FIELD: drawing instrument on geometry to define parabola parameters on the basis of its arc boundary conditions. SUBSTANCE: mechanism to specify initial data is installed on a base. It consists of two connecting links, placed in the direction of tangents of parabola arc. Hinged slide bars are installed on the connecting links with rods providing fixation in preset boundary points of parabola arc. Connecting to the mechanism to specify initial dada is a mechanism of defining parabola parameters comprising three crosspieces, three links of hinged slide bars and a slide bar with rod. EFFECT: easy defining parabola parameters. 2 dwg
