A motion translating and force transmitting device especially as applied to an instinctive wringer includes a rocker arm having wing members thereon which translate pivoting motion of the rocker arm about an axis to either end of a bell crank which is pivoted about an axis parallel to the plane of motion of the rocker arm. Cam means are indexed against a spring loaded index pin and are de-indexed by the reaction of the cam face with a cam shifting pin outwardly from the cam pivot of the operative index. A component of the force of the planar pivoting motion of the rocker arm is transmitted to either end of the bell crank so that, while the bell crank pivots, the moment-arm of the force being transmitted about the bell crank pivot remains constant.
