tending through and dividing the lens-sockets of one row and avoiding the projecting knobs, in combination with a supporting-girder arranged beneath said row of sockets, and with blind lenses set in said sockets, substantially as set forth.     6. A composite illuminating-tile consisting of two or more illuminating-sections fitting together edge to edge, the line of their junction extending diagonally back and forth in zigzag direction through a row of lens-sockets, substantially as shown, and for the purposes set forth.     7. The combination of an illuminating-section, D, having one or more sides formed in a zigzag outline, and provided with half-lens sockets on said zigzag side, said half-sockets having bottom webs, in combination with another like section having a zigzag edge fitting to and interlocking with that of the first section, substantially as set forth.     8. The combination of two or more illuminating-sections, D D, adapted to bridge an opening or vault, and to fit together edge to edge, with a margin, F, extending along the edge of the opening, cast or formed in one piece with the illuminating portion of the sections, and that on one section forming an uninterrupted continuation of that on the adjoining one, substantially as set forth.     9. The combination of two or more sections of illuminating-tiling adapted to be laid side by side and fitting together edge to edge, so as to produce a continuous illuminating-surface, and each formed with a margin, F, cast or made in one piece with the illuminating portion of the sections, so disposed that when the sections are laid together to form a composite tile the

margin will extend around the outer edge thereof and surround the entire illuminating-surface, substantially as set forth.     10. The combination, with sectional illuminating-tiles formed to fit together edge to edge, and so produce a continuous illuminating-surface, of a sectional border of checkered or otherwise ornamented non-slipping surface, arranged to surround the illuminating-surface when the sections are laid together, and provided with deep grooves at intervals simulating and parallel with the joints between the sections, substantially as set forth.     11. The combination, with illuminating-sections D D, formed with a recessed margin, F, of sectional border-plates f f, having a checkered or other anti-slipping upper surface fitting into said recessed margin, substantially as set forth.     12. The combination, with plate or section D, of the fastening for confining it to the stone, consisting of diagonal hole h in the latter and pin or spike i set in said hole, and its head overhanging the edge of the plate, and with the border-plate f f fastened over and concealing said pin, substantially as set forth.     13. The combination of stone B and girder E with spur d on the latter projecting diagonally downward into the stone, substantially as shown and described.     In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
