Abstract

Automatic indicator of kilometric distances, characterized in that it will be constituted by an elongated sheet folded in two on itself, in each of whose parts a circle will be represented that carries internally a series of numerical signs arranged in an approximately circular and concentric form, which carry marked a circular crown, on its perimeter, divided into boxes or sectors, in each of which will appear the name of one of the populations that contains the map that will serve as a comparison, being the box or upper sector of each circle provided with a signaling arrow pointing upwards. On this elongated sheet and on each one of the circles that it has, two equally laminar circles will be superimposed, subject to it by means of rivets that at the same time will act as axes, so that they can rotate freely in any direction on them. Each one of the printed circles and whose rotating circles will have practiced a series of windows or squares coinciding with each population of the map, by which each one of the corresponding kilometric distances will be observed at each moment, so that freely rotating such circles, their windows or boxes indicating the populations will be made to coincide with the situation in the circles indicated in the basic sheet of the kilometric distances marked on them, indicated in the circular crown by means of its large signaling arrow, the population to be compared must match the notch or angular cut of the rotating circles, giving, place to that in each moment, they appear in the corresponding squares the exact kilometric distance, between a certain population and all the others existing in the map that must appear represented in each rotating circle.
