bracket-hangers strips forming a substructure, which strips are so formed on their upper faces and sides as to form a mold, corresponding to the inwardly-projecting flanges on the bracket-hangers, in placing the material on this substructure and inwardly-projecting flanges, and finally removing the substructure, leaving the same supported solely by the bracket-hangers, substantially as described.     3. The herein-described method of constructing an illuminating pavement, consisting in supporting a substructure on which to "lay" the pavement and which forms a mold for the same, by bracket hangers which, in the finished pavement, form a part of the pavement and support the edge thereof; placing the lenses and spacing them apart with plates which form a mold bottom for the concrete therebetween; and removing the substructure and the mold plates between the lenses, all substantially in the manner and for the purposes specified.     4. The combination with the removable construction strips, for supporting a concrete pavement while in the course of construction and forming a mold therefor, said strips being formed with inclined sides and a deep longitudinal groove in their lower sides, through the medium of which deep groove the strips are compressed or pinched away from the material, of the detachable bracket-hangers for supporting the ends of the strips and for supporting that edge of the finished pavement, substantially as and for the purposes specified.     5. The combination with bracket-hangers provided with means for mounting the same upon a suitable support, of flanges extending from their inner lower edges, said flanges being so arranged as to receive the substructure into pockets formed by the flanges, and the substructure having its upper face conforming to the arrangement of the flanges and having a longitudinal slot for adjustment through the medium of a securing bolt between the brackets and substructure, substantially as described.     6. The method of constructing an artificial stone illuminating pavement, which consists in arranging the bracket hangers in position, which bracket hangers form a permanent support for the finished pavement, placing in position a substructure which is formed with grooves, corresponding to the ribs of the finished pavement, extending in an outward direction from the building, placing the lenses in position on the crowns formed by the

substructure, which crowns in the substructure form the space between the ribs, laying the pavement in the grooves and between the lenses to the top thereof, and finally removing the substructure, substantially as described.     7. The method of constructing an illuminating pavement by the use of a temporary substructure, which consists in laying the pavement on the substructure, forming ribs on its under side during the course of laying, which ribs run toward the building, and in embedding the lenses in the pavement between the ribs, and finally removing the substructure, when the pavement will be supported at its edges by permanently located hangers, which are cut out between the ribs so that the light through the lenses may pass obliquely and unobstructedly into the basement or area to be illuminated, substantially as described.     8. The method of constructing area spanning illuminating pavements, which consists in arranging bracket hangers at the side or sides of the area which hangers are cut away at their lower edges to correspond to the contour of the finished pavement, in building a sectional substructure by arranging beams at right angles to the building, which beams are so shaped on their upper faces as to form ribs on the under side of the pavement, which ribs run toward the building, in supporting on said substructure the lenses, in laying the pavement on the substructure, between the lenses, and to the top thereof, and finally removing the substructure, substantially as described.     9. The combination with an area spanning illuminating pavement which is formed with ribs on its under side running toward the building, the lenses thereof being embedded in the pavement between the ribs, and bracket hangers which support the edge of the finished pavement, said bracket hangers being cut away on their lower edges to correspond with the spaces between the ribs, whereby the rays of light passing through the lenses, may pass obliquely, in the direction of the ribs, beyond the line of the bracket hangers, which bracket hangers are cut away to permit the unobstructed passage of such rays of light, substantially as described.     In testimony whereof I have hereunto affixed my signature, in presence of two witnesses, this 26th day of April, 1893. PRESTON M. BRUNER. Witnesses:     A. RAMEL,     HUGH K. WAGNER.
