Gravity engine 1


A way to bring some weights into action consecutively in a gravity engine. Press pink arm, red slider moves back, to start the engine. When the first yellow weight contacts cyan lever, it brings the second weight into action. Turn the green shaft counterclockwise to get initial position. Blue gears are connected to the output shaft by one-way clutches of ratchet pawl (or roller) type. The output speed control device (retarder) is not shown. Springs that force red sliders towards yellow racks are not shown. Instead of rack pinion drive a cable drive can be used.
