Use as a historical infrastructure mechanism. The Stitzel patent is an archival lead for independent verification when exact priority or design detail is consequential.
A documented technology sequence linking machinery and patent design to warehouse architecture.
Raitz explains that industrial hoists solved vertical barrel movement, while Frederick Stitzel’s modular 1879 rack allowed barrels to be stored in stacked rows with airflow and independent access. Together with monitor-roof ventilation, these changes made multistory warehouse form more practical.
