Abstract
A gravity motor which is formed of at least one motor unit which has at least one motor member fixed to an output shaft. The output shaft is rotationally mounted on a housing. The housing includes a guide surface. The motor member is low frictionally longitudinally movable relative to an output shaft. Each end of the motor member includes a weighted follower which is low frictionally movable relative to a guide surface. The rotation of the motor unit will cause one weighted follower to be moved toward the output shaft by the guide surface with the opposite weighted follower of the motor member being moved away from the output shaft. The result is gravity produces an overall clockwise torque on the motor member which causes rotation of the output shaft.
Claims13
A gravity motor having at least one motor unit which is formed of at least one motor member which comprises:
- an output shaft having an axis of rotation, said output shaft being rotatably mounted to a housing;
- a hub having a through hole defining an elongated axis, said output shaft being fixed to said hub so said axis of rotation is located substantially perpendicular to said elongated axis;
- a first sleeve mounted to and extending from said hub, said elongated axis being centrally located relative to said first sleeve;
- a second sleeve mounted to and extending from said hub, said elongated axis being centrally located relative to said second sleeve, said second sleeve located in alignment with said first sleeve;
- a connecting rod mounted within said first sleeve and said second sleeve and said through hole, said connecting rod being low frictionally longitudinally movable relative to said first sleeve and said second sleeve and said through hole, said connecting rod having free ends one of which protrudes exteriorly of said first sleeve and the other of which protrudes exteriorly of said second sleeve;
- a weighted follower mounted on each said free end with there being a pair of said weighted followers;
- a guide surface mounted on said housing, said guide surface to be contactable by each of said weighted followers;
- and
- whereby said guide surface causes said connecting rod to extend outwardly so said follower not in contact with said guide surface is located a substantially greater distance from said hub than said follower in contact with said guide surface which results in an overall clockwise torque caused by gravity which thereby causes rotation of said output shaft about said axis of rotation.
A gravity motor having at least one motor unit which is formed of at least one motor member which comprises:
- an output shaft having an axis of rotation, said output shaft being rotatably mounted to a housing;
- a connecting rod diametrically mounted within said output shaft, said connecting rod being low frictionally longitudinally movable relative to said output shaft, said connecting rod having free ends;
- a weighted follower mounted on each said free end with there being a pair of said weighted followers;
- a guide surface mounted on said housing, said guide surface to cause movement of a said weighted follower that is located directly adjacent said guide surface in a lineal direction toward said output shaft;
- and
- whereby said guide surface causes said connecting rod to extend outwardly so said follower not located nearest said guide surface is located a substantially greater distance from said output shaft than said follower located nearest said guide surface which results in an overall clockwise torque caused by gravity which thereby causes rotation of said output shaft about said axis of rotation.
