68,332: 3 of 7

illuminating-roof pavement is my invention, for a roof-pavement in such a combination of glass with iron as to be fit for being walked upon. What I mean to say is that until I did it no area-way was ever covered, and no basement was ever extended under the street by glass and iron combined to form substantially a portion of the sidewalk itself. The extension, where it did exist, was done only by means of a skylight.     What I claim, then, and desire to secure by Letters Patent, is--     1. Forming the approaches over an area-way to the doorways of a building from the sidewalk by means of a solid translucent bridging of iron and glass, which serves the double purpose of stoop and roof, substantially as herein described.     2. Uniting the area-way to the basement of a building by a water-tight roof of iron and glass, so combined as to form a generally-flush surface fit for walking upon, and laid in or nearly in the plane of the sidewalk, substantially as herein set forth.     3. Uniting the basement of a building to the space under the street my means of a translucent water-tight roofed area-way, when the glass and iron which compose the roof are so combined as to form a generally-flush surface fit for walking upon, and are laid in or nearly in the plane of the sidewalk, substantially as herein set forth.

4. Combining an area-light with the sidewalk and a building by means of a double-cemented joint made with putty of its equivalent and fusible cement, substantially as herein set forth.     5. Combining the glass of a roof-light with the iron framing of the same by means of a double-cemented joint, substantially as herein described.     6. An illuminating-roof of iron and glass, where the iron which supports the glasses in position forms the general strength of the roof, the combination being such as to secure the twofold object of equalizing and distributing the strength of the iron while distributing and equalizing the light of the glass.     7. An illuminating step-roof composed of glass and iron-- that is to say, where the iron and glass are composed into illuminating-sills and illuminating-risers, and these are again combined to form an illuminating-roof, substantially in the manner and for the purposes set forth.
