ABSTRACT:
The present invention is a spring motor providing an efficient storage of mechanical energy, translating the potential energy of wound springs to mechanical rotation. The invention includes a frame supporting two gears having peripheral teeth. A first coil spring is positioned about a first shaft and is attached to the first gear and the frame. Similarly, a second coil spring is positioned about a second shaft and is attached to the second gear and the frame. The peripheral teeth of the two gears engage with each other so that rotation of the first gear causes rotation of the second gear. The first and second coil springs are opposingly wound so that potential energy stored in the first coil spring is mechanically transferred, in an oscillating manner, to the second coil spring through rotation of the gears. A chain is attached to the peripheral teeth of the gears so that the chain is linearly displaced as the gears oscillate. Means is provided for transforming the linear displacement of the chain to rotational displacement of the first or second gear.
