Birmingham in Jefferson County, Alabama — The American South (East South Central)
The Stock Trestle
Sloss Furnaces National Historic Landmark
The raw materials for making iron—iron ore, limestone and dolomite, and coke—came to Sloss by railroad and were stored in the stock bins below. An inclined, steam-driven "skip hoist" carried the stock to the top of the furnace and dumped it in automatically. Filling the furnace with stock was called "charging." The automatic charging devices were added to the plant in the late 1920s when the furnaces were rebuilt. Before that time the raw materials were taken to the top of the furnace on a vertical elevator and dumped in by hand.
Charging the furnace was actually accomplished by ingenious arrangement of mechanical equipment. Railroad cars carrying the stock were pushed onto the elevated stock trestle. Doors in the bottom of the cars opened, releasing the stock into the bins below. The bins discharged the stock by gravity feed into a scale car that ran in a tunnel beneath the bins. The scale car automatically weighed each load of material and carried it through the tunnel to the skip pit at the base of the inclined skip hoist. There the scale car dropped the material into a skip car, which was pulled up the incline by a steam-powered hoist. At the top of the car tipped over and dumped the stock into the furnace. The top of the furnace was equipped with a double bell and hopper
Inhaling blast furnace gas was a constant danger for those working at the furnaces, stoves, and boilers, for the gas contained a significant amount of the lethal compound carbon monoxide. The most famous fatality involving the inhalation of gas occurred at Birmingham's Alice Furnaces in 1887. Theophilus Calvin Jowers was killed there while installing a new bell in the top of one of the furnaces. Overcome by gas and heat, he tripped and fell into the furnace. The account of his death in the The Birmingham Age reported that his body was reduced almost to ashes.
According to legend, Jowers's ghost was seen and heard at the Alice Furnaces until they were abandoned in 1927. His ghost then apparently moved to Sloss, where over the years it became part of the city's folk culture.
The circumstances of Jowers's death illustrate the perils of gas inhalation. Some workers said they could see the gas, "a bluish-looking smoke," but other complained that gas leaks around the furnace occurred so frequently that they sometimes breathed the fumes before realizing it. Over the years, the company initiated stringent safety regulations to prevent gas related accidents. Men who worked in the areas where gas was a danger were required to wear gas masks and to notify the foreman when entering a danger zone. Any man working above the receiving hopper at the furnace's top not only had to wear a mask, but also had to be accompanied by two "get-away men" and a respirator. Even when workers followed these measures to the letter, an occasional accident still occurred. Although most workers survived such mishaps, a few were not so lucky.
