of the furnace is located 35 , -0" from the building's northern
wall and 31'-0" from its western wall.
The casing and motor for the clay gun, manufactured by the
Bailey Company, and the Woodings Industrial Corporation air drill
are laid out linearly on a north-south axis at the eastern side
of the furnace. Resting on the craneway east of the mud gun and
air drill is a Sheppard/Niles 10-ton crane. The control room
contains a snort wheel, a signal box from blow engine house
number two, and various switches and gauges pertaining to the
cooling water system, hot blast temperature and hot blast
pressure. A manually operated lever and pulley system leading
upwards to the bleeder stacks at the top of the furnace is
located in each corner of the cast house.
Leading from the iron notch on the eastern side of the
furnace are the remains of the iron runners, which consist only
of the slightly sloped 4'-6 1/2" wide x 2'-0" deep x 22'-9" long
iron trough. Two slag runners extend from the "monkey" at the
northern side of the furnace. One runner travels in a northerly
direction, the other in a northeasterly direction. Each runner
emptied out into one of the slag pit's two sections.
Approximately 20'-0" below the cast house floor on its eastern
side are the standard gauge railroad tracks where two "submarine"
ladle cars were spotted in order to receive molten iron while the
furnace was tapped.
Original construction date: 1896.
Rebuilt: 1924.
Construction of iron and slag runners: 1969.
Installation of crane: 1924.
Installation of clay gun and air drill: 1962.
B. Remains of Cast House Number Two: The remains of cast
house number two consist of its brick walls surrounding the
remains of blast furnace number two.
Original construction date: 1896.
Rebuilt: 1924.
C. Cast House Number Three: Built around blast furnace number
three, cast house number three is laid out on a east-west axis.
It is 70'-0" wide x 103'-0" long x 30'-0" high to the bottom
chord of the truss. A steel framework encased by the brick walls
is supported by the building's concrete foundation. Four equally
spaced riveted cambered fink trusses running in a north-south
direction support the building's louvered 1/4" thick steel plate
gable roof. Extending from the eastern wall of the building is
an approximately 20'-0" high x 30'-0" wide craneway running in an
north-south direction. Constructed off the southern inside wall
of the building is an approximately 8'-0" wide x 30'-0" long x
