In addition to this leakage effect, the two coils co-operate to maintain a magnetic flux throughout the entire 994,043. iron path of reactance il , and thereby operate to smooth out the current in the load circuit 14. No. 994,042. Film Moving Mechanism. Charles R. Uebelmesser, New York, N. Y., assignor to American Moving Picture Machine Company of same place. The entire novelty of the patent is shown very clearly by the illustration. A long path is taken from the middle of the take-up reel to the upper steady feed sprocket, the two ends of the reel of film are spliced together, and the projection may be continuous if desired. A novelty in the take-up magazine is found in the method of driving the reel of film, or rather the ring of film, since it forms into a ring in the magazine, with a large open center from which the upper feed receives it. In this magazine the ring of film is driven by rollers placed in the floor of the magazine, and which bear only upon the edges of the film, not upon the face nor upon the margins having the sprocket holes. Of the twenty claims, the first and last are broad and typical: 1. In a film-actuating mechanism, means for driving a film by frictional contact with the edges thereof. 20. A film-actuating device comprising a base and a series of positively driven rollers therein having their upper surfaces in a plane at right-angles to the axis of a film-coil, and means for delivering the film to said rollers with its edge in contact with said surfaces. The reflecting mirror 46 is moved into "frame" with the image in the film, and at the same time the lens 50 is kept in focus. The inventor's description of operation and his claims are as follows : The film is placed between the orifices 17 and 44. By the simple manipulation of the adjusting handle 33 it may be moved until one of the pictures thereon registers with the inner orifice 44. When light is passed through the film -the light rays will take some such paths as those indicated by broken lines and will be reflected through the lenses in holder 50 so that the picture may be projected upon a screen or other surface. Now a rotation of the shaft 20 will cause the film to be drawn downward with a continuous movement. At the same time the portion 38 of the cam groove, acting through pin 43, will cause the reciprocatory member 40 with its orifice 44 and reflector 46 to be moved downward in unison with the film. If the mechanism for sliding the lens holder is used the lens holder will at the same time be drawn inward. The projected picture upon the screen will therefore remain stationary. When the film has been drawn down a distance approximately equal to the width of one of the pictures the portion 39 of the cam groove will engage the pin 43 and cause the reciprocatory member to be quickly raised until its orifice and reflector are in alinement with the next succeeding picture on the film. This upward movement may be made as quickly as desired as it is obviously merely a matter of proportioning the two parts of the cam groove to obtain the desired proportion of downward and upward movements in each cycle of operation. When the bell-crank lever 55 is used this upward movement of the member 40 will push the lens holder out again to its first position so that the focus will be maintained. With this machine the use of a shutter is not necessary, although, of course, one may be added if desired. When this apparatus is used as a camera only such changes as will be obviously apparent to one skilled in the art need be made. By way of suggestion, some of these obvious changes are the addition of a shutter over the lens and the provision of a light tight inclosure for the sensitized film. The cam 37 may also be modified to suit the new conditions. This invention I believe to be basically new, and the appended claims are intended to cover the invention broadly and are not to be interpreted to be limited to the exact mechanisms which I have described as an illustration of one of the manners in which the invention may be carried into effect. What I claim is : 1. In a moving picture machine, a single fixed reflector, a movable reflector, and means for intermittently moving the No. 994,043. Framing Device for Moving Picture Machine.
