Transmitting mechanism for driving music boxes, consisting essentially of a shaft provided with a crank, which is coupled with a pinion with which they mesh constantly and independent of each other, two gear wheels arranged on a rotating insert mounted on the axis itself, being each of said wheels being able to engage separately, by angular displacement of the carrier plate by reversing the rotation of the crank with one or other, respectively, of those of another pair of toothed wheels, meshed with each other and conveniently facing them, a of which is linked directly to the element receiving the movement and through the second previous inversion of the rotation of the crank, so that it always turns on both sides, in the same direction.
