Motography (Jan-Jun 1915)

1048 MOTOGRAPHY Vol. XIII. No. 26. complish the framing in the mechanism of this patent, Mr. Bingham arranges his crank handle so that it may be pushed inwardly or pulled outwardly while being turned at a steady speed of revolution. By pushing the handle toward the body of the Fig. 1,113,664 motion head, the speed of the take-up sprocket is increased and the film is drawn downward through the film window in longer steps, thus framing the picture; by pulling the handle out while turning, the film is framed in the opposite direction. The claims are twenty-eight in number and cover the feature of crankhandle control of framing. 1,123,456. For a Projecting Machine. Issued to Earle M. Wooden, New York, N. Y., assignor of part to A. B. Cavanagh, New York, N. Y. The object of the invention is to provide a partial illumination of the screen during the usual dark Fig. 1,123,456 interval of the picture shift, with a view to reducing or eliminating the flicker. This object is attained by making the film window a little larger than the film image, so that light may pass at the margins; then the shutter is so shaped that it interrupts the light from the image but not the light through the margins. 1,123,689. For improved Feed Sprocket Detail. Issued to C. D. Condon, Boone, Iowa. This improvement has to do with Fig. 1,123, the handling of the film as it passes over the upper steady-feed sprocket. The sprocket is shown at B. The guide roller a guides the film to the sprocket. The presser roller C holds the film upon the sprocket, and a "take-off" roller D lifts the film from the sprocket. A novel feature is found in using the same pivot screw for supporting the rocking bracket of the presser roll C and for a spindle for the "take-off" roll D. 1,123,665. For Improved Framing Mechanism. Issued to George W. Bingham, New York, N. Y. The film shift is of the type wherein the film is grasped by a clamp device and pulled down, the sprocket holes not being used for alignment of the shift or for framing. Two rollers, normally not revolving, pinch Fig. 1,123,665 the film between shifts to hold it firmly and motionless in the film window. These rollers may be turned by hand of the operator to frame the picture, being disengaged from the film while the film is shifting by the intermittent mechanism, and framing it by moving it during its intervals of rest. 1,124,253. Lens System for Color Photography. Issued to Maurice Audibert, Villeurbanne, France. Not specifically designed for motion picture color photography, but it is of interest Fig. 1,124,253 to all experimenters in color photography. The lens system comprises a large negative front-lens and then several smaller positive lenses behind it for forming several images, each through a color screen. 1,124,367. Slide Holder. Issued to Clarence W. White, North Bennington, Vt. The invention covers a slide holder which may be rotated a quarter turn. This is of particular value in projecting the so-called "foreign" slides, which are square and are likely to get into the slide holder on the side. Other advantages are for showing special slides, and for lecture work. 1,124,635. Lighting of Motion Picture Auditoriums. Issued to Frank G. McPherson, Beaver Falls, Pa., assignor to Shadolite Manufacturing Co., Inc., Beaver Falls, Pa. Lamps for illuminating the auditorium are mounted upon the ceiling, and 89 IS 80 IS MV'^ .■■li U| 'T'"lA^'"-il'Yr:yl-ll'iiv''t;T ' \:iW;Z-- m?:---' 88 Fig. 1,124,635 are so protected by shades that the screen is shaded, and the angle of light upon the floor of the theater is limited, the object being to light the room without direct light upon the picture screen or into the eyes of the patrons. 1,124,971. Moving Picture Projector. Issued to E. J. Swedlund, Williston, N. D. This machine projects a picture from a steadily moving film strip. The lens is composed of two parts, a stationary negative lens and a sliding positive lens. The positive lens slides vertically, moving upward at the front of the projecting machine as the film image moves downward in the film window, and as the one image passes beyond the window the positive lens drops quickly to pick up the next image for the rays upon the screen, thus effecting the shift from image to image by a sudden movement of the lens rather than by a sudden movement of the film strip.
