Power transmission for a thermal elastic wire

A power transmission for a thermal elastic wire comprising a mainframe beam having an intermediate operative portion, a pair of side rails, and forming an extension member

• a pair of opposed anchor posts captured between said side rails and disposed proximate to the opposite ends of said operative portion of said beam, at least one of said anchor posts being adjustably positionable along said beam, said posts projecting effectively perpendicular to said beam and having the free ends thereof adaptable to securing a wire there between, the first of said anchor posts having an extension arm projecting at effectively a right angle there from toward said other post and disposed between said side rails of said beam, said extension arm pivoted at the junction of said first post and said extension arm disposed between said rails for facilitating oscillating partial rotational movement thereof,
• a rotator drum disposed between said side rails of said beam and positioned between said posts proximate to the free end of said extension arm of said first anchor post, said drum being pivoted for oscillating partial rotational movement between said side rails,
• a connecting rod having one end thereof pivotally connected to said rotator drum and the opposite end of said rod extending toward the second of said anchor posts, said connecting rod being curved to conform to a portion of the external surface of said rotator drum.
• a spring member pivotally attached at a first end thereof to said opposite end of said connecting rod, the second end of said spring member being pivotally secured between said side rails of said beam at a position between said rotator drum and said second anchor post, said spring member being comprised of at least one elongated flexible coil spring which fits between said side rails of said beam,
• a bicycle type link chain wrapped around a portion of the periphery of said rotator drum and having one end thereof anchored to said drum and the other end thereof attached to the end of said first anchor post extension arm disposed between said beam side rails whereby as said first anchor post oscillates to move said end of said anchor post extension arm, said rotator drum is rotationally oscillated, and
• a power takeoff connection on said rotator drum for attachment of a connecting link there to, said connecting link being curved to conform to a portion of the external surface of said rotator drum, said power takeoff connection being disposed generally on the opposite side of said rotator drum from said connecting rod connection to said rotator drum.
