New model of compass perfected for ellipse tracing characterized by consisting of two arms of variable separation at will finished in tip for its better adaptation to the foci of the ellipse to be drawn and to which the ends of a length adjustable wire segment are joined equal to the major axis of the ellipse problem, which passes through a hole made in a third arm in which the action of a spring forces the thread to be held taut so that the sum of the distances from the end of the tracer arm to the ends of the other two are constant, and so when the tracer arm is provided with a pencil, line pencil or equivalent element, this, when the arm moves, draws an ellipse of focal length and major axis.
