  • Patent number: 5065686
    Abstract: A batten compression adjustment fitting for use in adjusting the compression of a batten in the sail of a sailboat includes a housing having a batten receptacle that is adapted to receive a batten and a compression adjustment assembly receptacle that is adapted to receive a compression adjustment assembly. The compression adjustment assembly includes an adjustment screw, a traveler that encircles and is freely movable along the adjustment screw and a lock nut that threadably engages the adjustment screw. The traveler has a batten contacting portion that extends into the batten receptacle so as to contact the batten. Upon appropriate operation of the adjustment screw, the lock nut moves along the adjustment screw, thereby causing the traveler to also move and apply a compressive force, via the batten contacting portion, to the batten positioned in the batten receptacle.
