2038 Motion Picture N ei New Motion Picture Camera {Continued from page 2030) the film from the front, O2 lightens it through the prism from the rear. In front of and behind the film blinders are put up. Of course, it is also possible to blind in the usual way in front of the objectives. 1 Sketch No. 1 The pictures of the two objectives are now side by side as seen in Sketch No. 2. In this way it is possible for the actor to see his vision and harmonize his actions with that of the vision during the photographing of the set, a feat which could not be done in the past. The numerous possibilities of this attachment would lengthen this article inordinately, still an expert can readily see its possibilities, as for instance, by the use of objectives with different focal distance. It will only be mentioned that this arrangement gives no loss in light and that it is possible by changing the two rotating blinders to reach whatever light intensity is desired. As the Superimposed Picture Attachment can be removed, it is only on the camera in case of necessity and does not disturb the apparatus when in ordinary use. Objective Mounting. As already mentioned, the objectives are mounted in a holder, which is fixed to the picture glass plate and the objectives can be changed in the holder. The objective is located in the interior of the apparatus. The front door of the camera is provided with a ring in which the blinders and the tube for long focal distances can be attached. The movement for the exact focus and the iris Winder for the objective is operated from the rear of the camera by the levers S and I which move over registering dials. Rotation Locking Device. The rotation locking device has an opening of 170° which can be diminished during the photographing to 0°. This device is operated by means of the lever R on the back of the camera. The possibihty of increasing or diminishing the opening during the operation of the camera makes it possible to blind as much as wanted beyond the limits of the iris blinder. (See Fig. 4-) Snatcher. The snatcher is quite a new arrangement. It works simultaneously over and under the picture glass and in such a way that when the handle of the crank is moved forward only the lower part operates and when the machine is reversed only the upper part works. In this way, the film roll will only be drawn ahead but never pushed by either a reverse movement or a forward movement. As the roll is an element only for tension this means a great advantage. Corridor. The corridor is made of steel and ( be removed with the picture glass pi as a unit. The cleaning^ thereof is that reason very easy. The film is h through the corridor by means of t springs and pressed against the pictv glass plate by a frame of German sih Cache. j A cache arrangement is placed bef | 2 Main Objecl^-*'^-r \ ObjechVes.
