DRAWING DEVICE FOR CONVERTING PARABOLA INTO PARABOLA HYPERBOLISM

摘要

A drawing device for converting a parabola into parabola hyperbolism comprises a vertical guide connected by a first dyad of sliders to a first lever arm, whose second arm is connected by the second dyad of sliders to a first beam, which is mounted in the first dyad of sliders, second and third beams connected to each other by a cross slider. The device is equipped with a horizontal ruler, a hinge, the third dyad of sliders, a T-shaped slider with a stopper. The lever comprises the third arm and is connected to the hinge mounted on the horizontal ruler, on which by the T-shaped slider a vertical guide is mounted and connected by the third dyad of sliders to the third lever arm. The second and third beams are mounted respectively in the second and third dyads of sliders. The lever arms are interconnected forming a T-shaped form, wherein the first and third arms lie on one line.
