Winch

Argano per sollevare i pesi

In this detailed exploded diagram, Leonardo describes a winch that can transform the alternated motion of a lever in the continuous circular motion of a shaft. Each movement of the lever activates one of the toothed rims, which is then blocked by the corresponding wheel by two spring teeth. The two toothed rims alternate in transmitting the movement produced by the lever. The shaft, which can only rotate in one direction, prevents the fall of the weight and facilitates the lifting.
