Having thus fully set forth the nature and merits
of my invention, what I claim as new is-- 1. An illuminating sheet-metal roofing-tile corrugated upon angular lines, so as to form a series of ridges and grooves, substantially as and for the purpose specified. 2. A roofing-tile having its edges turned upward, so as to be riveted upon the vertical portion of a supporting-beam, substantially as and for the purpose shown. 3. The illuminating sheet-metal roofing-tile |
A, provided with curbed light-openings B b, and combined with the
button-headed lenses C and rubber gaskets D, substantially as and for the
purpose set forth. In testimony that I claim the foregoing I have hereunto set my hand this 14th day of January, 1874.
