RICHARD D WATSON, OF ROCHESTER, MICHIGAN. I

. ROOFING-TILE.

To all whom it may concern:

Be it known that I, RICHARD D. Wx'rsoN,

a citizen of the United States, residing at Rochester, county of Oakland, State of Michigan, have'invented a certain new and useful Improvement in Roofing-Tiles, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the' art to which it pertains to make and use the same, reference being had to the accompanying drawings,

' which form a part of this specification.

This invention relates to roofing tile.

It has for its object an improved tile to be used for covering roofs, side walls and m similar locations in the construction of build-- ings.

Inthe drawing,Figure'1, is a longitu diual section of a number of tiles as they appear in place on the roof slats. Fig. 2, is

longitudinal sectional line a, a, of Fig. 2.-

The tile 1, consists of a rectangular block of artificial stone material, preferably composition made from Portland cement and sand, and is provided on the upper side 80 with convex flutings which broaden at the base or exposed end of the tile. and narrow nearly to a point at the to or covered end bf the tile. Between the utings 2, 3, is a tabular plane 4, which is a plane surface on 85 the upper or partly exposed side of the tile.

On the under side the 'end 51, of the tile has its lower face inclined to the upper face with the thinner edge toward the-covered. end of I the tile and with the thick edge or the thick- 40 ened portion intermediate the two endsof the tile at the

line

6, 6. Alon this line the drop from the lower face oft e tile is sub stantially equal to the thickness of the upper edge of the tile so that the body of the-tile from the upper edge to the lower edge con- 2 stitutes a ock of substantially uniform thickness with a thickened intermediate portion narrowingfrom the

inner line

6, 6 toward'the u per end.

Opposite "t e convexity 2, 3, are cavities 2 3, which rise above the general under sur-' I face of the tile. Between the cavities 2, 3*,

is fastened and brin of the over-lying tlle into close contact throughout its extent with the covered upper is 'a rectangular cavity 7, extendin deep enou h in the body of the idle to orm a cham er for the reception of nail-heads which are driven through the nail-holes 8, in the edge of the under-lying tile. The cavity 7, extends in longitudinal length under the tile sufliciently to cover the two nail-heads of a'n-under-lving tile and sufficiently wide to cover the four nail-heads of the two underlying tile, and the use of this cavity avoids the necessity of drivin the nails entirely home or setting the heads down close to the tile body and consequently avoids the liability of breaking or cracking the tile by driving the nail-heads home. The inclined unspeeincation of Letters Patent. Patented J an. 11,1910. Application filed August 8, 1908. Serial No. 448,584. i

der surface of the upper portion of the tile brings that face of the tile into close contact with the roof boards 9, upon which the tile the under-lying face face of the under-lying tile next adjacent to it, and prevents the liability of breaking the tile when pressure is exerted on its upper surface by walking thereon or placin scaffoldin or ladders'upon or against this portion 0 the tile.

WhatIclaim is: l. A- tile having its exposed face inclined to the central plane thereof, the inclination being continuous from one end to the other, and this surface having tapering convex flutings the entire length thereof, and having its under face terraced transversely intermediate the ends thereof, one of the sections thus constituted being plane and adapted to lie in intimate contact with the roof, and the other section having truncated concaved flutings adapted to engage over thoselpor-' tions of the convexed flutings on the ex osed surface of the adjacent tileimmediately therebeneath, and having between said trun-' cated flutings a cavity for covering nail heads projecting above the adjacent surface scribed.

2.A generally wedge shaped tile, havingouter surface being provided with 'longitudinally extending convex flutings complemenof an underlying tile, substantially as de tarily located with respect to similar though abbreviated concave flutings in one enci of the under surface thereof, and the fluted portions of'the under surface having between them a cavity adapted to cover nail heads projecting above the surface of an underlying tile, emi the opposite end cf the under surface from that wherein said concave flutings ere ie-ceteci being plane and adapted to eeem'? lie in intimate contact with the roof, substentially as described. 1 In testimony whereof, I sign this specification in the presence of two witnesses.
