JOSEPH RAPP, OF NEW PHILADELPHIA, OHIO.
SPECIFICATION forming part of Letters Patent No. 478,171, dated July 5, 1892.
Application filed October 23,1891. Serial No. 409,607. (NomodeL) To all whom it may concern.-
Be it known that I, JOSEPH RAPP, of New Philadelphia, in the county of Tuscarawas and State of Ohio, have invented certain new and useful Improvements in Roofing- Tiles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains tomake and use the same.
My invention relates to improvements in roofing-tile; and it consists in certain features of construction and in combination of parts hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figures 1 and 2 are views in perspective, the former showing the manner of laying my improved tile on the roof and the latter showing the mzltnner of piling the tiles for burning in the ki n.
My improved tile comprises an approximately semi-cylindrical or rounded section A, a fiat section B, and a section 0 at an angle to such flat section. The fiat section has preferably one or more longitudinal grooves b, the grooved portion being provided with the nail-holes, as at Z1, so that the heads of the securing-nails will be out of the way of the overlapping tile. 7 Two corners of the tile that are diagonally opposite, as shown at a and c, are cut away or beveled to serve as a gage in laying the tiles. The tiles are of course laid in lateral tiers, the tier next above overlapping the tier immediately below the necessary distance. The semi-cylindrical or rounded section A of the tile is of uniform size from end to end of the tile, with the upper and under surfaces or sides thereof of such 1 v contour that in laying the tiles thetile next above will overlap and nicely fit the tile immediately below, and that in burning in the kiln the tiles may be laid one above the other as snugly as possible. The rounded section of the tile is provided with longitudinal grooves on its under side, as at a, whereby when the tiles are piled in the kiln to be burned the heat can circulate between the tiles of a pile, and the tiles are not only uniformly burned, but the burning is greatly facilitated. Grooves a also render the tiles lighter, which is very desirable, and admit air to circulate freely between the overlapping tiles, and hence the formation of moisture on admission of Water by capillary attraction between the tiles is rendered almost impossible.
WVhat I claim is 1. A roofing-tile consisting of a rounded or curved section having longitudinal grooves on one of its faces, both surfaces of this section being of such relative contour that it will overlap and snugly fit a like tile, and a flat sec tion integral with one edge of the curved section, the said flat section having holes for and having a section C at an angle to the flat section, substantially as set forth.
In testimony whereof I sign this specification, in the presence of two witnesses, this 29th day of September, 1891.
