VAULT-COVERING OR ILLUMINATING-GRATING AND SURFACE MADE THEREFROM. SPECIFICATION forming part of Letters Patent No. 288,572, dated November 13, 1883. Application filed October 19, 1883. (No model.) Patented in England March 4, 1874, No. 783.

To all whom it may concern:     Be it known that I, THADDEUS HYATT, a citizen of the United States, residing at the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Vault-Coverings or Illuminating-Gratings and Surfaces made therefrom, of which the following is a description, reference being had therein to the accompanying drawings, making part of this specification.     My invention relates to the construction of illuminating-sidewalks or area-coverings in the front, and of rear-extension roofs at the backs of buildings designed for stores.     The object of my improvements is to cheapen such work and make it better and handsomer.     The novel features that constitute the invention are: first, illuminating-gratings made in the shape of web-and-flange beams or bars; second, web-and-flange illuminating-gratings made with scalloped edges or open-side light-holes; third, illuminating panel-gratings constructed of web-and-flange-bar gratings; fourth, illuminating panel-gratings constructed of web-and-flange-bar gratings made with scalloped edges or open-side light-holes; fifth, illuminating surfaces, roofs, and pavements constructed of web-and-flange-bar gratings; sixth, combined joint-glasses and cement for closures to seams between gratings made with scalloped edges or open-side light-holes in illuminating constructions; seventh, illuminating ornamental slate or imitation slate roofs; eighth, illuminating non-dripping condensed-moisture roofs.     In the drawings making part of this specification like letters refer to like parts in all the figures.     Figures 1 to 9 refer to bar-gratings and bar-grating constructions. Figs. 10 to 13 refer to ornamental slate constructions. Figs. 14 to 17 refer to non-dripping condensed-moisture roofs. Fig. 18 represents in cross-section a bar-grating ridge-and-furrow illuminating-roof. Fig. 1 is a plan view representing a web-and-flange-bar grating formed with open-side light-holes or a scalloped edge. Fig. 2 is a panel-grating made of bar-gratings such as are represented by Fig. 1. Fig. 3 is a cross-section of Fig. 1, with the web placed uppermost; as in making roof constructions. Fig. 4 is a

cross-section similar to Fig. 3, but with the web downward, as in making floor and pavement constructions. Fig. 5 is a plan representing a web-and-flange-bar grating made with whole holes. Fig. 6 is a panel-grating made of bar-gratings such as are represented by Fig. 5. Fig. 7 is a perspective view representing a rear-extension curved illuminating-roof constructed of scalloped-edge bar-gratings. Fig. 8 is a plan view representing a sidewalk-light or area-covering constructed of scalloped-edge bar-gratings. Fig. 9 is a cross-section of Fig. 8 on the line x x. Fig. 10 is a plan view representing an illuminating ornamental slate-roof construction. Fig. 11 is an enlarged view in cross-section of one of the slates. Fig. 12 is a plan view representing another mode of making illuminating ornamental slate roofs. Fig. 13 is a cross-section of Fig. 12 on the line y y. Fig. 14 is a plan view representing a cast-iron roofing-plate formed with whole and half light-holes or a scalloped edge, and with a guttered top face for catching the drippings of condensed moisture from a glass weather-surface placed above it. Fig. 15 is a cross-section of Fig. 14 on the line z z. Fig. 16 is a plan view representing two plates like Fig. 14 when united at their scalloped edges. Fig. 17 is a cross-section of Fig. 16 on the line 1 2. Fig. 18 is a view in cross-section of a ridge-and-furrow roof made of illuminating L or angle-iron gratings.     A indicates a web-and-flange-bar grating formed with scalloped edges or open-side light-holes.     B indicates a web-and-flange-bar grating formed with whole holes and straight edges.     a indicates half-holes.     b indicates whole holes.     c indicates the flange part of the bar.     d indicates the web of the bar.     e indicates the crack or seam between the abutting edges of two meeting bar-gratings.     D indicates glasses.     e' indicates waterproofing-cement around the glasses and in the seams between the glasses.     B indicates the front wall granite piers, and F the side walls of the building.     G indicates the granite coping at the ends of the area.     H indicates a sill-riser or supporting-bar
