This invention relates to improvements in roongtiles,'and has for its object to provide a tile formed of cement which shall be light, strong, and impervious to moisture.

A The invention consists in the parts shown in the drawings, described in the specilication, and pointed out inthe claims.

1n the drawings, Figure 1 is a plan view of the outer side or face ofone of my improved tiles; Fig. 2, a Vertical section thereof in line A B of Fig; 1; Fig. 3, an edge viewlooking from theright side of Fig. 1; Fig. 4, a plan View of the .under side lof said tile; Fig. 5, a horizontal section in line C D of Fig. 1; Fig. 6, a section` in line E F of Fig. 1; Fig. 7, a plan of a series or number of rows of tiles made to conform to my invention and iitted to interlock with each other; Fig. 8, a vertical sectionin line I K of Fig. 7; Fig. 9, asection of a series of interlocked tiles in line L` M of Fig,l 7; Fig. 10, a horizontal section in line G H of Fig. 7'. The tiles hereinafter described are made of ceinena'sand, and .water pr'gperly mixed to form a mortar which will dry in the open air Without the use ofarticial heat or a dryingroom, but need onlyto' be ."placed under an open shed'tobe'protected from the weather.

Roong-tiles formed of this material have proved of superior quality v and are light, strong, and impervious to moisture and are of small cost compared with tiles or roof-covering made of other material having like durabi'lity. Tiles made of this material must be so formed that they will iit snugly and securely together, and by my improved form 'and construction of tile this is fully accomplished Without the employment of nails,wire, or other separate vfastening devices, and a tile is produced which will fully answer all required purposes. Y

, My improved tile, as clearlyV shown upon the outside section, edge, and under side in the rst four figures of the drawings, is molded to the form of a square plate 1, a number of which are placed in diagonal tiers or rows, as shown in Fig. 7, with thetwo lower lap edges 2 of each tile having a downwardly-projectingv bead 10, which rests above and upon the two upper lap edges 3 ofthe other or adjacent tiles next below it. In order to secure this lap-joint, the opposite horizontal corners of each tile are cut off in parallel lines 4 of the diagonal length of the lap edges 2, and thus allow the tiles to abut solidly at their adjacent corners one against theother.

The two upper lap edges 3 have a channel, I

V5, running parallel to the adjacent sides of thetilefrom.Y the lower ends of the cornerlines 4 of the tile until they meet at right angies at the upper corner of the tile, and the said channels 5 arebounded on the outside by a raised bead 6, which merges into an outer groove 7 atthe very edgeof the tile. The groove 7 is used as a mortar-groove and extends Afrom a short distance above the upper ends of the corner-lines 4 to the apex of the tile and is easily reached from the inside to be filled or pointed vup'eith'er when the tiles` are laid or afterward should the joint require attention.

Upon theunder edge of the tile, asshown in Fig. 4, a'piocket or recess 8 is formed beneath the .extended portion of the b ead' and between the lower end of the mortar-groove 7 and the horizontalcorner'rof the tile to receive each one of the sides and ends'of a retaining-nose 9, formed to project downwardly from the under side ot the tile, as will hereinafter appear.

A bead l0 is formed on the under side of the tiles to extend from the horizontal corn ers parallel with the two lower sides until they meet above the lower corner or point of the tile, the said bead l() being so located that it will snugly Iit into the channels 5 upon the upper face and lap edges 3 of the tile and serve as the principal means for interlocking the tiles together.

A mortar-groove ll is formed at the edges of the parallel corner-line which abut against each other at the said horizontal corners and provide a useful and conveniently-located means for holding the four meeting corners of the tiles together.

The tiles rest upon purlins or small strips of wood secured to the rafters of the roof and are each intel-locked with one of said purlins by a hang-nose l2 at the under side of the apex or upper corner thereof, which extends below the said purlin, as clearly shown in Fig. S of the drawings, and together with the retaining-nose 9 atthe lower part of the tile will securely hold the tile upon the roof, when they are made to interlock with each other, as above described.

A hub 13, with star-points extending therefrom upon the under side of the tiles, comes directly over the purlins and maybe supported thereby and raised to insure tightlytilting Contact with the roof and with each other besides serving to greatly reinforce the tiles.

I claim as my invention and desire to secure by Letters Patentl. A tile made in the form of a square plate having its side corners cut away, two upper lap edges having an inner channel and a raised head, and two lower lap edges, each having a head to tit the said channels of the upper lap edges, a retaining-nose extending downwardly from the underside and lower corner of the tile and recesses adjoining the upper ends of the said corners to receive said retaining-nose, substantially as described.

il. A tile made in the form ot a square plate having its side corners cut away and mortargrooves formed in the edge thereof; two upper lap edges having an inner channel, a raised bead and an outer mortar-groove, and two lower lap edges, each having a bead to iit the said channels of the upper lap edges, a retaining-nose extending downwardly from the under side and lower corner of the tile and recesses adjoiningthe upper ends of the side corners to receive said retaining-nose, substantially as described.

In testimony whereof I aflix my signature in presence ot' two witnesses.

GUSTAV SCIIULZE.
