"DEVICE FOR THE DETERMINATION OF CURVES OF CONSTANT VALUE BETWEEN DIFFERENT POINTS" which is characterized by being composed of a frame in the form of an articulated parallelogram, capable of being fixed in any angular position, between whose larger sides are stretched resistant threads fixed at distances equal in the internal edges of said sides, so that each thread coincides with a division marked with the corresponding numerical indication of the curves to be determined, so that the relative position of two points of known value and joined together being determined in a plane points by means of a straight line, one of the rules is placed so that one of the points is placed in coincidence with the graduation of the rule corresponding to its measured value and the other point coinciding with the own value reflected by the corresponding threads , for which the parallelogram is tilted until obtaining the aforementioned coincidence, done as l, it is fixed in said position and the points of intersection of the threads are marked with the line joining the two points considered, whose points of intersection are located in the curves of constant value to be determined, which are plotted by similar operations.
