Abstract
A compass, essentially characterized by the fact that it is constituted in such a way that the upper extremities of its branches are adjusted by means of a rack system formed by two semipigons formed in them held together, so that they can only move by angularly projecting the branches of the compass inside of a limit that goes from a point where they are held together and parallel to another in which they form an angle of approximately 180 degrees, by means of two lateral and parallel elements that compress between them such extremities keeping them under a pre-established pressure by corresponding screws or rivets that passing through holes made in them, they also act as support points on which the branches or arms of the compass rotate.
