at rest between its successive steps during projection. Mr. Davis effects an improvement in this feature by applying a guide attached to the framing carriage and placed between the him and the aperture plate so that when the framing carriage is moved the film guides move on both sides of the film and the film is not dragged over one of them. The patent contains six claims which include not only the feature above described but also the combination of that feature with a spring mounted roller for guiding the film. Xo. 1.036.730. Method of Cutting Out Contour Bands or Stencils Used in Coloring Kinematograph Films. Carlo Sciamengo. Turin. Italv. Filed November 2. 1911. As has been described in previous issues of Motog consists in passing over the celluloid band a point heated to a temperature sufficient to cause the desired contour to be cleanly cut out. 2. The method of cutting celluloid, which consists in subjecting it to the action of a tool or point heated to a temperature sufficient to soften the celluloid. No. 1.037.112. Moving Picture Machine. George \Y. Bingham. New York. X. Y.. assignor to the Bingham Manufacturing Company. Filed September 29. 1910. The invention relates particularly to the intermittent mechanism or film stepping mechanism of a motion picture projecting machine. In the drawing of the patent the film shown is not provided with sprocket holes and the projecting machine is not provided with sprockets. The stepping effect is secured by upper and lower oscillating film guides. The patent is issued with 36 claims which constitute brief but accurate descriptions of the principal features "Pals." November 2. Copyright 1912, American Film Mfg. Co. raphv. the well-known colored films usually referred to as "hand colored films" are really colored by stenciling the colors upon the film ; the stencil, however, is produced by hand cutting. The invention for which this patent has been issued to Mr. Sciamengo consists in an improved method of cutting out the stencil bands. By the improved method. the stencil to be cut out is traced over by a point heated to such a temperature that the celluloid of the band isoftened without taking fire. By this means, the desired contour may be cut out neatly, with great accuracy and smoothness. The point may be heated by an electric current, or in any manner, and is mounted in a handle. The patent is issuer! for the method of doing the work, and not for the means or particular form of hot point used. Quoted below in full are the two claim of the patent : 1. The methods of cutting out contour or stencil hands of celluloid for use in coloring kinematograph films, which of the invention. The following are reproduced as typical : 1. In a moving picture machine, film advancing means comprising film guides through which the film is passed, a common support for said guides, and means for imparting an oscillator} movement to the support and thus to the guides carried thereby. 9. In a moving picture machine, upper and lower flat tuhular guides for the reception of the film, a common support for said guides, and means for oscillating the support and guides carried thereby, whereby an intermittent advancing movement will be imparted to the film. 12. In a moving picture machine, upper and lower film guides adapted for the reception of the film, means for oscillating said guides to impart an intermittent advancing movement to the film, and a fixed though relatively adjustable guide associated with the upper movable film guide. 21. In a moving picture machine provided with an exposure opening, flat tubular film guides mrough which the film passes, located above and below the exposure opening, a common support for said film guides, and means for oscillating said support and the film guides carried thereby with a comparatively slow upward movement and a relatively quick downward movement.
