A Motion Picture Machine of relatively simple construction adapted tor taking printing and projecting motion pictures as well as "still' pictures. It includes a casing and a frame removable therefrom, the frame carrying the operating mechanism and light-tight partitions, so that when the frame is inserted into the outer casing the latter will be subdivided into three compartments the outer two of which are the film chambers. 1192666 — M. Meushaw. A Motion Picture Taking Comera in which the lens is oscillated up and down by a crank movement while the film is continuously fed. It includes a rotary radial slit type of focal plane shutter which passes across an opening having inclined top and bottom edges. 1187986 — E. M. Goldsmith. A Reel for Ribbons which might be used for motion picture film. It comprises a huh on which are two heads, one fixed to the hub and the other mounted to turn thereon. 1190262— J. B. Carroll. Film Unwinding Apparatus for Motion Picture Projectors. The coil of film to be projected is placed in a horizontal cylindrical casting at the top of the machine and fed from its inner periphery instead of the outer, the inventor avoids rewinding of the film between successive projections. 1191069 — ■ C. Dawson. A Shutter for Motion Picture Projectors, which includes besides the usual sector, an auxiliary sector carrying a slitted portion and a nega tive lens which provide for a brief period of subdued light to avoid flicker. „ . . 1190354^ L. E. Wyble. A Safety Attachment for Motion Picture Projecting Machines. It includes a gravity actuated cut-off for the light which is held in inoperative position so long as the film is tight and unbroken. 1101224" N. Power. A Safety Device for Motion Picture Projecting Machines. It provides a cut-oEf for the light which automatically operates whenever the film remains stationary for an abnormal length of time. It includes a pivoted arm carrying rolls which bear against a loop in the film. Anyabnormal change in the loop will cause the arm to turn, which motion stops the machine and cuts off the light. 1190943— E. E. Norton. Talking Motion Picture Apparatus Comprising a Synchronized Motion Picture Projector and Talking Machine. The talking machine rotates a disc carrying a series of numerals which pass one a time beforethe eye of the observer. A corresponding set of numerals are carried by the film and are observable adjacent the disc numerals by means of a reflecting system. The machines are speeded so that the. numerals coincide. 1190370— J W. Billings. An Attachment for Motion Picture Cameras. At selected intervals, a conducting member carried by the main film closes an electric circuit,, thereby actuating the feed mechanism of a supplementary descriptive film. A phonograph could be similarly operated in synchronism. 1102094 — J J. Mouis. A Device for Synchronizing Motion Pictures and Music from Living Singers. Instruments or Talking Machines.

It is alleged the device can be run by dry batteries. 11S030S — M. P. Sullivan. An Apparatus through which Stereoscopic Motion Pictures may be observed. Pictures corresponding to a right-eye point of view and a left-eye point of view are alternately projected upon the screen. Thepresent apparatus is designed so that the observer will see only the righteye picture with the right eye and the left-eye picture with the left eye. It consists of a body having sight openings opposite the eyes of the observer and an electro magnetic shutter which opens and closes the openings alternately in synchronism with the projection of the pictures. The current for the magnets is controlled by commutators turned by the film feeding shaft. The shutter is shaped so that one of the sight openings is fully closed before the other oneis opened. «{ 1180494 — E. Schneider. An Adjustable Duplex Finder for Moving Picture Cameras. It includes a piano concave direct-vision finder and a second fiader for focusing, composed of a biconvex lens and a ground glass. The finders are pivoted so that they may be turned until the view therein corresponds to the view in the camera, thus correcting the error due to the difference in viewpoint of the camera lens and finder lenses. The degrees through which the finders are turned are determined by pointers and scales calibrated according to the distance of the object focused on. The distance of the object is determined by a scale on the ground glass finder. 1101321— W. H. Kunert. A Film Mending Device in which the two ends of a broken motion picture film are clamped with the perforations thereof, so spaced that when the pieces of film are cemented together they will cause no obstruction in the projection apparatus.
