A metallic roof-pavement or sidewalk composed of metal beams and metal plates, in combination with a trottoir or foot-surface made of Portland cement or of hydraulic concrete combined in plastic condition with the plates, substantially as and for the purposes herein described.     2. A metallic roof-pavement or sidewalk composed of perforated or grating metal plates and metal beams, in combination with a trottoir or foot-surface made of Portland cement or of hydraulic concrete combined, when in a plastic state, with the metal plates, substantially as and for the purposes herein set forth and illustrated.     3. A metallic roof-pavement or sidewalk composed of perforated or grating metal plates and metal beams, in combination with a trottoir or foot-surface made of Portland cement or of hydraulic concrete combined with a protecting under face of like material, substantially as and for the purposes herein set forth and illustrated.     4. A metallic roof-pavement or sidewalk composed of perforated or grating metal plates and metal beams, in combination with a trottoir or foot-surface made of Portland cement or of hydraulic concrete combined with a protecting under face of like material brought down in cantalever fashion upon the bottom flanges of the beams, substantially as and for the purposes herein set forth and illustrated.     5. A metallic roof-pavement or sidewalk composed of perforated or grating metal plates and metal beams, in combination with a trottoir or foot surface made of Portland cement or of hydraulic concrete combined with an under face of like material brought down between the beams under the plates in mass sufficient to weight the structure and produce the necessary vis inertiæ to enable it to resist impact and concussions, substantially as and for the purposes herein set forth and illustrated.     6. A metallic roof-pavement or sidewalk frame or skeleton composed of metal plates and metal beams combined to form the foundation for a concrete metallic structure, substantially as and for the purpose herein set forth and illustrated.     7. A metallic roof-pavement or sidewalk frame or skeleton composed of metal plates and metal beams (wherein the plates are perforated or grating plates) combined to form the foundation for a concreted metallic structure, substantially as and for the purposes herein set forth and illustrated.

8. A safety-surface metallic roof-pavement or sidewalk composed of metal beams and perforated or grating metal plates cast with gutters between rows of perforations, in combination with a concrete trottoir or foot-surface laid between the gutters in strips, substantially as and for the purposes herein set forth and illustrated.     9. A safety-surface metallic roof-pavement or sidewalk composed of metal beams and perforated or grating metal plates cast with gutters between the rows of perforations, in combination with a concrete trottoir or foot-surface set with glasses between the gutters, substantially as and for the purposes herein set forth and illustrated.     10. A safety and dry sidewalk or pavement for the purposes of a public footway, wherein the safety and the dryness of the trottoir or foot-surface are obtained by a combination of metal gutters with concrete.     11. A safety and dry sidewalk or pavement for the purposes of a public footway, wherein the safety and the dryness of the trottoir or foot-surface are obtained by combining concrete with metal gutters laid or made to run in a diagonal direction to the sidewalk or line of travel over it.     12. A safety-surface metallic roof-pavement or sidewalk composed of metal beams and perforated or grating metal plates cast with gutters between rows or lines of perforations, in combination with concrete in strips put in between the gutters, wherein the gutters and strips run or lie in a diagonal direction to the sidewalk or course of travel over it, substantially as and for the purposes herein set forth and illustrated.     13. A safety-surface metallic roof-pavement or sidewalk composed of metal beams and plates cast with gutters, in combination with concrete in strips laid in between the gutters, the same lying or running diagonally (or otherwise) across the face of the pavement.     14. As a manufacture or article, a cast-metal pavement-plate formed with safety-channels, in combination with non-slipping or foot-holding material put between the channels, substantially as and for the purposes herein set forth and illustrated.     15. A cast-metal pavement-plate formed with safety-channels, in combination with non-slipping or foot-holding material between the channels combined with glasses to give light, substantially as and for the purposes herein set forth and illustrated.     In testimony whereof I affix my signature in presence of two witnesses. THADDEUS HYATT. Witnesses:     S. BACON,     W. E. CHAFFEE.
