Interpretation by Alberto Mario Soldatini e Vittorio Somenzi, 1957

“Method for making a screw. How the graver for the screws has to be positioned.”

The simple machine is composed of a block with a hole, inside of which a cutting blade is secured. Inside the hole, a nut (female screw) guides the sliding of the cylinder upon which the screws have already been graved.

The model is based on the drawing:
