A Collection Method to industrial Preparedness

CHRONOCYCLEGRAPH DEVICES 93 ment in proper placement, since it is often pos- sible to determine through them directly a work- er’s capability of learning and performing the work. The data ascertained by these motion devices are placed upon the Simultaneous Motion Cycle chart. This analyses a motion cycle into its component parts, and indicates graphically by which member of the body, and in what method, each portion of the cycle is performed. The Simultaneous Motion Cycle chart is made on cross-sectioned paper with the various working members of the body used as column headings, and with the sixteen elements of the motion cycle placed vertically on the chart. By the comparison of the analysed motion model with the data on the chart, the possibility of the trans- ference of work from one working member of the body to another is indicated, and the field for in- vention of devices or for more efficient placement is indicated. The Simultaneous Motion Cycle chart that is the outcome of the chronocyclegraph motion devices has been used by the writers for years in the industries, and has been presented by the writers for the benefit of the crippled
