July 14, 1931. w. A. SUTHERLAND ROOFING TILE Filed July 31, 1928 Patented July 14 q 1931 .-WILLIAM A. SUTHERLAN D, F LOS ANGELES, CALIFORNIA aooFING TILE Application led July 31,

This invention relates to improvements in roofing tiles and the like.

An object of the invention is to provide an improved roofing tile consisting of a back 16j formed of relatively stiff sheet material which back is bent into the form that the fini-shed tile is to take and which has applied thereto one or more layers of a weather resisting adhesive which adhesive has applied thereto a layer of crushed refractory material.

Another object of the invention is to provide a roong tile and a method of making the same which enables the tile to be easily, quickly, and cheaply constructed, but at the same time provides a rooting tile which is extremely durable and which is attractive in appearance.

A further object of the invention is toprovide a roofing tile which is so constructed that materials now available upon the market or which are now in general use, may be employed in its construction. v

With the foregoing and other objects in View which will be made manifest in the following detailed description and specically pointed out in the appended claims; refer- Y ence is had tothe accompanying drawings for an illustrative embodiment of the invention wherein: v

Fig. 1 is a perspective View roofing tile.

Fig. 2 is, a transverse. vertical section through the improved roofing tile. Fig.'3 is a partial vertical section through of the improved a 4slightly modified form of construction.

Referring'to the accompanying drawings wherein similar reference characters designate similar' parts throughout the improved roofing tile in its preferred form, consists of a sheet metal back 10. This is preferably formed of galvanized sheet iron or ainoncorrodible steel so that the back ofthe tile will be weather resisting and will not rust. The particular form given to the back 10 depends upon the form that is to be given to -the finished tile, and in the drawings it is shown as being bent to form a semi-cylindrical portion 11 having a laterally extending horizontal portion 12 along one edge. The

free edge of the. laterally extending portion 12 isbent upwardly as indicated at 13.` A layer of weather resisting adhesive indicated at 14 is applied to the upper surface of the back 10. This adhesive consists of asphaltum, tar, or equivalent substance which will not quickly deteriorate under the influence of weather.

Ithen take advantage of a material now in l general use and which is capable of being' purchased on the market to complete the tile. i

This material consists of a flexible paper backing 15 which has applied to its upper surface a layer of weather resisting adhesive such as tar, asphaltum, or the like, indicated at 1B, and which has a layer of crushed refractory material 17 applied thereto. The refractory material varies in different kinds of this completed material, and in the preferred form' of construction of the improved roofing tile, it is formed of crushed brick which will give the top surface of the tile its color and at the same time affords a protective layer of relatively inert material whichA will not easilydeteriorate under the influence of the Weather:v The layer of paper 15 with its adhesive 16 and crushed brick 17 is applied to the adhesive 14 and pressed smoothly there-over so that the adhesive 14 will fasten it uniformly over the upper surface of the back 10. If desired, the tile may then be placed in a mold to press the layers and cause them to be even although thisis not essential.

While the above described .construction embodies the preferred form of the invention, inferior products can be made by employing other sheet materials for theV back 10 which may or may not have non-corrodible qualities. If desired, wire, preferably in the form of wire mesh, may be substituted for the sheet lmaterial forming the back 10. Such a construction is illustrated in Fig. 3 wherein4 there is a wire mesh back indicatedat 20 to which is applied a layer of adhesive 21 serving to fasten the layer of paper 22, carrying sits adhesive layer 23 and refractory material m24 to the wire mesh 21. Alsosubstitutes for the adhesives 14 and 16 may be embodied which may have weather resisting qualities which are much poorer than those of asphaltum or tar. The refractory material 17 may be changed to produce different appearances and to give the tile different colors such as, for example, crushed slate, crushed rock, or sand vmight be employed.

From the above described construction it will be appreciated that a novel rooting tile is produced which is laminated and which has a metal back to which layers of materiall forming the exterior surface of the tile are applied. The layer of paper, crushed refractory material, and adhesive tend to sti'en the back 10 enabling a very thin sheet metal to be employed, but at the same time producing a inished tile which. is stiif, Strong, and durable. The improved tile has the advan-r tage of being vextremely light in weight so that the load placed on the roof will be a minimum; furthermore, the tile is absolutely water-proof so that no Water can seep through it to rot the Wooden roof construction. Various changes may be made in the details of construction Without departing from the spirit or scope of the invention as defined by the appendedclaims.

AI claim:

l. The method of making roofing tiles and the like comprising preparing exible material consisting of a layer of paper, adhesive applied to the paper, and comminu'ted material applied to the adhesive, forming a layer of sheet material into the form it is desired to give to the finished tile, applying a layer of weather resisting adhesive thereto, and

( then applying the paper with its adhesive and comminuted material to the layer of adhesive on the sheet material.

2. The method of making roofing tiles and the like comprising preparlng fiexible material consisting of a layer of paper, adhesive applied to the paper and comminuted material applied tothe adhesive, cutting a section; of sheet metal to the desired size and outline of the tile, applying a layer of weather resist-N ing adhesive thereto, and then applying the paperfwith its adhesive and pomminuted material to the layer of adhesive on the sheet metal.

In testimony whereof I have signed my name to this specification.
