Description
Kirk's patent solves the problem that previously "skylights were ventilated by slatted openings under their gable-ends, through which impure air passed off." His "invention consists, first, in providing a galvanized-iron skylight with a double gutter - one for the putty by which the glass is sealed, the other to receive and conduct off the water or moisture that may drip into it; second, in providing for ventilation an air-duct under the gable of the skylight, into which air may enter through holes or openings, and be conducted out through openings at the ends of said air-duct, and similar ducts extending down the sides to the eaves of the skylights, by which all dust, soot, or rain are prevented from entering..."
