22 MOTOGRAPHY Vol. V, No. 4. opposite directions, and then converging them in a manner to coincide with the said red rays upon a screen, maintaining equal focal distances for the light rays. of the three colors, and projecting the rays of the three colors directly upon the screen through optical media. The descriptive matter of patent No. 973,962 differs but little in substance from that of the patent No. 973,961, being a divisional application of the original for the purpose of carrying additional claims so dif 976,143. ferent in nature that the patent office would not permit them to be contained in the same issue patent, yet all based upon the same subject matter. The claims of patent No. 973,961 are : 1. Apparatus for projecting pictures in natural colors comprising a film having a plurality of transversely arranged like images of the object or scene to be reproduced, in three primary color values, a plurality of projecting lenses, means for axial and rotary adjustment of said lenses, and means interposed between said film and said lenses for diverging light rays transmitted through the outer images in opposite directions and converging them in a manner to coincide with light rays passing directly through the central image and central lens. 2'. Apparatus for projecting pictures in natural colors comprising a film having a plurality of transversely arranged like images of the object or scene to be reproduced in three primary color values, a plurality of projecting lenses, means 976,954. for axial, lateral, and rotary adjustment of said lenses, means interposed between said film and said lenses for diverging light rays transmitted through the outer images in opposite directions and converging them in a manner to coincide with light rays passing directly through the central image and central lens, and means for adjusting said reflectors in vertical and horizontal planes. 3. Apparatus for projecting photographic images in natural colors comprising a tri-part film having like images of each pose of the object or scene to be projected in juxta position and the images having different primary color values, means for projecting rays of light from a suitable source through said film, a plurality of projecting lenses corresponding with the film images, and means interposed between said film and said lenses to first diverge and then converge the light rays passing through the outer film-images. No. 976,067. Fire-Proof Receptacle for Motion Picture Films. George J. Gilmore, Chicago, 111. In a main cabinet io are a number of shelves 20, 20, upon which film reels or magazines 21, 21, may be laid. Each shelf 20, 20, has a separate door 2g, 23, and the main cabinet 10 has a door 13. All the doors are so hinged that they close by gravity, and are so blocked that they cannot be opened so far that they will stay open. At the bottom of the cabinet 10 is a humidifier 22. All the walls and the main door 13 are made double, as are also the shelves 20, 20. No. 976,143. Stage Illusion. J. G. Bostock, New York, N. Y. This device may be used either for direct display to an audience or for the making of motion picture films. It is particularly adapted to the manufacture of picture films of the trick picture class. In connection with a stage setting of proscenium arch 1, footlights 2, and drop curtain 3, there is shown a frame 4, supporting a painted scene 5, having a rectangular opening at 6, the bottom part of the scene 977,466. curving at 7. Toward the back of the stage is a back scene 8. A negative lens, or double-concave lens, p, located behind the opening 6, shows the figure 10 to the audience in reduced size, as indicated by the small figure in dotted line near the negative lens p. A side light for illuminating the figure 10 is shown at 11. The total effect is the illusion of extremely small actors performing, either before an audience or upon the motion picture screen. No. 976,896. Amusement Apparatus. W. W. McFarland, Denver, Colo., assignor of parts to H. L. Weber and Theodore Nollenberger, of same place. The device is intended for amusement parks, and is a simulation of an air-ship, which is drawn up an elevator shaft and permitted to traverse a comparatively long spiral track in descending. No. 976,954. Motion Picture Camera. Alexander Ferdinand Victor, Toledo, Ohio. A camera for taking pictures of toy size, arranged spirally upon a circular disk of photographic film. The same device may be used for projecting the prints from the pictures, or may be used for viewing the prints by direct vision.
