Applied Motion Study
A Collection Method to industrial Preparedness

46 APPLIED MOTION STUDY From the data on the film and the observations of the observer, can be formulated an improved method. The standard method is seldom derived from the work of one observed worker only. It has been noted that the ideal method seldom lies in the consecutive acts of any one individual; therefore, many workers are observed before the final standard is deduced. These micro-motion records give all the data required except the continuous path of a cycle of motions. This lack is supplied by the chronocy- clegraph method. The chronocyclegraph method of making motion study consists of fastening tiny electric-light bulbs to the fingers of the operator, or to any part of the operator or of the material whose motion path it is desired to study. If it is merely the orbit of the motion that is to be observed, a photograph is made of the moving part to which the light is attached, during the time that this part is performing the operation. If the direction, relative time, and relative speed are to be noted, the path of light, through con- trolled interruption of the circuit, is made to consist of dots or dashes, or a combination of the two, with single pointed ends,— the point show-
