DESCRIPTION
I. Electric Furnace Building and Lean-to:
The electric furnace building is located at the northern end
of the lower works near its far western side. Constructed by the
American Bridge Company and laid out on a north-south axis, the
steel framed building is 237'-0" wide x 897'-2" long x 77 '-0' 1
high to the underside of the truss. It has a corrugated metal
exterior with louvers on all four walls. The stock house aisle
of the building has a slightly pitched roof which is supported by
riveted Pratt trusses. A gable roof supported by riveted Warren
trusses with riveted I-beam bracing extending downward from the
underside of the roof to the top chord of the truss covers the
charging and pouring aisles. A 15'-0" wide x 450'-0" long x 12'-
0" high lean-to is built onto the eastern wall of the building.
A. Stock House Aisle: The 82'-0" x 460'-2" long stock house
aisle is located on the western side of the building. It
consists of two floors. The ground floor covers the entire aisle
while the second or scrap make-up floor consists of a 29'-6"
extension of the charging floor on the eastern side of the aisle.
Running the length of the aisle, the scrap make-up floor is
located 20'-0" above the ground floor. It carries two parallel
narrow gauge tracks. The outside track runs outside of the
southern end of the building and alongside the outside western
wall of the charging aisle on a I8 f «0" wide x 195'-0" long
trestle extension of the floor. The total space occupied by the
scrap makeup floor and its extension provides sufficient space
for forty-three charging-box cars.

floor are eighteen aS'-O" square x 5'-0" high scrap stock bins.
Two standard gauge railroad tracks run through the center of the
aisle for its entire length. Located on the ground floor, 32'-0"
