Tahawus in Essex County, New York — The American Northeast (Mid-Atlantic)
A LOOK INSIDE
The water cascading over the wheels, the hissing pistons, and the exposed gears, connecting rods, and crankshafts must have made the wheel house a dynamic and noisy place. Cutaway view shows the inside details of the wheel house.
Based on drawings by the Historic American Engineering Record.
THE WHEEL HOUSE
You are looking at the remains of a timber-faced stone dam on the Hudson, and rusted pieces of water-powered machinery. Three overshot water wheels drove a blast engine that forced air to the blast pipes in the furnace, pumped water to cool the tuyeres, and powered the drop stamps on the charging bridge.
Four cast-iron blowing cylinders forced air from here to the hot blast stove, a brick structure on top of the furnace; there the air was heated to 500 degrees F by waste gases rising from the stack. The hot air was then forced down to the hearth through a cast-iron pipe called a downcomer.
The water wheels turned a drive shaft that extended from here to the charging bridge where it supplied the power
Cast-iron nozzles, called tuyeres, blasted super-heated air on the fire, raising the hearth temperatures to 2500 degrees F. A belt driven pump, powered by the water wheels, supplied cooling water from here to prevent the tuyeres from melting in that intense heat.
