4. Car Pullers Number Four and Five: Car pullers number<br />
four and five, designed by the Stephens-Adamson Manufacturing<br />
Company, are also 10,000 pounds continuous reversible wire rope<br />
and car puller machines. It served the north and south<br />
stockhouse sinter fines bins at blast furnace number six. The<br />
south stockhouse f s power equipment is arranged and driven in much<br />
the same manner as car puller number three except that the motor,<br />
drive, and winch drum assembly is laid out on a north-south,<br />
rather than east-west axis. The motor, gear drive, and winch<br />
drums sit on top of a steel column supported platform<br />
approximately 4'-o" above grade and are located 2l , -0" east of<br />
the sinter fines bins centerline, 107'-6" south of the centerline<br />
of blast furnace number six. The system is connected by two 7/8"<br />
diameter steel cables. The cable which is wrapped around the.<br />
winch drum south of the motor and gear drive provides an anchor<br />
for the system. It is tied to a steel frame located 12*-0"<br />
directly south of the winch drum. The cable which is wrapped<br />
around the winch drum north of the motor and gear drive travels<br />
around nine 24" diameter sheave wheels laid out in a 207'-0" long<br />
x 30*-0" wide rectangle which surrounds the east and west sinter<br />
fines tracks and before returning to the winch drum. Attached to<br />
the taut steel cable rectangle near the southern end of its<br />
eastern border and near the northern end of its western border is<br />
a sling assembly equipped with a "C" hook which is used to tow<br />
the railroad hopper cars onto the east and west sinter fines<br />
tracks. Car puller number five, located in the north stockhouse,<br />
is a mirror image of car puller number four.<br />

in. ore Yard:<br />
A. Ore Yard: The 226'-0" wide x 1653'-0" long x 26'-0" deep<br />
rectangularly shaped ore yard is laid out on a north-south axis<br />
to the west of blast furnaces number one through six. It is<br />
doglegged by 3 degrees for a distance of 544'-0" on its southern<br />
end. The ore yard wall, which encompasses its north, east, and<br />
west sides is constructed of rough faced ashlar. The eastern wall<br />
is 7'-9" higher than the western wall. Along the top of the east<br />
and west ore yard walls are rails for the ore bridges to travel<br />
on. Construction Date: 1895 - 1897.<br />
iv. ore Bridge:<br />
A. Ore Bridge Number Three: Ore bridge number three was<br />
designed and built by the Heyl and Patterson Company in 1954 and<br />
is laid out on an east-west axis across the ore yard. Made out<br />
of riveted construction, it consists of a pier and shear leg<br />
which carry a 333'-0" long x 20 l -0" wide Warren bridge span. The
