![]() This has for its object to prevent the rocker from remaining in any intermediate position which would interrupt the transmission of the drive or in giving rise to idle movement as a result of lagging of the reversal. In the preferred construction according to the present invention, a direct action control device is arranged between the winding pendulum and the rocker in order to move the rocker positively into the new position of engagement upon reversal of the turning movement of the pendulum.
