Scale model of a massive steel geared pulley for steel mill. Geared pulleys such as this were used in the days before mills and factories were electrified, to transfer mechanical power from an engine room (i.e., a massive steam engine) to individual factory machines via an elaborate network of ropes and pulleys.
