Applied Motion Study
A Collection Method to industrial Preparedness

CHRONOCYCLEGRAPH DEVICES 79 It was possible to make fairly satisfactory rec- ords of workers and of surroundings, equipment and tools with an ordinary camera. These were supplemented by descriptions in great detail of the best methods observed, even to the making of diagrams showing the relative location of the worker’s feet and the position of the working equipment. Through such records conspicuous wastes in human energy became at once appar- ent, and various inventions of devices that cut down the amount of effort necessary, or elimin- ated needless fatigue, were made.1 With these inventions, and the comparison of the motions re- sulting from them with the motions used before the inventions, there was instantly an added ap- preciation of the importance of a study of the elements of the motions themselves. With the writer’s acquaintance with Dr. Tay- lor and his epoch-making discovery of the neces- sity for recording unit times, came an added ap- preciation of the need for including time study with motion study. The great problem was to record the motions used. The cinematograph was finally resorted to as an accurate recording i See “ Bricklaying System,” Myron C. Clark, Chicago, Ill.
