The slope, glass or metal, was probably intended to drain whatever water did get into the window, so it wouldn't drip down the backs of those seated alongside the windows. If they were originally glass, the sightline would not have been so important, but if metal, it would have been.
The glass line is well outboard of the seat backs -- the thickness of the masonry wall intervenes. But the drainage issue is pertinent nevertheless . . .
And, wind-blown rain and sea-water are now presumably excluded from the living room. It would be interesting to have occupants' accounts of these matters.
One sees here, on Sheet 6 of the original Walker house working drawings prepared at Taliesin under FLlWâ€™s direction and signed by him, hinged Â½-inch thick painted plywood lipped panels as the vent flaps. Half of the panel thickness was inset into openings bounded by the zigzag-shaped vertical stanchions and the outboard horizontal formed steel angles that ran continuously. The inboard angles run between stanchions, and the flaps were shown to be secured to the inboard, formed angles with piano hinges. (The geometry of their proposed operation was not fully studied or worked out with the preparation of this drawing.)
The house was not outfitted with the full complement of operative vent flaps shown on the drawings, but adequate cross ventilation was provided for the Living Room. In these glazing arrays, the upper two â€œshelvesâ€� were constructed very similarly to as shown in the drawing, but with the painted plywood panels installed as stationary closures. In No. 2 of DRNâ€™s lovely photos posted on Page 1 of this thread, one may observe the quarter-rounded â€œlipsâ€� of the fixed panels that constitute the upper two â€œshelves.â€� In No. 7 of DRNâ€™s photos the lipped edge of the fixed panels forming the upper â€œshelfâ€� can also be seen. DRNâ€™s No. 4 photo shows from the interior the undersides of the fixed wood closures in their freshly and excellently painted condition last year.
Imagine approaching the accomplishment of a full implementation of the ventilation indicated on the cross section drawing of the Living Room, and a few things quickly come to mind: one would begin to appreciate how awkward the physical operation of the 4-foot long vent flaps would be, at least from the interior. There was no readily available friction-type hardware that might hold them in other than a vertical, â€œflappingâ€� position such that they would obscure visibility almost catastrophically for this circumstance; and there is no easily executed provision for inclusion of insect screens. Returning to DRNâ€™s No. 2 photo, one can see the interior surface of the lowest â€œshelfâ€� at the near corner. Looking over and past the glass ball floats one sees on the shelf a dark shape. This is one of several screened vent openings that are positioned in the lowest "shelf" around the Living Room. In DRNâ€™s No. 1 photo, one can somewhat discern several linear shadows on the interior of the lowest â€œshelf.â€� Those are these vent openings. Each is fitted on the interior with a sliding panel about 16 inches long, easily and gracefully finger-operated by the lady of the cabin to suit outside air circulation needs irrespective of open or closed exterior doors . . .
I would have to think that similar means of ventilation is provided for each bedroom in the lower â€œshelfâ€� of the glazing array that runs along that wing of the house, but I have not personally observed those elements.
"Plywood vent openings in living room and bedroom
glazing to be provided with two catches and two fric-
tion adjusters per each _____ _____ section. Large
glazed doors shall have casement fasteners etc etc. . ."
Quite right that sliding vent doors would be much easier to manipulate than the drop-down ones ?
