How ammunition reached an 8-inch turret stacked on a 12-inch turret

How did an early American battleship feed an 8-inch turret mounted directly above a 12-inch turret?

Two additional ammunition hoists are recalled as passing through the lower 12-inch mount to supply the upper 8-inch turret.

The arrangement places an 8-inch turret directly above a 12-inch mount. Two extra ammunition hoists are recalled as passing through the lower turret to supply the upper guns. This compact layout sought a useful heavy secondary battery within the cost and size limits of the hull. Separate positions for the 8-inch guns would have required a larger ship. The arrangement is judged unsuccessful despite the appeal of concentrating firepower in a small space.
