DESCRIPTION<br />
A. Rotary Car Dumper Building: The rotary dumper building was<br />
designed by the Heyl and Patterson Company and built by the<br />
American Bridge Company. It is located south of blast furnace<br />
number six near the shoreline of the Monongahela River. Laid out<br />
on a north-south axis, it is 40'-6" wide x 72'-l" long x 17'-8<br />
5/8" high. The steel framed structure of the building is covered<br />
by corrugated metal. The building's gable roof is supported by<br />
Fink trusswork. An approximately 27'-0" wide opening in the<br />
floor runs the length of the building in order to accommodate the<br />
rotary car dumper. Located at the northwest corner of the<br />
building is a 10'-0" square x 9'-0" high operator's room. At the<br />
northeast corner of the building is an approximately 9 f -0 M wide x<br />
10*-0" long x 9 , -0" high motor control room.<br />
Construction Date: 1957.<br />
B. Rotary Car Dumper: The 26'-0" diameter x 60'-0" long steel<br />
framed rotary car dumper, designed and built by the Heyl and<br />
Patterson Company of Pittsburgh, PA, is laid out on a north-south<br />
axis. The centerline of the car dumper is located 22'-2" off the<br />
east wall of the building. Its southern end coincides with the<br />
south wall of the building. Each end of the car dumper is made<br />
up of a braced steel column-like shape formed into a 26'-0"<br />
diameter ring sitting above and below the floor line of the<br />
building. The outside flange of each ring supports one of the<br />
car dumper's two drive chains and a steel rail around its<br />
circumference. Each rail rests on two sets of 12" diameter sill<br />
wheels. The sill wheel sets are composed of two steel rail<br />
wheels which are secured by clevis connections to a large steel<br />
column, laid out on a east-west axis, located directly below each<br />
ring. The columns, which are supported by concrete footers<br />
located in the basement of the building, support the sill wheels<br />
near its eastern and western ends.<br />
The inside flange of each ring forms the parameters of an
