Improvements in turntables, consisting of mounting the intermediate friction wheel that drives the disk support plate, freely rotating on the free end of an oscillating arm about an axis parallel to the pivot of the plate and sliding longitudinally with respect to it, elastically requested from In this manner, the wheel tends to be applied simultaneously against the flange of said plate and against the motor shaft which is provided with different diameters, corresponding to the different speeds, said arm being additionally provided with a follower that engages with a cam of helical profile corrugated, connected to the speed control of the apparatus and whose rotation provides to said arm the longitudinal movements with respect to the motor shaft for the change of speeds and oscillation movements between each two coupling positions, to separate the wheel from friction of said tree.
