Applied Motion Study
A Collection Method to industrial Preparedness

— 66 APPLIED MOTION STUDY ously. Our latest microchronometer records in- tervals of time down to any degree of accuracy required. We have made, and used, in our work of motion study investigations of hospital prac- tice and surgery, one that records times to the millionth of an hour. This is designed for ex- tremely accurate work, but can be adjusted to intervals of any length desired, as proves most economical or desirable for the type of work to be investigated. Having completed our microchronometer, we proceeded as follows: The microchronometer was placed in the photographic field near the operator and his working equipment, and against a cross-sectioned background or in a cross-sec- tioned field, and at a cross-sectioned work bench or table. The operator then performed the op- eration according to the prescribed method, while the motion-picture camera recorded the various stages of the operation and the position of the hand on the microchronometer simultaneously. Thus, on the motion picture film we obtain inter- mittent records of the paths, the lengths, the di- rections, and the speeds of the motions, or the times accompanying the motions, these records
