To all whom-it may concern: i
Be it known that I, EDWARD J. WINsLow, a citizen. of the United States, residing at Chicago, in the county of Cook and State of lllinols, have inventedcertain neWand useful Improvements inFireproof Roofing-Tiles, of which the following is` a-specification.
This invention relates to'im rovements in reproof roofing tiles, and it as for its salient objects to provide a construction which combines great strength `and rigidity with lightness and an eIicient form; to provide a construction ini'which the rigidity of the tile against' bending stresses is reinforced by transverse and intersecting"l strengthening ribs formed upon the under side ofthe tile only and the rigidity and strength of the tile is further increased b extending reinforcing wires throu h said' ribs; 4to Iprovide a construction w 'ch is es ecially effective in its lities, the exterior form of theti e being such that the rain cannot beat in or be driven inwardly past the joints by wind; to provide in conjunction with the main tile members ca like batten members which effectively over e and close the joints between the meetin edges of the maintile members; to provi e a construction which acter referre is adapted to be readily and reliably secured to a roof byl means of channel members, Z-y
bars or other commercial shapes of struc,-
tural iron; and in general to roduce an eili-I cient and improved construction of the charuto.
To the above ends the inventionconsists 1n the matters hereinafter described and more artlcularly pointed out in the` ap- The invention willl be readily understood from .the following description, reference bemigi llijadto the accompanying drawings, in w c .Figure 1 is a perspective View of afragmentary portion of a roof covered with tiles embod ing a referred form of the invention; parts eing' roken out .and other parts shown in transverse section; Fig. 2 is a perspective view of the under side of one of the main tile members, parts being broken out to reduce the le th of the /i ure; Fig. 3 is a transverse sectional view t ough a portion of a roof frame andthe tiling thereon,
showing particularly' the manner in which vtile members interlock with4 the supporting irons and the manner in which the cap or batten members overlap the main tile members; Fig. 4 is a fragmentary detail showin the manner in'which the tiles are applied an fit against the base portionl of' a turret or other Fperpendicular wall rising from l the roof; 5 is an end elevation of one of the tiles. yi 6is a fra mentary sectional detail taken vertically and longitudinally throu h .the assembled structure in the plane of t e joint'shown at the left end of Fig. 5.
Describing first in detail the form-and construction of one of the main tile members, 1
designates as a whole one of such members .of the intersecting strengthening ribs hereinbeforedescribed, the main body of the tile is of practically uniform thickness, as indicated clearly in Fig. 5. Extending along its upper margin at the under side thereof 1s a hooke sha ed flange 10 adapted to engage over and hoo upon the edge of a channel member or Z-bar,.,as indicated at 11 and 12. Extending along its lower edge at its under side is a downturned ilange 13" adapted to hookI over the upstanding flange 8 of the tile belonging to the'nextlower tier, as best seen in section of Fi 3. The end margins of the main tile mem ers are ordinarily perpendicular to the main plane ofthe tile, as best seen in Fig. 3, bt lin case the up er end of the Ntile is formed to abut andp t against a vertical wa1l,as for example the base of a turret skyflight, as indicated in detail Fi 4,-.then the correspondin u standing an downturned anges- 8 an `10 will be inclined to the mam plane of the tile so as to abut againstv the vertical frame .structure. i
The longitudinally extending intermediate Vribs 6 are desirably formed by omitting the corrugating grooves of. the under side oppoi .site certain ones of the lridgesrof the upper side, thus forming bars approximately diamond-shaped in cross section but with the lower angle of each bar omitted and a flat face 6 thus formed. The lower sides of these bars 6 extend substantially below the apices 14 of the corrugations of the under surface. form halves of the intermediate ribs; the tile being so formed that its lateral edges are coincident with the apices of the outermost ones of the upper corrugations or ribs. The transverse strengthening ribs are of the same thickness as the longitudinal ribs, lie in the same plane with the latter and are in cross section desirably rectangular, as seen clearly in the perspective Fig. 2. Reinforcingwires are arranged to extend both lon- 'tudinally and transversely through the body of the tile'for the purpose of adding greaterc rigidity and strength to the structure. Describing them, 15 designates transverse wires, of which there are two arranged to extendjthrough each transverse intermediate rib 5 and one through each of theend ribs 4 these wires being located as near the lower outer surface of the respective ribs as prac'- ','ticable without exposing the wires, in order that they may have a truss effect to resist bending stresses brought upon the tile. In the same general way other wires 16 are extended longitudinally through the intermediate and marginal longitudinal ribs 6. It will be understood that both the transverse and longitudinal wires extend the full length and width, respectively, of the tile member; these wires being embedded during the formation of the tile.
