I propose to employ the vulcanized or prepared wood in the form of boards or planks set with glass for making floors, area-coverings, and roofs. When for making curved roofs, the boards or planks are to be bent by any well-known process of bending wood previous to being cured. I propose to also make use of the preserved wood as mounts for glasses, as shown by Figs. 5, 6, 7, to be combined with an iron frame or a wood foundation; and I also propose to make use of the wood in the form of large mounts or quarries to hold a number of glasses, as shown by Figs. 8, 9, 10. The mounts I propose to make in any geometrical or ornamental form.     In employing the preserved wood for elevator-doors, as represented by Fig. 11, I may in some cases combine the glass-set wood planks with a wrought-iron frame. It will be readily seen that this new material for making patent-light constructions affords a wider scope of utility and ornamentation than can be had with metal, together with freedom from being affected by heat and cold and changes of temperature, as is the case with iron. As to the fire-proof quality of constructions made of preserved wood, I propose to meet this point by overlaying the wood with some fire-resisting material.     Having thus fully explained the nature and scope of my invention, what I claim, and desire to secure by Letters Patent, is--     1. Illuminating-gratings made of vulcanized wood and set with glasses, substantially as and for the purposes herein set forth and illustrated.

2. Illuminating floors, roofs, and roof-pavements made of vulcanized wood set with glasses, substantially as and for the purposes herein set forth and illustrated.     3. Illuminating-grating risers, treads and steps, and step-roofs made of vulcanized wood set with glasses, substantially as and for the purposes herein set forth and illustrated.     4. Illuminating mounts and quarries made of vulcanized wood set with glasses, substantially as and for the purposes herein set forth and illustrated.     5. Illuminating gratings, mounts, or quarries made of natural wood preserved against decay by charring, smoking, saturating with oil, with or without pressure, oxidation, chemical impregnation, creosoting, burnetizing, or otherwise being treated chemically, as herein set forth, or by processes analogous to the ones herein mentioned, and set with glass, for use as vault-covers, floors, roofs, and roof-pavements, substantially as and for the purposes herein set forth and illustrated.     6. Illuminating-grating elevator-doors made of vulcanized wood, or of preserved wood, and set with glasses, 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:     T. C. BRECHT,     L. W. SINSABAUGH.
