over an extension at the rear of the ground-floor or principal story, illustrating the window nature of the vertical portions of the roof, and also illustrating a mode of arranging the daylight-reflectors in curved and arch form to produce a finish and an ornamental appearance at the rear of the apartment.     Fig. 4 represents a glass sliding register-riser. A indicates the levels, treads, or flat horizontal portions of the roof. B indicates the vertical, riser, or window portions of the roof. C indicates the daylight-reflectors, a indicates the front slide of the glass register. b indicates the back or rear slide of the glass register.     Having thus fully explained the nature and purposes of my invention, what I claim, and desire to secure by Letters Patent, is--     1. An illuminating step-roof wherein the daylight-reflectors or reflecting-surfaces are made or arranged in line, resembling leaves, louvers, or slats, and placed at a reflecting-angle underneath or below the treads, so as to catch and reflect their light, substantially as and for the purposes herein set forth and illustrated.     2. An illuminating step-roof, in combination with a sidewalk and principal story of a building, when the steps are formed by combining glass sliding register-risers with illuminating-treads, substantially as and for the purposes herein set forth and illustrated.     3. An illuminating step-roof, in combination with a sidewalk and principal story of a building when the steps are formed by combining glass sliding register-risers with illuminating-treads and daylight-reflectors, or with reflecting-surfaces, substantially as and for the purposes herein set forth and illustrated.     4. An illuminating rear-extension "lean-to-roof," the incline of which is broken or divided into alternate vertical and horizontal

sections, the proportions of one to the other being such as to prevent obscuration of light from snowfalls, substantially as and for the purposes herein set forth and illustrated.     5. An illuminating rear-extension lean-to-roof, the incline of which is broken or divided into alternate vertical and horizontal sections, the proportions of one to the other being such as to prevent obscuration of light from snow-falls, in combination with daylight-reflectors, or reflecting-surfaces made or arranged in line, resembling louvers, leaves, or slats, and placed at a reflecting-angle underneath or below the levels or horizontal sections, so as to catch and reflect their light, substantially as and for the purposes herein set forth and illustrated.     6. An illuminating step-roof, in combination with the rear extension of the ground-floor or principal story of a building, when the roof is composed of illuminating-levels or horizontal sections, combined with and connected by risers or vertical roof-sections having the function of windows, and likewise combined with daylight-reflectors or reflecting-surfaces made in the form of slats or louvers, and arranged in semi-dome or arch form, substantially as and for the purposes herein set forth and illustrated.     7. An illuminating roof or skylight combined with daylight-reflectors or reflecting-surfaces made in the form of slats or louvers arranged in semi-dome or arch form, substantially as and for the purposes herein set forth and illustrated.     In testimony whereof I affix my signature in presence of two witnesses.
