Torque transmitting apparatus

In an apparatus for transmitting torque to a load, the improvement comprising;

• a long endless belt;
• a pair of pulley means vertically spaced apart by a great distance for movably mounting said belt in a substantially vertical disposition to move it freely in a closed loop path;
• a plurality of spaced apart arm devices connected to and extending from said belt and movable along said path alternatingly vertically upwardly and vertically downwardly;
• a plurality of weights adapted to be carried by said arm devices, each one of said arm devices having one of said weights mounted thereon movable between an outer position away from said belt when falling vertically downwardly and an inner position near said belt when moving vertically upwardly, said weights and said arm devices being arranged in pairs, each one of the pairs of weights and arm devices providing a larger moment acting through said belt on at least one of said pulley means when falling vertically downwardly under the force of gravity and alternately providing a relatively smaller opposing moment when acting through said belt on at least one of said pulley means when being pulled vertically upwardly by said belt;
• means coupled to at least one of said pulleys for connecting it drivingly to the load;
• and
• gravity-actuated means for moving said weights to their inner positions as they commence moving upwardly and for moving said weights to their outer positions as they commence falling downwardly.
