dead-work borders on the dividing or junction lines, and adapted to abut directly together and form a continuous light-field in panel-spaces, substantially as herein shown and described.     3. Illuminating tiling or gratings made with light-holes arranged on the honey-comb plan or in groups of oblique-angled triangles, and disposed in parallel lines transverse to the light-field, said tiling being divided into fractional sections in transverse lines parallel with and outside of the lines of light-holes, and adapted to abut directly together to form a continuous light-field tile in panel-spaces, substantially as set forth.     4. Illuminating tiling or gratings made with an underlying sustaining-grating of cast iron or other supporting material, and an over-lying facing of concrete or hydraulic cement, and divided into fractional sections adapted to abut together to fill panel-spaces, said sections being made without dead-work borders on their junction sides, and presenting a deep raw or unfinished edge of hydraulic cement at the junction edges, adapted to abut together and be secured in a homogeneous manner with hydraulic cement when laid into their panels, substantially as herein set forth.     5. Illuminating-tiling made in fractional

sections fitted into panel-spaces with their junction edges abutting and secured together and to the panel-frame by cementation, substantially as herein set forth.     6. Illuminating-tiling made in fractional sections fitted into panel-spaces, and secured to the panel-frame and to each other by hydraulic cement deposited in the junction-seams of the fractional sections and in the construction-seams of the panel-frame, substantially as set forth.     7. Illuminating-tiling made with a hardened cement or concrete surface, and divided into fractional sections in lines crossing the light-field, without dead-work borders, and presenting on said dividing-lines raw edges of the cement, adapted to abut directly together and be secured in a homogeneous manner by similar hydraulic cement in a plastic state when the fractional sections are laid into panel-spaces, substantially as herein shown and described.     In testimony whereof I affix my signature in presence of two witnesses. THADDEUS HYATT. Witnesses:     T. C. BRECHT,     E. A. L. HYATT.
