PURPOSE:To obtain a rotating motion by means of gravity by applying the maximum weight to an arm when a gravity unit is sent from the top to a lower point, and applying the minimum weight to the arm when it is lifted from the lower point to the top. CONSTITUTION:A flywheel 2, a cam 3, a sleeve ring 4 and an arm 5 are provided at a main shaft 1, and a slider rod retainer A which has an electromagnetic brake unit 7 is provided at an arm shaft 6. A gravity unit 9 is secured to the center of a slide rod 8, which can be slid by the slide rod retainers A, B. When electromagnetic brake units 7, 11 are operated to feed the unit 9 from the top to the lower point, the maximum weight is applied to the arm 5, and when it is lifted from the lower point to the top, the minimum weight is applied to the arm 5. |
