FIELD: plotting of curves. ^ SUBSTANCE: the invention presents a device for simultaneous plotting of different order curves, that is dealt with field of engineering industry. For simultaneous plotting of different order curves the device contains three fixed guides, two fixed axes, the first of which is located in a place of intersection of a horizontal vertical guide and a right-hand vertical guide, the second is located in a place of intersection of a horizontal vertical guide and a left-hand vertical guide. A cruciform lever is installed on the first fixed axis with possibility of twirl. On the second fixed axis there are a two-link cranked lever; fixed rods, each of which has a kinematical connection with the corresponding link of the cruciform lever. At that each kinematic connection joint is supplied with a writing pin. ^ EFFECT: the invention ensures simultaneous plotting of different order curves. ^ 9 cl, 3 dwg |
