Like many mill-style buildings of the time, the Twohy’s loading doors (in this case, the delivery wagon doors) opened to an elevator shaft. This design cut down on loading time, as long as the elevator was operational. Of course, if it was otherwise occupied, there could be no traffic through the exterior doors!
The underground portions of the engine shop were mostly filled in.
In the middle of Electric Steel, dust collector vents cross-cross out of sight.
An unplanned skylight. It’s unclear why some parts of the building had wooden roofing, while others were highly reinforced with brick.
The gothic landing between balcony and classroom level and the ground floor.
Heavy wood doors for keeping people in.
The factory’s first aid room and laboratory. Sure makes me wonder how safe the lab was!
