ABSTRACT:
The mechanism is to apply drive in both directions of rotation to a ring having an inside set of teeth, the drive being applied by means of a pivoting handle. The ring cooperates with two locking pawls mounted on a stationary cheekplate and with a toothed slug pivotally mounted on a cam and forming two drive pawls, the cam being pivoted by the handle, but with a certain amount of diametral clearance. When the handle is pivoted, the drive pawl corresponding to the pivot direction engages the toothed ring while the other drive pawl is held in a retracted position by a stationary slideway, and the locking pawl corresponding to the pivot direction of the handle is moved into a retracted position by the cam while the other locking pawl engages the toothed ring.
