DESIGN AND FABRICATION OF MANULLY OPERATED ATHLETIC TRACK MARKER

For sports days or for inter-school carnivals, one of the most important requirements for the trouble-free success of these meetings is that the track and field events be clearly and accurately marked. A minimum amount of equipment is required. Apart from a line-marking machine and some white paint, or other suitable marking material, all that is required is one, or two if possible, good-quality l00 meter tapes, lots of string or twine, a few colored ribbons and a few wooden pegs. For State, National and International competition, athletics fields are permanently laid out and marked with the help of professional surveyors using specialized, expensive equipment for school sports this degree of accuracy is not as critical, a very accurately marked out 400-metre track is possible. In this work, the machine described is an manually operated Line Marking machine that is capable of marking a sports field with the help of limestone material completely manually. This would eliminate the tedious and time-consuming conventional method of line marking manually thus reducing human efforts and increasing the quality of the marking of the sports field. The machine is designed to travel along the path of the field Further, a mechanism for the smooth and continuous release of the limestone marking material is described.
