Abstract: When time-motion curves are plotted from high-speed films, the feeding steps of the tracing paper must be exactly proportional to the time interval between frames. Ordinarily the length of each feeding step must be determined by a preliminary measurement of the frame rate. This inconvenience is avoided by the procedure described here, which consists in photographing on each frame of the film a timing instrument with a rotating scale. The film analyzer is equipped with a duplicate of the timer dial, and the rotation of this duplicate dial is proportional to the movement of the tracing paper. As the film is advanced from one frame to the next, the paper is advanced independently until the dial on the analyzer stands at the same position as the image of the dial on the new frame of the film. The feeding step of the tracing paper is thus automatically proportional to the time interval between the new frame and the preceding one. The ratio of the rotation of the dial to the linear feed of the paper can be varied to give any desired time scale for the resulting time-motion curve.
