The “Crinoline” Chimneys of the Cambria Iron Company at Johnstown, Pa
These chimneys (Plate XI) are connected to the boiler-house by underground brick conduits, and are intended as “uptakes” for the unused gases. The surplus gases are used for generating steam, and but little is left after passing under the boilers. Sometimes the fires under the boilers must be reinforced with raw coal, in which case the chimneys convey some smoke. The ground is bad, and hence there is a deep foundation of masonry below the surface. From the entrance of the conduit to about 8 feet above the surface, the base of the chimney is hexagonal, of hammered stone, surmounted by a cut-stone coping.
