Abstract: A mechanical rectifier efficiently rectifies or converts alternative clockwise and counterclockwise rotation of a main handle or other active driving element into unidirectional rotation of a main shaft. This mechanical rectifier is useful in manual tools such as a "no-waste screwdriver", which eliminates the wasted hand motion inherent in all ordinary hand tools, and in energy-saving devices such as a wave-powered electrical generator. The basic mechanical rectifier includes a shaft, two driving elements, and a reversing mechanism coupling the two driving elements so that they can only rotate in opposite directions. Each of the two driving elements has a separate one-way roller clutch pressed in its bore in proper orientation and riding on the shaft so that, whichever direction a driving element is rotated, it always turns the shaft in the same direction. Therefore, a tool bit at one end of the shaft always serves to tighten a fastener, while a tool bit at the opposite end only serves to loosen a fastener.