As a further feature of the invention, I provide caps of peculiar shape and construction for overlying and closing the' joints between the meeting edges of adjacent tiles. These caps are designated as a whole 17 and each cap is of a length e ual to the length of the tier of tiles to whic it is ap lied. In cross sectional form the main bo y of each cap is that of an inverted V-shaped trough,
the an le of inclination and dimensions 'of the inc 'ned sides'of which conform to and fit upon the corrugation formed by the two meeting edges of the adjacent tiles, as shown clearly in Fig. 5. At its upper end, each cap is provided with an upstanding liang'e 18 which, when the cap is in position, abuts and fits against the sides of the upstanding flanges 8 of the tile members, as seen in Fig.
. 1. At its lower end each cap is provided withiV a downwardly extending flange 19 which hools over theu standing flange 18 of the next lower ca of t e series. The lower edge margin 20 o the downturned flange 19 ofthe cap is of-inverted V-shape to lit accurately upon the downwardly divergent upper surface of the next'lowercap. `Preferably the lateralmargins 21 of the cap members 17 extend to the bottoms 'of the corru- The marginal lateral ribs 6 are in gating grooves of the tile members and fit against the opposed inclined surfaces, as seen clearly in Fig. 5.
With the title and cap members constructed and arranged as described, it will be obvious that the roof surface thus formed presents no recesses or angles in which water, snow or ice may become permanently lodged since the surfaces all pitch downwardly and form unobstructed water-sheds. Moreover it will be seen that the joints are so overlapped that rain or water cannot be driven through the joints beneaththe titles in such manner as to penetrate the roof. The overlapped and interflanged arrangement of the tiles and caps is .of particular importance in making the roof weatherproof against rain accompanied by violent wind. The construction of the tile as a whole is extremely simple and light, and of a form which readily lends itself to molding in a rapid and economical manner.
While the construction described constitutes a preferred embodiment of the invention, it is nevertheless to be understood that the details may be modified to some extent without departing from the spirit of the invention.
I claim as my invention:

A roofing tile formed from plastic material, having a main body member relatively thin and longitudinally corrugated as to both its upper and lower sides, an upstanding flange extending across its upper margin, a downturned flange extending across its upper end margin, a downturned flange extending across its lower end margin, and a plurality of reinforcing ribs extending across the main body at the lower side thereof one or more of which extends across the central part of the tile.
2. A roofing tile formed from plastic material, having a main body of enerally rectangular form and longitudinal y corrugated both as to its upper and lower sides, marginal strengthening ribs extending along each of the four sides of the tile, longitudinal ribs eX tending the length of the tile between the lateral margins l thereof, upstanding and downturned flanges extending across its upper margin, a downturned flange extending across its lower end margin, and reinforcing wires extending through the body ofthe tile.
3. A roofing tile formed from plastic material, having a main body of enerally rectangular form and longitudinal y corrugated both as to its upper and lower sides, integral marginal strengthening ribs extending along each of the four sides of the tile, intermediate longitudinally extending strengthening ribs, intermediate transverseribs, upstanding and downturned flanges extending along the upper margins of the tile, a downturned flange extending across its Plower end margin, and reinforcmg wires extending longitudinally cap member having its under side recessed and constructed to fit upon and overlap'the meeting edges of said tiles, said cap member being provided with an upstandmg flange across its upper end and a downturned flange across its lower end, and beingof a len th slightly in excess of the length of the ties,
