Free run clutch apparatus

A damper assembly for dampening movement of a device connected to said assembly, said assembly comprising:

• a housing defining an enclosure:
• a rotor rotatable located within said enclosure, said rotor defining a cavity and a column;
• a shaft having a first and a second end. said first end of said shaft being rotatable disposed within said cavity:
• and
• a coil spring coated with black oxide, said spring having a first extremity and a second extremity, said second extremity being attached to said first end of said shaft;
• a wherein said column extends through said spring such that when said spring is rotated about said column in a first direction, said spring runs freely about said column and when said spring is rotated in a second direction opposite to said first direction about said column, said spring tightens into driving engagement with said column.

A free run clutch apparatus for damping movement of a device mechanically connected to said apparatus, said apparatus comprising:

• a housing defining an enclosure;
• a rotor rotatably located within said enclosure, said rotor defining a cavity and a column;
• a shaft having a first and a second end, said first end of said shaft being rotatably disposed within said cavity;
• a biasing device having a black oxide coating material applied thereto, said biasing device having a first extremity and a second extremity, said second extremity being attached to said first end of said shaft, said biasing device being disposed within said cavity between said first end of said shaft and said rotor such that when said shaft is rotated in a first direction, a free run of said biasing device within said cavity is permitted and when said shaft rotates in a second direction opposite to said first direction, said coated biasing device grabs said rotor so that damping of said rotation of said shaft in said second direction is achieved, said biasing device being a coil spring, said coil spring expanding and moving about said column when said shaft is rotated in said first direction, said coil spring contracting and tightening about said column so that said rotor can rotate when said shaft moves in said opposite second direction;
• said black oxide coating material being a conversion coating formed by a chemical reaction produced when said biasing device is immersed into an alkaline aqueous salt solution;
• said chemical reaction being produced when said biasing device is immersed into an oxide bath containing said salt solution in order to produce a magnetite coating on said biasing device;
• said coating material being a black oxide coating material;
• said apparatus further including:
• a wax applied to said biasing device for additional lubricity and rust protection;
• and
• said rotor being made from NYLON 66.
