A Non-Intermittent High-Speed 16-Mm. Camera

A rather simple form of non-intermittent 16-mm. camera that seems to be especially well suited for high-speed motion-picture photography has been developed. Film under tension is pulled continuously by a sprocket across a gate that has an aperture enlarged in the vertical dimension. The image is displaced optically to follow the film by means of a uniformly rotating plane parallel plate of glass located between the lens and the film. Framing is accomplished by small uniformly rotating blades, the edges of which follow the frame lines of the picture down as the film moves. — The camera can be run at speeds as high as 2500 pictures a second. Two forms of the camera have been developed for use with the precision liming clock, one designed for race timing by the Kirby system, having an operating speed of 120 frames per second, the other using a camera with a maximum speed of 2500 frames per second.
