  Large gears whirl around the edge of a large metal chute in the center of

the ceiling.  Giant, moving, metal rods with brass balls on the end radiate

out from a ring around the chute.  Various extremely large arches, catwalks

and crawl spaces lead to other parts of this monstrosity that whirls about. 

Upon one of the large supporting iron columns is a small tin plaque bolted

in twenty spots.
