An automatic device for touching and changing discs constituted by a single-phase motor from whose transmission the speed variations are achieved by means of a control that coaxial to a helix determines with its rotation the ascent according to a number of positions equal to the various desired speeds of a piece. With notches adapted to the edge of the profile of the propeller so that also ascends a wheel of horizontal plane and elastic rim that is driven by a spring acts according to its positions on one of the different sections of the axis that communicates the movement whose variation of diameters determines the gear shift. By communicating the movement to the rotating disc supporting the rotating discs of a coaxial pinion thereto is derived the operation of the automatic disc change mechanism.
