In an aircraft wing lift increasing device including a vane and flap positioned and functioning in accordance with a Fowler flap action or principle and which includes means for mounting the vane and flap independently of each other but in sliding relation to their wing structure for the purposes of extending and retracting them in an efficient aerodynamic relationship, an improvement for actuating the vane in proper and efficient relationship to the flap in such extension and retraction modes, and comprising in combination, foldable linkage means comprising a pair of rigid members hingedly attached together at their adjacent ends, the respective free ends of said members constituting a forward end and a rear end for said linkage means, respectively, means for biasing said members towards an unyielding, unfolded position for said linkage means, a cam member in fixed and non-rotatable relation to and mounted on said forward end for rotation with its rigid member as said members unfold and fold, said forward end and cam member being adapted for rotation about the mounting means for the vane, and means mounted on the wing structure and upon which said cam member engages as said linkage means movingly folds and unfolds during the extending and retracting modes for the vane and flap, said cam member being disposed forwardly of said mounted means and with folded position for its linkage means, said cam member engaging said mounted means to prevent extension of the vane as the flap extends until the flap extends to a point at which said linkage means becomes unfolded to cause said cam member to become disengaged from said mounted means to provide for extension of the vane as the flap continues to extend, said cam member with its unyielding, unfolded linkage means being disposed rearwardly of said mounted means, the vane remaining extended until said cam member engages said mounted means as the flap is retracting, such engagement overcoming said biasing means to break the unfolded linkage means, said linkage means continuing to fold to a point where said cam member disengages from said mounted means to thereby provide for retraction of the vane as the flap continues to retract.
