In a thrust reverser translating mechanism, a drive shaft and a driven shaft are connected so as to permit a small degree of relative rotation. A pawl is pivotally connected to the driven shaft and an annular ratchet surrounds it. If the drive shaft controls the speed of rotation, it takes up the free movement and in so doing, moves the pawl out of engagement with the ratchet. If the driven shaft attempts to rotate faster than the drive shaft, it takes the pawl away from its engagement with the drive shaft and allows resilient means to urge the pawl into engagement with the ratchet thus stopping rotation of the driven shaft until the drive shaft catches up and disengages the pawl from the ratchet again.
