Length-Measuring Instruments Using Mechanical Means
(AREA)
Abstract
Improved drawing instrument, essentially characterized by comprising a ruler and a bevel, so that the bevel can slide along the entire length of the ruler without changing the angle of placement at any time, the rule being provided with a notch or recess longitudinal, intended to accommodate a male of the same section provided in the lower internal area of the small side of the bevel and the rest of this side being small inclined at the top so that, when the coupling of both elements occurs, the male enters in the notch and the bevel is mounted and fixed on the ruler, determining an invariable right angle, graduated on its sides and susceptible of longitudinal displacements.
