NEARLY THE SAME, ALTHOUGH BY A DIFFERENT METHOD, AN INVENTION FOR LIFTING WEIGHTS.

A detailed technical engraving of a heavy-duty crane or derrick mechanism positioned on a cliffside. The machine consists of a thick vertical pillar supporting a horizontal boom reinforced with diagonal struts. A system of ropes and pulleys is used to lift a large, rectangular stone block from a small boat on the water below. On the right side of the pillar, two men are operating a complex winch and pulley system to provide the mechanical advantage necessary for the lift. The background shows a rugged coastline and water.
