ABSTRACT:
A mechanical proportioning trim execution device has a fulcrumed lever which swings between fully retracted and fully advanced positions. The fulcrum is movable back and forth from a neutral point along a fulcrum path. The lever has a fulcrum-engaging slideway extending in skewed relation to the length of the lever such that when the lever is in fully retracted position the fulcrum path and slideway are parallel but become increasingly skewed as the lever moves toward the fully advanced position.
