The anchors rest upon a cast iron foundation plate connected, through
strong bolts embedded in the pedestal, with a second plate resting
upon the concrete.
As the metallic framework was calculated for resisting the wind, the
brick lining does not rest against it permanently above. The weight of
the chimney is 1,112,200 pounds, and the foundation is about 515
square feet in area; and, consequently, the pressure upon the ground
is about 900 pounds to the square inch. The cost was $3,840.
[Illustration: FIG. 3--VERTICAL SECTION OF THE CHIMNEY.]
The chimney was built six years ago, and has withstood the most
violent hurricanes.
The mounting of the iron framework was effected by means of a motor
and two men, and took a month. The brick lining was built up in eight
days by a mason and his assistant.
A chimney of the same size, all of brick, erected on the same
foundation, would have weighed 2,459,600 pounds (say a load of 3,070
pounds to the square inch), and would have cost about $2,860.
The chimney of the Rocourt distillery is, therefore, lighter by half,
and cost about a third more, than one of brick; but, at the present
price of metal, the difference would be slight.
